EXC. FIREBIRD
The front suspension is of the conventional ``A'' frame design with coil springs and ball joints. The ball joints have a ``fixed boot'' grease seal for protection against the entry of dirt and water. The steering knuckles and spindles are of integral design. On most models, an integral steering knuckle which is a combination steering knuckle, brake caliper support and steering arm is used. On other models, the steering knuckle is of the conventional type with a separate steering arm. Rubber bushings at the inner ends of the upper control arms pivot on shafts attached to the car frame. Caster and camber adjustments are made with shims at this point, Fig. 1. Direct acting shock absorbers operate within the coil springs.
