POWER STEERING GEAR NOISE
Certain 1986-1987 Comanche trucks may have a groaning sound, hissing, or whistling noise through the steering column. A redesigned intermediate
steering shaft (A) (between the steering column and the power steering gear) is now being used in production to correct this condition. It is now available
as a service part.
This new shaft will reduce the noise being emitted into the passenger compartment.
To identify the old style shaft (B), look for a series of indentations (C) around the damper cover at the steering column end (D) of the shaft.
If this noise is reported, inspect the intermediate steering shaft. If the old style is used, replace the shaft.
Procedure
Removal
1.
Raise the vehicle.
2.
Remove the front skid plate (F), if equipped.
