Front Differential R & R

[djhallenb]

Have a Trailblazer LS 2005 with Gu6 3.42 Front Differential which I am changing out.
So then what is easiest way or hardest? 1. Drop Oil pan & Rack, 2. Jack engine after removing mounts and jack to the passenger side
or 3. drain water, remove bat & tray, alternator hoses, thermostat & pull aside A/C compressor and pull diff up to the top?
Have read all three ways just curious of which do you advise. Thanks

Hope you get some input from the experts here, I think I am going to be doing an R & R soon myself (leaking seal between diff and oil pan on drivers side).

I was thinking of going with your option 3, mainly because of this writeup:

Wish the pics still showed up in that thread.

I believe this thread has a decent write-up for the swap. http://forums.offroadtb.com/viewtopic.php?f=11&t=4620

Thanks for that link djthumper, lots of good info there.

I like that method better than anything I've seen or heard about so far...I definitely don't want to pull the oil pan.

Just don't install the outer seal in backwards like the one in the pic

This was the other article that I was trying remember. Dirtybacon's write was excellent though.

Yeh, I think I like that method even better...bringing it out the bottom and no pulling the oil pan.

Guess I would replace the 3 seals (diff @ oil pan, diff @ drivers CV and pinion seal). Is there any other seals or anything else I should do while I have the diff out?

From past experience...the best way is to get someone else to do it.

Yeh, I hear that.

Kinda looking forward to it now though. C'mon warm weather!
