REMOVAL & INSTALLATION
See Figures 1 and 2
Some models use a spindle pin instead of traditional ball joint assemblies. If your van is equipped with these components, refer to the following procedures for removal and installation of the pins and bushings.
- Jack up the front of the van and safely support it with jackstands.
- Remove the wheels.
- Remove the front brake caliper assembly and hold it out of the way with a piece of wire. Do not disconnect the brake line.
- Remove the brake rotor from the spindle.
- Remove the inner bearing cone and seal. Discard the seal, as you'll be fitting a new one during installation.
- Remove the brake dust shield.
- Disconnect the steering linkage from the spindle arm by removing the cotter pin and nut, then using a tie rod end removal tool.
- On motorhome and commercial stripped chassis models, disconnect the drag link from the steering arm using a tie rod end removal tool.
- Remove the nuts and lockwasher from the lock pin, then remove the lock pin.
- Remove the spindle pin plugs, then drive the spindle out from the top of the axle.
- Remove the spindle and thrust bearing.
- Remove the pin seal.
Always use new cotter pins. When aligning the cotter pin holes, never back off the nut; always advance the nut until the holes align.
- Make sure that the spindle pin holes are clean and free from burrs and nicks.
- Lightly coat the bore with chassis lube.
- Install a new spindle pin seal with the metal backing facing upwards towards the bushing into the spindle by gently pushing it into position.
- Install a new lower thrust bearing with the lip facing down towards the lower bushing. Press the bearing in until it is firmly seated against the surface of the spindle.
- Lightly coat the bushing surfaces with grease and position the spindle on the axle.
- Install the spindle pin with the T which is stamped on one end at the top and the notch in the pin is aligned with the lock pin hole in the axle.
- Insert the pin through the bushings and axle from the top until the spindle pin notch and axle lock pin hole are in line.
- Install the lock pin with the threads pointing forward and the wedge groove facing the spindle pin notch.
- Drive the lock pin into position and install the lockwasher and nut. Tighten the nut to 40-60 ft. lbs. (54-81 Nm).
- Install the spindle pin plugs into the threads at the top and bottom of the spindle and tighten the plugs to 35-50 ft. lbs. (48-67 Nm).
- Lubricate the spindle pins and bushings with chassis lube through both fittings until grease is visible seeping past the upper seal and thrust bearing slip joint. If grease does not appear at the top and bottom points, the spindle is installed incorrectly and rapid deterioration of the spindle components will result.
- Install the brake dust shield.
- Pack the inner and outer bearing cone with a quality wheel bearing grease by hand, working the grease through the cage behind the roller.
- Install the inner bearing cone and seal. Install the hub and rotor on the spindle.
- Install the outer bearing cone, washer, and nut. Adjust the bearing end-play and install the nut retainer, cotter pin and dust cap.
- Install the brake caliper. connect the steering linkage to the spindle. Tighten the nut to 70-100 ft. lbs. (95-135 Nm) and advance the nut as far necessary to install the cotter pin.
- Install the wheels. Lower the van and adjust toe if necessary.
