Grenade (or CV joint - constant velocity joint) on Škoda Fabia 1 first generation (1999–2007) - one of the most vulnerable parts of the chassis. Wear of this unit is manifested by a characteristic crunch when turning, vibration at speed, and even wheel wedging. If you ignore the problem, the consequences may come back destruction of the axle shaft, damage to the wheel bearing or an accident on the highway.

Signs of a CV joint failure on a Škoda Fabia 1
The first symptom of grenade wear is crunch when turning, especially at full turn of the steering wheel. On Fabia 1 this is more pronounced at speeds of 15–30 km/h. However, the crunching noise can also come from the wheel bearing, so it is important to differentiate the problems:
- 🔊 CV joint crunches only when turning (left or right) and load (acceleration).
- 🌀 The bearing is humming constantly, regardless of steering angle, and the noise increases with speed.
- 🚗 Vibration on the steering wheel when accelerating - a sign of wear internal CV joint (requires urgent replacement!).
On Fabia 1 with mileage >150 thousand km often fails grenade boot - its rupture leads to dirt and sand getting into the hinge, accelerating wear. If cracks or traces of grease are visible on the boot, the CV joint is already damaged, even if there is no crunching noise yet.
⚠️ Attention: On Fabia 1 with engine 1.9 TDI CV joint wear appears earlier due to high torque. You can check the condition of the grenade by rocking the drive shaft manually - play >1 mm indicates the need for replacement.

Which CV joints to install on the Škoda Fabia 1: original vs analogues
Original CV joints from VW Group for Fabia 1 are indicated by articles:
- 🔧 Outer CV joint:
6Q0 498 081(left) /6Q0 498 082(right) - 🔧 Inner CV joint:
6Q0 498 077(for both sides) - 🔧 Outer CV joint boot:
6Q0 498 115
The cost of the original is from 8,000 to 12,000 rubles per set (internal + external). However, many owners Fabia 1 choose analogues from trusted brands:
| Brand | Article (outer) | Article number (internal) | Price, rubles (set) | Features |
|---|---|---|---|---|
| GKN (Loebro) | KD 3000 |
KD 3001 |
5 500–7 000 | High quality, often included with anthers |
| SKF | VKJA 6633 |
VKJA 6634 |
6 000–8 000 | Reinforced bearings, suitable for 1.9 TDI |
| Febi | 23500 |
23501 |
4 500–6 000 | Budget option, but the resource is lower than the original |
When choosing an analogue, pay attention to quality of anthers — cheap rubber products crack after 20–30 thousand km. The best option is polyurethane boots (for example, from CTR or Hutchinson).
Before buying a CV joint, check it for the presence of lubricant - there should be a bag of it in the box molybdenum grease (for example, Molykote BR2 Plus). Without it, the grenade's lifespan is reduced by 2–3 times.
Tools for replacing CV joint on Fabia 1
To work you will need:
- 🔧 CV joint puller (for example, KUKKO 204-2 or equivalent)
- 🔧 Socket heads at 13, 16, 17, 19 mm and knob
- 🔧 Torque wrench (for tightening the hub nut with a torque of 220–250 Nm)
- 🔧 Hammer and pry bar (for dismantling the drive)
- 🔧 WD-40 or liquid key (sticky bolts are a common problem on Fabia 1)
If you plan to change internal CV joint, you will also need:
- 🔧 Retaining ring (article
N 908 132 02) - 🔧 Grease for CV joints (200–300 g)
- 🔧 Boot clamps (it's better to take screw, not spring ones)
⚠️ Attention: On Fabia 1 with ABS the drive cannot be damaged when dismantling pulse ring on the hub. If the ring is bent, the ABS sensor will generate an error.
Step-by-step replacement of the outer CV joint on a Škoda Fabia 1
The process of replacing an external grenade takes 2–3 hours. The main thing is to take your time and follow the algorithm:
- Removing the wheel and caliper.
Jack up the car, remove the wheel and unscrew the caliper (13 mm bolts). Hang the caliper on a wire to avoid damaging the brake hose.
- Removing the hub nut.
Unscrew the drive nut (size
30 mm) using a head and a lever. If the nut is stuck, use WD-40 and an impact wrench. - Removing the ball joint.
Unscrew the ball bolt (16 mm) and press the pin out of the lever with a pry bar. Be careful - your finger may shoot out!
- Removing the drive.
Pull the hub towards you and the drive will come out of the box. If it doesn't work, gently tap the wooden spacer with a hammer.
Next - replacing the CV joint itself:
- Removing an old grenade.
Clamp the drive in a vice, remove the boot clamps and cut it off. Then use a puller or hammer to knock down the retaining ring and remove the CV joint.
- Installation of a new CV joint.
Apply lubricant to the splines, put on a new boot, install the CV joint and secure with a retaining ring. Tighten the clamps.
- Assembly.
Insert the drive back into the box (hear a click), secure the ball, put on the caliper and tighten the hub nut to a torque
220–250 Nm.
☑️ Checklist before assembly
Replacing the inner CV joint: nuances for Fabia 1
Inner CV joint on Fabia 1 changes less frequently, but the process is more complicated - the axle shaft must be completely dismantled. Main stages:
- Removing the drive from the box.
After dismantling the outer CV joint, pull the shaft out of the gearbox. Be careful - if the drive “bites”, do not pull it! Water the joint WD-40 and wait 10–15 minutes.
- Replacing the internal grenade.
Remove the retaining ring and tap the CV joint with a hammer through the mandrel. The new hinge is installed similarly to the outer one, but with mandatory checking axial play (should be < 0.5 mm).
Important point: on Fabia 1 with manual transmission when installing the drive back into the box, you need to align splines on shaft and differential. If the drive does not fit in, turn it 180°.
What to do if the drive does not come out of the gearbox?
If the shaft is “jammed” in the box, do not use force! Remove the transmission pan, find the place where the drive is attached to the differential and carefully knock it out with a wooden mallet through the copper spacer. The cause is usually corrosion or deformation of the splines.
Typical mistakes when replacing a CV joint on a Fabia 1
Even experienced craftsmen make mistakes that lead to repeated repairs. Here are the most common:
- 🔧 Insufficient lubrication. Without molybdenum lubricant, the CV joint will last no more than 20 thousand km.
- 🔧 Poorly tightened hub nut. It will lead to wheel play and steering wheel wobble.
- 🔧 Damaged boot. The slightest crack and the grenade will die in 5-10 thousand km.
- 🔧 Misaligned splines. If the drive is not fully inserted into the gearbox, it may jump out at speed!
Another common problem is re-tightening of boot clamps. If they are tightened too much, the rubber will crack. Optimal force - the clamp should tightly press the boot, but not cut into it.
After replacing the CV joint, be sure to check wheel angle (wheel alignment). Even a small drive misalignment can disrupt the suspension geometry.
Cost of replacing a CV joint: service vs self-repair
Prices for replacing CV joints Škoda Fabia 1 in services in Moscow and regions (for 2026):
| Type of work | Cost, rubles (service) | Cost, rubles (on your own) |
|---|---|---|
| Replacement of outer CV joint (1 side) | 3 500–5 000 | 1,500–2,500 (spare parts) |
| Replacing the inner CV joint (1 side) | 5 000–7 000 | 2,000–3,500 (spare parts) |
| Replacing the boot (without removing the CV joint) | 2 000–3 000 | 500–1 000 |
The savings when doing your own repairs are obvious, but keep in mind risks:
- 💥 Damage ABS in case of careless dismantling.
- 🔧 Incorrect tightening of the hub nut (will lead to play or bearing play).
- 🛑 Errors during assembly, due to which the CV joint will fail after 5–10 thousand km.
If you are not confident in your abilities, it is better to entrust the work to a proven service. This is especially true for replacement internal CV joint — experience with checkpoints is required here.
Frequently asked questions (FAQ)
Is it possible to drive with a crisp CV joint?
Short-term (1-2 weeks) - yes, but not worth the risk. The destruction of the CV joint at speed can block the wheel, which will lead to skid or accident. At the first sign of a crunching sound, check the boot and lubrication level.
Which CV joint fails more often on Fabia 1 - internal or external?
On Fabia 1 breaks down in 80% of cases outer CV joint (due to large rotation angles). The internal one lasts longer, but its replacement is more difficult - complete dismantling of the drive is required.
Is it necessary to change the gearbox oil after replacing the CV joint?
If the drive was pulled out of the box, some of the oil could leak out. You can check the level via inspection hole (on Fabia 1 it is located on the right at the checkpoint). Top up if necessary VW G 052 726 A2 (or equivalent).
Is it possible to restore a CV joint without replacing it?
Theoretically, yes, if the wear is not critical. To do this you need:
- Remove the CV joint and wash it in kerosene.
- Replace the lubricant with molybdenum.
- Install a new boot.
But such repairs are a temporary solution (will last 10–20 thousand km). With heavy wear clips or balls The CV joint can only be replaced.
How to check the CV joint on a Fabia 1 without a puller?
The simplest test:
- Hang the front wheel (on the side where you suspect a fault).
- Start the engine, engage 1st gear.
- Step on the brakes and give the gas. If the crunching intensifies, the CV joint is faulty.
Also check the shaft play by hand - if it “hangs” in the boot, it’s time to change the grenade.
