REMOVAL & INSTALLATION
See Figures 1 and 2
- Raise and support the front end on jackstands.
- Remove the wheels.
- Dismount the caliper and suspend it out of the way without disconnecting the brake lines.
- Remove the hub/rotor assembly.
- Unbolt the splash shield and discard the old gasket.
- Using a ball joint separator, disconnect the tie rod end from the knuckle.
- Position a floor jack under the lower control arm, near the spring seat. Raise the jack until it just takes up the weight of the suspension, compressing the spring. Safety-chain the coil spring to the lower arm.
- Remove the upper and lower ball joint nut.
- Using tool J-23742, or equivalent, break loose the upper ball joint from the knuckle.
- Raise the upper control arm just enough to disconnect the ball joint.
- Using the afore-mentioned tool, break loose the lower ball joint.
- Lift the knuckle off of the lower ball joint.
- Inspect and clean the ball stud bores in the knuckle. Make sure that there are no cracks or burrs. If the knuckle is damaged in any way, replace it.
- Check the spindle for wear, heat discoloration or damage. If at all damaged, replace it.
Installation is the reverse of removal but please note the following important steps.
- Maneuver the knuckle onto both ball joints and tighten the nuts to specifications.
- Install a new splash shield gasket and tighten the shield bolts to 10 ft. lbs. (14 Nm) on R-series vehicles. On C-series vehicles, tighten the bolts to 12 ft. lbs. (16 Nm) on 1988-90 models; 19 ft. lbs. (26 Nm) on 1991-98 models.
