After stripping the axle splines out 5 spools over the years, I have converted back to welded and have never had another failure. The spools are some sort of chinese import that USLC is making and I won't trust another. I have probably had close to 10 customers strip them out as well...Too many failures for me.
The best part when you send them back to USLC for "inspection" they tell me everytime, "the rearend housing is bent". Amazing how I still have the same housing in both of my cars with welded gears and no more failures...
Plus, if I had a bent housing I would replace it, I wouldn't be able to put cars in the wnners circle and on the front of the rulebook with bent & broken parts.
