The Chevrolet C10 pickup truck was a half-ton, lightweight two wheel drive model which first appeared on the market in the 1960s. Featuring an independent front suspension, the C10 was not meant to be used as a work vehicle. Instead, this lightweight truck drove more like a car than a truck. Nevertheless, performing a wheel alignment on your Chevy C10 is a simple process once you know the recommended angles for the wheels.
Understanding Alignment Specs
Wheel alignment of any vehicle consists of adjusting the angles of the wheels so that they are all parallel to one another and perpendicular to the ground. The main variables involved are the camber, caster and toe. The camber is typically adjusted so that minimum tire wear occurs at different speeds while in motion. The caster is responsible for straight line tracking while driving. Finally, the toe varies based on the speed at which a vehicle is travelling. Therefore, a toe is usually adjusted so that it equals zero when the vehicle is travelling at a high speed. All of these variables must be considered when performing a wheel alignment.
For total toe specifications, the minimum toe for the front end of the 1971 Chevy C10 truck should be +1.81 degrees, and the maximum should be +3.77 degrees. The before toe should be +15.30 and the after toe should come in at +2.70 degrees. The caster should be at a minimum of +2°30' and has a maximum of +3°30'. The camber angle should be at a minimum of -0°30' and a maximum of +0°30'. The partial toe should be +1.40. The setback should be -0°14'.
For the rear specifications, the 1971 Chevy C10 should have a total toe measurement before of -1.90 degrees, and after adjustment have a toe of -2.00. The camber angle for the rear should be -0°38' and the partial toe should be +1.60. The setback needs to be -0°15' and the thrust angle needs to be +0°21'.
