DISMOUNTING
Dismount the two maintaining collars

Remove as much grease as possible.
Mark one of the groove routes of the shaft

Ensure that retaining star arms are correctly
positioned in the shaft marks. Check by hand, the joint operation.

CHARACTERISTICS
The front axle is composed of two joint half axles with independents wheels, designed for the
suspension type Mc.Pherson.
The joints of front half axle arm are done by means of an elastic bear ing (chassis side) and
by means of a suspension ball joint (wheel side)
The transmission of the motion to the wheels is done by means of two planetary axles, not
equal, with homocinetic tripod joints.
The wheel hub is assembled in the steering knuckle by means of a preset and sealed
bearing. The brake disks are aerated.
