BMW supplies the upper rear wishbone ball joint bushing only as part of the complete control arm assembly. This upgraded standalone bushing offers an alternative to replacing the entire arm and corresponds to BMW reference 33321138015.

Designed for the BMW E31 upper rear control arm, the ball joint bushing is made from high-quality polyurethane rubber to withstand environmental exposure and the weight demands of the E31. It is manufactured to OEM dimensions for the intended fitment.

The limited space around the upper control arm bushing can make installation difficult with some designs. This bushing has a rubber boot that sits flush with its metal surface, allowing it to be pressed in with a standard press tool or socket. The design helps avoid boot damage without requiring a specially made press tool. In UK parts terminology, it may also be described as an upper rear wishbone bush.
