? for anyone that\'s done a YJ front D44 upgrade

Ok, I've done a test fit for my front SOA HP 44 with new 2" BDS springs. My knuckle yokes haven't been put on yet, so I can still set my caster.

With 4* shims up front, my pinion is at 10*, drive shaft is at 11.5*, and my T/C yoke is at -7.5*. That gives me 19* at my TC. I was planning on using a CV set-up.

Is 19* too much for a CV?

Also, I'm planning on setting my caster to 7*, with my pinion tilted at 10*. Any thoughts/experiences?

FYI, my jeep will now sit at 25.75" center of hub to the bottom of the flare. Should give me plenty of clearance for 35's.

Thanks!

Re: ? for anyone that\'s done a YJ front D44 upgrade

tho i have not done this exact setup... i have used a normal d44.. and have set them at 10 degrees... so i was thinking 10 for you might be a bit much... i always want my front pinion pointing a few degrees lower than the front output of the transfer case... (not pointing right at it.. but lower)... since under torque.. that front pinion will want to climb on you..
7 degrees sounds good... especially if you ever plan on going larger than 35's.. anything between 4-8 will work great..

Jeepgod, What spring lift (how many inches) did you use with your 10*. Any CV binding issues? Do you know your driveshaft/TC yoke angle?

Although my set-up above doesn't conform to this statement,
I always thought you wanted the front pinion a few degrees higher than the drive shaft.

Since the frnt pinion is located on the rear of the front diff, and its torque response is the same as the rear, the front pinion will want to move down, and the rear will want to move up. I know that, like you said above that you do want the angle slightly lower in the rear.

Thanks for the info!
