What It Helps Address

• Road debris and moisture entering the joint
• Boot fitment issues caused by incorrect dimensions

Installation Notes and Tips

Confirm the original boot material before ordering, especially on applications that use rubber rather than TPE. Match the joint end and shaft end dimensions to the original part, and verify the rear outer position before installation. The kit is intended for professional repair work on the CV joint area, so careful cleaning of the joint and correct seating of the boot are important for a reliable seal.
