    I just repalced both U-Joints on my rear drive shaft. The U-Joints fit perfectly. Now the problem I have is that the rear u-joint doesn't fit in the pinion. It's to big. Is it possible that there are 2 different sized caps for the rear?? If so, is that a special joint? Any advice would help. I need my truck.

    Well, unless you've got a different rear axle swapped in or a different driveshaft, the cap sizes should be the same on both. If you've got a 12 bolt it should be a 1330 joint. If you've got a 10 bolt, it should be a 1310. Yes, there are conversion joints out there. What rear axle do you have?

    It's the factory 10-bolt. The drive shaft is 2 years old. It had the nylon locks in the joints.
