OE-Style CV Boot Kit for BMW X5

Restore protection at the CV joint with this GKN Loebro CV Joint Boot Kit, part number 305538. Built with TPE material and exact-fit dimensions, it is designed for BMW X5 front outer axle positions where a damaged boot can quickly lead to joint contamination and wear.

Key Features

  • OE-quality TPE boot kit from GKN Loebro
  • Solid black boot construction
  • Thermo plastic elastomer material rated for high operating heat
  • Exact-fit design for the joint end and shaft end dimensions
  • Compatible with front right outer and front left outer BMW X5 applications
  • Cross-reference: BMW 31607565316

Product Details

Part number 305538 is a GKN Loebro CV joint boot kit engineered for driveline service where the original boot has torn, slipped, or become porous. The TPE construction matches the type commonly used on modern driveline assemblies because it handles elevated joint temperatures while maintaining a secure seal around the CV joint. This matters on BMW X5 front axle service, where the correct boot fit is critical to keeping grease in and road debris out. If your vehicle uses a factory TPE boot, matching the replacement material and dimensions is important for proper repair.

What This Part Helps Address

  • Torn CV boots that expose the joint to dirt and moisture
  • Slipped boots that no longer seal correctly
  • Porous boots that allow grease loss over time
  • Noise or vibration caused by contaminated CV joint components
  • Preventive repair after boot damage is found during inspection

Installation Notes

Verify the joint end inside diameter of 3.779 inches and shaft end inside diameter of 1.082 inches before installation. This boot is a solid, non-vented TPE design with one rib, so matching the original application is important for a proper seal. Professional installation is recommended for BMW X5 front right outer and front left outer service, especially when replacing a damaged boot before joint wear progresses.

Quality Assurance

GKN Automotive supplies OE-quality driveline components and boot kits for exact-fit repair applications. Part number 305538 is built to the same application-focused standards expected for BMW X5 driveline service, with material selection and dimensions intended to match the original boot design.
