BMW X5 2002 E53 Transfer Case Full Rebuild (NV125) Part 2 of 2 

Good job and again showing the mistakes too :) I should try to get my inspiration with the E53 back too and do it little forward with some rust jobs

Had no idea NV had products make it beyond the US auto makers. Nothing special about the fluid. ATF+4 would be more than adequate and you can find it everywhere.
