OVERVIEW
Correct driveshaft hardware for the specified eight-speed application
N-106-677-01 is a Genuine VW/Audi M10 x 50 socket-head collared bolt with an internal multipoint drive. The confirmed Q7 applications below assign this bolt to the cardan-shaft assembly with the G1G eight-speed automatic transmission.
The factory catalog lists different driveshaft hardware for six-speed and eight-speed configurations. Matching diameter alone is insufficient: the original length, head design and transmission-specific flange arrangement must be retained.
Technical details
- Complete factory number: N-106-677-01.
- Factory specification: M10 x 50 mm, internal multipoint drive.
- Design: Socket head with collared bearing surface; use at the factory-specified driveshaft joint.
- Quantity supplied: one individual bolt; shaft, flange, spacers and other hardware are supplied separately.
The specification describes nominal thread diameter and bolt length. No unverified drive size, torque, strength class, packaged dimensions or weight is provided.
Common reasons to replace
- Damaged internal drive that prevents secure tool engagement.
- Damaged threads, a bent shank or an impaired head bearing surface.
- Missing or incorrect hardware discovered during driveshaft or transmission service.
Driveline vibration can also arise from worn joints, shaft damage, mounting faults or incorrect alignment. Inspect and diagnose the complete assembly; a new bolt alone will not correct an underlying driveline defect.

Installation guidance
Support the driveshaft and preserve any factory alignment marks before disassembly. Follow the repair instructions for flange cleanliness, spacer arrangement, bolt replacement and tightening sequence.
Use the correct multipoint bit fully seated in the drive recess. Follow the specified torque and angle procedure for the exact joint, then complete clearance and driveline checks before use.
Ordering information
New and unused inventory. Sold individually under number N-106-677-01. The cataloged quantity for an assembly does not mean that multiple bolts are included in one order unit.
