Automan2164 Posted September 7, 2009 Share Posted September 7, 2009 More than 1 degree when pointed towards the trans. Rob L. Quote Link to comment Share on other sites More sharing options...
redneck23ms Posted September 7, 2009 Share Posted September 7, 2009 if you are running a sye then you want the pinion to be pointed about 1 degree lower than the t-case output. if you're running the stock slip yoke then you pinion angle should be the same as the angle of the t-case output shaft.

Automan2164 Posted September 7, 2009 Share Posted September 7, 2009 :headpop: If you posted more info than the 1 sentance questions you ALWAYS give us, it might help. Sorry, but this has been bothering me. I don't mean to jump on ya like that, but PLEASE provide us with a little more than just one sentance. In this case, these are things that might help us really zero in on your needs: Axle? Amount of lift? What kind of suspension your running in front? Why you need to re-do the angle? Info, info, info. Rant over. Rob L. Quote Link to comment Share on other sites More sharing options...

Rant over. Rob L. the axle is a dana 35 with 6inches of lift with 3.5'' coils and 2.25'' puckets, i believe its a rough country lift (i don't know bought from a friend), and i need to redo the angle cause the lower control arms are touching the shock mount Quote Link to comment Share on other sites More sharing options...
Pete M Posted September 7, 2009 Share Posted September 7, 2009 Front axle is a Dana 30. Dana 35 is a rear axle for Jeeps. :thumbsup: Do you have adjustable control arms? Were the arms designed for the 3.5" coils and the pucks added in later? Quote Link to comment Share on other sites More sharing options...
buddy208 Posted September 7, 2009 Author Share Posted September 7, 2009 no the arms are not adjustable and we made them after the pucks were put on Quote Link to comment Share on other sites More sharing options...

Eagle Posted September 7, 2009 Share Posted September 7, 2009 :agree: Not only pictures. There are multiple angles you have to take into account with the front axle, and it usually results in a compromise. To reduce the likelihood of death wobble, you ideally want to keep the caster angle as close to stock specs as possible. But with 6 inches or more of lift, that results in an excessive u-joint angle at the pinion. So you have to start balancing out the pinion angle against the caster angle and hope you can find a happy medium that doesn't cause death wobble, yet doesn't eat the drive shaft u-joints alive.

HOrnbrod Posted September 11, 2009 Share Posted September 11, 2009 I'd also be interested in what your caster angle is. Do you have an angle finder? If so, you can take the measurement on the ball joint flat. Buddy, you have to know this stuff to make it right. :D Quote Link to comment Share on other sites More sharing options...
mvusse Posted September 11, 2009 Share Posted September 11, 2009 Those look like stock control arms to me. They are not designed to clear high angles created by lift. Most after market control arms, be they adjustable or fixed, are made in such a way as to offer more clearance on the axle end. Quote Link to comment Share on other sites More sharing options...

MrSimon Posted September 11, 2009 Share Posted September 11, 2009 Couple things .... that pinion angle is too steep. You need to flatten it out by getting adjustable uppers and lengthening them. Getting adjustable lowers and shortening them would work too, but I'm pretty sure that would pull your axle too far toward the rear of the truck. You need adjustable arms, upper and lower, for 6" of lift. You should also get drop brackets. They will greatly inmprove your ride quality and geometry. They will also fix your issue with the lowers hitting the shock bucket. If you don't' get drop brackets, do this to your shock buckets: Quote Link to comment Share on other sites More sharing options...

Eagle Posted September 12, 2009 Share Posted September 12, 2009 my dad wants me to figure out the measurement from the frame to the axle That only tells you how much lift you have. More important is the caster angle and the pinion angle. Then you need the driveshaft angle to figure out the operating angle at the pinion u-joint.
