Lower Control Arm: Installation
NOTE:
Numbers in parenthesis refer to numbers in illustration.
Bolts (1) and (3) are torque-to-yield. See Fig 1 . NEW nuts, bolts and ball bearing washers must be installed. Install the lower arm bolts. Tighten the bolts in the sequence shown in five stages.
- Stage 1 - Tighten nut (1) to 74 ft. lbs. (100 N.m).
- Stage 2 - Tighten nut (1) an additional 60 degrees.
- Stage 3 - Tighten nut (2) to 89 ft. lbs. (120 N.m).
- Stage 4 - Tighten bolt (3) to 89 ft. lbs. (120 N.m).
- Stage 5 - Tighten bolt (3) to an additional 90 degrees. After 90 degrees, check bolt (3) torque is between 125-170 ft. lbs. (170-230 N.m).
Ensure the heat shield is installed to prevent damage to the ball joint. Install the lower arm ball joint. Install the bolt. Install wheel assembly. Tighten all fasteners to specification. See TORQUE SPECIFICATIONS .
