Bounty Hunter Posted January 11, 2013 Share Posted January 11, 2013 Building a front d44 for my '89 MJ, narrowing a '79 Ford hp44 to Waggy width. While I'm narrowing it, I can run the pinion up while maintaining proper caster. Anybody have pinion angle recommendations for 6"-6.5" front coils?

mvusse Posted January 11, 2013 Share Posted January 11, 2013 Angle should be such that the bottom drive shaft u joint is perfectly straight at ride height. Quote Link to comment Share on other sites More sharing options...
Bounty Hunter Posted January 11, 2013 Author Share Posted January 11, 2013 Thanks but that part I know. I'm building this axle without the drivetrain in the Jeep so I'm looking at getting the pinion in the ballpark. Quote Link to comment Share on other sites More sharing options...
mountainman Posted January 11, 2013 Share Posted January 11, 2013 what hes saying is... since its a slip joint driveshaft and has a double cardan at the Tcase... you aim the flange on the axle straight at the Tcase at ride height. :) Quote Link to comment Share on other sites More sharing options...

64 Cheyenne Posted January 12, 2013 Share Posted January 12, 2013 without being there I think it is kind of hard to say how to help without setting castor first then setting pinion after final ride height is determined. (pointed at TC output) Too many variables to do by recommendations from the board. Quote Link to comment Share on other sites More sharing options...
