Alright, a couple days ago I finally got my yokes fixed. Now guess what... I drive it too a friends who is a body man to look it over, and I'm getting rady to leave, and fire her up, and I hear it knocking. Now, I suppose it coulld be the torque converter..but it only knocks when warmed up, and it's definately bottom end. Since it only does it when warmed up, is it prolly one of my main bearings?

Sorry, misspoke myself, meant to say rod bearings. Is it possible to check with the motor still in the truck, and what do I look for?

While the engine is at idle - and the knock is clearly audible, with an insulated tool pull off each spark plug boot individually, if you hear a difference or the knock goes away altogether - that's the likely culprit.

Don't mean to argue with you OP, but what difference does it make which rod is knocking. Running the engine to do your check will only cause further damage. In my opinion, you should pull the pan (It can be done with the motor in the truck) and the damaged rod will be visually obvious.

True enough, it's the optiminal way to correctly determine which rod is sloppy. Since MM78 has already run the engine (I assume) without much of a deleterious effect, to save time was the only reason I mentioned this troubleshooting procedure.

Sorry took so long to respond.. The truck had to be driven about 10 or 15 miles knocking to get it home. I would have had a friend tow me but noone was avalible. So if I do the spark plug wire check thing, I don't think it will cause anymore damage then already has occured. But once I find the culprit, I pull the pan, then waht? Is my crank likely to be damaged? Can I just pull the rod cap off and put a new bearing in it?

At the point you heard Knock 1 time this is what should occur, this is for everyone, as fast as possible shut the truck/car off, then either call someone on your cell/or walk to the nearest phone, to come pull/push you home, or pick you up, if not walk , then all you will need to do is get the truck pushed/pulled/towed home, and replace a rod bearing , driving it will make you start the new motor project, that if you weren't looking to start, guess what, you just did, break out the hoist now and pull the motor.
Every time it spins knocking, more metal gets rubbed off more damage to the crank more metal getting to other places screwing other things up
