The links attach to the vehicle with bolts and bushings
at their inner pivot points and to the steering knuckle,
which is part of the front wheel spindle, at their outer
points.
The knuckle is mounted to the upper and lower links
each of which has a ball joint to permit pivoting of the
knuckle for steering operations. The hub is supported
in position on the knuckle spindle by means of the two
bearings and the rotor is mounted on the hub.
The front suspension is an independent type utilizing
torsion bar springs (4 ×4, 4 ×2 (High ride suspension))
and coil springs (4 ×2 (except High ride suspension)).
The torsion bar spring has splines on each end. Height
control is provided on the third crossmember. Both the
upper and lower links are pressed steel and the torsion
bar is supported at the ends by lower link in front and by
height control arm in rear.
