Just jack up the back end (please support it with jackstands!) and clean the
road gunk off of the differential.  It should have a number (such as 2.93 or
3.73, or 3.45, or whatever) and a letter.  If the letter is an 'S' it is a
limited-slip differential.  Don't assume it is a 2.93 ratio, as I discovered
that the PO (thank you!) had installed a 3.73 LSD on my '86 325es.
