Sealing Diff Cup

[JKLNHYDE]

Is there any reason I shouldn't use a thin bead of gasket maker to seal up my diffs especially if I fill the diff, put the bead around the top of the cup, carefully place the gear on and screw it down tight, leaving it in that upright position for a day to cure? I'm not talking a huge bead that would ooze into the cup and eventually become floating around. Just enough to seal it. Cups are aluminum Novas...Thanks for the input...

it may throw the diff out of balance, but if you use a thin enough bead, you might be ok.... what about finding an o-ring instead?

An O ring would be a great idea if they machined a groove for it but it doesn't exist. The worst case scenario is the diff ends up leaking...I may try it.
