Replacing the Wheels
To replace a wheel, proceed as follows:
Place the car on a level ground and apply the parking brake;
Prepare the jack, tyre pump, tools bag and spare wheel;
Use the combination wrench to slacken the wheel nuts one
revolution;
Insert the jack arm into the socket nearest to the wheel being
replaced (Fig. 53), and rotate the jack handle until the wheel
clears the ground (the jack should not sink in the ground
when the car is being raised);
Unscrew the wheel nuts and remove the wheel. Install the
spare wheel and uniformly tighten the wheel nuts;
Lower the car onto the wheels, and withdraw the jack;
Tighten the nuts to a torque of 70-90 N·m (7-9 kg m), check tyre inflation pressure and bring
it to normal;

Front-End Alignment
Every 20,000 Km (and also after the first 2,000-3,000 Km if the car is new) as well as in
case of rapid and irregular wear of the front wheel tyres and impaired steering of the car,
check the front-end alignment. It is advisable that this operation is performed at a service
station equipped with a precision optical stand ensuring high-accuracy checking and front-end
alignment. Given below is a method, though less accurate, of checking only the wheel camber
and toe-in by the Owner himself, on condition that the following requirements are met:
Tyre inflation pressure is normal;
Radial and axial runout of the front wheel rims does not exceed 3 mm;
End play in the front wheel bearings does not exceed 0.15 mm;
Backlash in the steering worm- to-roller mesh ensures a steering wheel play not exceeding
5"; there is no clearance between the idler arm shaft and shaft bushings;
The rubber elements in the joints of the front suspension wish- bones have no ruptures and
ultimate distortions;
Shock absorber rods are not jamming; there are no excessive clearances in the steering rod
ball joints and in the ball supports of the front suspension wishbones.
Check the wheel alignment with the car in the running order, with a load of 3,200 N (320 kg)
which roughly corresponds to the weight of four persons plus 400 N (40 kg) of luggage in the
luggage compartment. Place the car on a flat level ground and set the front wheels in the
position that corresponds to the straight-ahead motion.
