    I noticed an oil leak from the axle flange on Saturday. To my surprise, all of the axle flange bolts had completely backed off. Anyone else had issues with axle flange bolts coming loose post installation of a locking diff?

    It's all sealed up again and torqued to 115lbs so I'll monitor them closely now. Just curious if this was an anomalie.:confused:

    do the bolts have lock washers on them? did you torque them correctly the first time? I havent heard any problems with bolts backing out with a locker, Ive had my locker in there for 6-7 months and do alot of street driving and I havent had any issues with it yet. If it does it again, which it shouldnt, use a little loctite on the bolts too.

    Did they come OEM with lockwashers? mine do not have any lock washers. Should I run by fastenal and grab a sac of lock washers while I have my axle shafts out anyway?

    There is some sort of brittle seal that goes between the hub and axle shaft flange. What is the part number for that so I can put a new one on when I put the shafts back on. (or would I just be better off using some RVT?

    this little guy right here.. is there a part number for it, or do you reuse it, or can you just use a glob of RVT instead??

    James, there is a part number for it but I don't know if off the top of my head. You might want to check in the parts number post. I know mine are NOT brittle, mine are made of sheet metal.

    Mine sealed fine after locker install and havent loosened. Try a little Loctite on the threads.

    No problems with mine.If torqued to specs,it seems like sufficient torque for them to never back out.

    mine would loosen up with a detroit and a heavy foot. longer bolts, lock washers and locktight did the trick

    That has happen to me like 3 times now... I thought it had to be the fact that I'm running a spool... but it hasn't do it for awhile now... just keep checking it and make sure u use some locktight....

    Loctite and lockwashers. Atleast mine had lockwashers when I took them off. I also only use RTV on the flanges I do not have gaskets. Make sure it is clean and let it skim up before bolting it down good and tight.

    I've had the Detroit in my 14BFF for over a year now and I have never had those bolts loosen up. I have checked them a few times before wheeling and they have been tight.

    When I rebuilt my axle, I reused those stock flange gaskets with out any leaks so far. I just cleaned them and slapped 'em on.:D
