What parts for a full rear end rebuild?
 

I have a 2.93 E30 LSD with 3.73 ring and pinion gears to swap in. Right now the stock Ti diff is in the car. What parts do I need to rebuild the inside of the E30 diff and put in the new gearset, and what do I need to completely refresh the rear end of the car? Do you suggest rebuilding the E30 axles as well? If there is already information on this I apologize!

You will need at minimum: - e30 axkes for the medium case diff (they are the correct length for medium case diff) - differential output flanges that match the above axles - shims for the ABS sensors - CV joint nut locks Diff Parts: - Crush sleeve - seals and gaslets as needed (suggest replacing everything if you have it apart) - red loctite for the ring-gear bolts Recommend taking a methodical organized approach for the diff rebuil and have a clean place to work. Measure and verify everything (gear set - depth of engagement, back lash.etc...). Install a new crush sleeve and torque the input flange nut per the specs to get the correct running torque value of the pinion gear. There is lots of information on the web that applies to the differential you are working on. There are many good DIY's out there for this rebuild with pics and PN's for the seals and gaskets. Rear End: Wheel bearings, T/A bushings since you have it all apart, I think everything else can easily be done without removal of the trailing arms. Good Luck!
