923 hub bolts backing out

[Draco-87]

Changed out the hub seals on the 923 got new lock washers and torqued the bolts to TM specs. drove for about 40 miles and all the bolts were loose, re-torqued them again and drove for 20 miles and they were loose again! any idea's?

Bad bearing

Bad bearing

He is correct, I had the same problem on my M931A1, it was a bad bearing..

Well crap! looks like all new bearings for both rear axle's!

 

[doghead]

Your using a dry gasket, correct?

 

[73m819]

look for a bit of dirt or metal on a roller or in the race

I would pull it apart and do a good inspection of bearings and races. It could be that a spindle nut backed out too.

Yup, dry gasket. Going to have a friend of mine check this out he's master at this sort of thing.

Update: my buddy checked out and replaced the hub seals on the old girl. good news is the hub bearings were in top shape! after looking at prices on the bearings I'm relieved there still good!

What did he find, that was causing the bolts to loosen?
