Rolls-Royce Phantom Control Arms & Ball Joints

Upper control arms, lower control arm sets and upper and lower ball joints for the Rolls-Royce Phantom sedan, extended wheelbase sedan, Coupe and Drophead Coupe built from 2003 to 2016. The upper arms are sold as separate left and right parts, the lower arms come as a set for both sides, and the ball joints are sold on their own, so a single worn joint does not always mean replacing a complete arm.

How is the Phantom front suspension laid out?

The Phantom uses a double-wishbone front suspension, with an upper and a lower control arm on each side holding the wheel carrier, and air springs carrying the weight of the car. The lower arm carries most of the load, while the upper arm controls the angle of the wheel as the suspension moves and the wheel steers. The ball joints connect the arms to the wheel carrier and let it pivot.

Upper or lower control arm: which one is worn?

A worn lower arm usually shows up as a heavy knock over bumps and under braking, and as vibration through the steering wheel when slowing down. A worn upper arm is more often a lighter knock or creak over uneven roads and a front end that wanders on the highway. Both cause uneven wear on the inside or outside edge of the front tires. A cracked rubber mount, or play at a ball joint when the wheel is rocked, confirms which part has failed.

When is a ball joint enough?

If the rubber mounts on the arm are sound and only the ball joint has play, replacing the joint alone restores the steering at a lower cost. If the mounts are cracked or split as well, a complete control arm is the better repair, since a new joint in a worn arm will not stop the knock.

What to know before fitting

Put the air suspension through the correct workshop procedure before lifting the car, and tighten the mounting bolts with the suspension at normal ride height so the new rubber mounts are not preloaded. On cars built with the earlier lower arms, the ball joint size differs on the current arm, so compare the old part with the new one before fitting. A four-wheel alignment and a ride height check should follow any control arm or ball joint replacement.
