Front suspension — design description (Mazda 121 (3))

The front suspension uses two MacPherson shock absorber struts (1), which in turn consist of a coil spring and a built-in gas shock absorber. The struts are mounted at the top on the body and at the bottom on the steering knuckles (2). An L-shaped transverse suspension arm, which is connected to the steering knuckle via a ball joint (support), provides lateral direction. The transverse arms are connected with bolts through rubber supports to the auxiliary frame (subframe) (4), which is attached to the body at six points.

The anti-roll bar (5) is connected via two connecting rods (6) to both shock absorber struts. The anti-roll bar is secured to the auxiliary frame (4) using rubber supports. The anti-roll bar reduces the body tilt when cornering.

The engine torque is transmitted to the front wheels via two drive shafts. Both drive shafts are the same length and have two constant velocity joints (CV joints). Between the right drive shaft and the gearbox flange is an intermediate shaft, which rests on the auxiliary frame of the front axle.

The front wheel bearings are non-separable and must be replaced after each removal.

Specially for Ford KA

The transverse levers are bolted to the body via rubber supports and additional holders. There is no auxiliary frame for the front axle. Both drive shafts are non-separable, and the right shaft is significantly longer than the left. To compensate for the vibrations of the right, longer shaft, a balancing weight is installed on it.

Precautions: Welding and straightening work on the load-bearing and guide parts of the front suspension is not permitted. Self-locking nuts, as well as corroded bolts/nuts, are always replaced in the event of repair.
