Shop Cost of Installing LSD
Bought an LSD last month during the 928 Intl sale. Finally decided to call for a quote to install it in my 87' automatic. They quoted me $1400 including an alignment. Is this reasonable?

Doesn't Carl sell the LSD's for around $325 (old style) edit..oops...looks like it's $600....and his metal spacers too make them fit the S4's ? I think it was like $200 for those?

If they are doing it by the book, remember they have to pull the transmission out. IIRC that involves dropping the crossmember, alignment, all that fun stuff. 12 hours' work and a couple hundred in incidentals(fluid, filter, etc) may not be that far off.
I believe that Carl's kit allows you to retrofit the transaxle to LSD in-situ, saving you all that trouble and skipping many of the shimming steps that the shop may have quoted. He posted a thread on it here.
Might want to give Carl a bell and talk to the shop -- $227 plush shipping might save you several hundred in the end.

We do this all the time.
You can actually remove the old differential, without removing the transmission. The old differential can be measured and compared to the new differential, before the ring gear is bolted on. Not all shops will have the ability to measure these two differentials. Almost need a shop that also has a machine shop, with measuring tools. You can generally change shims, from side to side, as needed. Sometimes you need different shims, if there isn't the correct ones needed to swap around. Takes about 6 hours.
Make sure to have the used limited slip rebuild/gone through. Those single discs wear out pretty easy...especially if someone ever used a gear oil without a limited ship additive. Sometimes the inner pressure rings get destoyed, too.

There must be a good trick...Tried it with Adam's car and it got wedged inbetween the tank and diff pretty good. Ended up dropping the tranny to get it out...

I don't see how you could do it in-situ with an automatic which sits farther back in the body than the manual.

I think something could be in the way for sure, but i just am not sure its the tank, i think its the metal from the body and the battery tray.
I COULD BE WRONG, i am not looking up the *** end of the S4 though.
