Swap Out Rear Springs




Removing ( Refitting ) Rear Springs

- Position the vehicle on a lift.

1. Place a hydraulic lift under the rear crossmember by the spring.

2. Undo the bolt securing the shock absorber to the suspension crossmember.

3. Slowly lower the hydraulic lift until the spring is not compressed and remove it.


Do the same for the right spring.



Refitting New Springs
- Place a hydraulic lift under the rear crossmember by the spring seat.

- Place the spring in its housing.

- Raise the hydraulic lift slowly until the shock absorber lower mounting is in line with its housing in the crossmember and then secure it tightening the bolt to the recommended torque.

Bolt Is M12 Tightened To 11.7 ÷ 14.3 daNm


- Slowly lower the hydraulic lift until the spring is not compressed by the lift.


Do the same for the right spring.

Swap Out Front Springs



Swap Out Front Springs

- Put up on lift and remove wheels.

1. Undo the bolts securing the shock absorber to the steering knuckle.

2. Undo the nut (2a) and disconnect the anti-roll bar joint (2b) from the shock absorber.

1. Undo the nut (1a) and the mounting (1b) and remove the shock absorber and spring assembly (1c).


Before undoing the nut (1a), insert the spanner correctly right into the hexagonal groove at the top of the shock absorber stem.



1. Fit the spring compressors onto the springs and compress until the spring moves freely within the casing at either end.

2. Undo the nut (2a) and remove the buffer (2b).

- Discharge the spring and remove the shock absorber-spring assembly from the tool.

Front4.JPG
1. Remove the dust cover (1a), the spring (1b) and the end of travel buffer (1c) for the shock absorber (1d).

Refitting ( Removing )
- Assemble the end of travel buffer, the spring and the dust cover on the shock absorber.

- Compress the shock absorber and the spring using the tool.


Dismantling/ reassembling front suspension shock absorber



- Tighten the nut securing the end of travel buffer to the shock absorber to the recommended torque.3.6 ÷ 4.4 daNM



Front shock absorber to end of travel buffer


- Remove the spring compressor from the spring.


Dismantling/ reassembling front suspension shock absorber



- Place the shock absorber assembly in its housing.

- Provisionally screw in the nut securing the shock absorber to the bodyshell without tightening it.

- Connect the anti-roll bar joint to the shock absorber and tighten the nut to the recommended torque 3.6 ÷ 4.4 daNM.


- Tighten the new bolts fixing the shock absorber to the steering knuckle to the recommended torque.


To tighten to torque, position the torque wrench on the nut and not on the bolt.

Bolt (to be replaced)

M12

10.3 ÷ 12.6 + 45°


- With the vehicle on the ground, tighten the nut securing the shock absorber to the bodyshell, screwed in previously, to the recommended torque.

Recomended Safety Test's



Recomended Safety Test's
arn - Contents

- Carry out a road test on traffic free roads in safe conditions following the highway code.

- Before proceeding with the test, check the inflation pressure of the two vehicles, restoring the values to the correct ones if they are found to be incorrect.

- Also check the conditions of the wheel rims making sure they are not distorted or broken, replacing them if any faults are found.

- Carry out the test on an uneven road surface, at a speed of 40 km/h to check the capacity of the suspension to absorb the stresses produced by small imperfections (suspension damping) with the consesquent acoustic repercussions inside the passenger compartment.

- Check the capacity of the suspension to absorb the stresses produced by large imperfections and the consequent acoustic repercussions inside the passenger compartment, carry out the road test at a speed of 40 km/h over a route that has a series of pot-holes.

- Check the rapid damping of any pitching produced by the irregularities in the road surface, carrying out the test at a speed of 50 km/h on a straight road with suitably spaced humps and holes.

- Carry out a road test on traffic free roads in safe conditions following the highway code.
- Before proceeding with the test, check the inflation pressure of the two vehicles, restoring the values to the correct ones if they are found to be incorrect.
- Also check the conditions of the wheel rims making sure they are not distorted or broken, replacing them if any faults are found.
- Carry out the test on a route where there are left and right hand bends of different degrees, evaluating the laying down speed of the vehicle round the bends, trying to take the bends at a constant speed, avoiding carrying out pull/release manoeuvres.


Now take a good luck at your new lowered baby.
