OVERVIEW
Genuine VW/Audi rear shock absorber mount nut, part number N-103-041-02. This original self-locking hex nut is cataloged as the top nut for the specified rear shock assembly. It supplies the correct replacement hardware for an original attachment using this exact part number.
Technical details
- Original part number: N-103-041-02 / N10304102.
- Published nominal thread size: M10 x 1.
- Self-locking hex nut, supplied individually.
- Rear shock absorber top attachment on the listed configurations.
- Earlier cataloged number: N10304101.
- Shock absorber, upper mount, protective cap and mounting bolts are separate.
The shock absorber damps suspension movement, while its mount and attachment hardware retain the assembly at the specified connection. This nut provides fastening hardware; it does not provide the damping function or replace the mount itself.
The M10 x 1 specification identifies a fine-thread connection. A nut with the same nominal diameter and a different pitch is not interchangeable. Match the original hardware and shock design, especially when the vehicle has aftermarket dampers or modified suspension equipment.
Common reasons to replace
Renew the nut when replacing a rear shock or mount if the applicable repair instructions require fresh self-locking hardware. Replace a missing nut or one with damaged threads, rounded drive surfaces, deformation or corrosion affecting its condition.
Shock or mount service can expose previously damaged hardware. Inspect the mating shock thread, mount seating surfaces and any associated washers or spacers before assembly. A nut that will not start normally can indicate a thread mismatch or damaged mating component.
Rear suspension knocks, excessive movement or poor damping require inspection of the shock, mount, bushings and surrounding suspension. Installing a new nut alone will not repair a leaking damper, deteriorated mount, damaged piston rod or loose mounting structure.
Installation and service notes
Use the factory procedure to support the vehicle and remove the shock assembly. Confirm the original nut number and suspension equipment before dismantling the connection. Keep the mount components in their prescribed order.
Start the correct nut by hand on clean, undamaged threads. Follow the specified counter-holding method and tightening sequence for the actual shock and mount. Do not grip a finished shock rod with tools that can damage its surface.
Use the factory tightening specification or the instructions for an approved replacement damper. Do not infer torque from the M10 x 1 size or use a value from a lower shock bolt, control arm or another chassis.
Follow the procedure's replacement requirements for self-locking hardware and use thread treatments only when directed. If tightening is abnormal, inspect thread engagement and component seating rather than applying excessive force.
After assembly, check the mount position and complete the prescribed suspension inspection. This listing supplies one nut; it is not a complete shock installation kit or a pair of mounting assemblies.
