Built for Exact Fit and Material Match

This boot kit follows the OE-style TPE construction used on modern driveline assemblies to handle elevated operating temperatures and maintain a reliable seal around the joint. If you are searching for a BMW X3 front right outer CV boot kit or a BMW X3 front left outer CV boot kit, this part number is the correct OE-style service option.

Common Problems This Part Addresses

Installation Notes and Tips

Confirm the original boot material before ordering; if the factory driveshaft uses a TPE boot, match it with a TPE replacement such as GKN Loebro 305537. Verify the joint end and shaft end inside diameters before installation, and inspect the CV joint for wear or contamination before fitting the new boot. Proper seating and clamp tension are important for sealing performance on BMW X3 front axle service work.
