Detailed Description

CV boots are a critical sealing component in the driveline, and torn, slipped, or porous boots are common causes of CV joint failure. GKN Loebro 300500 is engineered as an exact-fit replacement boot kit for the joint it serves, helping maintain proper grease retention and protection against road debris and moisture. For BMW 525i and BMW 530i rear applications, correct boot fit and material selection are important for reliable service life.

This part cross-references BMW 33 21 09 067 812 and 33 21 1 226 033 for the same application.

What This Part Helps Address

• Split or torn CV boot material
• Grease leakage from the CV joint area
• Contamination from dirt, water, and road debris
• Noise caused by a worn or unprotected CV joint
• Premature joint wear after boot damage

Installation Notes and Tips

Verify joint-end and shaft-end dimensions before installation to confirm the correct replacement. Match the boot material to the original driveline specification; if the original driveshaft uses a TPE boot, select the matching TPE replacement instead of a rubber alternative. Clean the joint thoroughly before assembly and inspect the axle for wear before installing the new boot.
