Update: I have a set of Yukon hardcore axles and 5-760x U-joints headed my way, thanks jbg.
I am going to 4 wheel parts this morning to see what the Alloy USA 11500 u-joint looks like. These are greasable at each cap and they are cold forged. If the quality looks good I will give them a shot with the Yukon axles. The price is fair at $40 each.
I have the axle apart now, both of the precision 377 joints sheared right before the cross. I am no expert, but they look like they are cast. The 377 joints have the number 371 cast into the side of the cross. This tells me that the Precision 371 non greasable joints are probably the same as the 377 without a grease passage drilled through the middle. If so then I expect the 371 joints are not much stronger than the 377.
For now, I am swearing off precision U-joints altogether. Early this year I had the rear driveshaft literally come apart at the CV....again precision "super strength" u-joints. I originally took it as being too much torque....now I am not so sure.
My old front axles are beat up, but I think they are salvagable as spares. I will put some 5-760x joints in there and keep them on hand in case of future breakage.
