The u-joint I removed did not have the locking clips. It did have split-ring lock washers, though. The new u-joint came with something I thought was rather strange. The caps actually had like a loop of metal on either end that the bolt went through, which left a little gap. When you tightened the bolt, the gap was reduced. I'm assuming that is some type of springy material that puts pressure on the screw head. I reused the lock washers anyway, so it has two locking methods. Also, I was a little surprised that there is no torque value on those capscrews in the service manual. I just got them good and snug.
Concerning the second front bushing...I was thinking about that. I have to assume that the guy who did it didn't have a bushing puller. And, really, back in the day, that may have been an accepted repair. As I understand it, okie bushings didn't come along til the sixties. These trucks had already been on the road for twenty years. Unless you are installing an okie, then you could stack four or five of those bushings back in there before you hit the rear bushing/seal. Just a thought.
Thanks again for all your help. Now I have to find something else to fix.
