They were a REAL BITCH to break loose, made me wish I had my 1/2" drive set with me.

Example of ****** Taiwanese socket that somehow found it's way onto the holy socket holder. :flipthebird:

Had to break down and use the deep socket 6 point jawn after this broke, the 12 points weren't cutting it, just rounding it..... :flipthebird:

Orange gasket goop in the bolt holes means somebody already had cracked this egg before me. :jawdrop:

The cover was easier to pop open to drain with the RTV sealant than the gasket job on the front.... :High 5:

Cleaned up the diff housing mating surface and cover surface.

Also found a factory installed magnet on the cover that I took off and cleaned and reinstalled. :High 5:

Installed and torqued down, same as the front cover, criss cross pattern, little more tourque at a time, light to heavy.....

*Note the 2 brake line brackes that mount on the ouside of the cover.

Time to fill'r up!

Unlike the front rear, the rear rear fill hole is not in the cover, but in a nook on the front of the axle housing on the passenger side facing towards tho wheel. You will need a 3/8" drive extension or ratchet to fit the hole perfectly and remove the plug......

I am 6' 2", 325 LB, and I could not break this fill plug. I had to make a redneck breaker bar for the ratchet handle, loose the extension, and put thE ratchet itself right in the plug. I got to give some credit to that little Craftsman 3/8" drive ratchet for the abuse, it did DAMN GOOD. :High 5:

Once I got it broken loose, I used the extension to thread it out.....

You sure that's a factory limited slip??? What is your RPO code for that??? That is certainly not a G80 Eaton Gov-Lok, aka Gov Bomb cuz they are junk. That's a better set up there for sure. Maybe even an Auburn unit. Could also be an Eaton system, but its not Gov-Lok. I am thinking that was added after factory and is not OEM.

did you get the numbers on the ring gear to tell you the ratio?

good LS diff too not a gov lock from the looks of it.

I HATE the fill plugs, they always get stuck and rounded off, dad's 84 had a bolt head plug in it now thanks to it being rounded off.

Yep I seen the #'s 41-11 is 3.73. Easy to figure out. 41 / 11 = 3.727272 is 3.73.
