Rowdiggty

I hear and slightly feel a banging sound when I go over decent sized bumps. It seems to be coming from part of the steering assembly. The wheel and column feel solid but I can feel the slight vibration coming from the steering wheel.
Any ideas or anyone experiencing the same thing?

im experiencing the same problem right now. have you found the cause of this problem?

Rowdiggty

I havent. It seems to happen the most if I have to come to a quick stop and the road is fairly rough. any luck?

may be your motor mounts going bad?

Steering rack bushings need replacing most likely. I had the same issues especially when wheel were turned.

Rowdiggty

That makes sense I think I'll start here.

there's 3 cv joints in the steering shaft... you should replace at least 2 of these (lower and middle) if nothing helps

any lucky with resolving the problem? i recently changed both my upper control arms cause there was play in them and it made the problem a little less noticeable. but its still there when i hit a really big bump.

I have the same issue. My steering has never been quite right on this car. Lexus replaced my lower control arms it was much improved but the noise is still there.

I replaced the steering bushings when i first got the car.

i had vibration on my steering wheel before...i retorque the wheel and the vibration is 95% gone. i never use impact gun on my wheels even tho it makes the job faster

I had a problem like you stated. It turned out to be a loose alignment nut. Had the nut tightened and alignment and all is good. Everyone kept telling me it was control arm bushings. Not

This is one of the very common problems in the LS430. And it just happens by time.
Th secret to getting it feeling firm and back like OEM again, is to change "a part right behind the steering wheel" ( I'm sorry I don't know the exact name in English, but I'll try to describe it.)

It is located right behind the steering wheel, it connects the steering wheel with the front wheels. It's like an adapter.
It's circular in shape and has about 4 bolts if I remember correctly.

I'm sorry I couldn't provide the name. But I'll be happy to help you more if you PM me.

Good luck!
