Key Features

• OE-quality CV joint boot kit from GKN Automotive
• TPE thermoplastic elastomer boot material
• Solid boot design with black finish
• Built for front inner BMW axle applications
• Exact-fit replacement focus for BMW X5 and BMW X6 driveline service
• Part number 305739 for catalog and cross-reference use

Detailed Description

GKN Loebro 305739 is a replacement CV joint boot kit engineered for the joint-specific fit required on BMW driveline assemblies. The boot dimensions are 2.669 inches at the joint end and 1.001 inches at the shaft end, with a single rib profile and no venting. Because the original driveshaft uses TPE, matching the same material type is important for maintaining the intended heat resistance and sealing performance. This part cross-references BMW 31607545107 for the same application.

Compatible With BMW X5 and BMW X6 front inner axle positions, this boot kit supports repair of the CV joint area without changing the joint itself when the boot is the failed component. Use part number 305739 when searching for the correct OE-style replacement for BMW X5 and BMW X6 driveline service.

What It Helps Repair

• Torn CV boots that expose the joint to dirt and moisture
• Slipped boots that no longer seal the axle properly
• Porous or cracked boots that allow grease loss
• Noise or vibration caused by contaminated CV joint grease
• Preventable joint wear from damaged boot sealing

Installation Notes and Tips

Verify the original boot material before ordering; if the factory driveshaft uses TPE, select the matching TPE replacement. Confirm the joint end and shaft end dimensions, along with the front right inner or front left inner position, before installation. Clean the joint area thoroughly and inspect the CV joint for wear or contamination before fitting the new boot. Follow the vehicle service procedure for clamp and fastener installation.
