Hi All,

I have recently brought and front diff for my 2005 Range Rover, on the sticker on the diff says 3.54 ratio - 09/09/09 and on my current diff has no sticker.
my mechanic done a few checks and said this the wrong one because the numbers on the side did not match the ones that is on my car at the moment.

I have checked with the breakers yard i brought the diff from and they have confirmed 110% that it is the correct one?

can someone please advise me who is correct?

Does the numbers on the outer casing have to match on the diffs? as my mechanic thinks the numbers have to match.
the one on my car is 3652 DT-2 and the one I brought 3652 C0R-2 he also think these have to match would you know anything about this?
