looking for used diff in uk

[Uk Merc Man]

hi there i am after a used 190e 2.5 16v rear diff as mine is whining badly. i have called some of the local breakers but no luck as they dont get these types of cars in very often.

or what about a rebuild kit? i have heard these are available from MB-whats involved in fitting them? whats included? when the diff starts to whine what actually needs changing?

anyone got any suggestions?

many thanks,

steve.
