What This Boot Kit Helps Address

  • Torn CV boots that expose the joint to dirt and moisture
  • Slipped boots that no longer seal the axle properly
  • Porous boot material that allows grease leakage
  • Heat-related boot deterioration on high-torque driveline systems
  • Outer CV joint contamination on Audi A4 and Audi A4 Quattro front axle applications

Installation Notes and Tips

Verify the exact axle and VIN break before ordering, since this GKN Loebro 305120 boot kit is application-specific. Match the original boot material and dimensions to the joint, especially on vehicles originally equipped with a TPE boot. This part cross-references Audi OE numbers 8E0498203A and 8E0498203D for the same application.

Quality Assurance

GKN Automotive supplies OE-quality driveline components and designs these boot kits to match the joint-specific fit required for reliable sealing. The TPE construction is selected for the heat and torque demands common in modern driveline systems, helping support professional CV joint repair on Audi A4 and Audi A4 Quattro vehicles.
