Lexus GX 2004-09 :: Steering Wheel Shaking / Vibration On Comfort Mode At About 55 To 60mph
Jun 18, 2014
I'm getting some vibration and steering wheel shake with my '04 GX... I have a 2004 GX with the differential dynamic damper installed. About 55-60mph it starts, and shakes the steering wheel back and forth. Sometimes it's completely smooth, but on other road surfaces it shakes. On full "comfort mode," the shake is much worse, but on Sport mode it dampens the shake to about 10% intensity, but it's sometimes still there. This is not bump steer, by the way.
So far, I've done:
-Brakes
-Alignment
-Front hubs
-2x wheel balancing with 2 different sets of wheels/tires
-lubed the drive shaft and prop shaft to fix the clunk (Clunk TSB has not been done)
-changed the power steering fluid
-checked all control arm bushings, ball joints, tie rod ends, and sway bar bushings. All are solid.
I recently jacked up the front end and moved the wheels back and forth by hand. It seems like there is some looseness coming front the inner tie rods. However, I pushed and pulled and can't get a clunk or anything. I think it's coming from inside the steering gearbox. My VIN says it's before ST002-05, so that TSB aka "Steering Flutter" would apply, if it is that.
After 104k, are the front shocks due for a change? It does seem to nose-dive a bit on braking, but the shocks aren't leaking or anything. Would worn shocks cause steering wheel flutter on these trucks?

My GX470 steering wheel shakes/vibrates when I hit speeds over 50mph. What is causing it?

I am currently running 8mm ECS spacers in the front and 17.5mm ECS spacers in the rear. My Summer set up is still stock BBS RC's, but my winter wheels are Lenso's.
Last winter was my first winter running with the Lenso's and had no issues. This past weekend I swapped out the BBS's for the Lenso's, and now I am feeling vibration above 60MPH. I felt no vibration with the BBS's. I just took them in to get balanced (maybe a weight fell off-idk), and they were within 1/4 of 100% balanced. They then thought it may be the spacers I'm running so they cleaned them up, but said that it didn't work.
My alignment is also spot on-so that's not an issue either. I am at a loss as to what would make me feel that vibration after just changing out the wheels.

700 miles ago I got new brake pads on all 4 wheels and new rotors on the rear wheels. 700 miles later the steering wheel still shakes when braking at above 60mph speeds. Also there is still a squeak sound coming when braking. Do I need to give the new brakes and rotors more time to adjust or were they installed wrong?

Haven't noticed it before, but now I pay attention to my steering wheel - when the car is stopped on Drive mode I can feel a slight vibration on the steering. Shifting to P mode eliminates is. Is it ok? Do Your steering wheels vibrate when You stop at the traffic lights?

Just had my prius for a little over a month now and I ran over a nail, had the tire patched. Once I started to get back on the road, the wheels would shake when I go over 60mph. Ive had the tire balanced plenty of times and replaced the hubcentric ring since I have after market wheels on them. The wheels are 17" drag dr31 wheels. I am still having the issues, will replacing the tire fix the issue? The tire is located in the front drivers side.

So today I took the gx470 on the highway and once is approached 70mph i noticed the steering wheel shaking... never before have i noticed this but today it happened i guess sporadically... just the steering wheel and nothing else... is this just the alignment? bad road? excessive speed? funky... lmk

Lately my 2007 GX470's steering wheel has a shaking/vibrating problem whenever I apply the brake at speed above 50 mph or so. Without braking or with braking at slower speed, there is no problem at all -- everything is glass smooth.
1. I assume the front brake rotor is warped?
2. Will I need to change the rotor or is there a way to fix the warp (it that's the problem) without changing the rotor?
3. Approximate part & labor cost?
I plan to bring to dealer for a check up but would like to know ahead of time what to expect.

I bought 09 GX-470 4K miles ago..has 50K on it. Ran perfect when we bought it. wife said it started doing it 1 week later. I drove it and felt like warped rotors to me. replaced front rotors and pads with cheap wearever brand...I Know...I was sort of trouble shooting..did nothing ...did the back rotors and pads and seemed to fix it..did proper bed-in of new parts but, never checked at speeds above 55mph. recent trip got us up to speeds above 55... at these faster speeds when brakes are applied we get a nasty wheel wobble and a pulsing pedal...braking below 55 it feels fine.. thought's ?? last car was a 4runner which has the the same rotors and pads and never had a problem...could it be ABS ?? should I go with new oem rotors and pads ?

I have a vibration in my steering wheel between 65-70 MPH. I had my wheels speed balanced with no remedy. Is this connected to the TSB for the "clunk fix"? Or could I have a bad belt in a tire? I figured if it was a bad belt than they would not be able to balance my wheels. I did recently get rear ended mildly, but there was only a scratch on my bumper- The trailer hitch took most of the impact.

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?

I hit a curb while making too sharp of a right hand turn a week ago and now I notice some vibration in the steering wheel as I drive down the highway. The tire I hit was the rear passenger side. If I get wheel balancing done, do I need to just balance that tire or all of them?

I had a balancing problem with some tires I bought with the car. At about 80 they shook and hard enough to not want to drive at that speed. I replaced them with Falken tires and it was so much better, but......
At 75-82 mph I still have a shake in the steering wheel. I bought the tires from Discount and they claim the rim is bent and they cannot completely balance the tire. I am going back once more to get a definitive response.
I am at a loss at what to do next. My other Lexus was smooth at any speed, even at 90. Smooth. 2007 Lexus es350

During an extended drive of the new ride today, we noticed an intermittent vibration when coasting downhill around 60MPH. I popped it in neutral and the vibration disappeared completely. Also, it stayed vibration-free when placed back in Drive, without touching the gas. But as soon as throttle is applied and then you coast again, the vibration reappears.
This points to a condition that only happens when the torque converter is locked, which could be a vibration originating within the transfer case that once coupled to the engine via the locked torque converter uses the engine as a tuning fork, resulting in the vibration. The L-SB-0013-12 AWD Vibration TSB mentions an ECM recalibration, which likely changes the torque converter to unlock whenever you lift off the gas pedal. Is this correct?
I also remember reading about the other TSB, where the "magic expensive fluid" in the transfer case gets changed 3 times in rapid succession. This would address chattering clutches within the transfer case, eliminating vibration at the source vs. masking it by unlocking the torque converter.
We also noticed a misfiring sensation under light throttle conditions at around 40-50MPH. I'm wondering if this is in fact the transfer case clutch chatter issue also...since the 60k spark plug replacement has already been done.

Recently I started driving on eco mode to have the smoothest ride/acceleration. However, yesterday I wanted to get my dose of sport mode and WOT, so I switched to sport mode and stepped on the gas and during a small curve I felt the car steering is stiffer than usual, so I thought it could be due to speed. After that I reduced my speed and tried switching between sport and eco back to back and the sport mode steering actually is stiffer and more responsive! . I was surprised because my car is not the F sport, it is the normal is350 with tech package, and Lexus didn't mention this when describing the sport mode.

I have a 2006 rx330 which vibrates bad between 40-60. I had a my drive shaft balanced and new joints installed but still shakes. I have bridgestone dueler alenza tires with 5k on them, had them all rebalanced. Still shakes. I have 205k on her.

Yesterday had 5000 miles/6 months service performed on 2015 3500 miles AWD RX-350. Right after leaving the dealer felt that steering wheel is too light. After some driving it returned to normal, but with very light shimmer during driving (40-50 ml/h) and stops . Today was backing up from garage and shaking was much more noticeable when reversed and parked, also it was some kind of (I think) engine roar. After that drove almost 30 miles with some steering wheel light shimmering, but no other issues.
Is it normal car behavior, and I'm just paranoid ? Or, if there is a potential problem, what could trigger it, and how it could be resolved?

Steering wheel will turn about 35 degrees left or right when one side of the street is uneven and you take your hands off the wheel ? I guess I haven't noticed it much in these 3 months because I am always in Sport mode, which stiffens the wheels as we all know, but today as i was driving in Normal, I was on a street that kind of tapered to the right on an approx. 5 degree angle and the wheel turn itself pretty dramatically. I corrected my path and it would shoot right soon as i took my hand off the wheel. Its definitely not an alignment issue because its straight like an arrow. And all tires have 33 psi cold. Then i noticed again on the freeway, i know its uneven pavement but the amount the wheel turns is pretty substantial.
Also, when you make a 90 degree turn the steering wheel doesn't really retract itself back too good, you kind of have guide it back. But putting it in Sport mode fixes all that. Besides that i love the steering, you can take turns at ridiculous speeds (not that i do ) and it eats the the turn right up, no problem, and you dont even break a sweat. The car is phenomenally well balanced. Love the GS

My truck had a slight vibration at idle today and what i noticed the most was i was looking at the top of the motor and i noticed that the fluid in the power steering reservoir was shaking back and forth like i was shaking the container. Is this from the vibration or is the power steering system vibrating. I have had this truck for two weeks and it has 135k on it. It is the 5.4 motor...

This summer, my steering rack failed, and I had it replaced with a remanufacutured steering rack. All went well, until a few weeks ago I started feeling a pulsing effect when turning, usually when turning right. On a few occasions, the shaking has become severe. It is a back-and-forth effect, about three times a second. It is bad enough that it has triggered a power steering error on two occasions. I took it to the garage who installed the rack, asking them to have a look at it, and they found nothing. Because the effect is regular, I am assuming that I am feeling the 12V power assist malfunctioning or reacting to faulty input.

Recently purchased a certified 2011 Lexus ES350 with navigation. I noticed that when pressing the mode button on the steering wheel, the radio toggles from AM, FM1, FM2, and Bluetooth, but completely skips satellite radio. The satellite radio is active and I set presets for all the stations. I can access the satellite radio stations fine when pressing the button on the dash or on the touch screen but the mode button on the steering wheel completely skips the satellite selection.
