First I bought wayyy too beefy z3m axles which were much too big on the hub side. Then I ordered e30 half shafts which, and I'm not losing my mind here, are LONGER than my stock ti halfshafts. Also have bigger axle nuts which were not included. Since I had the original diff and stock halfshafts, which were the shortest ones I had, I installed these parts. The ti output flanges are machined to 'snap' in at a different location than the e30s and slightly out from the diff. For this next step, I went ahead and bumped them all the way in. SO, when I put in the ti axles guess what happened?,. My ass end got a lift since the axles won't even let the rear drop all the way. My question is, where did I go wrong? Only makes since to me that somehow my 'e30' half shafts are longer than normal and I should ignore insanity and order another pair... __________________ Ian | | | 08-28-2013, 03:44 AM | #2 | Senior Member Join Date: Jul 2007 Location: norcal - 94590 Posts: 3,186 | Quote: Originally Posted by 318tian I have swapped up to a 3.15 torsen med case diff.

I used e30 m3 halfshafts, fit perfect, only had to shim the ABS sensors. The correct e30 shafts are shorter (because the case is larger and wider) and must be from a 6 cyl e30 (or e30 m3) that came with the med. case diff. No output flange issues either. Maybe you got 4 cyl e30 halfshafts by mistake? __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.

I've been running an E28 3:25 lsd med. case with the E30 parts with no issues. | | | 08-28-2013, 09:09 PM | #4 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | Yup, E30 med diff, output flanges, and axles here with no issues. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 08-28-2013, 11:00 PM | #5 | Senior Member Join Date: Aug 2007 Location: louisiana Posts: 188 | I checked the parts numbers and e30s all came with the same shorter half shafts. Supposedly. And mine are from a 325 anyway. But just so you guys understand I'm not losing my mind I will post pics soon of the longer e30 half shafts. __________________ Ian | | | 08-28-2013, 11:06 PM | #6 | Senior Member Join Date: Aug 2007 Location: louisiana Posts: 188 | Sitting freely on the ground and standing pushed down on end they are LONGER?! And notice the ti output flanges are designed to pop into place while still 1/4inch out of the diff. Now, it's not just me. Hah. I can't talk myself into ordering more e30 half shafts and expecting them to be shorter. Especially when I could use that $100 or so to regrease and re-boot mine.. __________________ Ian | | | 07-13-2014, 09:46 PM | #7 | Senior Member Join Date: Aug 2007 Location: louisiana Posts: 188 | Just to clear this thread up, I ended up buying brand new e30 half shafts from the parts store for a very reasonable price after figuring out that the "e30" half shafts I received from a bf.c member were for an e36 with bigger wheel bearings/hubs in the rear. __________________ Ian | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
