Lexus GS 2006-11 :: Bump Steer When Hit Bumps On Highway
Apr 11, 2016
Here is the spec of my gs: 20x9.5 front(-2 camber), 20x10.5(-4 camber), I have fig camber arm (upper&lower), toe arm and trac arm installed, and alignment done, but I still get that bump steer when I hit bumps on the highway. Why it's happening?!?!? do I need to change the outer tie rod then the issue will be fixed? Or is there anything I can do to fix the problem. Since Figs Engineering does not make outer tie rod for the 3rd GS, is Moog tie rod will be ok?

I have a Gs 430 - 2006. After hitting bumps in the highway big or small it seems like my dash or suspension squeaks inside the car. Since I can hear it so clearly I'm leaning towards its the dash or something behind the dash, It seems to be coming from the drivers side.What could it be?

I put on a leveling kit a few months ago and pretty much replaced a lot of worn out parts in the front fenders. With the exception of lower control arms, shocks and springs. Just about everything else that moved was replaced I think.
Well now it seems like every time I hit a decent bump in the road my truck jumps to the side. It's very noticeable if I'm going around a corner and hit a bump. The steering wheel is thrown from side to side so I'm fairly certain that the issue is up front but don't really know where to start looking.
The truck may have done this before the leveling kit but it's very exaggerated now. It's so bad at times that my husband won't drive it.

Got the death wobble, had everything replaced. Wobble was worse, upgraded track bar. Then no wobble but bad bump steer. Put on new OEM track bar.
Ok but still if I hit a hole on the interstate I get death wobble and little mini wobbles on any bump. What is the permanent fix for this other than selling the truck?
2011 6.7L FWD Lariat, upgraded exhaust and Def removed.

When I make a left, my car makes this eeek...eeek...eeek noise, when I'm going straight and go over a bump there is no noise, I press the brakes on all stops no noise, making a right no noise... I tried checking the front left brakes today and it looks fine, I even cleaned it a bit and it's still the same.

So, recently I've been noticing that my suspension or somewhere in the front that it squeaks every time i go over a medium - big size bump or pot hole. (avoiding big potholes of course). The suspension feels fine as in after the bump there is no continuous bouncing... Could my coils be going bad?

2007 GS 350 AWD in power mode, 22,000 actual miles on the car.
Pavement - dry
When going slowly over a neighborhood speed bump after about 2 minutes of low speed engine operation (engine still cold), the transmission seems to disengage, spinning in neutral for about one second, then it engages.
This doesn't happen when the engine is warm. Is this normal? Is it a problem?

My 07 gs350 only has 67,000 miles on it, and I've only had it for 2 weeks. I've noticed a rattle in my dash, seems to be up where the front windshield meets it. It only seems to happen when I hit bumps, which is quite frequent. The roads here in Michigan are absolutely terrible. Also I have run flat tires on it, which I heard makes for an extra bumpy ride... Is this a known problem? If so what's it gonna run me to fix it? Or is it just these run flat tires that I need to change maybe?

More lately I've been noticing that when moving slowly, if going over a bump in the road of any sort, the steering wheel seems loose and the car wants to jump to one side or another slightly.
Picture moving straight ahead, and hit a rough section of or a small pot hole, and the steering wheel will move by itself to the left or the right quite a bit. I haven't noticed anything on the highway.
What can cause that? How should I go about describing to the service advisor so that it doesn't seem trivial? Last thing I want is a steering rack or major front suspension component slowly dying right after my warranty runs out. All I know is that it has struck me as "hey this doesn't feel normal".
Am I just being overly sensitive now that my powertrain warranty has months left on the clock, or does this sound like a legitimate concern? The last few things I've had them look into at the dealership during other service visits have been returned to me as "no problem founds" and I'm starting to feel like I'm just going crazy.
After some additional googling, it seems like I'm describing something commonly called "bump steer"... how much bump steer is normal for this car with stock suspension, I don't know... all I know is that I seem to have become acutely attuned to it whereas I never noticed it before. Hopefully I don't get the "we didn't notice anything wrong" again if I mention it, and whatever it is, is covered.

Engine idling on D and idling on N/P. Mine sometimes runs at 600, sometimes at 650. When I steer, rpm should go higher but it doesn't go.

It's strange because it doesn't happen over every bump and sometimes doesn't go off over pot holes, but switching lanes and going over the lane reflectors on the road will set it off. It happens only on the driver's door. I tried a DIY and while it doesn't happen as often as it use to, it still goes off from time to time.
Car is an 08 GS350 RWD.

I had the cam gears on my 2009 RX350 replaced and after the replacement I noticed that the engine noise is louder. It's louder after a cold start and idle. And it's louder when driving. Even the transmission sounds like it's struggling - it's taking much longer to shift into higher gear and occasionally it makes a whining sound when it shifts. Also, I'm hearing whining sounds when I steer the wheel (which was diagnosed as potentially caused by a faulty power steering pump, which by the way did not cause any noise prior to the work done). The replacement was done by a reputable Lexus dealer.
The Lexus dealership claims that the engine noise level is within acceptable limits even though it is much louder than before the cam gears were replaced. They deny that the replacement cam gears could be defective or that the replacement itself could have gone wrong. They have acknowledged the noise coming from the transmission and have offered to replace it (still under warranty so no cost to me). Now what is strange to me about all this is that prior to having the cam gears replaced, the engine noise was very quiet. The only occasional noise came from the cam gears on cold starts but lasted a second or two.
Now I don't know for sure that replacing the transmission will fix the noise issue. And it is so strange that the transmission seemed fine prior to the work done. What's happening here given the facts? Could replacing the cam gears somehow damage the transmission? Is there any interaction between cam gears and transmission. Aside from the transmission, what could explain the much higher engine noise (when not shifting so transmission not a factor) after the cam gears were replaced?

I have a very well maintained 1998 Ford Explorer 4.0 SOHC 4X4 with only 67,000 miles. Sometimes at highway speeds ( 65MPH ) there is a fairly pronounced bump / jerk. I will also happen occasionally when accelerating from a stop. IMHO, it's not a slip. Fluid has been flushed and is bright red. The best I can tell the RPMs are not jumping when this happens. I've all but counted out an engine misfire. There are no engine or OD light on. Where I should begin troubleshooting? I don't want to spend tons of money trying to isolate the issue but this Explorer is in exceptional condition so I want to have it fixed.

Noticed the seat shaking when at highway speeds or when you go over bumps in the road? When my seats are empty, they shake and make an annoying rattle, shakey noise. I had them looked at by Hyundai and was told that there was nothing that Hyundai was going to do to fix them. After battling that for a while, Hyundai did reimburse me a car payment for me to "live with it" and, quite frankly, to shut me up.

2009 Hyundai Sonata automatic: When downshifting from 4th to 3rd it feels like I hit a bump, or like I just hit the brakes hard for a second.
What could it be? It's most noticeable when the car is cold. I have 82k miles on it, so it's still in the "power train warranty".

Every time I go over a speed bump faster then 2-3MPH There is this terrible thump / rattle that sounds like a rusted out 1993 Buick Riviera with blown out shocks.

I have recently started to have the exhaust rattle on my RX330. It occurs every now and then when the car is on an angle or more particularly when going over a speed bump. I had been trying to find out where it was coming from and it looked to be the exhaust possibly touching the plate that separates the exhaust from the spare wheel cover (which of course is plastic). This is the part I am talking about....
Now the first part of me thinks that to resolve the issue it would be handy to put some padding there to stop it from rattling against the shield when the exhaust does move. The second part of me also thinks, it might be time to replace the rubber holders as they seem to be particularly soft and have quite a bit of give to them. Now for the interim I would want to put some padding on there. What padding have to put there? Would exhaust wrap be the most obvious choice to wrap around the shield?
Trying to find an inexpensive temporary solution. The long term resolution would be for the actual rubber rings themselves to be replaced as well as having that small metal bit covered in some sort of wrap to prevent metal to metal touching (hence vibration and noise). Part of me also thought to remove the shield altogether, but worried that the exhaust may touch the plastic around the tyre and cause it to melt and possibly catch fire, as it does sway a bit.

Shortly after we got our 08 ls460 my gf asked if I had felt a weird brake issue. She said it was like the car would "jerk" or "bump". The way she described it was more like how a car with an auto tranny will "creep" if you aren't holding the brake pedal down firmly. Yesterday I was driving the car, with her in it. Stop at a light. All is well. Brake off, gas on to leave...It felt like someone hit us on the left rear of the car. I actually stopped and looked behind us to see what the hell happened. She says "that's the feeling I was telling you about". When we got the car I had it on a lift and noticed the left rear sway bar link was broken, but there was no damage to indicate a reason. I can't find anything else on this problem anywhere and can't tell if it's brake related or trans related. Our local lexus dealer is going to check it out on wed at 9am.
Calipers were in great shape when I did the brakes with no hanging or signs of trouble. Everything works like it should 99% of the time. But damn if that 1% won't scare you.

I just turned 200,000 miles on my 2004 GX470. I am the original owner. I had a very good experience with my GX. Besides the normal maintenance jobs (brakes, tires, spark pluds, belt) I have not had any other major repairs. However, the last few months, the car waves sideways when I hit a bump on the highways. It sways sideways. I checked the sway bars and the appear to be fine. What did you have to change to stop this wavey ride?

I have been experience some rough ride, and i am always in "comfort" mode for the air suspension. I have been changing the suspension over to "sport" for a mile or two then back into "comfort" and that seems to fix it for a day or so and then it goes rougher again.
I have also noticed when i am riding with the windows down that every time i hit a bump not only is there a jarring jolt, but also a squeak almost like a shriek that comes from presumably the suspension in the front ?
I would like to know if this is a sign of failing air bags, a bad compressor, bad sensors or even if the control arms are in question at this point. . .?
