Little different question on setting pinion angle

Can you set the rear pinion angle properly by just having the rear springs setting on jackstands?

The axle I'm putting in has a different lug pattern than my old and I haven't gotten new wheels yet, so I thought about just setting the axle on the springs (SUA) with the Jeep loaded to "curb" weight on the jack stands and set the angle from there.

Will this work?

Re: Little different question on setting pinion angle

I'm sure you could,as long as you can load the suspension so it's all sitting as it will be with the tires on. But it may be dificult to get the springs and shackles to relax unless you do it with the front wheels on the groundand the rig sitting level and loaded as it will be when complete... might be a better idea not to rush it and wait for your wheels. cause I don't think you'll be able to simulate the springs position while sitting on a jackstand it will be loaded at different points.It may only make a degree or two diferance,but maybe enough to cause a vibration.

Re: Little different question on setting pinion angle

The way you want to do it will work. I set both my axles up that way. My only suggestion would be that you
make sure the center line of the axle sits off the ground as close as possible to where it will be with the new
tires and wheels mounted.

Re: Little different question on setting pinion an

I would think that you can do this. I would compensate in the front by using whatever (2x10) underneith the front to level it out. That is hub to floor and hub to floor is identical. This was what we had to do when we did alignments with the old portable Snap~On turn tables. You had to compensate for the height of the turntables to get a proprer caster reading. It should be no different for you.

But ....why wouldn't you just make sure that the rear yoke is parallel to the t-case yoke? Unless this is a cv/sye application ...the yokes should be parallel if you stand the jeep on its end ...fully extend the suspension .....or fully compress it (some minor restrictions apply)
