I have a problem - any suggestions

[hmcoleap]

Heya Scott,

He said there was a bang, and then he couldn't drive anymore... if it was a carrier bearing, I would expect that to generate a lot of noise-- but a seized carrier bearing wouldn't halt his prop shaft to the point that he can't move the vehicle in "H" on the t-case unless he also broke something else, too!

they can be purchased at a local autoparts store but need to be pressed on and premoved... just ask for one from a similar year / engine Chevy Pick Up.

well... when this happened to me in my Humvee it made a ton of racket once I slowed down at constant speed it was fine because the torque was already applied... BUT when I slowed, the driveshaft fell and started to bind up... if when the bearing fails and the bracket was to bend / fail as well it could easily bind up the driveshaft such that the vehicle wouldn't want to move...

its been a while.... whats the outcome of this??

Sorry - no outcome yet - I was so busy this last week that I just did not get around to taking it in - I have been driving my old CJ7 all week.

Monday I will drag it in and get back to you - thanks to all for all the suggestions at least I will go in sounding as if I know what I am talking about.

OK I have finally gotten around to looking at the problem myself - Duh - blindingly obvious problem - but one that I have no explanation for.
The right hand side halfshaft has dropped off of the diff plate - I mean the whole thing - all six bolts gone - no signs of shearing - all the holes are still threaded - all I have to do is bolt it back on - I think.

The laft shaft is still in place with no bolts backing out - wait the bolts couldnt back out - the brake caliper would hit them if they tried to come out - even stranger.

Anyway - I will bolt it back on and see what that does.

OK - bolted back on - working perfectly - weird that all the bolts would back out causing no damage to threads and showing no signs of wear around the plate holes - a mystery to me.

No Andy thats no mystery. The halfshaft bolts are notorious for backing out. Its a good idea to check them at every oil change if possible. I would advise using red threadlocker on the bolts. You may as well just replace them all along with the nordlock washers. Do yourself a favor and get it all from your local stealership, you want to make sure that the bolts you have in there are the proper grade, as far as the nordlocks go you have to get those at the dealership.
