My frame cracked between the front 2 bolts and the back 2 bolts. The diff is off vertical a bit and the axle on the passenger side is close to the control arm due to the diff being tilted sideways a bit. Any thoughts. The drive shaft universal has touched the frame aswell. Going to add a bit of metal. I have bagged on it a bit. Cross ditches and jumping. Man I love this thing. Its a 2013 with about 700 miles on it. Not complaining just looking for similar problems. I brake I fix.

I just got done repairing the same issue on my 11 s. I just bought it and I was dissapointed to find the frame to be cracked already. I also noticed the front diff to be a little off center. I welded up the cracks then doubled up the differential frame mounts with some sheet metal. Im hoping my repair makes it stronger than stock.

Pounded it straightand welded up all the cracks. Then made a .125 plate that is 2 x 5. You need to notch it for the drain plug. Bolted it together then welded the plate in place. Also made some .125 x 1 x 3 shims to raise diff a bit. This gives a bit more clearance on the CV boot to frame. I have one friend who hit a cross ditch hard and it tweaked the diff enough for the clamp on the boot to rub.
