As of today my driveshaft's are still in the shop. My shaft builder Todd told me that he is still waiting to get to mine but the u joints are still in like new condition physically, however the seals are hard and dry around the cups. They will be replaced anyway. He looked at my truck and the angles and told me that they really aren't that bad as the truck only see's 60mph. The u joint that are in these trucks are rated up to 40,000 lb. loads. Plenty for these trucks. I think he said they were 6010 joint size??? I forgot what he said the size was. He said that the thing he is surprised to see is, my truck has 20,000 miles on it but they are worn like it is actually 120,000 miles. His comment was that I may have been greasing them but the prior users didn't do a good job at it. That's probably where the wear came from. And again, His quote, " hinging, lateral spline movement, call it what you want, there should be ZERO. If there is better get it fixed. That tolerance is for moving the truck around, not driving down the freeway. If you want to go with those tolerances, good luck to you" end quote. Once I get my shafts back I will give full report.
