Hi all,
Has anyone out there ever changed out this seal on their X5(auto)?? I have looked all over for any tutorials or info about it. There is not really anything good out there which talks about this. I have the part ordered(which has been discontinued and is NOT easy to find!)

My Mechanic is going to change it out for me, but I want to learn what is involved in doing it. I read that you have to be careful not to scratch the housing as you remove it...and that it's a PITA sometimes to get out

Any help or advice would be appreciated
Steve
