Lexus GX 2004-09 :: Clunk / Loose Suspension When Going Over Potholes
Dec 26, 2013
My 2006 Gx470 Sport (KDSS), with 82k miles, has a clunk/loose suspension feeling when going over potholes. It doesn't happen when going over speed bumps or anything other then a pothole.
I have experienced at each corner of the suspension, so it isn't just one corner that is bad. So if for example I drive over a pothole on the driver side, I feel the clunk on the driver front wheel as it goes into the pothole, and then again as the rear driver tire goes into the pothole. The same thing happens if I drove over a pothole on the passenger side as well.
Since it happens at all 4 corners, I am wondering if it may be something wrong with the Xreas Suspension, or KDSS.
Also, this is the first vehicle I have driven with KDSS, so maybe this is a normal feeling of that system. Everything else with the suspension feels normal.

New LS 460 owner (2010 swb). Owned the car for two months now and started hearing a clunk noise from the rear when the car accelerates very slowly. Showed it to the dealer and they could not replicate.
Also hearing a water rustling noise from the right side (appears to be coming from the passenger door); again, this occurs only when the car is accelerating gently from rest.

Every year about his time for the last six years my 04 rear suspension starts to clunk. Sounds like a spring trying to reseat itself. I will raise the rear end, slide under on my 40 year old car, shake out of the suspension components and won't discern a thing. Never have been able to reproduce that clunking. I suspect it is the spring seats. By April, the clunking will be gone so I think the ambient temp has something to do with the noise. The strut mounts seem to be tight to the body so is the wear in the spring isolator or other components?

Have just picked up a 2011 Tiguan Highline, and there is a loose clunk in the front going over high frequency bumps in the road. I own a MKIV Jetta TDi and it feels similar to bad sway bar bushings on my MKIV, however it's not the bushings on the Tiguan.
I crawled underneath and tried to find looseness in the suspension with no luck. The sway bar end links seem tight (compared to the MKV Jetta I also have), and the strut mounts do not seem to be loose.
What I did find were some suspect control arm bushings. I'm new to suspension noises in this platform, our MKV has been flawless for the past 7 years. Could these worn bushings cause a loose clunk?
I also checked the subframe bolts and fuel lines that come up in common searches.

I have a noise in my rear end, if I grab the bed of the truck, and rock the body back and forth, I hear a clunk, almost sounds like a wheel is loose, but checked them, all good, also checked the U-joints, and pulled the driveshaft to grease the spindle. Thinking it could be in the third member, maybe the Differential pinion shaft, or the lock bolt......

My 03 Camry LE has a weird clunk/rattle in the rear driver side only. This happens when i go over bad portion of road, not like potholes just uneven bad road. When the suspension moves quickly. Car has no weight in back. It sounds like something metal is loose in that side, the other side is tight and makes no noise. The struts were replaced in january by previous owner, someone told me it was the rear links which i replaced and still same issue, checked sway bar bushings and those are good.

But I'm still getting a grinding/clunk noise and general loose feeling from the front end. The only play I can feel is when I grab the u-joint/knuckle and pull up and down on it. I also noticed the seal at the end of the axle shaft tube is not there on 1 side... would this lack of seal cause the looseness?

I was trying to replace the bulbs in the running board and the first bulb I tried to replace when reinserting the bulb came loose and fell in the housing.
Is there anyway to remove the running board light assembly or how to get the bulb out of there?

I was driving my mother's 05 GX (non-kdss suspension).
The steering seems to be quite loose at speeds above 100kph (60mph).
There is also a vibration at these speeds (likely relating to balance).
How tight is your steering?
If alignment/balance doesn't fix things, what other parts might be the culprit?

Today I happen to notice that both sides of my running board rear light is loose. Tried a bit and did not figure out how to put them back in place. Since both sides got loose, I guess it is a quite common issue?

My 330 had a new windshield installed prior to purchase and shortly after, the rain sensor module came loose. Cleaned things up and epoxied bracket in place, and about a year later it came loose again. Seems temperature related - a hot sunny day and the epoxy loses adhesion. I'm ready to try again but at odds as to what adhesive to use. Any long term successes out there?

2016 tiguan sel. To make a long story short I drove a '14 r line and was told the '16 SEL would drive the same because they changed the trim lineup. The Sel has a noticeably more loose steering, braking, and suspension. It also doesn't hold revs the same. My sales person was an idiot and I couldn't drive model I bought because they had lost the keys and it was the only one they had.

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?

My 2005 GX (108k miles) seems to be in great shape. When i replaced the front CV boots i looked carefully at all suspension components and i did not see anything damaged, loose or suspicious.
However, when the truck is SLOWLY moving (entering into my driveway or getting out of parking spot), and when i turn the steering wheel ALL THE WAY to the right, i hear and almost feel a single semi-loud clunk from under the car. I am 99% sure it is related to the steering movement. When the car drives straight or when i am making smaller turns on the street, there is no clunk, noise or vibration at all. I haven't noticed it during U-turns yet, but maybe i haven't paid enough attention. Something must be loose or worn out. The clunk is very obvious when it happens.
Where this could be coming from? Any well known weak components in the front suspension setup that may need attention at 108k miles? I am thinking about tie rod ends or sway bar links but i am not sure if a bad tie rod / link would produce such "clunk" when turning all the way.

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?

So I have had my coilovers in for a little less than 2 months now and i have been noticing that my front suspension is becoming loose at the mounting points under hood and needs to be re-tightened periodically. I will say that unfortunately i have to drive in and out of some steep inclines and funny angles where it puts the car into tripod mode regularly. I'm not rubbing anywhere (fenders or bumpers) upon entry or exit but I am very low and really getting every bit of movement out of each corner, lots of creaking and popping (all from front, rears are fine) until tightened then its quiet again, but it all comes back after 3 or 4 days. I haven't tried driving for a week without hitting the steep inclines so I'm not sure if this is even the reason. But its the only thing that i can think of.

I have a sound that sounds like something is loose in the left front suspension area. A few weeks ago I put on VWR springs and 034 strut mounts. Then I got a tire rotation and alignment with in the same day. On Friday night it started making noise. While driving at any speed and the slightest bump I will hear the noise. There is no vibration in the steering wheel and nothing seems off about how the car handles. When I parked the car I tried pushing down on the front end and I didn't hear any thing abnormal. I jacked up the car today and I looked around and felt around on most of the suspension to see if anything was loose or out of place. I didn't notice any thing.

I am in my new gti, owned for 6 days, waiting for a tow truck. I was driving down the freeway when it felt like I blew a tire. I pull over to the side of the road and none of the tires are flat. I look under the car and a piece of the rear suspension has come loose and jamed itself in front of the tire. Its a long peice of metal with a hook on the end.

I have a new-to-me 2007 GX470 with 150k miles. Clunk sound doesn't always happen and is not that bad. It usually happens when I stop quickly, not on a gradual stop. 150k service was done 2k miles ago, so it might have been greased.
Will this cause any issues with the vehicle if drive shaft is not replaced? Is it just annoying? Is there any chance that Lexus will fix on a vehicle with 150k miles?

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?
