UPPER CONTROL ARM AND MOUNT (CONT.)
ADJUSTING PINION ANGLE WITH AN ADJUSTABLE UPPER CONTROL ARM
Make sure the rear end is loaded by either setting the car on the ground or letting the car rest on jack stands
positioned under the rear axle. In both cases, the car needs to be as level as possible and the suspension loaded.
• Place an angle finder on the rear portion of the two piece driveshaft and record the angle. Now place the angle
finder on the pinion yoke and record the angle.
• Subtracting one angle from the other results in your pinion angle (Example: -2 rear end angle subtracted from 0
driveshaft angle = -2 degrees)
• Adjust the control arm to achieve the desired angle.
• As a starting point, most cars respond well to the following initial settings: Automatics: 1-2 degrees negative,
Manuals: 2-3 degrees negative
• Once pinion angle has been set, apply Loctite to jam nuts and tighten.
