Detailed Description

This GKN Loebro CV joint boot kit is engineered for vehicles that originally use a TPE boot, where material match and exact fit are critical to long-term joint protection. Modern drivetrains generate significant heat and torque, so the boot material must hold up under demanding operating conditions. GKN Automotive supplies this replacement as a direct-fit solution for front-position Land Rover applications, including Land Rover LR4, Land Rover LR2, Land Rover LR3, and Range Rover Sport. If you are replacing a damaged boot on a Land Rover LR4 front axle or servicing a Land Rover LR3 front CV joint, part number 305637 is the correct OE-style choice for the specified applications.

This part cross-references LR003160 and TDR500110 for the same application.

What It Helps Fix

• Torn CV joint boots that expose the joint to dirt and moisture
• Slipped boots that no longer seal the joint properly
• Porous or cracked boots caused by age and heat
• Grease loss from a compromised front CV joint boot
• Noise and wear that can follow contamination of the CV joint

Installation Notes and Tips

Confirm the original boot material before ordering; if the driveshaft uses a TPE boot from the factory, match it with the correct GKN replacement. Verify joint-end and shaft-end dimensions, rib count, and front-position fitment before installation. Clean the joint thoroughly during service and inspect for wear before fitting the new boot. For Land Rover LR2, LR3, LR4, and Range Rover Sport applications, use the VIN and engine notes listed for exact vehicle matching. Part number 305637 should be checked against the original boot specification before assembly.
