Installation Notes and Tips

Confirm the original boot style and dimensions before installation, especially on vehicles that use a specific joint design or cap. GKN notes that exact fit and correct material selection are important for reliable protection; if the original driveshaft uses a TPE boot, match it with the corresponding TPE replacement boot kit instead of substituting another material.

For Volkswagen Jetta, Golf, and Passat applications, verify the front left inner position and any VIN or boot-cap notes before ordering. The part number 300488 should be matched to the joint specification, not just the vehicle model.
