U-joint question
U-joint question
(OP)
With a larger U-joint will I be able to run it at a higher angle? Or with the larger joint comes a larger yoke and these cancel out any angle gains? This vehicle will not be run on the road so speed and vibration are not of great concern. I know the higher the angle the shorter the life, I have no problem doing the maintenance or buying a new joint once in a while. As long as the shaft doesn't bind, I'll be happy.

RE: U-joint question
The truck originally had a double cardigan joint, what you are calling a "CV" I had to take it out after the lift was installed. I got better results with a single u-joint at each end of the drive shaft. The "CV" joint sticks out from the transfer case roughly 6" and the total length of the shaft is maybe 20". If I was going to use the "CV" I would have to cut and turn the knuckles on the axle, and thats not something I feel like tackling right now.
I'm not sure why, but the GM 1ton that I got the axle out of was not lifted and didn't use a "CV" joint either. Why was it used on 1/2tons??

It may not be easy to find in the sizes you would need, and replacing the stock cardan joints with the ball-knuckle fwd style joints could be a lot of work.
I suppose the type of u-joint selected would have a lot to do with the vehicle's sensitivity to any driveline torsional exitation, and how likely the occupants are to notice the results of it.
