To remove and install the upper control arm assembly, first raise and support the vehicle safely, then remove the front wheels and properly support the lower control arm assemblies. Next, take off the self-locking nuts, upper control arm bolts, and upper control anchor bolts, and separate the upper
Ball Joint using a suitable ball joint separator tool. Place the upper control arm assembly into a holding fixture and drive out the upper arm bushing. For installation, drive the new upper arm bushing into the upper arm anchor, ensuring that on Civic and CRX models, 0.3543 inches (9 mm) protrudes from each side of the anchor bolt, while on Accord models, the leading edges should be flush with the anchor bolt. Install the upper control arm assembly and the upper arm bolts, then tighten the self-locking nuts, ensuring the upper arm anchor bolt aligns with the mark on the upper arm. Tighten the upper arm nuts to 47 ft. lbs. (65 Nm), the self-locking nuts on the control arm bolts to 22 ft. lbs. (30 Nm), and the upper ball joint pin nut to 12 ft. lbs. (44 Nm). Finally, reinstall the remaining components in the reverse order of removal.
