14bff pinion angle

[SkulzNBonz]

The search feature is seriously lacking. I am in the middle of installing my 14 bolt, and I would like to know the pinion angle I should shoot for. I know it's supposed to be within a couple degrees of the t-case output, or just to the opposite direction. I am running a standard driveshaft, and probably will for a while. Could someone give me a clear answer befroe I tack weld my spring perches in place? Thanks, and sorry for the question that has been answered more than once here.

Measure the angle at the transfercase output shaft. You want to match it (but opposite) minus a degree or two for axle wrap under torque.

For a street-driven truck, that is the best advice.

For a trail rig, point the pig directly at the t-case and glue it!

The onlt time you point the pinion at the T-case is when you're running a CV driveshaft. Anything other than a CV shaft the driveline needs to have the same working angles front and back otherwise you will get a vibration and pre-mature U-joint failures.

That's why I said for trail rig only. High-speed vibration doesn't matter at low trail speeds.

That's funny Daniel, I just thought aboot calling and asking you, for "some" reason I knew you would know Thanks for the quick answer, y'all. My rig sees the pavement, and I drive my rig to the trail, so it needs to be right for both the trail and the street.

Who said anything about high speed vibration? You will usually get a vibration at low speeds and get worse with the faster you go.
