OE-Style CV Boot Kit for Audi Driveline Repair

GKN Loebro 304955 is an OE-quality TPE CV joint boot kit built for precise replacement on select Audi driveline applications. It is designed for outer front CV joints where the original boot uses thermoplastic elastomer material and exact fit is critical to protecting the joint from contamination and grease loss.

Fitment and Application Details

This GKN Loebro CV joint boot kit is specified for Audi A4, Audi A5, Audi A6 Quattro, Audi A7 Quattro, Audi A8 Quattro, Audi S4, Audi S5, and Audi Q5 applications with matching TPE boot requirements. Use it for front right outer, front left outer, and front outer positions only where the original setup calls for this exact boot style. This part cross-references 8K0498203 for the same application.

The boot material matters because modern drivetrains generate significant heat and torque at the joint. GKN Automotive specifies TPE for these applications because the material handles elevated temperatures and helps maintain a reliable seal around the CV joint. If the original driveshaft uses a TPE boot, 304955 should be matched to that same design rather than substituted with a different boot type.

What This Part Helps Address

• Torn CV boot causing grease leakage
• Slipped boot that exposes the joint to dirt and moisture
• Porous or aged boot material that no longer seals properly
• Noise or vibration caused by contamination entering the CV joint
• Premature CV joint wear from loss of lubrication
