Introduction: why does Grant need CV joints and where are they hiding?
The question “how many CV joints are there in Lade Granta"seems simple only at first glance. In practice, the answer depends on the modification of the car, the type of drive and even the year of manufacture. Constant velocity joints (CV joints) are critical transmission elements responsible for transmitting torque to the wheels during cornering and vertical suspension movements. Their malfunction is manifested by a characteristic crunching sound, vibrations and can lead to complete immobilization of the machine.
In this article we will look at exact diagrams of the location of CV joints for all versions of Granta (including Granta FL, Granta Sport and Cross), we will explain why their number varies from 2 to 6, and give practical advice on diagnosis. We will pay special attention to the “pitfalls”: for example, why some Grants may not have a rear CV joint, despite the presence of a drive to the rear axle.
Drive design Grants: front-wheel drive version (2190/2191)
Most Lad Grant come off the assembly line in a front-wheel drive configuration - these are basic sedans and liftbacks with indexes 2190 and 2191. Here the arrangement of CV joints is as simple as possible:
- 🔧 Two outer CV joints - one for each front wheel. They connect the hub to the drive shaft and take on the main load when cornering.
- 🔧 Two inner CV joints - located on the gearbox side. Their task is to compensate for the movements of the engine and gearbox relative to the suspension.
Thus, in the standard front-wheel drive Grant only 4 CV joints. However, there is a nuance here: on cars with robotic gearbox (AMT) internal hinges may have a reinforced design due to increased loads during switching. Their service life is 15–20% higher than that of versions with “mechanics”.
It is important to understand that external and internal CV joints differ not only in location, but also in design. External ones (from the wheel side) are usually ball joints with a six-ball circuit, while the internal ones are tripoid, with rollers on three arms. This is due to different working angles and loads.
Granta with rear wheel drive: myths and reality
Among the owners Lada Grants There is a persistent misconception about the existence of an “all-wheel drive” version of this car. Actually a factory AvtoVAZ I never produced a Grant with a plug-in rear axle or permanent all-wheel drive. However, there are two modifications where the rear axle is equipped with CV joints:
- Lada Granta Sport (VAZ-219000) - a sports version with rear-wheel drive, released in a limited series in 2013–2015. Here the rear axle is driven through cardan shaft, and CV joints are installed only on the rear wheels (2 pieces - internal and external for each wheel).
- Granta Cross (after 2020) — a cross-version with increased ground clearance, but remains front-wheel drive. There are no rear CV joints here.
Thus, only Granta Sport can boast 6 CV joints (4 front + 2 back). All other modifications, including Granta Drive Active, remain front-wheel drive with classic 4-joint joints.
Why doesn't the Grant have all-wheel drive?
Initially platform Lada Grants was developed as a budget front-wheel drive car. Adding all-wheel drive would require major modifications to the body, suspension and transmission, which would increase the cost of the car by 20-30%. AvtoVAZ made a bet on Lada Vesta SW Cross and Niva Travel like crossovers with all-wheel drive.
Table: number of CV joints by Grant modifications
| Modification | Drive type | Number of CV joints | Features |
|---|---|---|---|
| Granta Standard/Norma/Lux (2190/2191) | Front | 4 | 2 external + 2 internal. The AMT has reinforced internal CV joints. |
| Granta FL (restyling) | Front | 4 | No changes to the transmission. CV joints with extended life are possible (from 2019). |
| Granta Sport (219000) | Rear | 6 | 4 in the front (even though the drive is rear-wheel drive, the front axle is kept for safety) + 2 in the rear. |
| Granta Cross | Front | 4 | Increased ground clearance, but the drive remains front-wheel drive. CV joints with reinforced boots. |
Please note: on Granta Sport the front axle retains CV joints even with rear-wheel drive. This is done to ensure directional stability and safety in the event of rear transmission failure. However, these hinges do not transmit torque - they act as “idle” connectors.
How to determine a CV joint malfunction: symptoms and diagnosis
The average lifespan of CV joints on Grant is 80–120 thousand km, but can be reduced to 50 thousand km with aggressive driving or damage to the anthers. You can recognize wear on the hinges by the following signs:
- 🔊 Crunch when turning - especially noticeable when fully loaded or with the steering wheel turned out. The outer CV joint crunches when turning left/right, internal - when driving over uneven surfaces.
- 🌀 Vibration at speeds of 60–80 km/h - often confused with wheel imbalance. Difference: vibration from the CV joint increases during acceleration.
- 💨 Grease leaks on boots - if the boot is torn, the CV joint fails within 500–1000 km.
For an accurate diagnosis, follow these steps:
Suspend the front axle on a lift or jacks
Spin the wheels manually - listen for a crunch
Check the shaft play (rock the shaft along the axis by hand)
Inspect the anthers for cracks and grease -->
⚠️ Attention: Do not confuse the crunch of a CV joint with the sound of worn wheel bearings. The bearing makes noise all the time, and the CV joint only makes noise when turning under load. To make sure, just drive in a straight line with the steering wheel turned: if the crunch disappears, the CV joint is to blame.
If you find a fault, do not delay replacement. A worn CV joint may jam while driving, which will lead to loss of control. This is especially dangerous at speeds above 60 km/h, when the shaft can simply break.
Replacing a CV joint on a Grant: what you need to know before repair
Independent replacement of the CV joint with Lade Granta possible, but requires preparation. Here are the key points:
- Tool: you will need heads for
17,19,30, circlip puller, hammer and pry bar. For the inner CV joint it may be necessaryhexagon 6for unscrewing the tripoid bearing. - Lubrication: use only specialized lubricant for CV joints (for example, LIQUI MOLY LM47 or CV joint-4). Regular Litol-24 not suitable - it cannot withstand high temperatures.
- Anthers: always replace them together with the CV joint, even if they look intact. The cost of the boot is only 200–300 rubles, and its rupture will result in repeated repairs.
Average cost of work to replace a CV joint in a service:
- 🔧 External CV joint: 1500–2500 rub. (for one side).
- 🔧 Internal CV joint: 2000–3500 rub. (requires removal of the axle shaft).
- 🔧 Set (shaft + 2 CV joints + boots): 4000–6000 rub. per side.
Before installing a new CV joint, be sure to check the condition gearbox oil seal from the drive shaft side. If it leaks, the oil will quickly wash the lubricant out of the joint and it will fail.
If you decide to change CV joints yourself, follow the rule: always replace with a pair (left and right). Even if one joint looks good, its wear has already begun, and after 10–15 thousand km you will have to disassemble the suspension again.
Frequent mistakes when replacing CV joints on Grant
Even experienced car owners make mistakes that shorten the service life of new CV joints. Here are the most common:
- ❌ Retightening the hub nut - the tightening torque should be
225–245 Nm. Exceeding this leads to destruction of the wheel bearing. - ❌ Using non-original anthers - cheap rubber boots harden in the cold and crack within a year.
- ❌ Incorrect installation of the retaining ring - if the ring is not fixed, the shaft may jump out of the box while moving.
- ❌ Lack of lubrication on the shaft splines - this leads to corrosion and “sticking” of the shaft to the hub.
⚠️ Attention: When replacing the inner CV joint on a Grant with robot AMT be sure to reset the gearbox adaptations via a diagnostic scanner (for example, Launch X431). Otherwise, the robot will “twitch” when switching for the first 100–200 km.
Another typical problem is dirt getting into the box when replacing the inner CV joint. To avoid this, before removing the shaft, seal the hole in the gearbox with tape or a special plug. It is also not recommended to use WD-40 to clean the splines - it washes away the factory lubricant.
FAQ: answers to popular questions about CV joints Grants
Is it possible to drive with a crisp CV joint?
Short-term - yes, but no more than 1-2 weeks. A crunch indicates critical wear of the balls or rollers. If you ignore the problem, the CV joint may fall apart while driving, leading to loss of control and damage to the axle shaft. It is especially dangerous to drive with a faulty internal CV joint — its fragments can get into the gearbox.
Which CV joint fails more often: internal or external?
On Lade Granta outer CV joints break down 3 times more often than internal ones. This is due to higher operating angles (up to 45° with the steering wheel turned) and loads. Inner CV joints usually last longer, but they are more difficult to replace and require removal of the axle shaft.
Is it possible to restore a CV joint without replacing it?
Theoretically yes - some workshops offer CV joint bulkhead with replacement of balls and separator. However, in practice this is unprofitable: the cost of the work is comparable to the price of a new CV joint (RUB 1,500–2,500), and the service life of a restored joint rarely exceeds 30 thousand km. The exception is collector or sports cars where original CV joints are not available.
Which CV joints are better to install on Grant: original or analogues?
Original CV joints AvtoVAZ (article 2108-2215010 for outdoor and 2108-2215030 for internal) are optimal in terms of price/quality ratio. Among the analogues, the following have proven themselves well:
- GKN (Loebro) - the resource is 20–30% higher than the original, but the price is 1.5–2 times higher.
- SKF - reliable, but require mandatory verification when purchasing (there are many fakes).
- Pilenga - a budget option, suitable for temporary replacement.
Avoid cheap Chinese CV joints without a brand - their service life rarely exceeds 20 thousand km.
Do I need to balance the drive shaft after replacing the CV joint?
On Lade Granta Shaft balancing is not required if you use quality parts and do not damage the factory markings. An exception is cases when the shaft was deformed (for example, after an accident). Signs of imbalance: vibration at speeds of 90–110 km/h, which disappears when the engine brakes.
On a Grant with an AMT robot, the internal CV joints wear out 15–20% faster due to jerks during shifting. Check the boots regularly - this will extend the life of the transmission.
