The topic of the article is what you need to know about replacing the CV joints of the VAZ 2109, what subtlety there is in this matter. In fact, there is nothing complicated, you do not even need to drive a car into a pit, everything can be done by putting it on reliable supports. It is best to repair first on one side, then on the other. So it will be much more effective, and do not have to think about what to insert instead of the hinge in the box. After all, you know that with the simultaneous extraction of both CV joints, the differential is destroyed.
Tools for work
To carry out all work on the replacement of CV joints VAZ 2109, it is necessary to have at your disposal a certain tool. That's about it, and it's worth a talk. Firstly, it is desirable to have metal supports that need to be installed under the side of the car on which repairs are carried out. Secondly, it is necessary to have stops that will not allow the machine to roll down. Thirdly, a reliable jack is needed. Fourth, you need some special tools.
The most important one is a good key for 30. It is desirable to have a face, with a strong handle. With it, a hub nut is twisted, which is tightened with a large torque. Also, you can not do without the pull rod puller. In some cases, you may need a puller ball. But it is needed when the balls have become worthless. Of course, a vice, a hammer, a chisel and a set of keys. However, you can begin to prepare for repair.
Preparation for repair
First lift the car. But before this, fix its position with anti-skid stops and tear off the nut on the hub. For this, unscramble it and, having installed the key with a large lever, try to unscrew it. Note that on both sides the thread on the hubs is different. After you rip off the nut, you can lift the side of the machine and remove the wheel.
But now the question is, when replacing the CV joints of the VAZ 2109, does it need to drain the oil from the box? The answer is unequivocal - it is necessary! But you can not all merge, but only two-thirds of the total. The fact is that the oil will start to flow when you remove the drive. And if you do not plan to replace it, then do not risk and lose expensive oil. After this it is necessary to remove the steering tip. To do this, unscrew the nut, pre-extract the cotter pin. Using a puller, press out your finger from the pivot of the rack. Also, it is necessary to unscrew the two bolts that secures the ball bearing housing to the hub.
Removing drive
Now you can remove the drive. Even replacement of the anther of the outer CV joint VAZ 2109 is better and faster when the drive is completely removed. But not only in this trick. The fact is that when replacing anther, it is worthwhile to flush the hinge and to hammer into it a new lubricant. So you can increase its service life, unless, of course, you will not "kill" the drives with aggressive driving style. Unscrew the nut completely from the hub. Now you can carefully extract the external CV joint from it.
For this, carefully, trying not to damage the brake tube, pull the rack, holding the disc. The hub must be easily removed from the splines on the drive. That's all, now you need to extract the inner one. Take into account the fact that you have already drained the oil from the box. Therefore, using a small chisel, which you put between the box and the hinge, as well as the hammer, knock out the CV joint from the gearbox. Do not try to lay a crowbar, in this case only a weak but sharp blow will save.
What parts are needed for replacement
Of course, a set of CV joints. What kind of production to choose - decide for yourself, but most importantly - to have all the necessary elements: yokes, grease, hinges, locking rings. If there are no them in the complete set buy separately, they cost not so much. Also, sometimes it is necessary to replace the oil seals CVDs VAZ 2109. But only if you observed oil leaks in the box area. Although, if you look at their life, it is better to replace when removing the drive. So it will be much more effective.
In addition, it is possible that you will find faults in some of the suspension and drive components. For example, excessive bearing wear of the hub. In this case, it is recommended to replace it. It is also possible that you will find a broken ball bearing. And it must be disconnected to remove the drive. Turn your finger ball to see if it has any jam. If its movement occurs with jamming, then you need to change the ball, otherwise it will very soon start crackling.
Replacement of internal CV joints
When you remove the drive, you can begin to replace the hinges. If only the replacement of the anther of the internal CV joints of the VAZ 2109 is planned, then it is necessary to shoot off the semi-axle only the outer hinge. But flushing the inside and chocking in it of a new lubricant is highly desirable. To completely replace the internal CV joints, it must be knocked off the semi-axle. Since you no longer need a hinge, you should not regret it, you can act in the most barbarous ways.
Hold firmly in one hand the drive, into the second hammer. And apply sharp and strong blows on the inner SHRUS. In order not to hold the drive in your hand, it can be clamped in the vice. So it will be much easier to work. After that, wipe the splines on the drive, remove the old ring and put in its place a new one. But before that install anther. Then gently stuff the new hinge. Under the dust cover, squeeze out all the lubricant from the tube that comes with the kit. Put a part directly on the hinge. Put on an anther and fix it with clamps.
Replacement of external CV joints
If it is planned only to replace the anther of the outer CV joints of the VAZ 2109, then at the last stage it is just necessary to pull it and cut the old one. But if you need to replace the entire hinge, then follow the same pattern as in the last paragraph. Clamp the drive tightly in a vise and a hammer knock down the CV joint from it. Do not feel sorry for him, because the new one will last you for many years, if the driving style is not very aggressive.
As in the previous paragraph, first thoroughly clean the semiaxis, wipe it dry, and then mount all the elements. First the anther, then the ring, stuff the CV joint on the splines. That's all, it remains only to squeeze out all the lubricant under the duster and put it on, tightening the clamps. Pay attention to the fact that the clamp type worms can not be used, they will rest against the hub.
Installing the drive
And in the end, the entire drive is installed and the entire side of the suspension is assembled. First put the inner SHRUS. You fall on the splines, then apply a couple of sharp strokes on the drive. This will allow the ring to slip inside, having previously contracted to the minimum diameter. Please note that the grenade should fit snugly against the box, this is its normal position. But do not forget that the SHRUS is slightly shifted along the axis of the wheels.
Next, what you need to know about replacing the CV joints of the VAZ 2109 is the mounting of the outer hinge. To do this, install it against the hole in the hub and, gently pushing the latter, gently enter it. To make sure finally that the pomegranate has come to the end, you can hit a couple of sharp hits on the hub. Just substitute the wooden bar for softening. In the future, the hub will fully fit when you tighten the nut. That's all, now you can collect the side and proceed with the second.
Conclusion
After replacing all the hinges, do not forget to fill the box with oil. If you try to move from the spot, you hear that the box is spinning, but the movement to the wheels is not transmitted, then the diagnosis is unambiguous - some internal CV joint has not come to its place, not hit the slots. We'll have to find out what's up, and re-install it, following all the recommendations. It is also worth noting that the replacement of the CV joint without removing the drive VAZ 2109 can be carried out, but it will be much more difficult to perform. Spend a lot of time and effort.
