REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
The hub bearing could be damaged if it is subjected to the vehicle weight, such as when moving the vehicle with the halfshaft removed. If it is necessary to place the vehicle weight on the hub bearing, support it with a special tool SST 09608-16041. If the vehicle is equipped with ABS, after disconnecting the half shaft from the axle hub, be careful so not to damage the sensor rotor serration on the axle shaft.
- Remove the wheel cover.
- Remove the cotter pin and lock nut cap. With the aide of an assistant depressing the brakes, remove the bearing lock nut.
- Raise and safely support the car. Remove the engine under covers and drain gear oil or transaxle fluid.
- Remove the wheel.
- On ABS models, unbolt and remove the ABS sensor from the vehicle.
- Disconnect the lower control arm to steering knuckle attaching nuts and bolts.
- Use a ball joint separator or equivalent to remove the tie rod ball joint from the steering knuckle.
- Remove the bolts holding the brake caliper bracket to the steering knuckle. Use stiff wire to suspend the caliper out of the way; do not let the caliper hang by its hose. Remove the brake disc.
- Using a puller or equivalent, push the axle from the hub.
The axle can be separated from the hub using a brass or plastic hammer some others may require the use of a puller.
- Use a slide hammer and hub nut wrench pull the halfshaft from the transaxle. Remove the halfshaft from the car. Be careful no to damage the dust cover and oil seal during removal.
- Using a flat bladed tool, remove the snapring from the inboard joint spline.
- Coat the seal lip with multi-purpose grease. Install halfshaft into transaxle. If necessary, use a long brass drift and a hammer to drive the housing ribs onto the inner joint.
Before installing the halfshaft, position the snapring opening side facing downward.
- Install the halfshaft into the wheel hub. Check that the halfshaft can not be pulled out by hand.
- Install the lower control arm to the steering knuckle. Tighten the nuts and bolts to 105 ft. lbs. (142 Nm).
- Install the tie rod end to the steering knuckle and tighten the nut to 36 ft. lbs. (49 Nm).
- Install the brake disc and caliper, then tighten the bolts.
- Install the wheel.
- Install the hub nut and washer.
- Lower the vehicle to the ground.
- Tighten the wheel lugs to 76 ft. lbs. (103 Nm). Tighten the hub nut while depressing the brake pedal to 137 ft. lbs. (186 Nm). on 1988-91 models and 152 ft. lbs. (206 Nm) on 1992-97 models.
- Install the lock nut cap and NEW cotter pin. Fill transaxle with gear oil or transaxle fluid if necessary.
- Install the ABS sensor and tighten the retaining bolts to 71 inch lbs. (8 Nm).
- Install engine cover. Check front wheel alignment.

The halfshaft assembly is a flexible unit consisting of an inner and outer Constant Velocity (CV) joint joined by an axle shaft. Care must be taken not to over-extend the joint assembly during repairs or handling. When either end of the shaft is disconnected from the car, any over-extension could result in separation of the internal components and possible joint failure.
The CV joints are protected by rubber boots or seals, designed to keep the high-temperature grease in and the road grime and water out. The most common cause of joint failure is a ripped boot (tow hooks on halfshaft when car is being towed) which allows the lubricant to leave the joint, thus causing heavy wear. The boots are exposed to road hazards all the time and should be inspected frequently. Any time a boot is found to be damaged or slit, it should be replaced immediately.
Whenever the halfshaft is held in a vise, use pieces of wood in the jaws to protect the components from damage or deformation.
- Mount the driveshaft in a vise and check that there is no play in the inboard and outboard joint.
- Make sure that the inboard joint slides smoothly in the thrust direction.
- Make sure that there is no excessive play in the radial direction of the inboard joint.
- Inspect the boots for damage (rips, punctures and cracks).
On Toyota type:
- Remove the inboard joint boot clips.
- Slide the inboard joint toward the outboard joint.
On Saginaw type:
- Using pliers, remove the boot clamps.
- Using a side cutter, cut a small boot clamp and remove it.
- With chalk or paint, matchmark the inboard joint tulip and tripod. DO NOT use a punch.
- Remove the inboard joint tulip from the driveshaft.
- Using a snap ring expander, remove the snapring from the tripod.
- Place matchmarks on the drive shaft and tripod.
- Using a brass rod and hammer, evenly drive the tripod joint off the driveshaft without hitting the joint roller.
- Remove the inboard joint boot.
- On the right side, using a screw driver, remove the clamp and dynamic damper.
- Remove the clamps and the outboard drive boot. DO NOT disassemble the outboard joint.
- Remove the dust cover from the inboard joint using a press and SST 09950-00020 or equivalent.
- Mount the outboard joint shaft in a soft jaw vise. Using a screws driver and hammer, remove the No. 2 dust deflector.
If equipped, be careful not to damage the ABS speed sensor rotor.To assemble:
- Using the SST and a press, install a new No. 2 dust deflector.
- Using a press, install the inboard joint tulip into a new dust cover.
Before installing the boot, wrap the spline end of the shaft with masking tape to prevent damage to the boot. On the right side, fix the clamp position in line with the groove of the halfshaft.
Install the tripod, on Toyota types:
- Place the beveled side of the tripod axial spline toward the outboard joint.
- Align the matchmarks placed before removal.
- Using a brass bar and hammer, tap in the tripod to the halfshaft. Do not tap the roller.
- Using a snapring expander, install a new snapring.
- Pack the outboard tulip joint and the outboard boot with about 4.2-4.6 ounces of grease on Toyota types (black) and 5.8-6.4 ounces on Saginaw types (green) that was supplied with the boot kit.
- Install the boot onto the outboard joint.
- Pack the inboard tulip joint and boot with grease that was supplied with the boot kit.
- Align the matchmarks on the tulip joint and tripod.
- Install the inboard tulip joint onto the halfshaft.
- Install the boot onto the halfshaft.
- Make sure that the boot is properly installed on the halfshaft.
- Before checking the standard length, bend the band and lock it.
- Make sure that the boot is not stretched or squashed when the driveshaft is at standard length.
