1. Install the upper control arm to the frame bracket.

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: 

•	A normal shim pack will leave at least 2  threads of the bolt exposed beyond the nut.

•	If 2  threads cannot be obtained, check for a damaged control arm or related parts.

•	The difference between the front and the rear shim packs must not exceed 7.62 mm (0.30 in). The front shim pack must be at least 6.09 mm (0.24 in).

•	Always tighten the thinner shim pack nut first in order to improve the shaft to frame clamping force and torque retention.

2. Install the nuts.

Tighten
Tighten the nuts to 142 N·m (105 lb ft).

3. Connect the upper control arm to the steering knuckle. Insert the stud of the upper control arm ball joint into the steering knuckle.

Important: Maximum torque needed to align the cotter pin is 175 N·m (130 lb ft).

4. Install the nut and the cotter pin.

Tighten

•	Tighten the nuts to 122 N·m (90 lb ft).

•	Tighten the nut if needed to install the cotter pin.
