The relative angle of the road wheels to the true longitudinal axis of the vehicle. The toe angle is the degree of variation needed to bring the wheels into true rolling motion when the vehicle is travelling.

Basic setting of the road wheels on one axle when adjusted so that the front edges are angled very slightly inwards. Free play in the steering gear or suspension arms is taken up during forward motion to bring the wheels to a parallel position.

The difference between the angles of turn of the steered wheels when cornering. The angles are measured at 20 degrees for the inner wheel when checks and comparisons are being made. The outer wheel angle should be less than the inner wheel.

The amount that any dimension can be from the nominal size.

A widely used solvent or diluent or a co-solvent. (Co-solvents are used to help make sure the paint forms a tough, durable film). A fast-evaporating, high solvency, aromatic hydrocarbon.

A metal disc that sets the tone (frequency and volume) at which a horn operates.

The final layer of paint applied to a substrate. Several coats of topcoat may be applied in some cases.

The position of the crankshaft when the piston is at its highest position in the cylinder. The crankshaft is at 0° of rotation.

Paint for appearance and weather seal.
