Condition
Some customers may comment on a clunk type noise coming from the front of the vehicle during a turning maneuver. This condition can also be felt through the steering wheel when the vehicle is stationary and the wheel is rotated from steering stop to steering stop. Typically, the clunk noise will be heard once for every 90° of steering wheel rotation in either direction. This clunk noise may also be noticed during low speed acceleration or deceleration, typically in light turns of the steering wheel.
The following are characteristics of this noise:
| • | This noise is very random. |
| • | This noise is independent of the steering wheel angle and independent of the bumpiness of the road. |
| • | This noise is a low frequency dull one and can be felt in your feet. |
| • | This noise can normally be heard from the driver seat. |
| • | This noise can be felt upon touching the steering gear from outside of the vehicle. |
Note that you might also notice a slight scrub-type noise when turning the wheel back and forth. This type of noise is considered normal and repairs will not eliminate it.
Cause
This condition may be caused by inadequate lubrication of the steering intermediate shaft.
Correction
Refer to Corporate Bulletin Number 04-03-08-006B.
