N-101-277-07 Genuine VW/Audi Front Strut Mount Bolt

Genuine VW/Audi front strut mount bolt, part number N-101-277-07. This original fastener secures the specified front upper strut mount to the vehicle body. It is supplied individually for suspension service involving the original upper mounting arrangement.

Technical details

• Original number: N-101-277-07 / N10127707.
• External hex head with the pictured broad bearing flange.
• Assigned connection: front upper strut mount to vehicle body.
• Published application quantity: three per side, six for both front mounts.
• One bolt supplied. Strut mount, bearing, shock absorber and other fasteners are separate.

The upper mounting bolts clamp the strut mount against its intended body attachment points. The correct fastener must match the original mounting position so that its thread engagement and bearing surface suit the joint. A visually similar bolt can have a different length or head arrangement.

This fastener is separate from the central piston-rod nut and the lower strut-to-knuckle pinch bolt. Those connections have different jobs and service requirements. Match the original number at the upper mount-to-body connection rather than selecting hardware solely from the general suspension layout.

Common reasons to replace

Replace a bolt with damaged threads, a rounded hex drive, distortion or corrosion that compromises reliable service. Missing or incorrect mounting hardware should be corrected when the upper strut assembly is inspected.

Upper strut mount or bearing replacement, shock absorber service and other work requiring removal of the mounting bolts can provide an opportunity to inspect their condition. Renew the bolts whenever the factory procedure requires replacement after removal.

Noise or movement near the upper strut mounting area requires diagnosis of the complete assembly. A new bolt cannot repair a worn bearing, damaged rubber mount, stripped mounting threads, a failed damper or a damaged body attachment point. Replace hardware as part of correcting the identified fault.

Installation and service notes

Follow the factory procedure for the vehicle's original front strut arrangement. Support the assembly as required before removing its attachment hardware. Observe the procedure's precautions for components under spring load and use the prescribed service equipment.

Inspect the mounting surfaces, thread condition and upper mount orientation before assembly. Install the correct fasteners in their assigned holes and start them by hand without cross-threading. Do not use the bolt to pull a misaligned assembly into position.

Use a correctly sized socket fully seated on the hex head. Apply the specified tightening sequence and torque or angle requirement for this exact upper mounting connection. Do not transfer a tightening value from the central strut nut or lower pinch bolt.

Follow the factory instructions for thread preparation and hardware renewal. Additional washers, thread treatments or replacement fasteners should be used only when required by the applicable procedure. An aftermarket upper mount can have its own installation requirements; confirm hardware selection before fitting it.

Order the quantity required for the work being completed. This listing supplies one bolt rather than a six-piece vehicle set. Inspect the remaining upper mounting hardware and replace any other parts required by the service procedure.

After assembly, complete the prescribed suspension checks and confirm the attachment is correctly seated. Check wheel alignment whenever required by the work performed. Diagnose any remaining noise or movement rather than attempting to correct it by overtightening the mounting hardware.

Fitment

Confirm N10127707 at the upper mount-to-body connection. One bolt supplied.
