Jeep Cherokee (XJ): Description and operation. Diagnosis and testing. Removal and installation
POWER STEERING GEAR DESCRIPTION The power steering gear is a recirculating ball type
gear with a 14:1 ratio. OPERATION The gear acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is supported
by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned the rack piston moves. The rack piston
teeth mesh with the pitman shaft. Turning the
worm shaft turns the pitman shaft, which turns the
steering linkage. CAUTION: Components attached with a nut and
cotter pin must be torqued to specification. Then if
the slot in the nut does not line up with the cotter
pin hole, tighten nut until it is aligned. Never loosen
the nut to align the cotter pin hole. POWER STEERING GEAR LEAKAGE
