Must have missed my other topic a couple weeks ago, explained some things.
-Driver rear hub was seized to the halfshaft. Figure I can have the shop press it out, no biggie. Attempted to remove shaft...stuck in the diff. Opened up the diff (dumping all my year old Royal Purple), and found the damn clip on the end was the cause. Despite the fact, that it shouldn't have created any issue. Had to dismantle half off the gear assembly to get a pick in there. Many, many hours with a dental pick, finally got it off.
-Ran it down to the shop, and 10ton press couldn't budge the halfshaft out of the knuckle. So I had to order a new halfshaft, and source another knuckle.
-Get everything ready to bolt in. Stab new halfshaft in, then realize I need to remove it again to set the spider gears. Guess what, both are now stuck in the diff. Same cause, the clip on the end. So again, couple hours later, neither shaft has a clip now...and never will again.
-Destroyed many Dremel grinding bits, while clearancing everything. Get one rear completed. Fight the other side for about an hour. Then realize my relocation bracket is tweaked just enough to cause an alignment issue. Luckily the guy who makes them shipped a new one,via 3 day express.
Front didn't present too many issues. Had to modify the brakeline end to work. Did a short test drive (down the block and back). Seems I have to bleed the system again. Not a major issue, just an annoyance. Took me an hour the first time with a one person vacuum bleeder.
I know I am forgetting some of the other hangups, but those were the main causes.
