All the problems started with the replacement of ring/pinion of a Dana 35/ 4.56 ratio. Decision was made to remove the D-troit locker and replace it with an open carrier due to the locker not looking too hot; and the fact the vehicle is currently driven on the road more than offroad unfortunately. Once the NEW YUKON spider gear kit was installed, we got about 69 miles out of it and BANG! Once we got it back home, we opened up differential to find a BROKE pin (the spider gear pin). Never seen anything like it. Pin split and twisted right in the middle. Once we got a new pin in place, it now makes a "thump/thud" sound while ONLY turning right??? I GIVE UP!!! Any suggestions of where to start with this nightmare?
