thorburn 121 Report post Posted October 12, 2012 rebuild or buy a new diff small case or medium case. If you've got the gear and time to rebuild it I can go into it in more detail Quote Share this post Link to post Share on other sites

If you've got the gear and time to rebuild it I can go into it in more detail I have no idea what the difference is. Is there anything appearance wise that would make me tell the difference?

_ethrty-Andy_ 2132 Report post Posted October 12, 2012 between small and medium case? they both are cross compatible (just have to use the built in adjustment color on the driveshaft itself to shorten it. But the small case has four mountaing bolts on top as will as the hanger, the medium has six or 8 to do (been a few years since ive done a swap) Quote Share this post Link to post Share on other sites
