pinion angle help needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am changing my 68 GMC from leaf rear to coil rear. It has stock trailing arms and 4 inch lowering coils. I need to know where to set the pinion angle before I weld the axle saddles to the axle tube. This is being done with the truck totally disassembled (body off frame no engine or tranny).

It might be hard to determine without the motor and trans in. You need to know what angle your tranny output shaft is at.

Yeap your pinion angles are dependant on one another (trans yoke and rear end yoke) here is a good resource for drivelines and installation http://www2.dana.com/pdf/J3311-1-HVTSS.PDF
