Upper Arm

Removal and Installation

CAUTION: Suspension fasteners are critical parts because they affect the performance of vital components and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation is necessary. Do not use a new part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. Remove the wheel and tire assembly.

2. CAUTION: Use the hex holding feature to prevent the ball studs (upper control arm, lower control arm tie-rod end and stabilizer bar links) from turning while removing and installing the nuts.

CAUTION: Do not hammer the ball studs to separate them from the wheel knuckle or stabilizer bar. Doing so can cause damage. Lightly tap the wheel knuckle or stabilizer bar to loosen the joints.

Remove and discard the upper ball joint-to-wheel knuckle nut.
^ To install, tighten to 115 Nm (85 ft. lbs.).

3. Separate the upper ball joint from the wheel knuckle.
4. Remove the shock absorber and spring assembly.





5. NOTE: If removing the RH upper arm, remove the retainer and position the heat shield aside to access the upper arm-to-frame nut.

Remove and discard the 2 upper arm-to-frame bolts.
^ To install, tighten to 155 Nm (114 ft. lbs.).

6. Remove the upper arm from the vehicle.

7. NOTE: Do not tighten the nuts until the installation procedure is complete and the weight of the vehicle is resting on the wheel and tire assemblies.

To install, reverse the removal procedure.
1 Always install new:
- Upper ball joint-to-wheel knuckle nuts.
- Upper arm-to-frame bolts.
2 Check the wheel alignment.
