mickeyw Posted April 16, 2009 Share Posted April 16, 2009 Is it possible to take a crownwheel and pinion from a 2-pin diff and fit it to a 4-pin unit? When I first got my 90 it had a 4-pin diff (V8s got the H/D rear axle). One day the nose of the pinion snapped off and there was a bit of a crunch. This happened at quite slow speed when I had to bump start the truck. As a quick/cheap repair I slung a spare 2-pin diff in and the 4-pin took its place in the garage with a view to fix it one day. After some years I'm now on the second 2-pin diff and my thoughts return to the 4-pin unit. Do I need to buy R&P that's specific to the 4-pin or are they swappable with 2-pin types? Obviously I'd make sure the crownwheel carrier still runs true before I tried any rebuilding. 3.54:1 BTW TIA Quote Link to comment Share on other sites More sharing options...
