OK adjustable Control arm came yesterday. I just spend about 3 hours in the garage trying to adjust this thing to get the optimal pinion angle.... I don't know why this is kicking my butt!!!
Here is where I am now. Transmission tail stock is pointing down at 2 * ...... drive shaft is pointing down (front to back) at 5*
The rear end pinion yolk is up towards the transmission at 2*
My iPhone only does whole numbers in degrees, but I was going to go back in later with the Tremex app and get measurements as it measures to the nearest thousandth.
I think setting the pinion angle ideally for a Mustang at -2 degrees per Ford assumes you still have the stock 2 piece driveshaft so with a 1 piece driveshaft, I am not sure if that's different.
Spicer has this:
Rule 1: Universal joint operating angles at each end of a driveshaft should always be at least one-half degree
Rule 2: Universal joint operating angles on each end of a driveshaft should always be equal within one degree of each other (one half degree for motor homes and shafts in front of transfer cases or auxiliary devices)
Rule 3: For vibration-free performance, universal joint operating angles should not be larger than three degrees. If they are, make sure they do not exceed the maximum recommended angles.
I am at exactly 3 degrees operating angles with the whole number measurements above.
leave as is?
