aLock the slip plates of the lift.
aPosition the vehicle on a lift (see Vehicle: Towing
and lifting) .
aCheck the condition of the following components:
-track rods,
-axial ball joint linkages,
-subframe,
-lower arm rubber bushes,
-lower arm ball joints (see Front driveshaft lower
arm ball joint: Check) ,
-shock absorbers,
-tyres,
aCheck:
-the tyre size (see 35A, Wheels and tyres, Tyres:
Identification, page 35A-7) ,
-the tyre inflation pressure (see 35A, Wheels and
tyres, Tyre pressure: Identification, page 35A-
10) .
aPut the vehicle in the VODM position (vehicle in run-
ning order) (see 30A, General information, Under-
body heights: Adjustment value, page 30A-24) :
-tank full,
-vehicle empty (without luggage, etc.).
aConsult:
-the front axle geometry values (see 30A, General
information, Front axle assembly: Adjustment
values, page 30A-31) ,
-the rear axle geometry values (see 30A, General
information, Rear axle assembly: Adjustment
values, page 30A-38) .
aRefer to the user manual for the geometry tester.
aCheck the geometry using the geometry tester.
aIf there is an inconsistency between the manufactur-
er's values and the measured values:
aAdjust the front axle (see 30A, General informa-
tion, Front axle system: Adjustment, page 30A-
36)

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aSet the wheels straight ahead.
aRemove the front wheels (see 35A, Wheels and ty-
res, Wheel: Removal - Refitting, page 35A-1) .II - REMOVAL OPERATION
aRemove the retaining spring (1) using a wide, flat-
blade screwdriver.
aMark the position of the cap on the base of the shock
absorber using a indelible pencil.
aUnclip the cap from the base of the shock absorber. Special tooling required

IMPORTANT
To avoid all risk of damage to the systems, apply
the safety and cleanliness instructions and opera-
tion recommendations before carrying out any
repair:
- (see Front axle components: Precautions for
the repair) ,
- (see Vehicle: Precautions for the repair) (01D,
Mechanical introduction).
