Hi!

in my 2009 IS250 AWD I've observed a weird knocking/rumbling sound of front wheels. IT comes up when I turn on a wet surface (asphalt or paving stone).

I have proper tire size and pressure, regularly changed steering fluid so I'm worried about that.

I drove a service once and they told me that due to the AWD system, the wheels bend over differently and that where the sound cames from. I don't think such story can match Lexus but mabe somebody can help.

Regards,

Worn/bad CV joints in your half shafts?

Sounds like your CV axle is wearing out. It can knock and still last a good while.

I have the same car. Haven't had those symptoms but the dealer indicated my cv boots / axle was leaking. it was minor so just recommended I keep an eye on it. they said if I hear clicking def get it checked out. so that could be prob. Def get axles looked at

Thank you all

on the 24th of November I'm visiting my service guy and tell him to look at the CV's.

I bought from old spare parts and replaced it. But issue still there and no clue what is exact problem. Any suggestion
A​​​​​​nother mechanic suggest to check steering control computer as May be faulty?

Hi

do you have the steering fluid? Maybe a leak of lack of it...?

rizwansial

no it's Electric power steering

ArtIS

Sure? It totally doesn't act like. Mine works tough since 2013

Yes. It is electric driven by motors. If it's stiff, you should have that checked out.
