Original BMW Outer CV Boot Repair Kit for BMW E30 and E36 3 Series, E30 M3, and Z3 Roadster (1987–2000)

BMW calls part 33-21-9-067-815 a repair kit for the exterior bellows, which makes it the outer CV joint boot kit for the drive axles on E30 and E36 3 Series cars, the E30 M3, and the Z3 Roadster from 1987 to 2000. A CV boot is a flexible rubber cover. It seals the joint at the wheel end of the axle, keeping grease in and dirt, water, and debris out. BMW supplies this part as a set weighing 205 g. It has been in production since May 1994 and replaces the earlier part number 33-21-9-067-813. BMW marks the new number as exchangeable retrospectively, so it fits cars originally built with the older kit.

This Original BMW repair kit carries a 24-month parts warranty.

The position is the key choice here. This kit is for the outer boot only, the one at the wheel end of the axle. Each kit services the outer boot on one side of the car, so a car that needs both outer joints done takes two kits. The same part number covers the M20, M40, M42, and S14 engines in the E30, and the M50, M51, and M52 engines in the E36. It also covers the Z1 and the M52- and M54-powered Z3. Because one kit covers these drivetrains, you do not need to choose a version by engine.

Common Questions

How do I know an outer boot has failed?
Look for grease thrown onto the inner side of the wheel or onto the suspension behind the spindle. Clicking or popping when turning, and humming from a dry joint, can also point to boot failure.

How many kits do I need for both sides?
Two. Each kit covers one outer boot.
