Technical details

• Original number: N-912-312-01 / N91231201.
• Published nominal size: M10 x 30.
• External hex head with washer arrangement, as pictured.
• Application: front subframe rear mounting bracket attachment.
• One-time-use fastener; renew after removal as prescribed.
• Bracket, subframe and other mounting bolts are separate.

The rear bracket is part of the front subframe mounting arrangement. This bolt belongs to the bracket connection, while other positions use different subframe, sway-bar or engine-mount fasteners. Match each original part number to its designated position.

The correct bolt length and seating arrangement are necessary for the prescribed connection. Selecting by thread diameter alone can place incorrect hardware in a mounting point, even when the bolt appears to engage normally.

Common reasons to replace

Renew this hardware when removing the specified rear mounting brackets during subframe service or repairs that require their removal. The published application identifies this as one-time-use hardware, so removed bolts should be replaced rather than judged suitable by appearance.

Replace missing bolts and any with stripped threads, a rounded hex head, deformation or corrosion that prevents proper installation. Check all required mounting positions, especially where previous work may have introduced a different length or fastener type.

Noise, abnormal movement or alignment concerns require inspection of the complete subframe mounting arrangement. A new bolt alone cannot repair a damaged bracket, bent subframe, stripped body threads or another suspension fault. Repair the diagnosed condition before reassembly.

Installation and service notes

Follow the factory front subframe procedure for the exact vehicle. Support the subframe and related assemblies as directed before releasing their mounting connections. Record or preserve the prescribed locating arrangement during removal.

Identify the rear bracket bolt positions separately from the larger main subframe bolts and sway-bar fasteners. Inspect the bracket, seating surfaces and mating threads, then obtain the complete required quantity of original hardware for the repair.

Position the bracket correctly and start the new bolts by hand in undamaged threads. Do not tighten a fastener to pull a misaligned mounting point into place or overcome abnormal resistance. Ensure the subframe and bracket are located as the repair procedure requires.

Engage the correct socket fully on the external hex head. Follow the factory tightening sequence, torque and any specified angle stage for this attachment. Observe thread preparation and hardware renewal requirements rather than applying a general M10 torque value.

If an aftermarket brace or locating kit is fitted, confirm its verified mounting instructions and hardware requirements for the actual arrangement. This listing supplies original bracket hardware and does not establish compatibility with every modified subframe setup.

After assembly, complete the prescribed checks for all disturbed suspension and steering connections. Perform any required alignment or calibration procedure associated with the repair. One bolt is supplied; order the quantity required for the mounting positions being serviced.

Fitment
