OVERVIEW
Genuine VW/Audi lower rear shock securing bolt, part number N-105-008-02. This original fastener attaches the specified lower rear shock mounting point to the wheel-bearing housing. Correct attachment hardware keeps the shock connected to its designed rear suspension mounting position.
Technical details
- Original part number: N-105-008-02 / N10500802.
- Published nominal size: M14 x 1.5 x 90.
- External hex head with an integral collar.
- Original-parts catalog identifies a self-locking bolt.
- One bolt supplied; one is required at each assigned rear shock attachment.
- Shock absorber, mounting housing and remaining hardware are separate.
The rear shock controls suspension movement through its upper and lower attachments. This bolt belongs to the specified lower connection, where correct seating and hardware selection are necessary for the assembly to function as designed.
It is separate from the upper shock mounting hardware and other suspension bolts. Verify the original number at the actual rear shock position; thread diameter alone does not identify the correct replacement.
Common reasons to replace
Renew the bolt during rear shock service whenever the factory procedure requires replacement after removal. Replace missing hardware, damaged threads, a rounded head, deformation or corrosion that affects serviceability or proper installation.
Shock replacement can reveal prior tool damage, incorrectly selected hardware or a damaged mounting point. Inspect the shock eyelet, attachment housing and mating threaded hole before installing new hardware.
Rear suspension noise or abnormal damping requires diagnosis of the shocks, bushings, mounts and other rear suspension components. A new bolt cannot repair a worn shock, damaged bushing or cracked mounting housing. Identify the cause of any looseness before completing the repair.
Installation and service notes
Follow the factory procedure for the exact rear suspension configuration. Support the vehicle and suspension components as directed before releasing the shock attachment.
Match the original bolt number, nominal size and assigned mounting position. Prepare the contact surfaces and mating threads according to the repair procedure, and ensure the lower shock attachment is correctly aligned.
Start the bolt by hand into undamaged threads and confirm normal seating. Use the correct hex socket and follow the prescribed tightening specification, including any required additional angle.
Observe the specified suspension position during final tightening. Do not assume that an attachment can be tightened at full suspension droop, and do not infer torque from the M14 x 1.5 x 90 size.
Follow the factory instructions for the self-locking fastener, thread preparation and renewal. An added lubricant or substitute thread treatment can change the tightening behavior; use only the prescribed arrangement.
Inspect the completed connection and perform the applicable suspension checks after service. This listing supplies one original lower shock bolt, not a complete shock mounting kit. Select the repair quantity for the actual sides being serviced.
