N-107-854-01 Genuine VW/Audi Front Subframe Bolt - M12 x 1.5 x 95

Genuine VW/Audi front subframe mounting bolt, part number N-107-854-01. This original collared hex fastener secures the front subframe to the vehicle at the assigned mounting positions on the configurations below. It is supplied individually for subframe removal, refitting or related repair work.

Technical details

• Original part number: N-107-854-01 / N10785401.
• Published nominal size: M12 x 1.5 x 95.
• External hex head with the pictured collar and washer arrangement.
• Specified application: front subframe-to-vehicle attachment.
• Cataloged position: outer uppermost front subframe attachment. This listing supplies one bolt.
• Subframe, brackets and other mounting fasteners are separate.

The front subframe supports and locates several chassis components in the vehicle. Correct mounting hardware helps keep the assembly seated in its prescribed position. Several bolt lengths and mounting arrangements can be used across the same subframe, so the original number and exact attachment point are essential selection details.

This M12 bolt is not a complete subframe hardware kit. Check every mounting position separately and obtain the additional bolts, brackets or locating hardware required by the repair procedure.

Common reasons to replace

Replacement is commonly required when the subframe connection has been released during suspension, steering or drivetrain service and the factory procedure specifies new mounting hardware. Replace damaged threads, a rounded hex head, deformation, missing hardware or corrosion affecting reliable installation.

Earlier repairs may leave an incorrect substitute bolt or a reused fastener at a position that requires replacement. Inspect the complete attachment arrangement before reinstalling the subframe.

Clunks, steering changes or alignment problems require diagnosis of the suspension, steering and mounting components. A new bolt cannot repair a bent subframe, damaged body mounting point, worn control-arm bushing or defective steering component. Repair those faults and inspect the mating threads and contact surfaces before final assembly.

Installation and service notes

Follow the factory front subframe procedure for the exact vehicle. Support the subframe and any affected powertrain components with the prescribed equipment before releasing mounting bolts. Observe the specified order for disconnecting attached suspension, steering and related components.

Preserve or establish the prescribed subframe position using the approved locating procedure. Inspect mounting faces and body threads, then install the correct hardware at each assigned position. Start the bolts by hand in undamaged threads rather than using tightening force to pull a misaligned assembly into place.

Follow the required tightening sequence, torque and additional angle for this exact attachment. Use the specified thread preparation and replace all one-time-use hardware called out by the factory procedure.

Do not transfer a tightening value from another subframe bolt, engine mount connection or M12 fastener. Different lengths and mounting positions can have different requirements. If a bolt binds or the subframe does not seat normally, inspect component alignment and hardware selection before continuing.

Complete the prescribed steering, suspension and alignment checks after service. Confirm that all affected components and lines have their required clearance and that the full mounting arrangement is secure. This listing supplies one original bolt; order the quantity needed for the repair.

Fitment

Confirm the original bolt number and front subframe attachment before ordering. One bolt supplied.
