Honda 52390-SS0-003 Arm Assembly, Right Rear (Upper)

To work on the Prelude models' rear wheels, carefully lift the car, prop it up, and take off the rear wheels. Then place a jack under the control arm and knuckle so they stay in position. Take out the upper ball joint from the knuckle by using a ball joint separator tool, push away the trunk panel, and unscrew the two strut-stabilitizer nuts. Pull off the nuts holding the upper arm bolts in place and remove the arm from the vehicle. Keep the arm together when taking it out - you must replace everything if the ball joint fails, the bushings wear out, or the arm gets damaged. When reinstalling, first install the upper arm and strut together using new self-locking nuts on the upper arm. Place the upper control arm assembly into the strut tower, fit the upper ball joint, and finish by installing the rear wheels while lowering the entire car. Lower the vehicle onto all four wheels, finding the right amount of tension on the upper control arm nuts. Then fix the cast nut to 32 ft. pounds torque, relax enough to put in a fresh cotter pin. After tightening wheel nuts to the required 80 ft. lbs. force, replace the trunk trim and adjust the vehicle to correct wheel alignment at the rear. You need to replace the entire control arm when the bushings in the upper part of the control arm become worn or damaged.

New self-locking nuts for the upper arm and strut are required for installation.
