Intrigue :: 2000 3.5L - Vibration And Noise When Turning Left Under Load
May 28, 2013
2000 3.5L
On a hard left high speed turn, it vibrates under load. Also while under throttle when making a second gear left hand turn.
Noise will come and go when going over dips at high speeds under load. I have already replaced the left Half shaft.
I am a master mechanic and have had success with changing a half shaft on a similar situation. Looking for other possibilities before I throw another half shaft at it.

2000 Expedition AWD, 4.6l ... 150K on car, 50K on trans, 150k on transfer case and most else.
The problem is, under load, there is a intermittent bearing vibration noise...it sounds like a roller bearing that has too much tolerance so it vibrates in and out under acceleration. You can feel it in the gas pedal and chassis, you can hear it, and it robs a little power when the sound it pronounced. The sound is 10x worst when towing my 6000lb boat. Gear doesn't seem to matter, but it is hard to make it happen in 3rd gear.
Diagnostics so far:
-Can't reproduce sound on rack or out of gear
-Stethoscoped all accessories - good
-added Lucas oil additive to engine oil - no change
-added Duralube high mileage goop to trans - no change/slight change?
-Aamco said it was transfer case, tear down and inspection revealed nothing, they said it was mostly pristine for a car with 150K on it.
-Inspected U-joints - all tight
The duralube in the transmission may have made a slight difference in the frequency of the sound...but it could be my imagination, it wasn't significant enough a change to be determinate.
I think I could isolate the issue with a diagnostic tool that doesn't exist as far as I know...it would be a handheld device with 4 magnetic mic sensors you could stick in various locations and watch the waveform output on the handheld... you would simply move the mic's around until you got the highest amplitude on the readout.
At this point the only thing I can think of:
-Aamco missed something
-Main bearings, cam bearings, or possibly oil pump
-Transmission bearing (Aamco says "NOT")

So I have a 2004 gti that makes a very loud noise when i turn the wheel even slightly to the left there is also a vibration that shakes the whole right side of the car. I assumed based on the sound and vibration that it was the wheel bearing. the bearing was shot but when i replaced it nothing changed. so it has a brand new wheel bearing and the cv joint is good ive already checked it everything seems to be as it should. i cant think of anything else it could be. What the problem could be caused by?

I have a 2000 Mitsubishi Eclipse GT V6 FWD. about 138, xxx miles
My left rear tire/wheel has free - play (clicking movement) when grabbed at ONLY the 3 o'clock position and push/pulled back and forth (no free-play at 12-6 direction) in the air.
I had grinding noise from rear left side wheel when turning right couple weeks ago. After replacing wheel hub bearing assembly, the noise is gone. But still remains the movement ONLY at 3 o'clock. I replaced stabilizer bar links in both rear sides. This link doesn't look like the reason of free-play (clicking movement).
Also, I tested (push or pull) after switching the other side(right) wheel, it still had clicking movement at 3 pm. Therefore, it is not a wheel problem itself, I guess.
And I took off the wheel and fasten the lug nuts onto the rotor itself (so, without wheel in this case), then push/pull the rotor at 3 pm, but this time no movement in any directions. @@;; weird.. ONLY, I can feel the clicking movement at 3pm on the Wheel (or tire) even after rotating wheel, exactly in same spot (3 pm) movement~!!!! What's this case??
All 4 wheels aligned recently after got new tires.
I scrutinized inside wheel while pushing/pulling back and forth. But I cannot figure out which one is problem.
1. Knuckle.
2. Lower control arm ( or Rear rear control arm, not typo) which has a Ball joint and a cam bolt the other side.
3. Rear front control arm
4. trailing arm.
5. stabilizer bar link. (new)
6. Wheel hub bearing assembly (new, double-checked the nuts and torques)
7. Rotor and pads (new, if I push the rotor itself then no wobble or clicking at all directions as desribed above)
Where should I direct my attention and/or what component(s) should I look at given the indications above?
When I pull/push the wheel at 3 o'clock, it feels like wiggling the whole part of lower knuckle where is the connection part between the part of 4 bolt (backside) of hub assembly and lower side of knuckle.
I heard that 12 and 6 is usually an indication of ball joint, and play 9 and 3 is usually in indication of steering components ( tie rods , steering shaft or rack itself ), and all around play is an indication of wheel bearing (usually accompanied with a growling noise ).

First off my trucks a 2000 v10 f250 with four-wheel drive and 2 wheel abs with about 230000 miles on it.
I Recently replaced my unit bearing on my drivers side because I thought it was the cause of a grinding that only happens on hard left turns but I wasnt the cause it was going bad causing play in the half shaft. I didnt seem to notice and wear on the shaft from bad needle bearings but I have to take it all apart again to be sure. Was just wondering what else could be the cause of this noise. I plan to pull the axel shaft and change all the seals.

I just replaced the passenger wheel hub assembly (and axle due to complications) and the noise is still there. I have a loud hum that starts at about 30mph, is present when going straight, but gets much louder as the steering wheel is turned to the left. It is completely gone when turning to the right. It gets louder with speed and how much the wheel is turned left. At highway speeds, on a long sweeping left-hand curving connector, the noise is VERY LOUD. There is a slight vibration that occurs, but it's not bad at all. The noise continues when the trans is in neutral. I've even shut off the car while testing this in a parking lot, and the noise continues. The noise varies depending on the height or load of the suspension. It varies as the car rides over dips in the road.
I really though it would end up being the passenger wheel hub, even though there was no noticeable play in either hub. I've had noisy hubs before that had no noticeable play. But after a very obnoxious repair, it's not the hub. All tie rods have no play. All 4 heels were recently aligned. The alignment made no difference in the noise. I replaced a bad tranny mount about a year ago. Motor mounts look good. Ball joints are good. Replaced axles about 3 years ago. Replaced bad struts and strut mounts about a year ago. New control arms due to bad bushings. All these things I've replaced recently were making noises too, but the left-hand hum is always present. This is my last noise and it's driving me crazy. I've always felt it comes more from the driver's side, but my wife disagrees and my hearing isn't great due to too much range time.
Oh, I recently noticed that the steering wheel tends to want to return to center from the right more than it does from the left. Again, alignment was done by a reputable garage just a few months ago. They also found nothing during there safety inspection. I also noticed that the car is not sitting level as it seems that the rear driver-side spring is sagging about 1.5". The noise is not very obvious from outside the car. I know I'm forgetting some other things I've checked for this problem. I'll post more as I think of it.
My current theories are driver's-side hub, something with the steering rack, spring heights, something vibrating (body panel, loose part?), something with the auto-tranny.

I have a 04 explorer limited awd and I get bad vibration when i come to a stop and turning left or right but it don't do it when I stop and drive straight, I feel it in the drive train, what's wrong?

I have a 2000 f250 crew cab short bed 7.3 on a 6inch bds lift and 37 inch tires. When I accelerate pretty much any load above 1200 rpms I can feel a vibration, kinda feels like it may be coming from the front left but I'm not sure. I have heard that a wheel bearing going out can cause this, would this maybe be what's causing it?
I thought wheel bearing because it kind of sounds like there's a howl when decelerating, probably when accelerating as well but the trucks too loud and I can't hear it. or also have heard motor mount gone bad, I've also heard ujoints but the ujoints were done this summer. the front ujoint is bad but the front driveshaft shouldn't be turning when out of 4x4 and hubs unlocked.

I ran about 500 miles today loaded up pretty good and noticed every bump I hit that was enough to rock the truck and trailer that there was a noise I've never heard before. It was like the difference between asphalt and concrete road surfaces, but was only present when the springs were sufficiently compressed. Temps were between -10 when I left to 10 or so above when I was destinated. Would that cause the noise?

I have a 2010 Explorer XLT that I bought in 8/2012 with 7,000 miles on it. I had had a problem with a groaning noise and slight vibration starting at 34 mph, under load. I don't hear the noise if I let off the gas at 34. I hear it a little past 35 or so and it doesn't seem to groan again until about 60 mph or so. I also have a feeling of the all wheel drive engaging when I back out of the driveway, put it in drive and turn the wheel slightly.
I took it to the dealer this week under warranty and he calls me today and says the tires are worn differently all around and that is causing the problem. He says the tires could be out as much as, or as little as 1/16 of an inch and that is what is causing the all wheel drive to catch and also the groaning noise. I understand what he is saying, but I can't believe that is the problem or more would have been written about it.
I asked the guys about rotating the tires and he said it would not matter, it would just take the problem from one end of the vehicle to the other. These tires are not worn like the truck is out of alignment, it is just normal wear. It now has about 21k on the odometer. What do you all think of this diagnoses? The guy says the PTU thinks it needs the all wheel drive and therefore engages it. This truck can also be manually put in 4 wheel drive by flipping the switch.

I have a 2002 Accent that has recently started to sway side to side when I'm turning left. It almost feels like the back end is swaying but it's hard to tell. I've recently had the CV Boots replaced as they were torn but I don't think that's related at all.
I'm wondering if it could be the suspension. I've looked at all the wheel housing and checked the steering rod for any play but everything seems fine. If it could be the suspension how would I go about checking it.

155k miles ... Just started last night. Coming into a left turn with brakes, the ABS engages (buzzes and I can feel it in the pedal). doesn't do it when braking straight or braking and turning right.
Left front wheel bearing (and ABS sensor) was replaced 2.5 years ago. Right one never done.

My rearmost drive shaft u-joint is bad and has slop. I've been having vibration for about 7-8 months, but just started hearing a noise within the past week, especially when taking off with a load on the drive line (uphill or heavy acceleration). The vibration has not gotten worse, just that the noise has just begun to show itself.
I have one u-joint which is OE and has 275K miles on it, and it seems to be OK at the moment. The other two (including the rearmost unit) both have about 100K miles, as does the center support bearing.
Just because I don't want to worry about anything, I'm going to replace all three u-joints with Moog Super Strength units, and will also replace the Center Bearing with a new Spicer unit... just because I can and don't want to be pecked to death with multiple failures in the same drive line. I ordered the Moog joints because the only Spicer joints I could find were for the 4wd configuration.
That's the context... here's my question... The parts are on order and won't get here for several days. I've been driving the truck like it is at about 1500 miles monthly. Do I continue to drive the truck for another week before getting the joints and bearing installed? I know it's a guess... just looking for more perspective.

I have a 2000 F-350,7.3, 6 speed. Just the other day I made a turn and my passenger got her feet wet. It had been raining and I also had the ac on. A couple of days later the same thing happened, but it had not rained, just the ac on. What is causing this. I do see condensate discharging under the truck.

99 Intrigue 3.5 with 200,000 miles has severe front end vibration on initial aggresive start from a stop. Worse when wheels are turned. Doesn't matter if turned to right or left. Drives fine on highway, no problem for straight line or easy acceleration from stop. CV joints original, boots good, car has been trouble free.....

Just had a new issue pop up - sometimes, when making a sharp left turn when the engine RPM is low (going into driveway, turning at a stop sign), the engine will suddenly die. It seems to be running fine otherwise, it does not idle rough, and the idle RPM is around 600-700. It never dies on the highway or higher speeds, yet anyway.
I do notice that my power steering pump is making a little noise. It is an aftermarket pump. The steering assist seems to work fine though.
I recently had the spark plugs, valve cover gasket, and a fuel pressure sensor replaced. As I understand it, the mechanics checked the fuel pump and it was working fine.

1998 olds intrigue, 3800, auto, 4 wheel disc. Spongy breaks (ABS/Trac/Check engine/service engine soon). Friend brought her 'new' car over the weekend complaining about breaks feeling spongy.
First looked at the car and noticed the driver front passenger rear rotors had a lot of rust. They were also cool to the touch, odd after a 20 mile trip. The driver rear speed sensor has been repaired, and was unplugged.
The breaks are not working on the passenger rear, driver left. There is not any pressure at all at the calipers, and the rusty rotors show this.
Put the car on jack stands and with breaks depressed, the driver front/passenger rear wheels spun freely.
checked break lines/fluid, no obvious leaks.
I tried bleeding from the valve assembly attached to the master cylinder, and got only fluid out of the one bleeder, but not the other one. Could this be the master cylinder causing this, or the other assembly?
[URL]...
The bleeder on the right had nothing, the bleeder on the left that had fluid/pressure.

A while back as I was driving, I heard some sort of clunk, and the steering wheel locked and would not turn left. It then unlocked after a few seconds. Ever since then, it has been very hard to turn to the left (and right, at slow speeds and on sharp turns, but much easier than turning left). This happened a few days after I replaced both front end struts and inner tie rod ends, and got an alignment - they were cheap quick struts (entire assembly), but seem to be of fairly good quality.
Initially after some consultation I thought it was the power steering pump, so I replaced that. It became easier to turn right, but still very hard to turn left. I took the front end off the ground and turned the wheel all the way left and right, no problem or resistance. I am nearly certain it is not the pump.
At this point, I am fairly certain it is either the steering gear or some part of the rack and pinion. I am planning on getting the assembly replaced. The fastest and cheapest way is apparently to just buy the entire steering gear/r&p assembly. Would bad strut mounts ever cause an issue like this? Any other possibilities besides the steering linkage?

I have an engine noise on my 2000 Dodge Caravan with the 3.3 engine. It sounds a lot like the grinding of a rotating part. It occurs at start up, momentarily, then goes away. If I drop it in gear and start doing low speed maneuvering in the driveway, it comes back. If I turn on the AC it comes back. In all cases, the noise goes away at around 1200 rpm.
The noise occurs again, when I shut the engine down.The engine performs and runs smooth and normal otherwise. No stalling, stumbling, or bad gas mileage to report.
I can "feel" the noise with my hand, when I put my hand on the ac compressor bracket, or the intake manifold, or the valve cover. I've tried the listening through the stick method, and it seems to be coming from the front area of the engine. But I can't be sure. It is something internal. Let me describe:
I thought it was my AC compressor or clutch going bad. The fact that my AC had stopped working well, and was making jet engine noises at high rpm supported me decide this. I replaced the compressor. The AC works great now, and the jet engine noises went away. But the grinding noise is still there. As described.
I wishfully thought it was the belt tensioner or idler pulley. I replaced both of those. Noise still was there. I pulled off the serpentine belt, and started the engine. It made the noise, very briefly as it started, then went away completely. It made the noise again briefly as I shut the motor off. So it's still there without any of the accessories turning.
The noise is loud and obnoxious at idle when under load. It just can't be good. I've read theories about similar sounding problems, saying they could be loose timing chain, bad oil pump, slapping pistons, crank journals, flexplate/flywheels cracked.
I'm going to try doing an oil system flush, and then I'll change it out with a little thicker oil. See if that makes any difference in the noise. Currently I'm running 5w-30 Mobile 1. I think. I'll let you know if it changes anything. I'm also thinking I want to make a short video of the car idling and making the noise for my video camera. I'll post that on youtube and link it here.

There is a slight noise when turning left sometimes, its not to major, but out of curiosity I went to the mechanic and was they told me this needs replacing:
R& R AXLE SHAFT & CV JOINT - $195.00
R&R STABILIZER LINK BUSHING - $59.50
That was the labor, they did not have the part piece prices since they have to order them.

I'm getting a weird grinding noise when turning left/right. Doesn't happen with normal turns, just at the sharp extremes. What might cause it?
