Lexus GX 2004-09 :: Clunk In Rear End When Slowly Drive Over Speed Bumps
Oct 14, 2015
I recently bought a CPO 2007 GX 470 with 110k miles. At no charge dealer made repairs re the Bulletin about clunk in rear when I slowly drive over speed bumps. Had all front and rear shocks raced with OEM shocks, and four new Michellin MS2 tires installed. Rear end still feels like is is bottoming out sometimes during regular local and freeway driving when going over different times of road bumps.
My 'i89 a Dodge Ramdharger ( only car I ever bought brand new off the lot ) with 174k miles and old shocks and original springs drives better over bumps and speed bumps than the GX. One Lexus dealer said the reason is because the rear air bags ( that are not leaking )do not fill up fast enough when going move bumps and that can cause the bottoming out feeling. My mechanic is going to check it over again. What could be causing the bottoming out feeling?

The front struts n my 2010 camry se with about 51k on it and it makes a horrible clunk and pop noise when going slowly on uneven roads and over speed bumps. I got out to check the cause and found it to be he top of the strut coming through the strut mount is making the popping sound and seems like it has more than normal movement... does this happen to many? is it a common issue...

Problem is noise that you can describe as clunk, not any harsh or sharp sound. It appears on road bumps or unevenness during slow speed up to about 40kph/25mph. The noise has not been heard over that speed even in bad bumpy roads.
List of thing I've done so far:
- Driven with empty rear compartments
- Driven with open rear door
- Checked the tightness of spare tyre
- Replaced rear stabilizer bar linkages
- Replaced rear stabilizer bar bushings
- Replaced rear axle carrier knuckle bushings
Could it be possible not coming from rear? Should I sit in the cargo space while somebody else driving, any success with this? What to do next?

So I know the 2013 GS (or many GS in general) have had complaints of squeaks and rattles. My GS has a couple but are very minor and only occasional.
I do have one noise that seems unusual though. When I am driving and drive over moderate bumps in the road, I hear a muffled clunk or thunk type of noise only from the rear passenger area and never anywhere else.
My car is a stock CPO 2013 F sport and not lowered or anything. Stock rims and tires. The shock does not seem to be leaking.
The noise happens regardless of if I am in regular or sport+ modes. Was going to mention it to the dealer at my next oil change and door trim replacement appointment I need to make Ina couple months.

I have a clunking sound coming from the back end. It is most noticeable at lower speeds going over bumps. I can also make the clunk happen by grabbing the top of the right rear tire and rocking it. I can feel something moving while I am doing this, but I can't pinpoint it. The bushings seem to be in good condition. The left rear wheel bearing was replaced recently. I also have an intermittent brake pulsation which feels like a warped rotor. I don't think it is actually the rotor, because it doesn't happen every time I apply the brakes. I believe that these two things are related. Is it possible for the rear struts to cause these issues?

When I drive over quick choppy bumps in pavement I get a rattle in the rear of the suspension, but only when the bump is on one side. When the bump is long and activates both rear wheels, like a speed bump or a large road crack I don't get the rattle.
The sound seems to be worse on the right side and I can't really figure it out. Anything specific I should look out for?

I Spent the day yesterday replacing all four struts on my '07 LE. I went with KYB, the installation went well (so I assumed). I put everything back together exactly as I took it down. Outside of the struts alone, I reused all other parts as everything seemed to be in good order.
Test drive: I seem to have a knock/clunk when going over bumps/pot holes at low speed (<35 and especially <15mph). At highway speeds (65+), I do not hear it at all, even if I hit something. I had a friend ride in the back and confirm that it was coming from the driver's side (left) rear.
Took everything back out and inspected, I noticed that the strut mount has a flange that runs to the flat side of the strut rod that looked a little worn, so decided to go buy a new strut mount (Monroe garbage, only thing available locally). I did notice the Monroe strut mount didn't have that flange the OEM one had, it is just a circle...I didn't know if that mattered. I Put in new strut mount on, same sounds in the same conditions. I want the clunk to go away.

I have a 2004 F150 4x4 5.4. Over the last few weeks I've noticed that when the truck has been parked for even a short time, when I start to move out I am getting a thumping noise from the rear, almost sounds and feels as though I am driving over small speed bumps, but once i get going it seems fine. Where to start?

I got a TSB done on my clunk about a year ago. The old clunk felt like the car was hit from behind at a low speed collision (I have the experience). But now the car has developed a different type of clunk. Now it feels like something is hitting me from directly below my feet. I can actually feel the vibration right between the sit and pedals. What gives now? Is it the same thing, anything to worry about?

I have a 2007 Sonata Ltd (63000 miles) and had a clunk in the front suspension. I had the front upper control arms replaced (which were visually badly worn) and that fixed the problem. But now, a several months later another similar clunking noise has developed when I go over those small speed bumps in parking lots.

I have less than 1000km on my new 2014 XTR SC. I had an AS 2.5/1.5" kit installed and a wheel alignment. There is a dull clunk in the rear when driving slowly over rough terrain(dirt roads n potholes). It happens occasionally when taking turns at lower speeds too. A friend who is a mechanic installed the kit and its the 4th kit he has installed for me. Never an issue.
The truck had to go to the dealer to have the remote start installed and they investigated the clunk and tightened up some nuts and bolts and its still there. They blamed the leveling kit and said its normal sometimes. This is definitely not normal! I've searched and can't find anything.

I've had this problem for years but is now getting worse. It used to only happen when it was really cold out, subzero, but is now happening as we now approach 50 degrees out. If I hit a pothole or pop over a small curb, I get a clunk in the rear. I replaced the shocks about 3 months ago which seemed to work briefly but the problem is back and is worse than ever.
I have the original springs and it looks like the recall was done by the previous owner (rubber bumber stops installed).
230k miles. Do I need new springs?

I have had an issue with a clunk in the rear end. Passenger side. It was only happening when I would hit a bump. Over the last couple days it has started getting worse. At about 40 mph and above the clunking will increase and can be fairly rapid. Also have a slight vibration at that speed. Do not feel it in the steering wheel.
I think I have narrowed it down to the rear knuckle? bushing. While holding onto the bushing I rocked the top of the tire in and out to produce the clunk. I could feel it in that spot. I had ordered a set of bushings, months ago, which claimed to be a direct replacement.
Tonight I decided to try and swap them out. Should be easy. Nope. The old bushing will not come out. I have some pictures. Maybe I need to call my mechanic in the morning? My diagnosis might be wrong anyway?

I have a 2005 king ranch and have a clunk coming from the back over bumps/heaves in the road. It doesn't happen all the time but often enough. I just replaced the shocks, that worked a little but didn't solve the problem. Now thinking rear sway bar end links? Anything I can check/inspect?

I would like to post this performance issue on my 2003 GX470_79Kmiles which happened on the freeway yesterday. The sequence:
1) During start and at idle/stationary, the rpm shoot to 1100rpm and stayed there for a while, i would think that it was normal since the engine was still cold.
2) Drove to the freeway, I noticed that speed is very slow to pick up. My normal driving experience was that at close/equal to 2000rpm, the speed usually at around 70-75mph. But there was a considerable reduction of speed at around 60mph at almost more than 2000rpm, plus a buzzing engine noise. I tried to really rev-up the engine but very sluggish to pick up the speed not even close to 70mph.
3) Drove the car to lexus shop this morning, top speed of 60 to 65mph and tried to rev it up to plus 2000rpm to pick up speed, but the engine noise is very abnormal.

I have a 04 4.6 f150 4x4. I have had some off road wear on the truck but put a stop to it here recently. I have replaced ball joints , struts , sway bar linkage , hubs , and now have a clunking sound going over every bump no matter the speed. Everything is tight underneath while stopped, other than the front driveshaft. It seems to have too much play to me? What it could be ???

In the last few thousand miles, I have noticed that the ride in the rear of the car is rather rough compared to new. For instance, you can feel the roughness and choppiness from the driver seat. When going over speed bumps, the rear end also does not seem to rebound nearly as well as the front. The front struts though, are working just fine.
At first I tried rotating and balancing the tires; the improvement was minimal. At the time I had springs from TRD on the car, so I reinstalled the original Toyota springs from the factory. The rough, choppy ride from the rear now became less noticeable, but is still there. I currently have 43,000 miles.

I'm new to vw and I have a passat 3.6 sel premium and I have been hearing a noise coming from my rear suspension when I have a full car or going over speed bumps and such. It took it to the dealer and they said that they couldn't replicate the problem, could it be the control arms or it's bushings? The car is only 6 months old smh.

So on the 16th I had my Koni FSD kit installed with a set of Driver Gear springs (30mm drop) and used the ECS Tuning install kit for both front and rear.
The issue I'm trying to troubleshoot is a 'thunk' noise coming from the rear but only when going over speed bumps or any other major bumps/dips.
