Rear 4 link question

[CorneliusRox]

One other question I have is with the axle angle for the drive shaft not to bind. With a parallel 4 link the axle stays the same angle no matter what lift wouldn't that cause bind?

You just described an ideal setup for a standard two-u-joint driveshaft. That would keep the driveshaft in phase all the time.

Double cardan drive shafts are where you want the pinion to be parrallel to the driveshaft. Double cardan's can achieve greater angles than standard u-joints, but don't last as long. That's one of the reasons you see then in front axles with radius arms and not four links (typically).

He has a build thread.

You have a link to that?

thanks that helped me understand the angle much better.
