Thread: axel nuts keep coming loose?

Yea... I don't know what kind of hub bearings you are using but an impact gun shouldnt break a bearing. At least the hundreds ive done have never broken.

it says on the box not to use an impact gun ..apparently you can damage the bearings from the hammering...i doubt the bearing would get damaged, but the problem is the bearings need a certain pre-load (118 ft/lb factory spec)...an air gun would just over-tighten them and the bearings would heat up and wear out a lot sooner.

Get a air gun, tighten it, done.

I did use an air gun, about 2 years ago on my old car...bearing made noise after a road trip from Ontario to Colorado...failed soon after. Mechanic laughed at me when i told him I tightened it with an impact wrench I learned my lesson
