Detailed Product Overview

CV boots are a wear item that protect the constant velocity joint from dirt, moisture, and grease loss. When a boot tears, slips, or becomes porous, the joint can be exposed to contamination that accelerates wear. GKN Loebro 300516 is engineered as a direct-fit replacement for specific inner CV joint applications on Audi and Volkswagen driveline systems, with the correct rubber material and dimensions for reliable sealing. This part cross-references Audi/VW OE numbers 431498201D and 443498201B for the same application.

What This Part Helps Address

  • Torn or split inner CV joint boots
  • Grease leakage around the CV joint
  • Contamination from road debris and moisture
  • Boot fitment issues caused by incorrect diameter or material
  • Noise or vibration related to a damaged boot that allowed joint wear

Installation Notes and Tips

Confirm the joint end and shaft end dimensions before installation, and match the boot material to the original driveline specification. For vehicles such as the Audi A4, Audi A6 Quattro, and Volkswagen Passat, verify the exact position listed in the fitment data, including front inner, rear inner, rear right inner, rear left inner, front right inner, and front left inner applications. Clean the joint thoroughly before fitting the new boot, and inspect the CV joint for wear before reassembly.

Quality Assurance
