Spindles

A vehicle's suspension includes a spindle. The spindle, which connects the wheel and tyre to the steering mechanism, is typically located in the front of the car, though some front-wheel-drive models also have spindles in the back. The spindle pivots between the upper and lower A-frames or on the strut. The spindle supports both the inner and outer wheel bearings, and the retaining nut at the end holds the wheel in place. The front brake calliper is typically positioned on the spindle as well.
