Shock absorbers must ALWAYS be renewed in pairs, even if only one appears to be defective, in order to preserve safe handling.
Slacken the roadwheel nuts, raise the front of the vehicle and support it securely on axle stands. Remove the front roadwheels.
On the right-hand side, release the coolant expansion tank from its mountings and position it to one side
Pull the rear of the coolant expansion tank upwards to release it from the mountings
On the left-hand side, slacken the clip and disconnect the intercooler hose from the turbocharger.
Place a trolley jack under the front axle on the relevant side.
Remove the 4 nuts securing the suspension turret to the vehicle chassis
Undo the suspension turret retaining nuts
On models with ACE (Active Cornering Enhancement) undo the nut securing the ACE pipe bracket to the suspension turret, then move the bracket to one side

Release the clip securing the wiring harness to the suspension turret (where applicable).
Undo and remove the shock absorber lower mounting bolts
Undo the shock absorber lower mounting bolts (arrowed)
Manoeuvre the suspension turret and shock absorber from the engine compartment. Take care not to strain the ACE/brake pipes – where applicable.
Undo and remove the through-bolt at the top of the shock absorbers, and separate the turret from the shock absorber

Examine the shock absorber for signs of fluid leakage or damage.
Test the operation of the shock absorber, while holding it in an upright position, by moving the piston 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, renewal is necessary.
Renew the shock absorber complete if any damage or excessive wear is evident. Shock absorbers must always be renewed in axle sets, even if only one of the pair is damaged or leaking.
Inspect the mounting rubber for signs of damage or deterioration, and renew if necessary.
Refitting is a reversal of the removal procedure, tightening all fasteners to their specified torque where given.
