Yoke angles

What percentage plus or minus can the yokes be off in degrees from papallel. I just measured mine with an angle finder and found the rear axle(Dana 44) yoke titled up 12 deg differance from the t-case (Dana 20) yoke. I am thinking of installing degree wedges under the axle pads but the largest I have found are 8 deg, this would still leave 4 deg differance. I have lowered the t-case approx 3/4" and don't want to go any lower than that. I live in a small town without the luxury of a axle shop and the welder here, well lets say I don't want him touching my suspension.

Re: Yoke angles

A good rule is that the angles be within 3 degrees. Also follow the equal but opposite method (non CV). If you are running a CV point the yoke until its center line matches that of the driveshaft then tilt down 2 degrees for pinion climb. If you think you need a shim with more than four degrees, I would relocate the spring pads.

Re: Yoke angles

Technically U-joint angles should be within 1*of each other to avoid vibration and for maximum U-joint life the constant angle of each joint should be between 3* and 7*. The real world often dictates otherwise, but still 2* from each other and 15* constant angle each is about as far as you want to go with a standard shaft. In your case, I'm surprised that with a difference of 12* you aren't experiencing driveline vibration. How did you get such a drastic angle? Are you running REALLY long shackles? You really should relocate the brackets if you can't get the pinion angle more in line. Might be time to consider a CV shaft as well.

Re: Yoke angles

Re: Yoke angles

What're you running suspension-wise? Sounds like you're in CV-joint driveshaft territory.

Re: Yoke angles

Hey Tom, how does a "utahjeepr" end up in Southern California?
