Front suspension is an independent coil spring, ball-joint type with rubber-brushed, pivoting, upper and lower control arms. The coil springs are positioned at their lower ends on a pivoting spring seat bolted to the upper control arm. The upper end of the spring extends into spring towers formed in the front-end sheet metal. Direct, double-acting shock absorbers are located inside the coil springs and are attached to the lower coil spring seat and to the upper bracket, accessible from the engine compartment.
Each lower control arm has a strut rod running diagonally forward to a brace attached between the frame and radiator support. This strut rod provides for caster angle adjustment. Camber angle is adjusted by means of a cam-shaped lower control arm inner pivot bolt. A stabilizer rod, on station wagons, connects the two lower control arms and is rubber-mounted to the front crossmember. Front wheel bearings are tapered roller bearing.1968 and Later Chevy II and Nova
In these models, the springs ride on the lower control arms. Ball joints connect the upper and lower arms to the steering knuckle. Tapered roller wheel bearings are used.
Camber angle is adjusted by means of upper control arm inner support shaft shims.
Caster angle is adjusted by means of upper control arm inner support shaft shims.
Periodic maintenance of the front suspension includes lubrication of the four ball joints, spring seat lower pivot shafts and adjustment and lubrication of the front wheel bearings.
