Removal

1 Firmly apply the handbrake, then jack up the front of the car and support it securely on axle stands. Remove the relevant roadwheel.
2 Unscrew the bolts securing the anti-roll bar mountings to the suspension lower arms on each side of the Fiat Punto car. Similarly, unscrew the bolts securing the anti-roll bar mountings to the front subframe (see illustrations). Allow the ends of the anti-roll bar to pivot away from the suspension lower arms of Fiat Punto.

3 Slacken and remove the nut, then withdraw the suspension lower arm balljoint clamp bolt from the swivel hub.
4 Tap a small chisel into the split on the swivel hub to spread the hub slightly, then lever the end of the suspension lower arm down to release it from the base of the swivel hub.
5 Unscrew the bolt securing the Fiat Punto suspension lower arm rear mounting to the subframe (see illustration).

7 Manoeuvre the suspension lower arm of Fiat Punto from its mounting locations and remove it from under the car.
8 With the lower arm removed, examine the arm itself, and the mounting bushes, for wear, cracks or damage.
9 Check the balljoint for wear, excessive play or stiffness. Also check the balljoint dust boot for cracks or damage.
10 The mounting bushes and balljoint assembly are integral with the suspension lower arm, and cannot be renewed independently. If other the bushes or the balljoint are worn or damaged, the complete suspension lower arm assembly must be renewed.

Refitting

Caution: Final tightening of the suspension lower arm and anti-roll bar attachments must be carried out with the car resting on its roadwheels, or damage to the rubber bushes will result.
11 Locate the suspension lower arm in its mountings. Fit the through-bolt to the front mounting bracket and engage it with the lower arm bush. Fit the securing nut, but do not fully tighten it at this stage.
12 Refit the rear mounting bolt, but do not fully tighten the bolt at this stage.
13 Engage the lower arm balljoint with the swivel hub, then refit the balljoint clamp bolt and nut. Tighten the clamp bolt nut to the specified torque.
14 Raise the anti-roll bar into position, then bolt the mounting brackets to the subframe. The anti-roll bar must be preloaded before its cuter mounting brackets can be bolted to the suspension arms. Do this by raising the ends of the anti-roll bar with a trolley jack and holding them in this position whilst the bracket mounting bolts are inserted and hand tightened. Do not fully tighten the bolts at this stage.
15 Refit the roadwheel, and lower the car to the ground.
16 Make sure that the car is parked on level ground, then release the handbrake. Roll the Fiat Punto vehicle backwards and forwards, and bounce the front of the vehicle to settle the suspension components.
17 Chock the wheels, then tighten all the anti-roll bar and suspension arm mounting nuts and bolts to the specified torque.
18 On completion, have the front wheel toe setting checked at the earliest opportunity.
