Step 12 - Attach the bottom strut mount and temporarily tighten the lower strut nut
Step 13 - Torque strut top lock nut to 20 ft-lbf
Step 14 - Torque 3 nuts on strut top mount to 47 ft-lbf
Step 15 - Install strut top mount cap and torque to 18 ft-lbf
Step 16 - Re-install upper control arm ball joint into rear axle carrier. You will need to use a jack to raise the axle carrier, and another to push the upper control arm down. For the axle carrier, put your jack under the brake caliper; for the upper control arm, I put the Lexus car jack between the coil spring stop and the upper control arm. I used a 2-1/2" U-bolt to secure the jack to the rear strut (see photo). Adjust the 2 car jacks to line up the ball joint bolt.
Torque the ball joint nut to 52 ft-lbf.
Step 17 - Torque strut lower nut to 52 ft-lbf
Step 18 - Re-install rear wheel and torque lug nuts to 76 ft-lbf
