BMW E31 Upper rear wishbone ball joint bushing (Pair) Old BMW Part number for reference: 33321138015

BMW does not provide this bushing as a standalone component; they exclusively offer a complete control arm priced at $700 each.

Due to the limited space around the bushing in the upper control arm, most alternative solutions require a specially crafted press tool to prevent damage to the rubber boot during installation.

We have designed the rubber boot to ensure it does not extend beyond the metal surface of the bushing. Consequently, you can easily press this bushing in using any standard press tool or socket without the risk of damaging the boot.

We utilized high-quality polyurethane rubber in the upgraded ball joint, which is engineered to withstand environmental elements for decades. This ball joint bushing has been developed from the ground up using premium materials to accommodate the E31 weight application and is precisely tailored to match OEM dimensions for a seamless installation.
