Advice 1: How to check the rack VAZ 2109

For normal and safe operation of the vehicle is required to conduct periodic maintenance. Faulty struts directly affect the safe operation of your vehicle, so be sure to check their status.

Checking the condition of the spring strut is simple, and can hold their own. Modern telescopic struts are sealed, and therefore when defects are detected they are replaced.

Check in motion

Initial validation of the struts of the car VAZ – 2109 carried out "by ear", when driving on a rough road. Extraneous knocks in the area of racks or "breakdown" suspension show their faults.

The faulty rack is replaced with a pair/

If the front or the rear of the car much swinging or as they say, "dancing", it also means that the dampers have failed and should be replaced.

The basic test

A further test is carried out with the vehicle stationary. This requires strong pressure on the body above each bar. The normal racks car should make no more than one oscillatory motion.

Next, conduct an external inspection of all racks. Working on the shock absorbers should be of the flows of liquid, any damage or deformation. Then check out the spring struts for cracks or damage.

If the suspension is continuously triggered until the stop "breaks", it means that the springs have worn out and must be replaced. To operate such a car is impossible, because you can deform the body.

Then check the condition of the cups the springs for cracks or deformation. Damper compression must also be an integer and should not have mechanical damage.

Before disassembling the strut, you must compress the spring puller/

Taken from the vehicle strut Assembly to be disassembled and a thorough inspection and Troubleshooting. Shock struts should be dry and clean, without any traces of wear. Before installing the shock absorber must be checked.

Test ride of the stock shock absorbers held in a vertically mounted rack. In the bottom hole for the mounting bolt to insert a large screw driver, step on it and pull the stock up or push down. On a good absorber rod moves smoothly, without jamming or failures.

When checking the thrust bearing it should spin easily and silently, and also not have cracks or damage. Worn out dampers need to be replaced.

Advice 2: How to change rear struts on VAZ 2109

Drive the car with faulty shock absorbers is fraught with fast wear of tires, hub bearings, suspension parts, and, in addition, can cost you your life in a significant increase in stopping distance.

Car suspension, shock absorbers

Since the invention of the first cars their design was constantly improved and become more complex. The original cars had leaf spring suspension, but gradually manufacturers added additional elements, both mechanical and hydraulic, pneumatic and even electric. Allowing currently to make drive more comfortable, as well as to increase its manageability and security.

An important role in the suspension of vehicles play the absorbers. They were invented in the last century and made a splash in the automotive industry. During the trip they dampen vibration on rough roads and provide her with a better grip.

Resource absorbers, replacing conditions

But, like every detail and mechanism of the car, the shock absorbers have a comprehensive resource. The average is from 30 to 50 thousand km mileage of the car, and the more they serve is extremely rare. In fact, a lot depends on the manufacturer of shock absorbers, quality, riding style. For verification it is recommended to either refer to the service employees or to perform a series of simple steps.

The rack should be replaced if you find them drips oil, a knocking in the suspension when driving (with the condition that all other suspension parts are OK). You can also do this test: wiggle the car to make sure that the shock absorbers dampen vibrations. However, the latter action can only detect completely non-functional details.

Replacing rear struts on VAZ 2109

So, you found that on your domestic VAZ 2109 it is time to replace the rear rack. If you're not going to trust the professionals from auto repair, to prepare necessary tools, Jack, and, of course, you should buy new struts. Change them in pairs, since one axle they should be identical. In addition, may need new supplies to replace the old, namely, the set of upper bushings or buffers.

Originally from the top of the trunk should remove the cap from the strut. Then applied two keys – one unscrews the nut, the other holds the strut shaft so it cannot rotate. The next step, Unscrew the nut from the bottom of the shock absorber in place of its attachment to the bracket of the rear beam. For a complete dismantling of the rear shock absorber beam is pressed downwards, which gives the opportunity to take it out.

Then you need to remove the rubber gasket from the Cup top mount Assembly, the dust cover of the shock absorber from the spring and buffer. In violation of the integrity of rubber parts of the shock absorber should be replaced.

Upon completion of the above steps, you are ready to build and install the new shock absorber. For this purpose, the absorber is fully pulled out the stem and it fixed the buffer, dust boot and metal cover. Also once the stock breaks through and nut. The shock absorber is attached to the bracket of the rear beam and it puts a spring. Further, any existing key sticking in the nut, the strut shaft is extended over the entire length. When the stock is out, Unscrew the nut.

To compress the springs under the back beam is mounted the Jack. Its slow lifting will pull the spring, will only guide the piston rod in a mounting opening and secure it with the nut. In the same manner, changing the second rear shock.
