4 bolt Rear Diff Rebuildable?

[blackmirage]

I just got my 4 bolt rear and I'm getting the axles taken care of and beefed up.. but I was curious if before bolting it all up if I should/could have it rebuilt.. I read on a post here during a search for this topic that one should just buy another rear diff if it goes out.. is that to mean that its not worth rebuilding??? I just didnt want to bolt it up to find out several runs down the track later that I should have had it rebuilt while I had it out to begin with.. rather measure twice cut once kinda thing.. any help is greatly appreciated. Thanks.

The LSD is a sealed unit, so you can not rebuild that.

ok so run it till it blows and get a new diff when it does.... anybody sell beefed up
center diffs so when it does go i can just get something thats brand new rather than another one that may only have 200-2000 miles or WHATEVER on it... ya know what I mean?
