    Leaking dif and rust

    Hey guys,

    I'm looking to buy a 89 325i coupe and noticed what I think is a slightly leaking rear dif and some moderate rust in the trunk over the rear driver side wheel well. Should I be very concerned about these two issues and what is ballpark range for repairs if I go to a 3rd party shop?

    Thanks in advance.

        Couldn't really tell, car was too low. But I saw a droplet on the bottom of the dif and a couple of drops of fluid on the ground after the car sat for about 25 min.

          a little visible rust means a lot of hidden rust

            Usually the case. I had no visible rust on mine but when I pulled the carpet and the interior in the trunk i found a good amount of rust. A few drops every 25 min is a decent leak.

              A couple bolts on the diff can be hard to loosen, but after that its not bad at all. Seals are cheap and I believe all of them are easy to fix.

                how difficult/time intensive is it to pull the carpet and trunk lining?

                (I'm considering doing this before investing a decent amount of $ into my car)

                  Trunk lining is extremely easy, I've never done the carpet though.

                    Carpet can be a bit of a bitch, especially when putting it back in

                      Run from it. From someone who purchased a car with "little rust" and found huge holes in his floorboards, run run run.

                      It's much easier to find a clean example (even if it takes you a couple more weeks) than it is to cut and weld.
