Well, my open differential in my 96 has started to make a hissing noise at speeds over 25mph. I jacked it up and went under to find out what's making it, and I think its the front bearing in the diff, but it may be more inside the diff.

Question #1: Whats the expected lifespan on BMW diffs in a 318ti?

Question #2: Since I think I need to replace it, now is the time to "UPGRADE" to an LSD. What fits, and where are good places to get used or new ones from? I somewhat regret to say I have an automatic (although its nice to be lazy sometimes), so I think I need a 4.44 ratio.

I searched around and see different posts about 4cyl Z3 diffs fit, and maybe E30's, and other E36's, but some of the post get sidetracked or get detailed into having to work in new shafts that dont fit. I want something to bolt right up with out a bunch of re-engineering to mate something else in there.

Thanks in advance for the help!
