Lexus SC430 :: Steering Wheel Starts Vibrating At About 65 MPH
Jul 23, 2013
I recently purchased a low mileage 2002 SC 430. The steering will starts vibrating at about 65 MPH, and it lessens, or even quits vibrating at about 80. I am not sure if it is the tires needing balancing, or the current set of tires not being particularly good. I think the tire brand is Rotalla, or something very similar. I would like, when it is time to put a new set of tires on the car, to get some non run flat tires (I am not sure whether the current set are run flats or not), as I read on this forum that the ride is much better on non run flats. However, I do not have a spare in the trunk. Are the small, temporary spares easy to come by? Does Lexus sell them and how much? Is there any other alternative to consider as I do not particularly want to get a flat when driving in the country without a spare.

When I turn my AC to max. power (fan) the steering wheel and the entire dash board starts shaking and vibrating. Also one can hear a "deep" humming noise which seems to be coming form the fan/fans belt etc.

I just put 20" Status Game wheels on my 07 GX. I have had them balanced twice and between 55-65mph the steering wheel vibrates considerably. Is there a fix for this? New steering box valve, hub rings.

I have a 1998 Lexus GS300 with 178,000 miles. I feel a shimmy in the steering wheel at about 60-65 MPH. I don't feel it at slower or faster speeds than the 60-65 MPH range. It also seems it's worse at the beginning of a drive and improves with time, but never really goes away. It has been going on for a few years.
I thought a when I bought new tires few months ago and had them balanced and aligned that the shimmy would go away. It did improve, but it didn't go away completely. My mechanic said to put 500 miles on the car to break in the tires then bring it back in to re-balance them. That didn't work.
He said that it could be the struts, but that they aren't leaking. I plan to keep this car for another 60,000 miles. Have the struts gone bad? Does it need to be replaced? Is it safe to drive if I don't replace them? Any consequences if I don't replace them? Is it worth it?

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.

Just rotated my tires this weekend and noticed today that the steering wheel has a vibration in it at highway speeds, 65-70mph. It did not do this at all before I rotated the tires, why it's doing it now? Tires are fairly new and Bridgestones H/Ts.
I know my rotors are warped and need replaced but the vibration I'm referring to is when I am not braking.

I own an 08 Rx350 at 70k miles now. This is my first car ever; my parents bought it brand new and gave to me as gift after I graduated from college. I try to take good care of it; whatever the dealership tells me to replace, I replace it. I follow the maintenance schedule and owners guide to a T. I never really paid attention when my parents drove this car...but I don't know why my car vibrates when I get maybe above 60 mph and try to apply the brake. I do not brake hard and now I pretty much avoid applying brake and just let it glide. Is this normal? Whenever I visit the dealership they do a complete check up. All the check up results are normal;nothing wrong with tire trims, brake pads, suspension etc.

Had the shaky steering wheel @ 50-65 MPH. I remember this happened to my other car after the brakes were inspected. The tech put the rim on without cross tightening the lug nuts.
Anyway I took off the wheel and noticed the brake rotor was not lined up with lug bolts. In other words the bolts were not centered on the holes of the brake rotor. So I broke the rotor free and lined up the holes. Put the wheel back on and now no shakes at 50MPH. I do get just a little of shake on braking at high speed but thats all.
I think the rotor can get stuck on the edge of the bore and not able to seat firmly on the spindle.

I had a issue today and it made me scared to drive the SC ever again. While I was driving this light came on that kept blinking and making a beeping noises, after a while of blinking (approximately 30 seconds) the steering wheel jerked to the left and right really fast, luckily there was no car around me. I immediately pulled over to the shoulder. After a couple minutes I drove home on the service road without incident. Why this happened.

2002 SC430 with 50k miles. I have a set of aftermarket Dolce rims that are 18" with the stock size tires. I have the eccentric spacers on them as well. They have been mounted and balanced. I also have a set of Dunlop snow tires on my stock rims. Obviously I do a seasonal change over.
With either set of tires I am getting a steering wheel shake at 60-65 mph. By 80mph its gone and the car glides perfectly. There is no pulsation in the brake pedal and there is minimal wear on the pads. Below 60mph there is no issues as well.
Tires are wearing evenly. Some roads will make the movement worse, but it always goes away at around 80 mph.
Now both sets of tires were mounted and balanced by the same shop. I assume that could be it...there machine is faulty. But I would like some other possibilities before I try somewhere else.

2002 sc430 73k miles.
I have a slight steering wobble (not really shaking/vibration) at higher speeds and only when I turn the wheel to the left or right a little (maybe a 1/2 inch). If I am driving straight down the highway it is smooth at any speed 40-90mph no issues. If I move the wheel to the left or right I feel the the wobble in the wheel. If I go back and forth a little, constantly, with the wheel it continuously wobbles.
I had recently addressed some other vibration issues by installing new LCA #2, continental DWS tires, and had the front end aligned (front -.3L and -.5R for camber, Rear -1L and -1R camber, front and rear toe set to -.07, if I recall). I couldn't really remember if I felt this wobble before because the tires and LCA's needed to be done badly. I am not sure if I should replace the struts either since ride feels good.
My steering feels darn good and responsive at low speeds and does not wobble when turning the wheel slightly. I have purchased new oem steering rack bushings but have not installed them yet (purchased as a preventive maintenance part when i had some free time, before I discovered this issue).
I have read a few threads about alignment of the steering rack causing issues if it is not perfectly centered. Not sure if that would cause anything like this. Love driving the car but the wobble is rather annoying when i turn the wheel a little to change lanes at 75mph.

I have noticed that when pressing on the brakes at 50 MPH and higher my steering wheel starts vibrating and it feels like the car is being tugged a little to the left. This started a couple of weeks ago, what might be causing this?

My friend with an 07 with about 109k miles on it now has started getting a "groaning" noise whenever the wheel is cut hard to the right or left, either sitting still or rolling. A local repair shop (not the dealer) checked it out and said there was some "stuff that needed to be lubricated". Not trusting this opinion he went to a Toyota dealer where he was getting new brake pads installed on all 4 corners (no Lexus dealer in the city where he lives), they diagnosed the car as needing 4 new struts and a new balljoint.
If in fact he does need the struts and balljoint, I am thinking chances are there will be a bunch more suspension stuff that should really be done at the same time when everything is apart anyway - perhaps bushings, endlinks, etc?
Is he better off sticking with the OEM strut replacements or should he go aftermarket? He's not looking to slam the car or anything, and is more of a ride comfort guy than handling enthusiast.

drive an '05 sc430 and the steering wheel shakes at above 50mph when I lightly step on the brakes. I have recently had my brakes done and an alignment done as well as both rear shocks replaced.

Strangely, after my battery died and the car was jump-started the volume control on the steering wheel is not working correctly. When I press the volume up switch, the sound actually decreases, and the volume down button does not function. The manual volume control on the radio works fine.

I'm trying to find why my car's steering wheel vibrates. This happens at all speeds regardless or acceleration or breaking.

Driving home tonight my 350 starts getting the shakes, vibrating all over the place and all of the sudden the check vsc, check engine light, skid light, and the yellow ! popped up. The check engine light starts flashing and the car looses all power, no acceleration. I pull over, shut her off wait a few mins and same thing.

Is it only me having this annoying problem that above 100km/h the steering wheel starts vibrating - sometimes less, sometimes more. I had the vehicle taken to the Dealership several times where the guys first tried to balance and adjust the wheels and afterwords they changed all 4 tyres (KUMHO) + one rim but still the vibration (sometimes resembles mild shaking like driving on rough roads) is there. Don't know if this is normal or I am just too demanding but can't remember experiencing such thing with my previous cars like audi, citroen, etc...

So what is the deal with this whole steering wheel vibrating over 70mph? I have new balanced tires and the alignment has been done already. The steering wheel has a very annoying mild shake over 70mph on the highway. When I went back to the tire shop I saw the guy rebalance all 4 tires correctly. They told me to look into getting all alignment done. The car has 123,000 miles and had the 2 front struts replaced at 83,000 miles.
