Removal Procedure
Caution: When removing the rear springs, do not use a twin-post type hoist. The
swing arch tendency of the rear axle assembly when certain fasteners are removed
may cause it to slip from the hoist which may cause personal injury.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the rear tires and wheels. Refer to Wheel Removal
in Tires and Wheels.
- Use a utility stand in order to support the rear axle.
- Remove the rear axle coil springs, the spring seats and the spring
insulators. Refer to
Coil Spring Replacement
.
- Remove the backing plate. Refer to Brake Backing Plate Replacement
in Drum Brakes.
- Remove the park brake cables from the rear axle. Refer to

Installation Procedure
- Install the brake pipes and the brake hoses to the rear axle.
Refer to Brake Pipe Replacement - Rear
in Hydraulic Brakes.
- Position the rear axle under the vehicle.
- Install the control arm bolts.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: This is a prevailing torque type fastener. This fastener may be reused
ONLY if:
• | The fastener and its counterpart are clean and free from rust |
• | The fastener develops 4 N·m (37 lb in)
of torque (drag) against its counterpart prior to the fastener seating. |
If the fastener does not meet these criteria, REPLACE the fastener.
- Install the control arm nuts.
Tighten
Tighten the control arm nuts to 220 N·m (162 lb ft).
