eLSD swap out help

BMWX1-35i · 11-21-2014, 09:07 AM

I'm thinking about getting an MFactory LSD. But, I'm not sure what's needed. I have seen that the 1's have a welded ring gear but I'm not sure and I don't want to move on this in any way unless I have all the details.

My car is a 2009 135i auto with a mfg date of june of 2009...

All 135i autos are bolted style diffs. Will you be buying a whole unit(pumpkin) or just the LSD? If you purchase the pumpkin all you need is to buy fluids.

I was just going to get the LSD and have it swapped out. I did not know the Auto's were bolted in, thats good news.

Yup, all AT's are bolted, so is just a matter of opening up the core, swapping out the oem diff for the new LSD, check/shim the backlash, then bolt everything back together

Can that be done without dropping the subframe?

That's a good question. ^^^^

Subframe doesn't need to be touched; just simply unbolt the differential unit.
