After getting the rear diff in my 2007 Puma replaced last week, a HUGE amount of clunking/slop has disappeared. The difference is startling and most noticable.
At standstill, just depressing the clutch in and out swiftly used to make internal clunking noises. Now they are gone.
1st to 2nd, and 2nd to 3rd used to clunk very noticably. Now there is no clunking between the gears.
Not sure how a new diff can make such a difference, but there you are. I've only done 300-400Kms since it was fitted, so am hoping the noises don't come back after a few thousand KMs or whatever.
