knocking noise when i turn the steering wheel
everytime i turn the steering wheel i hear a knock and i can feel a small vibration in my feet coming through the floor.anyone know what it could be. i had the same problem in my old celica but in my celica it was the cb joint that went dry. but my car doesnt have axles in the front. i searched the forums and didnt find anything.

HI elchinocache, if its what I think it is then you might have had the same problem I had. I use to have a C240 and when I would make a turn to park the car or come out of a parking place and turn the steering wheel I would feel and hear a knocking sound. I took it to the dealer and it ended up being what they called " the control arms". The C240 between 2001 - 2003 is know to have control arm and suspension issues. Let us know what happens. Good luck

i had a knockin sound before when turning the wheel full lock, we thought it was the control arms, but it ended up that the 2 rubber bushings holding the steering rack needed retightening, and some metal trimming as the metal inserts were rubbing with each other.

I have the same problem.
First thought it was low on power steering fluid.
Topped off the fluid level but noise is still there.
Knocking noise when the wheel is turned to the right.
Going in to shop tomorrow.

i have the same issue when i turn the steering full (to park or pulling out of the garage).. as much as i wanted to go to the dealership and have this looked at.. i think it comes from the right-front wheel (only). a month ago, i slightly rear ended another car, the front right side was pushed a bit (barely noticible). would the dealership point this out as a cause of this problem? or they will still fix it under warranty? i don't want to go there only to be charged for any other "necessary" fixes that they may charge.

I read a TSB about this for which no remedy exists yet.
Cause:
Torsion of the hydro-mount in the strut rod.
When maneuvering, the hydro bushing end stop plug can collide with the inside of the outer sleeve.
In isolated cases, this surface can exhibit pinpoint wear depending on the operating conditions of the vehicle. This wear is caused by the end stop plug resting against the outer sleeve during braking maneuvers.
As the end stop plug slides over the damaged area, fluctuations in friction pairing occur which cause the knocking/creaking noises.
Note:
The noise can generally be reproduced by driving a figure-8 in reverse. If the noises occur during this maneuver, the steering gear is not the cause of the problem and must not be replaced.
Remedy:
No remedy exists at present time
