But you should fix it the "right way" if you plan on keeping it.
I can remember an old friend stuffing two loaves of bread into a Chevy 10 bolt, back in the 1980's!
To the O/P, have you been able to verify that it is actually the rear axle making the noise?
I'm thinking it could be the T-case. If you have a rear driveshaft slipyolk, there is a bushing in the tail housing. It's there to keep the slipyolk from wobbling.
If the seal back there is leaking, it's a good idea to replace both the seal & the bushing.
