need a question answered with a quickness please!
the car is not on 100% level ground. turns out if i put the angle finder on the ground there is a -3* slope. (which since i have been setting pinion angle on said slope im obviously off some since i never bothered to check it before.
well if i raise the car on jackstands (of course the rear end needs to be supporting the weight on the rear and i have jack stands up front.
does the body need to be level for me to accurately set the pinion angle and tail shaft angle? (say if i put the angle finder on my subframe connector in the center of the car should it be at 0*?)
