Hello,

I have a 2004 IS300-automatic.
As I am slowly accelerating, I feel weak vibrations coming from the
steering wheel, and I think the car as well, between 55-65mph.
I've had all tires balanced twice, and they are in perfect balance.
While I feel the vibrations, I have put the car back in Neutral, and I'm very sure the vibrations disappear.

What's the problem here?
Pleae advise.

Thank you.

Jon

 

Possibly the tires are out of round or a bent rim. I would check the front end out and make sure there is nothing loose.

 

I was told probable cause could be ball joints. May want to check with the dealer. How many miles are on the car?

 

The car as about 41K mi.
I have never ever hit anything, nor went over
big pot holes.
I pretty much baby the car, and even slow down
@ railroad tracks.
I'm hesitant to bring it into the dealership because
during the test drive, the tech may not feel the
slight vibrations. My time might be wasted there.



Thanks for all your replies.

 

i recommend taking it to the dealership. when you go there, you can request to ride with a tech so he/she can see exactly what you are talking about.

it could be a number of things. just because the tires are balanced, doesnt mean the tires do not have excessive road force (out of round), you could have a bent rim, something wrong in the drivetrain...
