Note: Suitable coil spring compressor tools will be required for this operation.
1 Remove the front suspension strut of Fiat Punto.
2 Fit suitable spring compressors to the coli spring, and compress the spring sufficiently to enable the upper mounting to be turned by hand (see illustration).

Warning: Ensure that the coil spring is compressed sufficiently to remove all the tension from the upper mounting, before attempting to remove the piston rod nut.
3 Unscrew the nut securing the Fiat Punto strut piston rod to the upper mounting, while counterholding the piston with a suitable Allen key (see illustration).

4 Withdraw the upper mounting and upper spring seat, then withdraw the spring, complete with the compressors (see illustrations).

5 Release the lower end of the dust cover from the strut body, then withdraw the dust cover and bump rubber (see illustration).

6 With the strut assembly now dismantled, examine all the components for wear, damage or deformation. Renew any components as necessary.
7 Examine the strut body for signs of fluid leakage or damage and the piston rod for signs of pitting or scoring. While holding it in an upright position, test the operation of the strut by moving the piston rod through a full stroke, and then through short strokes of 50 to 100 mm. In both cases, the resistance felt should be smooth and continuous. If the resistance is jerky, or uneven, or if there is any visible sign of wear or damage to the strut, renewal is necessary.
8 If any doubt exists about the condition of the coil spring, carefully remove the spring compressors, and check the spring for distortion and signs of cracking. Renew the spring if it is damaged or distorted, or if there is any doubt about its condition.
Warning: Coil springs of Fiat Punto are classified by their height when under had - this is indicated by a coloured pain t marking on the side of the coil windings. All coil springs fitted to the vehicle must be of the same classification to ensure the correct ride height.
9 Begin reassembly by refitting the dust cover and bump rubber.
10 Ensure that the coil spring is compressed sufficiently to enable the upper mounting components to be fitted, then fit the spring over the piston rod, ensuring that the lower end of the spring is correctly located in the recess on the lower spring seat (see illustration).



Fit the spring ensuring that the lower end locates in the spring seat recess (arrowed)


11 Locate the upper spring seat over the piston rod, ensuring that the raised projection on the spring seat is on the same side as the swivel hub mounting bracket at the base of the strut (see illustrations).

12 Refit the upper spring seat and position it so that the pointer on the seat flange will be facing the rear of the Fiat Punto car when the strut is installed (see illustration).

13 Fit the piston rod top nut, then tighten the nut to the specified torque, counterholding the piston rod in a manner similar to that used during dismantling. Note that a suitable crows-foot adapter will be required to tighten the piston rod top nut to the specified torque
14 Remove the spring compressors and refit the strut to the car.
