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.
Important: Place the vehicle lift pads where they will not obstruct the removal of the
rear axle control arm bolts.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General
Information.
- Remove the rear tires and wheels. Refer to
Tire and Wheel Removal and Installation
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

Installation Procedure
- Install the brake pipes to the rear axle. Refer
to
Brake Pipe Replacement
in Hydraulic Brakes.
- Position the rear axle under the vehicle.
- Install the control arms to 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).
