This is Murphy from Taiwan, nice to meet everone here!! And pls forgive my poor English to present the question......
I have a very old E34 525i(MY1990, 5MT, Europe Version), and recently I can hear a strange noise from the underside of my car. And the machenics told me that is the sound of the differential, he said this diff is too old(around 190000km), and there is no safety issue but if I want to end up this noise I have to change a differential.
I find a used 1993 differential from 525i, the ratio is 3.23, but I do not know the diff ratio of my car and this 1993 used diff ratio can fit my car without any problem? Some one told me that the diff ratio of my 1990/E34 525i is 3.73, is that true? Can I use that 3.23 diff?
The most thing I worried is other guy told me:{since the engines are different, the diff's are probably different too. changing to a lower ratio one would just slow the acceleration down a bit.} :( :( :(
So that means my E34 will become slow in start? :( Or mid-rev range? Or hi-rev range?
