In automotive engineering, toe, also known as tracking, is the symmetric angle that each wheel makes with the longitudinal axis of the vehicle, as a function of static geometry, and kinematic and compliant effects.

Caster angle

The caster angle is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car, motorcycle, bicycle or other vehicle, measured in the longitudinal direction.

Camber angle

Camber angle is the angle made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of the wheels used for steering and the vertical axis of the vehicle when viewed from the front or rear.

Tire (US) Tyre (UK)

A tire (American English) or tyre (British English) is a ring-shaped vehicle component that covers the wheel's rim to protect it and enable better vehicle performance.

Technical Service Bulletin TSB

Technical Service Bulletins, or TSBs, are recommended procedures for repairing vehicles.

Torsion bar

A torsion bar suspension, also known as a torsion spring suspension (but not to be confused with torsion beam rear suspension), is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring.

Panhard rod

A Panhard rod (also called Panhard bar or track bar) is a suspension link that provides lateral location of the axle. 

Anti roll bar

An anti-roll bar (anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities.

Selective catalytic reduction SCR

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of acatalyst into diatomic nitrogen (N2) , and water (H2O).

Salvage title

In North America, a salvage title is a form of vehicle title branding, which notes that the vehicle has been damaged and/or deemed a total loss by an insurance company that paid a claim on it.
