Effort/time to replace rear diff bushings?

I'm not able to find a clear answer on this: how much time and effort are needed to replace the rear differential bushings? Does it necessitate draining the diff, dropping the subframe, etc?

The car is a 2011 with only 64k on the clock but with track season finally here I'm considering just replacing it as preventative maintenance with something stiffer.

I was told it was a 10+ hour job by a tech at BMW. Decided against tackling that job or paying labor for it.

I will be doing it this month. Since i have not done it before on this car, i was estimating at least one day. I have done them on E36 before so I understand the process. I will be installing poly, which is easier. Doing diff at same time. Have a press but will likely cut them out instead since I don't want to disassemble the rear suspension just so subframe will fit on the press to press out the old. If I was using stock or aluminum and had to press the new ones in, i might but poly is easy to install in this application.

Guys, to be clear, I'm not replacing the subframe mounts -- only the differential mounts.

I just completed mine. For the diff bushings you'll need to drop the diff, disconnect it from the drive shaft and axels probably (I did this along with subframe bushings) you won't need to drain anything unless you want to. Having a bushing press will speed up the process. Don't need to drop the subframe unless you're doing the bushings for it.

Alex at Performance Eurowerks can get this done in a day without a problem.

Diff alone is easy. Youll be done in a day no problem even for a first timer. Half a day if you have done it before.

Thanks. Doesn't sound like something I really want to tackle, hence the question about hours.

By far...the biggest PIA is going to be pressing the bushings in and out. Dropping the diff shouldn't be too difficult.
