How do I adjust this thing?

Do I put the angle finder on the driveshaft and see what the reading is then move it to the arm itself and then adjust accordingly?...

Thanks.

you want the weight of the car to be on the tires for an accurate reading, then if the angle finder has a magnetic base, we usually stick it on top of the pinion yoke where the driveshaft bolts into.

Just purchased and installed the torque arm. According to the directions: "Using an angle finder place it on the driveshaft (flat smooth spot) and record the angle indicated. Next, place the angel finder on the flat surface where the torque arm mounts to the rear end (this surface is parallel with the pinion shaft) record angle indicated."

You subtract the pinion angle from the driveshaft angle to get your "true" pinion angle.

For better bite you need to run negative true pinion angle.

Hope this helps.

Don't match the driveshaft! I have posted this seveval times- maybe mods should post a sticky link or something.

part 2- different ride height examples.

So if I read that correctly I have to remove the tail shaft off my tranny to get the correct angle from the out put shaft?

That might be easy to do with an automatic tranny, but it's not going to happen with a manual tranny, especially with the T-56.

Look, its a basic example of what has to be gauged-HAS TO- no ands ifs or buts. What ever your method- the output shaft angle must be taken. Then with the car chassis at the same angle (with the rear axle loaded already) you the match the pinion angle to the outputshaft angle THEN drop the front of the pinion 1* more.

Use an extra yoke without the u-joints installed (drop a square from the u-joint mount angle and gauge underneath, Ect.- be creative- not my problem how you do it, but it NEEDS to be gauged.

geeeez, no need to be touchy. Thanks for the info.

Why is it that all the manufacturers installation sheets that I've seen say to reference the driveshaft if its so wrong?

Hey, is there any way Spohn could jump in and clear up the confusion on setting the pinion angle? Do you use the drive shaft angle as reference or not?

Thanks,

The front driveshaft to yoke angle and the rear driveshaft to yoke angles have to be as close to match as possible to cancel out harmonics. If they do not cancel eachothers angles then things will vibrabate and wear much faster (aka the waa-waa's)
