Ford - Aviator :: 2003 - Shaking And Vibration At Most Speeds
Apr 28, 2015
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'm four weeks into my 2010 LX570. From first day, I've had vibration/shaking at all speeds--the shaking/vibration is not in the steering wheel like a few others have described. The vibration/shaking is similar to what one experiences going over a railroad track in a small/lightweight vehicle, except it happens on all types of roads and at all speeds.
Two trips to two different tire installers and one trip to Toyota (the closest Lexus dealer is a couple hours for me) to speak with their Lexus-certified mechanic and it was chalked up to the Dunlop tires. The Dunlops had excessive road force (three were between 28 and 45). Three separate sessions with Lexus Customer Relations, and nearly two weeks with Lexus of Orlando (they were extraordinary, even though I did not purchase from them), all four tires were replaced with Michelins, road force balanced to less than 8 each, and the vehicle extensively tested. They bent over backwards and were exceptional. While the problem has been minimized, I still feel the vibration/shake.
I'm coming out of years with several Range Rovers, but every other vehicle I have does not vibrate/shake, from my Tundra on up. I just spent two weeks in an ES300 and it was rock solid, at half the weight and half the cost. Additionally, none of my Land Cruisers (previous generation to the current) were anything like this. The LX is a great vehicle, but the vibration/shake is a real issue.

I've had my IS 250 F-Sport for exactly 6 months now, and over the last month I've noticed that when I'm pulling in to park or backing out (at a very low speed) with my steering wheel turned right or left from the center, I hear and feel some shaking/vibration from the car. I can't pinpoint if it only happens with the A/C on.
I live about 3 hrs away from my Lexus dealer now, and my first maintenance appointment is at the end of the month. I'm pretty disturbed. I have about 4500 miles on the car.

I have a 2003 Nissan maxima and at first it used to shake at around 50mph, took it to the shop they looked into the suspension, did wheel balance, changed 2 front tires and wheel alignment and they said it should be fixed. A week later, it started shacking at around 70 mph, what else should I do to get ride of this problem?

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 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 '03 F350 that I can't seem to solve the brakes vibrating when applied. Replaced front rotors a couple weeks ago. I still have a vibration when I apply the brakes. What am I missing? I didn't replace the back rotors, but maybe I should have. On the passenger front, the inside pad was almost gone and the outside pad was in good shape. I greased the pins before I replaced the pads the last time, but the inside still wore much faster. I also blew out the rear brake line last week and spent Saturday bending a new line and replacing that so the brakes were bled when I had to replace that. I don't feel the pulsing in the pedal, but the truck shakes pretty good when I hit the brakes. What else should I be checking if the rotors are new and the pads are new and the pins have been lubed and the brakes have been bled?

I have a 2003 Lincoln aviator with the 4.6 V-8. When I was seafoaming the car today, afterwards I noticed the truck running a bit rougher, and the truck idles around 500-600 rpms instead of 900-1200 rpms. There was a hose connected to the left valve cover, I pulled it off and there was no change in power or sound or idle. Is the hose a pcv hose, if so, where is the valve on this engine in the aviator, shouldn't it be on the valve cover? Do you think its a vacuum leak cause by the pcv valve/hose or a vacuum leak somewhere else? does aviator 4,6 come with a valve or just a pcv hose?

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 ....

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.

Looking for the location of purge valve on a 2003 aviator ?

I'm a mechanic but work only on cars so I'm a little shy on diagnosing trucks. I have a 2001 7.3 f250 4x4 short bed, when I give it gas I can hear a clunk, when I let off of the gas I also hear a clunk. Also when traveling at high way speeds I can feel a strong vibration when I very lightly give it gas but the vibration goes away as I give it more gas.

I have an '03 Aviator that has this really odd stumble / shutter while driving down the road. It loses power and feels like it is going to stall. This is very intermittent and not obvious at idle. Sometimes on hills, sometimes just cruising along. I did some reading and thought maybe I had an ignition coil(s) going bad.
I took the covers off the coils and pulled them out. Six of them looked perfect with one being newly replaced by Ford. Two of them had a thin film of oil mist on them both outside on the rubber boot and inside the rubber boot. I wiped them off and put them back in. There was no oil down in the plug bores and the valve cover gasket looked good. The plugs looked good too.
Is there any way to actually test these? If the problem is intermittent I am not sure if they would fail a test until they got hot from use. I do not have any lights or codes.

I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?

My 03 Tacoma TRD is showing her years! The truck has about 215k and has some serious vibrations and noises going on. First off I have a constant shaking type of vibration between 25 and 35 mph, but it is also present in the higher speeds of 55 and above but sometimes it gets drowned out. I work at a ski resort so when Im coming down the mtn using 3rd gear or so to slow down I feel the vibration is the most apparent then. So far I have had 2 shops look at my driveshaft and both concluded there is nothing wrong with the u joints. I had a CV shaft installed because one of the boots was torn so I went ahead and had that replaced.
What the vibration is.....2nd is more of a intervalled whooomping sound almost like a bullfrog-like interval. As I increase speed the intervals get faster but it is a drawn out whooomp whooomp not a fast sound. It actually rattles the change in my ash tray to the bpms of the sound. Also I have a metallic clunking sound happening when I put the truck in gear (manual) or start and stop at slow speeds without using the clutch. I was driving around a parking deck the other day in first gear and it would make the sound whenever i hit the gas AND when I let off the gas. ONE MORE THING, whenever I am starting off under load in any gear, the truck jerks.....it hesitates and lurches but only at low rpms and again in any gear.

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 2003 Aviator kind of stutters when in auto between gears. Most prevalent from 3 to D when driving regular. If I shift manually and tach it to 4k there is no stutter/vibration. My engine light is on and pretty sure the catalytic converter need to be changed. All new NKG plugs and associated coils. Throttle body clean, 91+ fuel only. Could this me a tranny starting to fail or computer/senor related? No other codes than the bank-2 O2 sensor....

I have a 4-cyl 2003 Camry LE with a bit of a vibration issue, but first, some backstory.
I put in new tires about 20,000 miles back and I started to notice a pull to the left side and no amount f alignment would fix it and there was no other discernible issue with the front end.
I read about how some tires have some internal issues with the radial belts and I decided to rotate the tires. No more pull. It didn't change the fact that the tire may be defective and still causing issues.
Could a tire that caused a strong pull on the front end cause a vibration at high speeds in the rear?

I have a 2003 Buick Century in automatic with overdrive. During the past week I experienced a hum and slight vibration at speeds over 20 mph. (The faster I drive the higher the hum.) I checked the transmission fluid. It was brown and pink but did not smell burned. I have not changed the trans fluid in 2 years. I sent it to my transmission guy for an oil change. He said that the 1st gear clutch was having some problem and there was no 4th gear. He suggested another transmission...
