Ford Excursion :: Loud Clunk / Thump Sound Coming From Rear Of Vehicle
Apr 6, 2011
Our excursion usually sits unless we are towing or need to haul a group of people. The past three days my wife has been using it as a commuter. Yesterday she told me that two times at start-up she has heard a loud clunk/thump sound coming from the rear of the vehicle. At first she thought it was happening when she engaged the brake to put it in drive. Today she called me and told me the sound came just after start-up while the vehicle was warming up before the brake was applied. What this could be? I wish I would have observed it so I could give more details.

I was running a small errand today, about 10 miles round trip. When I started out, I heard a small 'clunk' sound coming from the rearend. When I was on the return trip and making my last stop, the 'clunk' sound had become quite louder as I accelerated, and could really feel it. When I got home, I took a look and was expecting to see maybe a sway bar link detached or the bushing worn.
I did not expect to see two lug nuts completely gone, including the stud, as well as the holes in the rim no longer round. Big gouges in the rim around the remaining lug nuts, about to be sheared off! The other side had two missing lug nuts, however, the rim is still intact. What would cause such horrific damage? I am lucky that I was not driving on the freeway at 80 mph! This is my 2002 Excursion 4x4.

Went for a drive last night in my "new" 2002, 4wd and which brought up some newbe excursion owner questions. First of all it has 95,000 miles on it and it is a V10. I noticed a clunk sound from the back of vehicle intermittently. u joints?, rear springs? or rear end?
Noticed that the front springs looked like they were sagging, is this normal or do I have an excuse to lift it? Also the shocks appear to be the original units and I figure that they are going to be on their way out. In the past I had good results with KYB gas-a just on a old F250 2wd.

The other day, I was coming home from work. After dropping off co worker, an old man pulled out infront of me. I applied the brakes. As car came to stop I heard a loud thump come from rear. Sounded like i was either bumped by a car, or maybe my entire rear end slid up 5 inches. But that's kinda what it was like. Then after the thump, I put my foot on gas pedal, and instead of car moving forward, the engine just revved. No movement, revved to like 3 grand. I let foot off gas pedal. And tried again. Car moved as normal. Then on the way home i attempted the same combo of rather quick brake and then gas. Same kinda thing happened. Not so hard of a thump. But noise from rear followed by the car no moving, just revving up till i stop and then try again. So even tho my story may suck n my explanation my suck more, whats going on? I just picked this wagon up. 01 glx 65k.

I did a search and most of what I found is about front end/middle body flex, not rear end "clunk" noises.
Bushings?
I'm already planning on replacing all four shocks.

My boyfriend bought a 1999 ford explorer, he put about 2,000 miles on it in four months... I believe it now has roughly 110,000... Now the other day, he was pulling out and shifted from reverse to drive, we heard like a loud clunk/thump noise... It shifts into drive, and revs but won't move, it feels like neutral... If you shift to second, first, or reverse it's fine... Tranny fluid is good... O/D is always engaged...

I have a noise that has been driving me crazy for a week now. After some investigation I have discounted a few things. To sum up the noise, it seems to be coming from under the vehicle, maybe the passenger rear. It sounds kinda like a jack hammer and it is loud. People on the street can hear it well! There is no consistency in it. I do not here it standing still and it only appears when I am driving. The speed does not matter.
While driving, it will come and go, it will last from 5 seconds to up to 30 seconds. While driving along, it starts, then stops abruptly without dying down. The speed of the "knocking" will follow the speed of the vehicle. If Im going slow (20 mph) it will knock at a slower pace, thus going 65, it is 2 a second. There is nothing loose, I have ruled that out.
Although it does sound like something loose and hitting. I can feel it slightly on the floorboard under the pedals and passenger side. I have to believe it is the rear u-joint? but that was replaced 2 years ago, and I have never heard of a u-joint making this noise.

I have a 2002 Santa Fe that has started to have a very loud rattle. It sounds like it is coming from underneath the vehicle toward the rear, possibly the passenger-side wheel-well, but that specific location just may be an auditory illusion.

I had a pretty good clunk going on and found the passenger tie rod was shot. The rest of the steer components looked fine. Fixed it and still get a nice bunch of clunks. Went over the steering again with someone rotating the wheel and didn't notice any crazy movements. The drag link twisted a bit but the joints looked solid compared to the tie rod which was completely shot.
So I decided to dig into it today. Looked again and nothing. So I took it into my back yard to drive over some humps left from stump grinding. Clunk, clunk, clunk. I stuck my head out the window and wouldn't you know it the sound seems to be coming from the rear! Took a pry bar to parts like the sway bar links, shocks, etc.... can't detect anything. Maybe a u-joint? Gotta dig in I guess.
Also my rear springs creak like nothing I've ever heard. Dirt roads it's just creak, creak, creak.

1996 Nissan Sentra GXE, 147,000 miles. Automatic transmission. When I start moving after starting the car, I hear an ominously loud single clunk coming from the area around the right rear wheel. I start the engine, no clunk. I release the parking brake, no clunk. I put the car into gear, no clunk. I take my foot off the brake and begin to move, CLUNK! And that's the last I hear of it while I'm driving. There are no rattles, shakes, or other problems as I am driving. I can stop for a traffic light, and there's no clunk when I start moving again. Shift into reverse, and there's no clunk. Hit a pothole, nothing.
It may be worth mentioning that I have a huge hole in the right side of my muffler (seriously - I can stick a few fingers into it) which I am not going to repair. And that is because in five weeks I am going to be buying a new car. I've arranged time off from work to do all the running around from bank to dealer to insurance agent to DMV, and I'll have enough cash at the ready for a large down payment. So I am very reluctant to have any work done on this car. So what it comes down to is can I 'baby' the Sentra as much as possible and use it as little as possible over the next few weeks, or am I in danger of losing a wheel (or something) at any moment?

I have a Ford Explorer that my mechanic says needs a new trany. The vehicle takes a while to engage in reverse and does so with a loud clunk. Otherwise it runs good. I have 198K mi. It's an "02 4wd. Their asking $2,100 for the rebuilt trans. Wondering if it's worth it? May have reached the end of the line on this vehicle?

2003 Saturn Vue V. 61,000 miles. Drives ,steers and turns normally except when you do a very tight 360 circle. Tremendous grinding sound and shuddering coming from the rear of the vehicle. Return to driving a straight line and everything returns to normal. What is the issue and what would it cost to repair?

For the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?

A couple of weeks ago I heard what sounded like a loose heat shield, coming from under the Ex. It went away, but then came back a few days ago. I got underneath and looked at all the welds on heat shields and for anything that seemed loose, I found nothing. Yesterday it started sounding like a card in bicycle spokes, coming from the right rear. This afternoon I pulled the wheel off along with the brake caliper and disc. What I found was that one of the springs on the parking brake shoes had broke and has been ground up in the drum. I didn't take any pictures, but thought if others hear that sound it's something you may want to check.

I have a clunking sound coming from the rear of my X when I stop and take off. The sound does not happen until the vehicle has been driven for a few miles. After it has been driven, I will get one clunk when I stop. When I take off I will get one clunk as the vehicle starts to accelerate, and another clunk as I give it a little more gas. What could be the cause of this? I do not get the sound when I shift from park to drive, or drive to reverse.

Purchased an 09 Touring and so far enjoying the driving experience. Getting 42/43MPG with mostly short trips. However, I have noticed one thing unusual. Not sure if I should be concerned or if this is a normal thing. I am a rideshare driver, and whenever a group of people get out and I accelerate away from them, I hear a pretty loud thump sound. This happens usually when a group of 3 or more exits and often does not happen when one or two people exit the vehicle.

I just picked up a used 2009 LS 460 AWD last week with 45K miles. I have put about 1000 miles on it so far myself.
When I hit any small depression in the road at 10-45 mph I hear a thump in the rear. The bigger the depression and the more weight in the backseat, the louder the thump noise and even an occasional bottoming out feeling occurs. It hasn't happened at highway speeds so far.
The bottoming out feel occurs only with a medium to large depression. I am not talking about a pot hole, just pavement depressions where two sections are not of equal height or you are transitioning from a primary road to a side street and the is a depression to allow for water run off, etc.
If I have someone sitting in the passenger seat and the backseat and accelerate quickly from a dead stop, I get a similar rear thump and even a bottoming out feel. This occasionally occurs even without a without a depression in the road. With no one in the back seat it does not do it unless there is a big depression in the road.
Finally, when cornering on a 270 degree off ramp at 40 to 50 MPH the rear end will start to hop and bounce. If I slow down to 15-20 mph it goes away. Still, it is irritating and embarrassing. I have tried all comfort settings and get the same results.

I've been having the loud clunk under the drivers side floor, that many others have as well. Did many hours of research and replaced the sway bar end links. Napa only had the left side in stock so I did it first last weekend and did the right side this weekend. One thing I noticed when doing the right side was the hole in the frame was all wallowed out. Drilled out the bushing in the upper end link and used a bigger bolt to fill the gap up. went for a drive and the clunk was way worse than it ever was still on the left side. So I took off the left one and went for a drive. Sure enough no clunk, the left one was wallowed out as well. So I did the same thing on that side and the evil clunk is finally gone. Just thought I would throw that out that if have a clunk after replacing the end links, Check the upper holes.

On the way to work this morning in stop-and-go traffic, I noticed a new, weird noise from my week-old 2012 GTI with less than 500 miles on it.
The noise happens when letting of the gas in gear. Doesn't matter what gear you're in or what the engine speed is. Around a second after getting of the gas, there is a loud, depp bass thump, almost like a subwoofer hit from a close-by car. That's what I originally thought it was, but later determined it's something from my car.
What it could be? An exhaust noise? Something hitting? Is this a common noise on the new GTIs?

I have a '02 Excursion with a 7.3L PSD, 238,000 miles. When I drive and say stop at a stop sign or light, when I transfer from the brake pedal to the accelorator and initially begin moving, I hear a slight "Thump" in the back. Could it be a sticky rear brake caliper? Bad U-joint? Sloppy ring/pinion gear? Just put AMS oil in the rear diff but have noticed slight shavings on the fill plug magnet.

Just purchased a used 2008 HH - about 85000 miles. Seems to work perfectly except there is a very loud hum that sounds that it is coming from the rear. Starts to be noticeable at 30 MPH and gets louder up to about 55, and then isn't as noticeable, perhaps due to normal road noise.
