I would rotate your knuckles. I have rotated knuckles on several different axles now and I would not do it any other way. The u joint angle is much better with the pinion rotated upwards. When you drop your driver side the pinion drops quite a bit changing the operating angle of your driveshaft ujoint. The less angle the stronger the joint. So if you start out with zero angle on the joint and flex it, your way better off then starting with 15 degrees of angle. I have to say that the driveshaft sits much happier with the pinion rotated upward.Hutch98 said:Using a D44 off o a Waggy and some say you need to rotate the knuckles others do not?

I will say do it, do it.Hutch98 said:How did you set the castor (spring perch placement)? And did you end up going with a high angle driveline shaft? And how much lift did you go with or what springs? Thanks again for the info

Hutch98 said:How do I find out the stock castor on a D44 out of a Waggy? I know the old spring perches are for a spring under the axle set up but was wondering if setting the new spring perches the direct opposite as the old ones(on the top side of the axle) if that would maintain the stock castor? Just trying to get as many answers before the big day comes.
Thanks for the info

I have u-joints at each end, with the pinion pointed at the t-case, and a square driveshaft, I get no vibes except when climbing hills and the axle wraps down, recently in the snow/ice, I had it to 50 MPH in 4wd and all I heard was the 'slapping' of the driveshaft. No vibes... It makes more noise in 2wd, or when there is no torque going to the axle (throttle or brakes), but really doesn't vibrate unless I am wheeling and going up rather steep hills under throttle.Mike said:Something I haven't really seen discussed in this thread is u-joints vs cv joints.
If you have a u-joint at each end of a driveshaft, the pinion and t-case output need to be parallel for a vibe free ride at anything more than low speed.
If you point the pinion straight at the transfer case, you'll need a u-joint at the pinion end, and a cv joint at the t-case to be vibe-free at higher speeds.

What Mike is saying is a fact, you are just a lucky SOB! Especially with a square driveshaft!!! A CV travels in a perfect circle where reg. u joints travel in an elipse...Tacoma747 said:I have u-joints at each end, with the pinion pointed at the t-case, and a square driveshaft, I get no vibes except when climbing hills and the axle wraps down, recently in the snow/ice, I had it to 50 MPH in 4wd and all I heard was the 'slapping' of the driveshaft.
