Check and adjustment rear axis (collapse and convergence)
The collapse and alignment of the wheels of the rear axle are not regulated. If you detect collapse or convergence, determine and eliminate the cause. If you are detected damaged, poorly fixed, bent or worn items, they need to be repaired or replaced. If the problem is associated with the body, the body must be repaired in accordance with the specification.
1. For proper measurements when checking adjustments rear suspension It is necessary to ensure the following conditions:
- the protector on all tires must be worn uniformly and within allowable limits;
- Air pressure in both tires rear wheels must be the same;
- Rims of wheels of wheels should be in good condition.
2. Preparation of a car to verification:
- Place the cargo of 70 kg on the front seats;
- fill the fuel tank to half;
- Stabilize the springs by shaking the car on each side (especially if before this car was on the lift). If this procedure is not carried out, then the measured corner of the collapse may be too large, because The rear axle will not take its usual neutral position.
A WARNING
When used to test rotary tables that do not allow measuring the side loads, it is necessary to pre-roll back the car by 1 m backward, and then move it to 1 m ahead.
3. Measure the values \u200b\u200bof the angles using an optical instrument. The values \u200b\u200bof collapse and convergence:
- divided -z0 '± 30';
- Alignment of 1.5 ± 1 mm.
Adjusting the bearing gap of the hubs of the rear wheels
Adjustment
1. Raise the car so that the wheel that is subject to adjustment is freely rotated.
2. Remove the dustproof cap from the hub.
3. Remove the pin from the crown nut of the hub bearings. Rotating wheel or brake diskSimultaneously tighten the nut with the moment 25 n m ().
4. Loosen the nut so that you can move the stubborn puck. Checking is performed using a screwdriver: make sure not to drive and not damage the washer during the inspection ().
A WARNING
Do not rely a screwdriver about the wheel hub.
Changing the angle of installation of the wheels of all halfradus leads to:
- uneven wear of tires;
- tight rotation, power failure;
- deviation of the car of the Watch when moving in a straight line.
Noticing one of these symptoms, the owner of Hendai accent goes to go to the car service of our company. It is impossible to adjust the angle of inclination to independently: for this it is necessary to specialized equipment.
When should be adjusted
Thanks to the constant hyundai updates Accent on all indicators is in the leaders among small cars. This is not reflected at its price, which remains in the available limits, and on the need to periodically interfere with the collapse of the car.
Experts recommend visiting the auto service at least 1 time per year or when running at 12 thousand km. In the capital, these figures tend to lower due to the worst operating conditions of the car. Tuning or repair of suspension, replacement of shock absorbers, installation new rubber - All this is a reason to make the collapse of the convergence.
Saving calibration is dangerous. At any time, the car may incorrectly work in response to the actions of the driver, which will lead to an emergency.
Modern solution to the problem
By virtue of constructive features foreign cars for her does not like any other way, except the computer gathering collapse. Necessary equipment and tools are available in our company. With their help, our employees are gathering the collapse of 3D. It is the most accurate method excluding the slightest errors.
The cost of our services on the background of competitors looks much attractive, so we invite you to visit our car service. We work on a convenient schedule without days off, so we are waiting for any day of the week!
Optimal challenges and minimal wear Rubber are achieved only if the position of the wheel is properly set. With increased and uneven wear of tires, as well as the incontinence of the road - with poor stability of the direction and insufficient rotation stability, it is necessary to contact the workshop so that with the help of optical methods to set the wheel alignment.
Installation of collaboration cannot be carried out without appropriate equipment. Therefore, only the basic concepts needed to set the collapse are described here.
Convergence
The aid is called an angle to which the plane of the wheel deviates from the longitudinal axis of the car. Positive convergence means that the wheels when measuring at the height of their centers in front converge a little closer than behind. Negative convergence means that the wheels from the front differ more than behind.
W. car Mercedes. both front and rear wheels Have a positive convergence: front wheels - 0 ° 25 "(sports suspension 0 ° 10"), rear wheels - 0 ° 25 ".
Camber I. transverse slope Shkvornia swivel fist
Front axle
The collapse and transverse slope of the pile of the swivel fist reduce the transfer of the jokes on steering and provide minimal friction on turns.
The collapse call the angle to which the plane of the wheel deviates from the vertical. The front wheels are thus removed during the negative collapse at the touch point with the road further from each other than from above. At the car Mercedes front And the rear wheels have a negative collapse.
The transverse slope of the kkvornnya is the angle between the axis of turning the fist and the vertical at the point of standing the wheel, if you look in the longitudinal direction of the car.
The collapse and transverse slope of the pelvant fist together determine the so-called shoulder running. Thanks to the appropriate design data, a large stability is achieved in the direction of braking, especially if the wheels are on various road covering (for example, if left wheel slows down on dry, and right - on a wet road).
Longitudinal slope shkvorna back
The longitudinal slope of the pile back is the angle between the axis of rotation of the fist and the vertical in the transverse direction. This slope greatly affects the control of the front wheels when moving in a straight line. Minor slope favors deviations from the direction of movement when driving bad roads Or with lateral wind, and on turnings the steering wheel is poorly returned to the middle position.
The longitudinal slope together with the collapse is set using two bolts with an eccentric on the suspension levers.
Prerequisites for checking
- prescribed air pressure in tires;
- The car is not loaded, but prepared for the trip: full tank, reserve and tool - all this should be when checking;
- to preliminarily shift the suspension;
- The steering wheel is straightforward;
- adjusted backlash in the pendant levers;
- Adjusted the backlash in the wheel bearings.
Check / installing the positive convergence of the front wheels
The position of the front wheels at the sight of from above
The accurate installation of collaboration should be made only in the branded workshop. With unilateral wear, the tires must mainly be checked. Alignment is checked if parts of the steering trapezium were shot. Alignment can be tested relatively simple means.
The above prerequisites must be met.

Diagnosis of disorder Hyundai Accent. In car serviceers is carried out with computer Systems. If the car goes on poor-quality roads, the interval between the checks is significantly reduced. The reasons for urgent verification of the gathering of the car can be:
- increased tire wear rate;
- uneven erasing of the car;
- incorrect work steering vehicle;
- evasion of the Watch Car by direct direction Movement.
Before starting adjustment in the car service, the car suspension status is required. If the suspension is in a faulty state or has defects, it is impossible to carry out adjustment. First of all, it is necessary to eliminate malfunctions.
The procedure for adjusting the score-collapse will help reduce fuel consumption, and also significantly reduce tire wear rate.

Adjust the front and rear wheels HYUNDAI ACCENT
Before starting adjusting the rear axle of the car, you need to calibrate the front wheels. The design of the rear wheels does not provide a change standard characteristics collapsed, so they can only be tracked.
DDCar Car service provides quality diagnostics and adjustment services Hyundai Porter.. When contacting our service you will be pleasantly surprised affordable prices and operational service.
\u003e Check and adjust wheel installation angles
Verification and adjustment of wheel installation angles are necessary to ensure good stability and car handling, as well as uniform wear of tires during its operation. Verification and adjustment of wheel installation angles are performed on special stands according to operating instructions.
Wheel installation angles Check by car with a load of 70 kg on each front seat, with filled half fuel tank, normal air pressure in tires, in the absence of excessive backlats in the suspension nodes.
After installing the car onto the stand immediately before checking the convergence, the car suspension, applying two to three times the force 392-490 H (40-50 kgf), directed from top to bottom, first to the rear buffer, and then to the front.
Inconsistency of the actual values \u200b\u200bmeasured by car control valueslisted below can be explained by wear and deformation of suspension parts, as well as body deformation.
The angles of the installation of the front wheels:
angle longitudinal tilt The axis of rotation 1 ° 48 '± 30' the angle of collapse 0 ° ± 30 'Alignment (0 ± 3) mm
When checking and adjusting the angles of the installation of the front wheels, first check the angle of the longitudinal tilt axis of the axis of the rotation, then the angle of the collapse of the wheels and the last turn - the wheel alignment.
The angle of the longitudinal tilt axis front wheel Educated vertical and line passing through the middle top support Telescopic rack and ball support sphere fixed on lower lever. Adjusting the angle of the longitudinal tilt axis is not provided by the design of the car.
The angle of the bells of the front wheels It is characterized by the deviation of the medium plane of rotation of the wheel from the vertical. Adjusting the angle of collapse of the front wheels is not provided by the design of the car.
Annealing front wheel alignment It is an angle between the wheel rotation plane and the longitudinal axis of the car. The forward wheel alignment is regulated by changing the length of the steering.
To ensure stability and manageability rear wheels car Hyundai. Accent installed under certain corners relative to the body.
The angle of collapse of the rear wheels It is characterized by the deviation of the medium plane of rotation of the wheel from the vertical. The angle of collapse of the rear wheels is 41 '± 30'.
Adjusting the angle of collapse of the rear wheels is not provided by the design of the car.
Rear wheel alignment Adjust by changing the position of the rear transverse levers, which is achieved by the rotation of the adjusting bolts with eccentric washers. The nominal value of the convergence of the rear wheels (3 ± 2) mm.
Rotation adjusting Bolt. Clockwise increase the convergence of the rear wheels, counterclockwise - reduce. The scale of the adjusting bolt is marked after 2.4 mm (angular equivalent on one side - 14 ').
The wheels of the car must be located parallel to the longitudinal axis of the car.
