Thanks for the tips guys:U:

no problem anytime.

I wasn't saying that lifting the vehicle would throw a driveline out of phase at all. I was saying that driveline angles don't change as drastically as with a Jeep due to its long length. When you set up a driveline, your u-joint angles have to be equal and opposite in order for them to properly compliment each other. You don't have a joint at 3* drop coming out of the T-Case, and 0* going into the pinion... It has to match that 3*. When you lift a vehicle, you throw those angles off. In a jeep you can change them 10*-15* pretty quickly, but with these trucks it would take a much taller lift to duplicate that. Is what I'm saying making sense? It is in my head, but I've been doing this a while and I just have a bit different lingo.

i got ya when i read it i didnt think about pinion angles, i thought you were still talkin about Phasing. i have a jeep too, that i wheel currently motor less. yea my 13" drive shaft has bad problems with the rear u joint i have the rear pinion rotated up so it is straight with the drive shaft to avoid the yokes biding going down steep hills but it still wears them badly.

Well, unless you have a double cardan joint on the T-Case end (a lot of guys call it a CV, even though its not), you don't want the pinion pointed at the T-Case. That's the problem with Jeeps, the driveshaft is so short that to keep angles equal and opposite, the U-Joints would bind. The easiest solution is a Double Cardan driveshaft... The only other real option is to stretch the wheelbase, or tilt the engine down.

If this truck has a lift on it and no pinion angle shims in the rear axles I can guess what the problem is.

its a budget wheeler so i just swap to an extra drive shaft when i break one. i dont want to spend the money on an sye kit and a new drive shaft anyways cuz it is blown up right now and i am trying to save money up to swap a 4BT in it.:U: then i will turn the lil banger up and roll the coal with it.

Nasty, i got a friend putting a 4bt in a wrangler, I have pictures of the engine in my profile of the ruff instal....got the motor out of a box truck.:U:
