OVERVIEW
Genuine VW/Audi tie rod end retaining bolt, part number N-906-289-02. This original M8 x 25 fastener secures the outer tie rod end at its specified spindle attachment on the configurations below. One bolt is supplied.
Technical details
- Original number: N-906-289-02 / N90628902.
- Published nominal size: M8 x 25.
- External hex head with an attached washer; the archive image shows a blue patch on the threads.
- Assigned application: outer tie rod end-to-spindle retaining hardware.
- Tie rod end, separate lock/pinch bolt, nuts and steering components are separate.
The outer tie rod transfers steering motion to the wheel assembly. Its mounting hardware retains the joint in the intended attachment arrangement. Correct fastener selection and installation matter for the complete steering connection.
This M8 retaining bolt is distinct from the separate M10 tie rod lock bolt and the nut used to adjust or lock the tie rod connection. Match the original number at the actual position rather than substituting hardware by appearance or nominal diameter.
Common reasons to replace
Inspect this bolt during outer tie rod or steering knuckle service. Replace missing hardware, damaged threads, rounded wrenching flats, deformation or corrosion that compromises installation. Renew removed hardware whenever the applicable factory procedure requires replacement.
Earlier repairs may leave an incorrect bolt or damage the retaining connection. Check the complete mounting arrangement and obtain each required fastener before reassembly. A bolt that starts in the thread is not necessarily correct for the assigned position.
Steering looseness, knocking, abnormal tire wear or unstable tracking requires diagnosis of the tie rods, joints, knuckle, suspension and alignment. A new bolt cannot repair a worn ball joint, damaged joint seat or stripped mating threads. Correct the diagnosed defect before completing the steering attachment.
Installation and service notes
Follow the factory steering procedure for the exact vehicle. Support the vehicle at its prescribed lifting points and use the approved method to release and install the joint. Protect the tie rod boot and surrounding components while working on the attachment.
Inspect the spindle connection, mating threads and tie rod end. Position the joint as specified before starting the retaining bolt by hand. Do not use the bolt to force a misaligned joint or damaged attachment into place.
Use the correct hex tool and follow the factory tightening sequence, torque and any additional angle for this M8 position. Follow the specified thread preparation and new-hardware requirements. The visible thread patch does not establish a chemical specification or authorize adding an unapproved compound.
Do not transfer tightening values from the separate tie rod lock bolt, adjustment nut or another M8 steering fastener. Each component has its own installation requirement. Replace associated hardware where the factory instructions call for it.
After assembly, confirm the joint is seated, the required fasteners are installed and the boot is undamaged. Complete the prescribed steering and alignment checks after tie rod work. Preserve or restore the specified adjustment rather than estimating alignment from the old fastener position.
This listing supplies one original retaining bolt. Select the tie rod end and other attachment hardware separately for the repair.
