I use my truck to get up to my cabin, steep dirt road. Particularly when I go downhill or make a tight turn with the hub locked there is a loud and noticeable clunk ever so often, like something in the front hubs is skipping. Anyone run across this? It seems to be OK going uphill, which is really when I need the 4wd. I can take it out when descending or turning on flat ground if necessary but it's nice to use the engine when descending.

Possibly a CV axle going out, maybe a bad hub.
Put the truck on jackstands and put it into 4wd. Block one front wheel and turn the other backwards and forwards and see if you can duplicate the noise or pinpoint the slack in the system

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.
You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

Got out to my ranch yesterday and crawled under the truck. Sure enough, one inner boot missing, two others cracked (I just got this truck). Could a bad joint actually skip?

It can't work part of the time. Either it transmits power or it doesn't. In either case it may or may not make clunks.

Thanks guys. It's a 1980, and when it clunks I think it does momentarily skip. I'll check that out. One of the old boots looks like it's a split boot that you put on without removing the axle. I'll check into the 240 kit.
