N-104-918-02 Genuine VW/Audi Upper Control Arm Pinch Bolt

Genuine VW/Audi upper control-arm pinch bolt, part number N-104-918-02. This long original fastener retains the specified upper control arms at their steering-knuckle connection. The application table below identifies confirmed A4 configurations using the exact part number.

Technical details

• Original number: N-104-918-02 / N10491802.
• Published nominal designation: M10 x 110 x 21.
• External hex head with a long shoulder and threaded end.
• Cataloged earlier number: N10491801.
• One bolt supplied. Matching nut, control arms and steering knuckle are separate.

The upper control-arm joints must remain correctly located in the steering knuckle. This assigned pinch bolt secures their attachment in the factory arrangement. Its shoulder, overall form and mounting position differ from other suspension bolts that may share an M10 thread.

This bolt is separate from the upper control arms' inner mounting hardware and the wheel-bearing attachment bolts. Identify the actual connection and original fastener before choosing replacement parts.

Common reasons to replace

Renew the bolt during control-arm or steering-knuckle service when the factory procedure requires replacement. Replace hardware with damaged threads, deformation, a damaged hex head or corrosion that affects the mounting connection or serviceability.

A seized pinch bolt can be damaged during removal. Inspect the steering-knuckle bore and surrounding mounting surfaces after extracting old hardware. A new bolt cannot repair a cracked knuckle, an enlarged mounting hole or a damaged control-arm joint.

Suspension knocking, play or poor steering behavior requires diagnosis of the complete suspension and steering system. Determine whether the control-arm joints, bushings, knuckle or other components need repair before renewing the connection.

Installation and service notes

Follow the factory procedure for the exact control-arm and steering-knuckle arrangement. Confirm the original bolt number and inspect the correct matching nut; it is not included in this listing.

Seat the upper control-arm joints correctly and align the assigned mounting features before installing the bolt. Do not force an incorrectly positioned joint into place with the fastener or reuse damaged mounting components.

Prepare the mating surfaces and hardware as specified by the repair procedure. Thread lubrication, replacement requirements and tightening instructions affect the connection; do not apply a generic lubricant or torque value solely because the bolt is M10.

Start the matching nut by hand on undamaged threads and tighten using the specified torque and any required additional angle. Use the prescribed sequence and vehicle support conditions for the actual repair.

If the bolt cannot be inserted or seated normally, check alignment and the condition of the knuckle bore before proceeding. Inspect the completed attachment and perform any required suspension, steering and alignment checks after service.

This listing supplies one original pinch bolt. It does not include a complete suspension hardware kit or replacement control arms. Select the repair quantity and separate nut according to the actual assembly.

Fitment

Confirm the original pinch-bolt number and exact upper control-arm connection before ordering. One bolt supplied.
