OVERVIEW
Genuine stabilizer-link attachment nut
The N-901-838-04 Genuine VW/Audi self-locking hexagon collar nut secures the assigned stabilizer-link connection on the configurations listed below. The M8 thread and collar must match the original bolt and attachment.
The factory Taos and Tiguan procedure identifies this nut at the rear link-to-lower-control-arm connection and calls for replacement after removal. Similar suspension joints can use different nuts even on the same vehicle.
Technical details
- Complete factory number: N-901-838-04.
- Nominal factory specification: M8 thread.
- Design: self-locking hexagon collar nut.
- Quantity supplied: one individual nut.
The nominal specification describes the nut itself rather than packaged shipping dimensions. Match the complete factory number, original attachment point and head seating arrangement. Similar-looking hardware elsewhere in the same assembly can differ in length, thread size or bearing surface.
Common reasons to replace
- A nut is missing after component removal or previous service.
- The wrenching flats are damaged or rounded.
- The threads have been crossed, stripped or otherwise damaged.
- The collar or locking element is damaged.
- A previous repair used incorrect substitute hardware.
Inspect the mating bolt, link joint, bushings and control-arm attachment for damage. A new nut cannot repair worn link joints or damaged threads. Suspension knocks require diagnosis before parts are replaced.

Installation guidance
Use new hardware where required by the factory repair procedure. Support the suspension correctly and follow the specified loading position, sequence and tightening instruction for the exact joint. Replace this self-locking nut after removal; do not rely on a previously used locking insert.
Align the mating components before engaging the nut, start the threads carefully and use the correct tool for the actual drive. Follow the factory tightening instruction and sequence for the exact connection. Do not transfer torque values between different applications that happen to use the same nut number.
Confirm the link is correctly seated and has clearance through its intended movement. Follow all checks required after suspension service.
