OVERVIEW
Protect the assigned inner CV joint from nearby exhaust heat
1K0-407-721-A is the Genuine VW/Audi formed metal shield for the specified right-hand inner drive-joint area. The shaped panel mounts in the original location between the joint assembly and nearby heat sources.
The factory shield creates a barrier at a closely packaged driveline location. Correct shape, bracket engagement and clearance matter: a bent or incorrectly installed shield can contact rotating parts or transmit vibration.
Technical details
- Complete factory number: 1K0-407-721-A.
- Factory specification: right-hand inner CV joint heat shield; complete revision A.
- Design: formed metal panel with application-specific mounting holes and clearance profile.
- Quantity supplied: one individual heat shield.
This listing supplies the shield only. Axle shaft, CV joint, boot, grease, mounting bracket and separate fasteners are not included. A right-hand shield is not interchangeable with a differently shaped shield simply because the hole spacing appears similar.
Common reasons to replace
- The original shield is missing after driveline work.
- Corrosion or a crack has weakened an attachment point.
- The shield is bent and cannot maintain its required clearance.
- Diagnosis traces a metallic rattle to a loose or damaged shield.
Inspect the mounting bracket, fasteners, CV boot and nearby exhaust components. Repair the cause of contact or looseness. A torn boot or worn CV joint requires its own repair; replacing the shield does not restore a damaged joint.

Installation guidance
Work with the exhaust cool and support the vehicle using the prescribed lifting points. Fit the shield in its original orientation and use the vehicle-specific fasteners and torque procedure. Keep the panel clear of the axle, boot, exhaust and other moving components.
Check attachment security and clearances through the applicable steering and suspension movement. Confirm that there is no contact or rattle during the required road test.
