1 General information
Front suspension The front suspension is independent, comprising transverse lower wishbones, coil spring-over-damper strut units and an anti-roll bar. The hub carriors are bolted to the base of the stmt units and are linked to the lower arms by means ot balliotnts. The entire front suspension assembly is mounted on a subframe, which is In turn botted to the vehicle body.
Rear suspension The rear suspension incorporates a torsion beam axle, trailing arms, coil springs and separate telescopic dampers. In addition, a rear anil-roll bar is fitted to certain models. The components form a discrete sub-assembly which can be unboiled from the underside of the vehicle separately or as a complete unit.
Steering The two-piece steering shaft runs in a tubular column assembly, which is bolted to a bracket mounted on the vehicles bulkhead. The shaft Is articulated at its lower end by means of a universal Joint, which is clamped to the steering shaft and the steering gear pinion by moans of clamp bolts. The steering gear is mounted on the engine compartment bulkhead, and is connected to the steering arms projecting rearwards from Ihe hub carriers. The track-rods are fitted with balljoints at their inner and outer ends, to allow for suspension movement, and are threaded to facilitate ad|ustment. Hydrauiically-assisted power steering ts fittod to some models. The hydraulic system is powered by a belt-driven servo pump, which is driven from the crankshaft pulley.
Certain models are fitted with an airbag system. Sensors built into the vehicle body are triggered in the event of a front end collision and prompt an Electronic Control Unll (ECU) to activate the airbag, mounted In the centre of the steering wheel and the facia. This reduces the risk of the front seat occupants striking the steering wheel, windscreen or facia during an accident.

A


Warning: For safety reasons, owners are strongty advised to entrust to an authorised Flat dealer any work which involves disturbing the airbag system components. The airbag inflation devices contain explosive material and legislation exists to control their handling and storage, in addition, specialised test equipment Is needed to check that the airbag system Is fully operational following reassembly.
2 Front hub bearings -renewal *
Note: A balljoint separator tool, and a press or suitable alternative tools (see text) will be required for this operation. The bearing will be destroyed during the removal procedure.
Removal 1 Chock the rear wheels, apply the handbrake, then jack up the front of the vehicle and support on axle stands (see Jacking and vehicle support). Remove the appropriate roadwheel. 2 Remove the brake disc and caliper, with reference to Chapter 9. Note that the caliper body can remain bolted to its bracket: there is no need lo disconnect the brake fluid hose from the caliper. 3 With reference to Chapter 8. slacken and remove the driveshaft hub nut. 4 On models with ABS, unbolt the ABS wheel sensor, and remove the screw securing the
ABS sensor wiring to the hub carrier. Suspend the sensor away from the working ares, to avoid the possibility of damage. 5 With reference to Section 17, separate
th»
track-rod end from the hub carrier, using
a
suitable balljoint splitter. 6 Remove the two nuts from tho botts securing Ihe hub carrier to the base of th» suspension strut (refer to Section
3).
Withdrew the bolts and separate the top of hub earrtt from the strut. 7 Disconnect the outboard end of Ito driveshaft from the hub, as described durirg the driveshaft removal and refitting procedm in Chapter 8. Note: There is no naod fo disconnect the Inboard end of the
drivestett
from the transmission. Caution: Do not allow the end of tin driveshaft to hang down under its
own
weight, as this places strain on the
CV
joints; support the end of the shaft uskg wire or string. 8 Slacken and remove the nut and clamp bolt, then push the lower arm down anc separate the balljoint from the base of the tab carrier (see illustrations). 9 At this stage, it is recommended that
the bub
carrier be taken to a engineering workshop,
as
the hub and bearing should ideally be removed from the hub carrier using a hydraulic press

2.10 Using a slide hammer to extract the hub 2.11 Wheel bearing components / Hub carrier 2 Wheel bearing 3 Circlip
Owners wishing to attempt the work them-
selves
should proceed as follows. 10 Mount tho hub carrier firmly In a bench vice. Attach a slide hammer to the hub flange and extract the hub. together with the inner bearing race, If it has remained attached to the hub. Unbolt and remove the heat shield
(see
Illustration). 11 Mount the hub carrier horizontally in the rice, then remove tho bearing retaining circlip. Using a suitable length of tubing as a drift, drive Ihe bearing outer race from the carrier (see Illustration). Note that a flange on the outboard side of the carrier means that the bearing can only be driven out in one direction. 12 Support the inner bearing race, if it has remained attached to the hub, then press or drive the hub from the race. Alternatively, pull trie bearing race from the hub using a suitable Iw or three-legged puller. 13 Before Installing the new bearing, thoroughly clean the bearing location in the tub carrier. U Fit the new bearing from the Inboard side the hub: press or drive the bearing into position, applying pressure only to the bearing oiler race. Oo not lubricate the mating surface
ol the
bearing In an attempt to ease installation. 15 Fit the bearing retaining circlip to its 700ve in the hub carrier, then refit the heat
shield and tighten the retaining screw securely. 16 Support the outer face of the hub carrier across the jaws of a bench vice. 17 Carefully press or draw the hub into the bearing, noting that the bearing inner race must be supported during Ihis operation, to prevent It from being separated from the outer race. This can be achieved using a suitable socket, threaded rod, washers and a length of bar (see Illustration). 18 On completion, check that the hub rotates freely in the hub carrier without resistance or roughness.
2.17 Typical method of drawing the hub into the wheel bearing using improvised tools
Refitting 19 Reconnect the outboard end of the drive-shaft to the hub as described In Chapter 8. Ensure that the driveshaft nut is tightened to the correct torque and adequately staked. Ideally, for safety reasons due to the very high torque of the driveshaft nut, carry out final tightening and staking of the nut after refitting the roadwheel and lowering the car to the ground. 20 Reconnect the hub carrier to the lower arm balljoint, then fit a new clamp bolt nut. Tighten tho nut to the specified torque. 21 Engage the hub carrier with the suspension strut, then refit the securing bolts and nuts, tightening them to the specified torque. 22 Reconnect the steering track-rod balljoint to the hub carrier steering arm. Use a new nut and tighten it to the specified torque. 23 Refer to Chapter 9 and refit the brake disc and caliper. 24 Where applicable, fit the ABS wheel sensor into its mounting hole and tighten the securing screw. 25 Refit the roadwheel, and tower the vehicle to the ground. 26 Have the front wheel alignment checked by a Fiat dealer or a tyre specialist at the earliest opportunity.
