Control Arm Bushing Replacement Lower Control Arm
Removal Procedure
Caution: Place Jackstand under front of vehicle to prevent vehicle
from falling from hoist.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assemblies. Refer to
Wheel Removal
in Tires and Wheels.
- Support the inboard end of the lower control arm with a transmission
jack. Position the brackets on the jack in order to securely hold the control
arm.
- Remove the stabilizer
link lower attachment.
- Remove the shock absorber
lower attachment.
- Remove the inboard lower
control arm nuts and bolts.
- Slowly lower the transmission jack in order to relieve the spring
pressure.
- Pull the lower control arm down in order to remove the spring.
- Lower the control arm outboard bolt, if you are removing the control
arm.
Installation Procedure
- Position the control arm
in the vehicle.
Install the outboard control arm bolt and nut.
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.
Tighten
Tighten the lower control arm outer nut to 102 N·m (75 lb ft).
- Install the spring and insulators.
Important: In order to insure proper orientation of the spring, rest the spring
(without insulators) on a flat surface. The spring will stand up straight
when resting on its lower end, but will lean or tip when resting on its
top end.
- Raise the transmission jack under the inboard end of the lower control
arm in order to slightly compress the spring.
- Insert the inboard lower control arm nuts and bolts.
- Install the shock absorber
lower attachment.
- Install the stabilizer
link lower attachment.
- Remove the transmission jack. Place the jack under the outboard
end of the lower control arm in order to bring the suspension to the suspension's
design position. The inner control arm nuts must be tightened in the design
position in order to reduce wind up in the bushings.
Tighten
• | Tighten the stabilizer link lower nut to 60 N·m (44 lb ft). |
• | Tighten the shock absorber lower nut to 102 N·m (75 lb ft). |
• | Tighten the lower control arm inner nuts to 102 N·m
(75 lb ft). |
Important: Perform a rear wheel alignment if you loosened the inner lower control
arm fasteners.
- Install the tire and wheel assemblies. Refer to
Wheel Installation
in Tires and Wheels.

Removal Procedure
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the tire and wheel assembly. Refer to
Wheel Removal
.
- Disconnect the electronic level control height sensor link.
- Disconnect the Road Sensing Suspension position sensor and bracket
from the shock tower.
- Remove the inner and outer
control arm bolts.
- Raise the control arm up over the shock tower in order to remove
the control arm from the vehicle.
Installation Procedure
- Raise the control arm
up over the shock tower in order to install the control arm in the vehicle.

installing fasteners in order to avoid damage to parts and systems.
- Install the inner
and outer control arm bolts. Place the screw jack under the outboard end of
the lower control arm in order to bring the suspension into design position.
The inner control arm nuts must be tightened in design position in order
to reduce the wind up in the bushings.
Tighten
Tighten the upper control arm inner and outer nuts to 57 N·m
(42 lb ft).
- Connect the Road Sensing Suspension position sensor bracket and
sensor.
- Connect the electronic level control height sensor link.
- Install the tire and wheel assembly. Refer to
Wheel Installation
.
- Lower the vehicle.
