Honda 51460-S30-003 Arm Assembly, Left Front (Upper)

To remove and install the upper arm, do not disassemble it; if the ball joint or bushings are faulty, or if the upper arm is damaged, replace the entire upper arm. Begin by safely raising and supporting the vehicle, then remove the front wheels and support the lower control arm assembly with a floor jack. Use needle nose pliers to remove and discard the cotter pin from the ball joint, followed by removing the castle nut. Separate the upper ball joint from the steering knuckle with a ball joint separator tool, then remove the self-locking nuts from the upper arm anchor bolts and take the upper arm out of the vehicle. For installation, use new self-locking nuts for the upper arm and strut, install the upper control arm assembly into the strut tower, and connect the upper ball joint. After installing the front wheels, lower the vehicle and torque the upper control arm nuts to 47 ft. lbs. (65 Nm) and the castle nut to 32 ft. lbs. (44 Nm), tightening it just enough to install a new cotter pin. Finally, tighten the wheel nuts to 80 ft. lbs. (108 Nm) and check the vehicle's front end alignment.

Tighten the control arm retainers, with the front flange bolt at 76 ft. lbs. (103 Nm) and the rear bushing bolts at 40 ft. lbs. (54 Nm).

Torque the upper control arm nuts to 47 ft. lbs. and the castle nut to 32 ft. lbs., ensuring to lighten it just enough to install a new cotter pin.

Raise and support the vehicle, remove the rear wheels, and use a floor jack under the lower control arm spring perch.
