Mostly done.. thought I'd share some pics for anyone who might be curious. There's a good how-to on the LSD install from h-kuevo on the other site (many, many, many thanks for that).. I had a friend help me so that I could try to catch pictures of all the inside of the transmission work that there were fewer pics of.. Step 1: remove just about everything that isn't the engine or transmission from the car :wink5: easy, right? (for more details, go look up that how-to) Step 2: remove transmission: old throw out bearing (pretty shot).. was glad I had a new one on hand as recommended Step 3: open transmission: line up all bolts neatly in a row (ok, kidding, that's just my OCD kicking in) tada.. old diff: new vs old: new diff: cusco 1.5 way clutch pack LSD Step 4: just add (swap) ring gear.. Removal from the open diff was not too bad with air tools. We managed to torque the bolts back up on the LSD by having one person hold on to the ring gear with heavy (very heavy.. it's quite sharp) gloves while another handled the torque wrench. Criss-cross pattern, naturally.. and mark the bolts.. it would be bad to forget one. insert in to transmission: spread on some strawberry jelly (anaerobic sealant) ... and close: By this time it was getting dark, so we closed it all up, tightened up the bolts (30ft-lbs) and let it set over night. Today it'll be getting the trans back in and all that fun "installation is reverse of removal" stuff.
