Ford Excursion :: 2003 - Vibration When Braking In OD At Higher Speeds
Apr 29, 2014
2003 7.3 Excursion, 130k, stock suspension with newer bushings, etc.
Vibration when braking at higher speeds - not felt as pulses through brake pedal or shimmy through steering wheel - rather, a "body" vibration. Stops as soon as the TC unlocks. Being a diesel I can't tap the brake to allow it to unlock like on the gasser 4R100's - its locked until it shifts down into 3rd. Turning off OD puts it into 3rd but locks TC (no way to "single out" TC). Only felt when braking in OD (though I haven't tried running up to highway speeds with OD off/trans in 3rd) - braking is completely smooth at all other times/gears/speeds and at all braking force (light, mod, heavy).
Front and rear pads are good with even wear and sufficient material, lugs evenly torqued, tires good/balanced, no sign of a stuck caliper or rotor warping, MM manual hubs unlocked. No driveshaft carrier on the Ex's, just a regular two joint shaft with recent Neapco Gold u-joints, no slip yoke play. Trans filter replaced 4k miles ago, 6 +/- qts DexIII/Merc exchanged when I did the filter, fluid smelt and looked fine. Transfer case fluid changed about 5k miles ago. Factory LSD rear diff not serviced recently but fluid suctioned from fill hole looks acceptable.
I'm afraid that something is going on with torque converter/shudder but I don't get any shudder or slip under acceleration or at any other time and gear shifts are smooth. I know that the 4R100's can be sketchy, especially with 130k, but want to get suggestions before digging into it. I've also got a very slow hydroboost leak/weep but the power steering fluid is properly filled. Steering is smooth and proper, brake pedal movement is normal so I assume there is no air in the lines.

I have two simultaneous problems with my 2005 Elantra (automatic transmission). I don't know if the problems are related or not, or if they are alarming or not.
Background on the car: timing belt and water pump replaced in 2010; four tires new in 2010; oil changes every 5000 km.
The first is that my engine is making this 'whirring' sound when I approach 80km/hr. It's not high-pitched, but more of a droning noise. Having read around the forums, I see that Elantras commonly make funny engine noise, but this is fairly new to my car (145,000 kms) and definitely not there at all when idling or at low, city-street speeds.
Additionally, I have a weird vibrating noise coming from the front left of the car only when I am dead stopped and the brakes are fully depressed. It doesn't make this sound in park, and I don't hear it until the car has come to a complete stop; there is no odd noise while slowing down.

My 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.

My 2006 3.6 awd has developed a propensity to roughly downshift when braking at higher speeds particularly on inclines. The VW shop cannot replicate the problem, but a tech is driving the car for a few days. What might be the cause of this?

I change my own pads as a good lifetime warranty with free replacement from Autozone is great!
But with the Tribeca... I changed the front rotors just like all my other cars over the years.. and now there is pretty severe pulsation when trying to brake... I've checked the rotors and pad replacement twice now and all looks perfect.
I searched this pulsation issue and saw on a Jaquar site that you can ruin the ABS on some cars when you don't drain excess fluid as you push the piston back to install then new thicker pads..
Is this an issue for B9? I don't see it anywhere... I'm ready to bring it in the shop.. the pulsation ONLY happens when braking and gets more severe when stopping from progressively higher speeds...

I have noticed recently that I seem to be getting less regen braking force than I used to. Particularly noticeable at higher speeds at over 45MPH or 70 KMPH. The regen seems to have very little effect now until I have slowed down. I seem to have to use much more brake than I remember recently. And by the way the battery in not nearly fully charged....Regen does come on but seems to have very little slowing power....

Recently when I was on a longer distance drive (multiple hours) my car was producing an unusual vibration. It seemed to go away after some time. At the end of my drive I was turning left around a bend and there was knocking sound. One of the boots on the cv joint has been leaking grease so I went ahead and replaced both cv axels.
The knocking is still there. Here are the symptoms:
- Knocking sound when turning left when the accelerator is down.
- Knocking sound is somewhat intermittent when turning, not always continuous.
- The vibration is not always there and is only there at higher speeds, and is made worse when accelerating.
- All of this appears to get worse the longer the car is driven (heat?).

Ok so we all know it's usually warped rotors or possibly a caliber problem. But let's say u have new of both. And still I'm getting a wobble, not only when I brake at higher speeds, but when I'm on certain roads. Only certain roads. Say about 20% of other roads while driving I get a slight wobble. Not too bad, but a very annoying wobble. I bought this CTS at 35k and now has 45k on it. And again I bought this car for my long commute and a smooth drive. Which I'm not getting. I can't take it anymore! I've got to figure this out. Getting a wobble in the steering while on super smooth roads. And I know it's the car because I have a Chevy Cavalier and a Dodge truck in the family that don't wobble on the same roads.

Noticing excessive vibration when braking after 50-60 mph speeds.

My wife has an Acura, and when braking at higher speeds, she is getting a really bad "vibration". I am assuming the rotors are warped. We had both axles (rotors/pads) done last year (about 40k ago) at Midas. After they did them, we had to take the car back about 3 times for squeaky pads, and I swear a slight vibration, but they didn't fix them. Anyway, even though they offer "lifetime pads," I refuse to go back there.
So, her pads now started squeaking again. We were dealing with the warped rotors until we had some extra money and time to take it in. At this point, I am wondering where I should take it. I have no clue if the pads are good, and I'm guessing the rotors just need to be turned since they were just put on last brake job.

I recently purchased the rims from another member here on Club Lexus.
Ever since installation, I have been experiencing a vibration at highway speeds and while braking. The wheels are correctly balanced.
My technician has told me that I need to buy a hub ring/spacer (not too sure what that is) but nonetheless, a grommet of such that fits between the backside of the rim and the frontside of the hub. I'm not too sure where to begin from there or what to even look for.

I have a 2007 dodge Dakota with 112K miles. At 105K I had the front brake rotors and pads replaced. The rear brakes were fine. There was a problem with one of the rotors and I returned a week or two later and one, which was warped, was replaced. Ever since that second visit I have had an intermittent vibration from the vehicle. When I brake the whole truck vibrates. And by vibrating, I mean some pretty heavy shaking. It is not the steering wheel vibrating. I took this back to the mechanic where they were unable to find any issues with the brakes. Also, we could not (of course) re-create the issue while it was in the shop. I have not been able to find the pattern. It happens when I am braking at high speeds, but not every time. It also happens at lower speed, but again, not every time.

I replaced my tires yesterday with Bridgestone Turanza ER33 (245/45/19).
After replacing the tires, there is is an extreme vibration in the front end of the car when braking at highway speeds (60+ mph). Braking at sub 50mph speeds is completely normal. No lights, no vibration while driving. What could be the reason?
Also while removing the lug nut locks, the locks key broke apart (the black piece came out of the key). After like 45mins of trying, finally we got the locks out. I threw them away.
I searched online for regular lug nuts, but couldn't find any beside ebay. The local dealer says I need to wait for 3 weeks to get them from Japan! Where can I get a set of 4 regular lug nuts online?
I'm now running on 4 lug nuts on each wheel. Could this cause a problem? Could the vibration be caused by not having a 5th lug nut in place?

I have a 2009 Chevy Malibu that gives through rotors every 6 months. I have replaced them 3 times now in 102,000 miles and had them turned multiple times. What happens is about 6,000 miles after I put new rotors on they warp and I get a violent vibration when braking at high speeds. I have been to 3 different dealerships and none of them can figure out why they continue to warp.

I have a 2004 Honda Accord EX (4 cyl) with 102k miles. I bought it brand new and kept it completely in shape with regular service. For the past few months I start getting front end vibration at braking, mostly when slowing from high speeds and without any repair this vibration has now became common at all speed.... my diagnosis - I need to replace to turn disk/rotors....
While I have not remedy the rotor issue yet, I started getting this new vibration at 60 to 80 mph.... Below and above this range of speed i have no vibrations - the car will drive fine. This type of vibration in my experience for front wheel drives is mostly due to balancing or bad tires. so i took the easy way ..... and as i already needed tires well i dished out the dough and replaced all four with Michelin Primacy hoping that it will resolve the speed related vibration.... Well it did not?
I continue to drive as-is without addressing the real problem - coz I'm not sure what is causing the vibration.... now new additional vibration started on acceleration; any time I hit the gas pedal (normal acceleration or kick-down) I get vibration very similar to when a stick shift's gearbox required replacement/repair of the worn out pressure plate's (fingers/springs gets bent or weak) or the thrust bearing needs replacements/repair/grease packing. I'm from the old school stickshift transmission, my knowledge in automatic is very little - I have repaired Acura's automatic transmission before but I don't think repairing once will make me an expert in automatic.
So to summarize my issues or current state:
Issue# 1 front end vibration on braking
Issue# 2 front end vibration 60 to 80 mph speed only
Issue# 3 front end vibration on acceleration at all speed
The list above is in sequential order as I have experienced.

I have a 2000 Excursion 7.3, 6 position tune, and exhaust as far as mods (on truck when bought). Last couple of weeks I get no power while on the throttle, foot on the gas and the whole truck shakes at higher speeds - 40mph and above. At first it wouldn't go above 60 or so, would hit the gas and Rpms would just stop not be able to generate any further power. Changed the IPR, ICP, and CPS.
I still get the high/low range ICP codes, P1280, P1281. First night the IPR was changed I got it up to 90mph and thought it was all solved but got a little shake right at the top and I let off the gas. Next day back to square one and has seemed to get progressively worse, almost wasn't able to make it up a hill by my house not even going 20mph, but it's like intermittent. I have a scan tool, here is at idle and at around 60mph ....

So my car (2001 Civic) was having some issues that I needed to get worked out, so I was driving my mother's car for a few days. Within the first few minutes I knew there was something wrong, but I had so much going on that I haven't had a chance to get back to it for a while.
So she has a 2003 Toyota Camry with just 39k miles. Her work is about 2 miles away from home, so it basically gets driven there and to get groceries, and local clothes shopping. The car basically never sees the highway.
Hard to describe the sound, but it's like a loud rattling/vibration with every revolution of the front wheels. It sounds like it's coming from the front passenger side. Either the tire or the engine area. Here's a video of it on youtube. You can hear it pretty clearly under the road noise. It sounds kinda of like going over train tracks or something, and I'm only going about 45mph in the video. [URL] ....
So I don't know much about the car, but I am very familiar with my civic, so I checked out a few things. The tires appear to be in pretty good shape. About half the tread left with no unusual wear. I doubt it's the tires, cuz it really doesn't sound like tire noise. I checked the engine mounts and they appear to be in good order without cracks. Wouldn't expect an engine mount to go at 39k miles either, regardless of age. The car is garage kept.
Neither wheel has any side to side or up and down play like a bad ball joint, tie rod end, or wheel bearing would have. The steering wheel doesn't vibrate or anything. The sway bar endlinks appeared to be in good shape. I just changed the brake pads and rotors because of an unrelated issue. It didn't fix the problem.
A couple of things I will note: The belts are kind of dirty. It was really weird because half the belt is brown, the other half is black. It's basically split down the middle of one side. It's just dirt though, as I was able to rub some of it off with my fingers. The car was in a minor accident a couple of years back. It required me to replace the bumper and the passenger side headlight.

I have an 03 Aviator with the full-time AWD with about 138,000 miles on the odometer. The truck is reliable and I love it, but I keep noticing a shake and vibration going on, I notice it at almost any speed, I'm pretty sure it gets worse at high speeds and when braking ( especially at high speeds). would this be a transmission problem, a bad cv or u joint? or would it be bad tires or wheel bearings? shocks/struts, rotors?

I recently bought a 2003 F150 sport Scab 4x4 with 75k miles from a Ford dealer with a 4.6l auto. we didn't notice it when we test drove it but it has a squeak when going 0-10 mph in forward or reverse. The story goes a week after getting it home we started noticing a vibration and thudding in the rear end when braking so I take it back to the dealer (50 mile trip 1 way) and when I get there the drivers side rear rim is 30 degrees hotter than the passengers so the tear it apart and find the e-brake was dragging so they lube it up and tell me its good to go. I made it around the building and now I feel it dragging iddling around the parking lot and it is still squeaking so I take it right back in.
Long story short after going through this 2 times that day and bringing it back another day they replaced rear pads, calipers, roters and the hoses going to the caliper and tell me its good to go. Well it no longer had the dragging feel and I had to drive through DC traffic so I beat feet for home and on the way noticed its still sqeaking. I call them and they tell me to put a thousand miles on it and maybe the pads just need to wear in (??). so I took a road trip and 1.2k miles later it still squeaks.
I have tried to tell them it may be the u joints (after searching on here I learned that I am taking it back tomorrow and going to try and get something done but they are still saying its something to do with the brakes and probably won't do the u-joints. Normally, they are filling up the gas tank every trip up there and its all been under warranty (gonna see about getting the warrenty extended tomorrow due to this problem has been ongoing since we got it). Should I just let them run their own course and keep making trips back and forth?

I purchased a 2003 F-150 Screw a few months back. Within a week I noticed a noise that sounded like a bad ujoint. To it to a shop and they confirmed it. They told me they replaced both. I only drive about 4 miles to work around 40 mph. Friday I had to go out of town and this was the trucks 1st road trip. I noticed that around 55 the truck feels fine. At 65 there is a shake / vibration. At 75 it is very noticeable. At 1st I though front end, but after a few hour I noticed the feeling can be felt in the seat of my pants type of thing. Or my foot on the kicker panel. Truck has 27K on it.

I have a 2000 with a six speed and through the first 2 gears while giving it only a little throttle, worse on hills and worse while towing I have a pretty decent vibration. Once you get to 3rd and up its fine. I have read about axle wrap and due to the fact my springs are pretty wore out I think this is a big part of it. Any other things to look at other than new springs? The u joints all look and feel fine so I haven't touched them.
