F Nut – GM (94169022)

Factory part number 94169022: a f nut supplied by GM. It is catalogued under Nuts & Washers > Nuts.

• A lock nut and a plain nut are not substitutes on a steering or suspension joint, and a wave washer holds preload rather than merely spreading load.
• Match thread size and pitch to the fastener, then match the type to the joint. That order avoids most returns.
• Snap rings and retainers locate a shaft or a bearing without a thread, and one of the wrong thickness changes the end play of the assembly.

Nylon-insert lock nuts lose their prevailing torque after a single removal and should be replaced rather than reused. Sealing washers on transmission pans, drain plugs and A/C lines are single-use, and reusing one is the usual cause of a leak after a repair.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Handed to the carrier within one to two business days from our US warehouse, free over $59.
