[antony_e]

hi guys i think this is my first post but anyway hi bit of a dilemma however im trying to remove my nearside lower wishbone after a slight ice incident but my main issue is i cant undo just one bolt. ive circled the end of the arm below that im having trouble undoing,the only part that i can get on has rounded and now im stumped as to how to get it out?

any suggestions greatly appreciated
thanks - ant

on my ex M3 i had to remove the differential... in the 318is which has got a smaller diff i don't know if you can do it anyway, so i suggest you to loose the diff bolts without removing it, push it as far as you can from the wishbone (it moves just 1 inch) and then try to loose the bolt #14; the piece #15 cannot rotate cause it is blocked in a little hole of the diff cage.
anyway that bolt requies a lot of time to be removed
