Replacement bearing front hubs of VAZ-2109 with his own hands

Replacement bearing front hubs of VAZ-2109 carried out in case of wear and tear. From this material you will learn what the signs of failure have wheel bearings, how to conduct a repair yourself, without resorting to the services of specialists per HUNDRED. To focus, of course, the emphasis is on “white” methods and “black” to give preference not need. They are too dangerous – and possible injury to, and the hub to break. But of course, they will be considered briefly.

Signs of bearing failure

To Start, of course, necessary with, what are the external signs of failure of the bearing. Because you need to accurately determine whether you need to replace it. Immediately need to mention – option to confuse the signs with the damage to any other suspension or drive there. To start with the fact that there is a terrible howl when driving. And with increasing speed it becomes louder and louder.

When riding in a car with a broken wheel bearing will feel like being in a plane that is gaining speed and is about to take off. Perhaps this is the main external symptom of damage. To completely verify this, you will need the wheel and pull his hands sharply. If there is a backlash, a feeling that the hub is "goes", then there is a bearing failure. Of course, maybe the nut on the hub to work loose, then also there is backlash. But if you have hum still necessary to replace the hub bearing VAZ-2109.

Training for repair

Prepare the car for repair. To do this, be sure to install wheel chocks. You will also need at least one prop. Desirable, of course, special counter, but since its cost is high, not everyone can afford such a luxury. So you can use the cheaper option – a few wooden bars. If you are replacing the rear wheel bearings, the struts are placed under the front wheels, and Vice versa.

Next, you will need a tool. To carry out the entire job as quickly as possible, you need to have not so much skills as keys and pullers. Without them in this matter just can not do. Remove the cap from the wheel, which will undergo renovations. As a rule, there is grease, so the nut will break relatively easily. Now should talk about the tool that you will need for a replacement.

What is a necessary tool

Most importantly – this is a special bearing puller. It is possible to make of bolt, nut, thick washer and the metal Cup (not that, of course, from which tea is drunk). But easier would be to buy a puller, since it is relatively inexpensive. Besides it not only repair of the front bearing. When done replacing the rear wheel bearing, it will come to the rescue. Just a universal thing, so will buy, will not regret!

Another important tool – key 30. Unfortunately, in the stores they are extremely rare. Will either have to seek it from friends, or tinkering on their own. However, the latter is simple enough, only need a head 30 and a metal rod, which you need to bend the letter G, and the edge grind so that he had a square section. After that, the edge of this set in the head and boil thoroughly. The only way you will be able to achieve maximum rigidity. To this key, it is desirable to have a section of pipe that will act as a lever – hub nut very difficult to Unscrew. The reason for that – the big moment when the fastener is tightened.

Removing a bearing

To remove the hub, you will have to do some manipulation. Replacement bearing front hubs of VAZ-2109 is performed quite quickly, within an hour you can make the repairs one side. First Unscrew the nut. For this you need to raskontrit using a drift and hammer. Then, by means of a key 30, to twist. Only after these manipulations it is possible to raise the car and remove the wheel. Now you need to Unscrew the nuts on the bolts that secure the hub to the rack. After twisting the two bolts with the ball joint. It only remains to pull the hub Assembly towards yourself to remove it from the splines of the drive.

Now, the big moment - the replacement bearing front hubs of VAZ-2109. Talked about the “white” and “black” methods of extraction of the hinge. The last – a method in which the hub is mounted on the right size support, and then just knocked bearing a large hammer. No easy task, takes a very long time. Yes and damage the hub without problems. For this purpose it is better to use a puller, with it bearing much faster out of the seats.

Installing the new bearing

Install the new bearing can be performed in two ways. If you have a puller, you do not need to look for some difficult ways, you fitting with it. This is the best option. But if not, then what to do? Immediately comes to mind is basic physics, namely – the expansion and contraction ofmetal. Replacement bearing front hub vases can pass relatively quickly, if you adopt a few laws of physics.

You Have in your hands the two elements – the bearing and hub. The latter can be expanded, first to narrow. You enough hundredths of a millimeter difference, to easily carry out the installation. This bearing is placed in the cold. If it happens in winter, in the bitter cold, the case is simplified. In the summer you can throw it in the freezer. Now pay attention to the fact that the bearing is protected, it is made of rubber, which at high temperature to melt. So warm up the hub a long time is not necessary. 60-70 degrees is quite enough, so the bearing is easy came to your place.

Assembly hub

That's all, now you only have to cool the hub and to engage in it. It should be noted that the camber will be broken. So before you remove the hub mark its position relative to the rack. Accuracy, of course, not jewelry, but wear of the tires will save. When completed the replacement bearing front hubs of VAZ-2109, start to install all elements in reverse order. Install the hub into the rack and fix the position of the bolts.

Then attach to the lower arm housing of the ball joint. Incidentally, the repair of the wheel bearing there is no need to vypressovyvaniem ball, it is sufficient to Unscrew the bolts. Therefore, a special puller at work is not needed. After hub took his position, do the alignment, it marks you made before disassembly. Only after that tighten the two nuts on the rack. Please note that the top has eccentric washers, they adjusted the front camber.

Replacing the rear bearing

On the rear hubs to replace even easier, because you do not need to remove ball joint. Two bolts less. But if the braking system is modified, installed drives, you'll have to completely disassemble the calipers. Only after that will remove the hub. The rest of the replacement of the rear bearings is the same as described above. Same strippers, same key, everything is done by analogy.

Conclusion

In conclusion, I would like to note that the service life of the bearings depends on the quality of the product. Grease they pressed on from the factory, to check its presence alone is not possible. Of course, alternatively, you can remove the protective seal, but then damage the bearing. But in this case you can fill the grease. To facilitate rotation of the bearings, between them the entire axle shaft liberally. But it is better when being replaced the front bearing, not to touch anything. Just buy the parts as a reliable manufacturer and hope that it's not a fake (which, incidentally, are very easy to identify by their appearance).
