E28 Diff install DIY

[cracker red]

IF you wanted to upgrade the axles, is there a bolt-in solution?

I've already got a e28 LSD sitting around that should be the perfect ratio (3.23) for what I will end up with (m50 turbo).

E30 axles can be bolted in using their flanges and shimming the abs sensor.

Thank you. There is a lot of conflicting info out there (which is why I asked).

For the time being I'll leave the ti axles in and see what happens. It's not as if I'm going to put huge wrinkle walls on the back end and launch the car all the time.

Hoping for ~350whp w/m50 swap and some boost in the future.

hey Tony I just bought the same LSD as you during the time of this swap, I'm looking to get some E30 axles and a the finned cover before I throw it in.

Anyone found the fin cover anywhere for < than $270?

there are a bunch of them in the local u pull it...attached to medium case diff's on e30's.

I'm going to try and get there sunday, I'll snag a second one if I can, but no promises.

Contact Randy Forbes on bimmerforums.com, he may have a few sitting around.

Thank, he had one for me.

I found a medium case diff from a E28 and I am trying to get the output flanges installed correctly. The one side popped right in with no gap and the other pops most of the way in and leaves about a 1/4 gap. I wondered if it mattered and tried putting the diff in the car with no luck. I remember reading that someone had a problem like this and ended up taking one of the grease covers off one of the half shafts to make up the difference. This seems like a hack that others have not had to do. Any suggestions?

Ok I got it in. I just had to pull out the output shaft and rotate it slightly and try again. With a little finesse with a hammer I got it to go the rest of the way in and everything fit correctly when I put it in the car. Now tonight I will get the exhaust hung back up and will be back on the road.

so you put E30 flanges on the E28 case?

[Xenocide]

I am not sure what he did, there is no difference between the case on an e28 and an e30, only the rear cover. This should not effect the output flanges.
