I actually sent back my Moser's after talking with Dr. Driff and he had me start taking some tolerance measurements. He said he started making axles because Moser's were always so far off.
Excellent customer service and very knowledgeable.
Stay with mopar, 8.75 big bearing, truetrac & DR. Diff axles.
I would at least call the Doc., he is good at talking people into stuff and he knows both real well.
