Checking and adjusting wheel alignment Fiat Doblo 2005

Tool:

• Wheel alignment stand
• Open-end wrench 14 mm

Note: Checking and adjusting the wheel alignment is necessary to ensure good vehicle stability and handling, as well as uniform tire wear during operation. Checking and adjusting the angles of the wheels is carried out on special stands according to the instructions for their operation. The discrepancy between the actual values ​​measured on the vehicle and the reference values ​​indicated below is due to wear and deformation of the suspension parts or deformation of the body.

After installing the car on the stand (just before checking the corners), "squeeze" the car's suspension, applying two or three times a force directed from top to bottom, first to the rear bumper, and then to the front. The wheels of the vehicle must be parallel to the longitudinal axis of the vehicle.

Important: Replacing or repairing suspension parts may result in a change in wheel alignment, so checking wheel alignment is a must.

When checking and adjusting the front wheel alignment, first check the caster angle, then the camber angle, and lastly the toe-in.

Note: 

Standard 0

In this variant of the conditions, the car must be completely unloaded, the spare wheel, tools, accessories and technical fluids remain in it. The fuel tank contains 5 liters of fuel.

Standard A

In this scenario, the vehicle must be completely unloaded, leaving the spare wheel, tools and accessories in the vehicle. The fuel tank is full.

Description:

Front wheels

Front wheel alignment

1. Check the correct installation of the front wheels, according to the following factors:

• Tire pressure.
• Radial and axial runout of rims, which should not exceed 3 mm.
• Clearances in wheel bearings.
• Clearances in the hinges of ball joints.
• Clearances in the joints of the steering rods.

2. Before starting the procedure for checking the convergence of the front wheels, completely unload the car.

3. Place the vehicle on a test stand and measure distances (1a) and (1b).

Note: front wheel toe-in is checked when two variants of measurement conditions are met. 

4. Loosen the locknuts (2) (M 14 x 1.5; 85 Nm) and change their length by turning the rods.

Note: Toe-in is adjusted by simultaneously lengthening or shortening the tie rods.

5. After adjustment, tighten the locknuts.

Pitch Angle

1. Check the angle of longitudinal inclination of the axis of rotation of the wheel in accordance with the instructions of the stand.

Note: Pitch angle adjustment is not provided by the vehicle design.

2. Check the camber angle of the front wheels in accordance with the stand instructions.

Note: Front camber adjustment is not provided by the vehicle design.

rear wheels

Rear wheel alignment

1. Checking the rear wheel toe-in is performed only under conditions that comply with standard A.

2. Install the vehicle on a test bench and measure the readings.

Note: Rear wheel toe is not adjustable.

Rear wheel collapse

1. Checking the rear wheel toe-in is performed only under conditions that comply with standard A.

2. Install the vehicle on a test bench and measure the readings.

Note: Rear camber is not adjustable.

Important: if the above values ​​do not correspond to the given ranges of permissible values, then all suspension elements and mating sections of the body should be carefully checked for possible deformations.
