1988 4WD Steering Knuckles
ALL MANUFACTURERS
DESCRIPTION
Open type steering knuckles are used on all models. Open
type knuckles provide sharper turning angle, which will decrease
vehicle turning radius. Axle shafts are free floating. Depending upon
vehicle model, steering knuckles can be attached to axle housing by
either ball joints or roller bearings and king (pivot) pins.
OVERHAUL
BALL JOINT TYPE
Disassembly
1) Raise vehicle and support securely. Remove wheels. Remove
brake caliper and rotor. If equipped, remove locking hubs. See
appropriate LOCKING HUBS article in DRIVE AXLE section.
2) Disconnect tie rod end from steering knuckle. Remove
spindle nuts and lightly tap spindle with soft face hammer to free it
from steering knuckle. Pull out axle shaft assembly.
3) Clean all components with solvent and dry with compressed
air. Inspect all parts for burrs, chips, wear, flat spots or cracks.
Replace all damaged or worn parts.
NOTE: When aligning upper ball joint nut to install cotter pin,
always tighten nut to align. Never loosen nut to align holes.
Reassembly
To reassemble, reverse disassembly procedure. Torque all
fittings to specifications.
