drive shaft angle

[schwerdt1]

How much of an angle is safe from binding at your drive shaft and differential. When the lift was done on my truck by po, they did not angle the rear end up to keep a straight path to the tranny. And I have read that you can put in an adaptor coupling, anyone have experiance with these? Seems the easier route then turning, cutting and rewelding brackets on the rear.

what are we working on?
do you have shims on the bottom of the springs for the pinion angle?
what size lift are we talking about?

The 81 K10. Has 6" Rancho lift. Do not see shims, just the blocks.

blocks up front?

A Typical U-Joint has a working angle of up to about 15°.  That is the limit.  You still want to have matching angles at the front and rear to cancel-out acceleration changes in the U-Joints.

blocks up front?

No, shackles.

blocks up front?

No, shackles.

Unless shackles are in front(front of truck), this would point front pinion to ground, so I would if no blocks in front you have standard 6" springs, with 4" springs and 2" blocks in rear

long wheel base or standard?
either way i never head any problem with a truck only blazers and that was when a friend was trying to make a front shaft. but as long as your pinion angle is good then you dont have nothing to worry about
