Setting rear pinion angle

Well, it's finally time. This upcoming weekend is when my YJ get's a new set of D44's stuffed under her. Gonna be a few weeks until she's up and running. Need to measure and order the rear CV and tierod/draglink. I don't have everything worked out yet. I'm just planning on taking it to a friend's house and setting up the axles, then working on brake and brake lines and steering and what not.

Anyway, I'm pretty sure I know how to set the rear. Just point it at the T/C output and drop it down a few degrees. How exactly do I know if it's pointed right? I have an angle finder. How is the best way to do this. and if I need to use the angle finder, where should I put it. Thanks, and wish me luck!

Now search friendly!

Re: Setting rear pinion angle

yep point that sucker at the output.. put something straight from output to rear yoke.. put angle finder on it.. should be around 20 something degrees.. measure your rear axle pinion angle.. set to match that first angle.. you can measure the rear pinion angle from the rear of the axle.. along the diff cover.. the flat ring gear side.. or across the yoke.. or on the webbing.. i like to use the diff cover.. pretty easy.. just make sure you are on top of both the bolt heads..
once you have those two angles = .. then drop the rear down 2 or 3 degrees.. i like to use 2..

Re: Setting rear pinion angle

Since I just went through this... This applies more to SOA. Take a good look at your rear spring packs to try to determine how much they're going to sag. They most likely will sag some and it will quickly eat up the few positive degrees you set in now and when you hit the throttle the pinion will go negative. I've set mine to +1 degrees and after spring sag I ended up with -4 degrees! So err on the positive side. Are you planning on building a traction bar? What sprigs are you using?
