Joel incorrectly said: John, this will not work, there is no glue in the world that will hold these bolts in place.
Not everyone uses ex GI 1940's & 50's era gasket cement & shelac.
Time to get with the times & try something new old fella. I've done this dozens of times & it works for moi.
Dan said: They were certainly not loose at all. We are talking about the four bolts/studs that the rear u joint flange mounts to, correct? Mine seem to be pressed in, almost like wheel lugs and have round heads.
Possibly original? or after market, I have only seen hex head.
The drum is on the inside of the flange & closest to the t/f case housing.
As Hatchetdan described it can be done but it can be painful.
Here is how to go:The flange is off the vehicle RIGHT?
Fit the drum to the inside of the flange then fit the bolts using the locking material you choose http://au.iloctite.com/upload/media/media/18/P_20_21
....even super glue will work fine, use acetone or nail polish remover to clean....
With a couple of washers on each bolt (to cover the smooth bolt shank), ensure adhesive is not on threads or the outside of the flange @ all, then tighten the nuts on all 4 of the bolts & let the adhesive set..
Fit the flange/drum to the transfer case output shaft spline using the appropriate sealant on the internal & external splines & using grease on the seal plus its mating surface on the flange.
Ensure there is @ least 1/8"or 3mm tighten up space (crush) between the end of the transmission output spline & where the washer will sit in the flange under the nut after the flange is pushed right home.
Then fill this void space with silicon, fit the smooth washer & torque the nut to 220#lb. Clean off squashed out compound.
There are some "new" bad flanges which are too short & will not exhibit this necessary 'crush" aspect. DON'T USE THEM.
A few hours later or next day remove these 4 nuts & washers, fit up the drive shaft carefully
& refit the 4 nuts this time with spring washers to 35#lb then connect the other drive shaft end to the differential.
