Detailed Description

This CV joint boot kit is intended for driveline service where the original boot has failed and the joint needs protection restored. GKN Loebro 300486 is engineered for the front inner CV joint on Audi A4 Quattro models from 1996 through 1999, with fitment matched to the application rather than a universal size. The rubber material and solid construction help maintain a proper seal around the joint and shaft.

GKN Automotive notes that boot damage is a common cause of CV joint failure, especially when boots are torn, porous, or have slipped. This replacement boot kit follows the application-specific approach needed for a reliable repair on Audi A4 Quattro driveline components. This part cross-references Audi OE number 443498201A for the same application.

What It Helps Repair

• Torn CV boot conditions that expose the joint to dirt and moisture
• Grease leakage from a damaged front inner boot
• Boot slippage that can lead to joint contamination
• Wear caused by porous or cracked rubber boots
• Service needs on the front inner driveline of Audi A4 Quattro models

Installation Notes and Tips

Confirm the joint end and shaft end dimensions before installation, and match the replacement boot to the original application. For Audi A4 Quattro front inner service, clean the joint thoroughly before reassembly and inspect the CV joint for wear or contamination before installing the new boot. Use the correct boot style and material for the driveline design; if the original driveshaft uses a TPE boot, select the matching TPE replacement instead of a rubber alternative.
