Default Rebuilding the LSD

My LSD has finally passed on and I hope to send it out to Guard for a rebuild.
I say hope since I cannot figure out how to get the LSD passed the drive shaft.
Is there a trick to this that I can't figure out?
If you have solved this puzzle, I would appreciate your help.

TIA

Maybe remove the axle entirely, or drop it lower?

Push the hoses up, push the axle back and down/up, then wriggle the LSD out with your other hands. It's a bitch, but can be done, forcibly but with care not to rough up the casing. Getting it back in is even a bit harder.

Removing the axle ahead of time makes the job a lot easier. Or...taking the whole engine/trans out! I just rebuilt mine with Guard parts as I type.

+1. Take extra 15 min to remove the axle and make the LSD in/out a lot easier.

Thanks guys. Maybe removing the rear axle is the way to go.

Oh, I found a great test for the proper function of the LSD. There is a tight turn #3 at NHIS. If you take it in 2nd gear going up the hill after the turn, the driven wheel loses traction. It will feel like you lifted the throttle midway through the turn as you spin of the track. I took the turn in third for the rest of the weekend, feathering the throttle. Still I had to catch her on nearly every run.

Success!! A buddy came over and I held the drive shaft up while he wrestled it out. We also loosened the stiffener for just a little more room.

I am going to leave the ring gear on and ship it to Guard.

Dave, so is it a fairly reasonable job for a DIYer? I mean, I have seen the LSD Buster thread, but just want to hear another opinion..

Reasonable? Yes. I give it a seven out of ten in difficulty. I am no mechanic by anyone's definition but I managed it. I also have a scissor lift in my garage that helps.

Mikymu's DIY is very good. Only subtle differences with our car. The axle flange bolts are hex head rather than torx.

Nice.. yeah, no lift here.. if I am doing it, I'd have to use jack stands or some wood block under wheels...
