Rear Upper Control Arm Assembly (RH/LH) for Toyota Suspension

This rear upper control arm assembly is a key suspension link that keeps the rear wheel aligned while the vehicle moves over bumps, braking, and cornering. It’s needed when the original arm is bent, corroded, the bushing is torn, or the ball joint develops play—common after pothole hits or long mileage. A healthy arm helps your Toyota track straight, reduces tire wear, and restores stable handling.

How It Works ⚙️

The arm mounts between the rear knuckle and the chassis. Its bushings absorb vibration and allow controlled movement, while the joint keeps the wheel position correct through suspension travel. By controlling camber/toe behavior, it supports smooth ride comfort and predictable rear-end grip.

What Happens If It’s Worn or Broken ❗

A damaged control arm can cause clunking noises, wandering on the highway, uneven or rapid tire wear, and poor rear stability in turns. In severe cases, alignment can’t be set properly, braking feel may worsen, and the vehicle may feel unsafe at speed.
