Are the side gears 1 or 2 piece? Doctor diff has a kit to fix that
im not sure i know what you are asking. are the little gears one unit? or two? is that the question?
No, I mean the gears the axles slide into. I also see heavy wear on the spider gears, and thrust spacer, like it was run with too long of axles and green axle bearings with one axle, likely the right side pushing on that thrust block. How about a pic of the axle, axle bearings and the side gears that slide on the axle. If it has greens you may need to.remove that thrust spacer, or at least make sure you have 3/16" between it and the axle on each side.
