Replacing cardan shafts in the field
Welcome! The driveshaft is a very important part for both all-wheel drive and rear-wheel drive cars, the car will not drive without it, thanks to this shaft, which looks like a large metal stick, torque is transmitted from the gearbox to the gearbox , well, the gearbox now starts up on the wheels themselves and thus the car moves.
Note! To replace this part on a Niva car, you will need to stock up on the following tools, namely: A set of wrenches (Exactly wrenches, others will not work), we also recommend taking a healthy screwdriver (Or a medium-sized one if you don’t have a larger one)!
Summary:
Where are both driveshafts located? As you already understood from the title of the article and from the inscription just above, there are only two cardan shafts in the Niva car, for example, if we talk about the rear-wheel drive Classic, then there is only one cardan on it, and it’s very difficult to remove them on both the Niva and the Classic easily and almost identically, that is, the nuts securing the driveshaft flanges were unscrewed and the shafts were removed from the car (we’ll talk about how to unscrew these nuts a little later), you can see more details about where these driveshafts are located in the article entitled : “Replacing cardan drive crosspieces on a VAZ”, there will be a picture in which these shafts are indicated with a red arrow, in addition, read the article linked above, since these crosspieces fail from time to time and so that you generally know what the symptoms are will be reflected on the car, read the article to which the link is given, everything is written in it.
When do you need to change driveshafts? It’s practically never necessary, unless of course you operate the car normally in urban conditions and don’t drive it in the mountains, the whole point is that the cardan shafts themselves almost never fail or fail, it may happen that you touch them and in connection why do they bend, then after that you need to change them immediately, if you don’t do this and drive on bent shafts, then firstly the power will drop and it will rotate unevenly, and therefore the crosspieces will wear out very quickly, they will start knocking and A number of other problems are yet to arise.
Servicing the driveshaft spline
We lubricate the spline joint of the sliding yoke of the propeller shaft by pumping grease with a syringe through a grease nipple until the grease comes out from under the seal.
Using a syringe with a narrow tip, lubricate the universal joint bearings through a grease nipple until the grease comes out from under all the seals
If there is no narrow tip for the syringe, then you will have to remove the cardan shaft and syringe on the removed cardan.
Rear driveshaft of the Niva Chevrolet car: features, tasks and replacement
Being a car from the jeep class, the Chevrolet Niva is, accordingly, equipped with all-wheel drive. But how else than a cardan transmission can transmit torque from the transfer case to the wheels. Now let’s look at the full picture of the rear cardan of the Niva Chevrolet car, its features, structure, how the replacement is carried out if faulty breakdowns occur.
How to replace driveshafts on a VAZ 21213-VAZ 2131?
Removing it: As we have already said, there is nothing complicated in its removal, just take a screwdriver and if you have an assistant with you, then generally good, first ask him to hold the shaft so that it does not fall when you disconnect one of the sides (And without an assistant this work can be done, it just won’t be convenient), as soon as he holds one of the sides with his hands, take a screwdriver in your hands and insert it between the bolt and the cardan fork as shown in photo 2, thereby you will ensure that the bolt will no longer turn , as soon as the operation is done, unscrew the nut of this bolt that you hold with a screwdriver (see photo 1) and then remove this bolt from the hole, do exactly the same operation with the other bolts and remove them all, thereby, as soon as the bolts are removed, on the one hand, the cardan will no longer be attached to anything and will simply be in the air (the part that hangs in the air, we recommend that an assistant hold it), and then on the other hand (the cardan will be attached in both directions, in absolutely identical ways to that same) unscrew all the bolts in the same way and thereby remove the driveshaft from the car (For example, photo 3 shows the removal of the rear driveshaft, you may be removing the front driveshaft; this is already photo 4, but that’s not the point, they are removed identically), and the second driveshaft as You already understood, remove it in exactly the same way, unscrewing all the nuts of the bolts that secure the cardan on both sides.
Note! If the driveshaft rotates when you unscrew the nuts, then ask an assistant to hold it with your hand, or the best way is to insert a thick screwdriver into the very place shown in photo 2 and thereby you will ensure that the bolt does not move (so that the nut it is normal to unscrew it) and fix the cardan shaft itself in this way so that it does not rotate!
Lada 4×4 5D Chupacabra › Logbook › A semi-sad story - replacing the front driveshaft with a CV joint.
After replacing the rear universal joint with a CV joint, I decided to replace the front one as well.
I bought this shaft on Niva-Lada4x4 (sold without nuts - I already screwed it on): Yesterday I went to unscrew the old driveshaft, worked without a hole, having unscrewed 3 bolts on each side, I wanted to jack up the wheel to spin the cardan, but when I got up I heard a crunch in my knee and the leg is stuck in one position - approximately 90 degrees
