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 bearing (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 sealed bearing.
The brake disks are ventilated.

REMOUNTING

REMARK :
Ensure the presence of the protection plate (A) on the suspension ball joint axle.

Perform the operations in the following sequence:

− Arm attachment on the power train support without tightening to the required moment

the axles nuts (3) .

− Ball joint mounting in the steering knuckle
− Attachment of the ball joint screw and tightening its nut to the required moment ;

Mount the wheels, tighten the screws to the required moment, and then with the vehicle on

wheels, continue with:

– Remounting the anti roll bar by tightening to the required moment the attachment screws.
– Tightening the shaft arm nuts and fixing the strap (straps) – (4) to the upper part, by

tightening the screws to the required moment.

REMARK :
When remounting the attachment buffers on the anti roll bar, put inside them 1 g of

grease type MOYKOTE 33 MEDIUM.

When remounting the suspension arm axles, use new self-locking nuts.
