Q: I torqued the axle nut on my 1996 BMW 328i to the spec of an M3 and want to know if I may have damaged the axle in some way.

To whomever this may concern,

I have been working on overhauling the rear right side of my car (axle, bearing, rotor, caliper, brake shoes, etc.) for the past few weeks. Last night I was finishing up when I over-torqued the axle nut to the spec of an M3 instead of the spec of a 328i (221 ft/lbs vs 184 ft/lbs). Only when I double checked the torque specs this morning did I realize my mistake. The car was driven 50 ft up the parking lot to another space very very slowly (slowly because my breaks weren't bled and I was using the parking break to stop).

If fixing this is as easy as replacing the axle nut with a new, properly torqued one I wouldn't mind. My biggest worry is that the new axle threads or parts of the hub/bearing get damaged. If damage is probable, would I be able to tell if I remove the axle nut and look at the axle threads? Or am I over-worrying about something with an easy fix? Thanks in advance for your help on diagnosing the degree of my mistake.

Best, Marvin
