Pinion Angle, how to find it.
« on: June 04, 2008, 06:24:47 PM »
I always thought you measured the angle of the driveshaft and the measure of the rearend.

Well this transmission site says to measure the angle of the rearend, and instead of the driveshaft it says measure the angle of the transmission?

Here is the site, what do yall think?

While ideally you would want the entire drivetrain to be perfectly straight when under hard acceleration, making the output and pinion the same angle means nothing unless the driveshaft in between is in line.

Brian that's what I thought, you want it all to be lined up when all the power is applied?

So if you check the driveshaft and get it at the right angle in relation to the rearend, right?

The old pinion angle debate.  It always makes for some interesting threads over on moparts.

never run the driveshaft straight.........measure driveshaft and pinion, to get pinion  angle,you need neg. angle at rest......1-8 degrees neg. are figures you`ll usually see, depending on suspension type.....4-link race type, with rod ends,needs very little......leaf spring type suspensions, wrap up, and therefore need more, these are a couple examples. :D

Engine angle and trans angle should be the same so you can measure off of the harmonic dampner, engine plate, mid plate, etc. Then measure the pinion for the down/ negative angle.

5-10; down for leaf spring
2 down for leaf link
1 down for labber bar
Mopar to ya!!
