My diff; late 95 318ti, had to put a thumb size dent in the crossmember, nothing more, for clearance. Medium case from an 88 325. Gutted it, started over. 4.27 ring and pinion from an auto trans 525i. I refused to pay 1400 for a set of "motorsport" gears when these are a dime a dozen in the euro junkyards. Bought the whole diff for 150. Helical M-Z3 center. Ebay. 500 bucks, Nearly new. M-Z3 Cover New (not reman) e30 6 cylinder C>V shafts. Rebuilt with all new bearing, ditched the speed sensor as the shop mixed up the tone rings and didn't know which one went in. After trying 3 different sensors I said screw it. |
