Power Steering Judder
(Supersedes Service Bulletin 89-033, dated October 20, 1989)
SYMPTOM
A judder felt in the steering wheel and/or a moaning noise heard from the power steering rack, usually on hard turns. It's sometimes more noticeable
when the front of the car is pointed downhill or when the engine is cold.
CORRECTIVE ACTION
Replace the power steering control valve with the new part listed under PARTS INFORMATION.
1.
Remove the control valve from the power steering valve body assembly using the procedure outlined in the Power Steering section of the
appropriate service manual.
2.
Check the identification mark on the end of the control valve, then replace the valve with a new one of the same size.
NOTE:
^
If you can't read the identification mark, install a "Y" valve.
^
If the valve body is scored, the valve body, control valve, and cut-off valve must be replaced as a set.
3.
Reassemble and reinstall the control valve. Refill the power steering reservoir to the upper level.
4.
Before test driving the car, start the engine and, with the car stationary and on the ground, turn the steering wheel lock-to-lock several times.
5.
Recheck the reservoir level and add fluid as necessary.
6.
Test drive the car, making both left and right turns at slow speeds.
