The duster torn. CV joint (constant velocity joint) on Škoda Rapid It is a problem that cannot be ignored. Even a small crack leads to dirt and moisture in the mechanism, which accelerates wear and tear. grenades 5-10 times. As a result, after 1-2 thousand kilometers, you will have to change not only the anther, but also the ShRUS itself, and this is already 3-4 times more expensive. In this article, we will discuss how self-replace on Rapid (including restyled models of 2017+), without referring to the service station.
The procedure does not require special skills, but will pull mandatory reinstallation of locking rings and check of backlash of SRUS - it's critical for safety. We will describe each stage in detail: from fault diagnosis to final assembly, as well as give tips on the choice of spare parts (original vs analogues) and tools. If you’ve never worked with the chassis, start by watching video instructions – this will help visualize the process.
Signs of damage to the CV joint boot on a Škoda Rapid
The first sign of a problem is characteristic crunch When turning wheels (especially at full load). But in the early stages of an anther damage, there may be no sound. Pay attention to these indirect signs:
- 🔍 Traces of grease on the inside of the wheel or under the wing. These are usually dark spots that are difficult to clean.
- 💨 Clicks When moving from a place or a sharp acceleration. The sound comes from the damaged anther.
- 🛑 Vibration on the steering wheel at a speed of 60-80 km / h, which disappears after acceleration.
- 🔧 Backlash in the drive, checked by swaying the wheel in suspension.
On Škoda Rapid suffers more often external CV joint (from the wheel side), since it experiences heavy loads when turning. The internal one (from the gearbox side) fails less often, but its diagnosis is more difficult - removal of the axle shaft is required. If you ignore the cracks in the boot, the grenade may fall apart on the fly, which will lead to loss of control.
⚠️ Attention! If after washing or rain the crunching intensifies, this is a sure sign of water getting into the CV joint. In this case The boot must be replaced immediately, even if visually no cracks are visible.
- Every 10,000 km
- Only when a crunch appears
- Never checked
- Only for maintenance
What tools and spare parts will be needed
To replace the boot with Rapid you don't need expensive tools, but there are a few mandatory positions, which you can’t do without:
| Tool/spare part | Purpose | Notes |
|---|---|---|
| Socket set (17, 19, 30 mm) | Unscrewing the hub nut and CV joint bolts | The 30mm head should be percussion |
| Torque wrench | Tightening the hub nut with a torque of 200–220 Nm | Without it there is a risk of over tightening or under tightening |
| Circlip remover | Removing/installing rings on the CV joint | Can be replaced with thin pliers |
| Hammer and wooden spacer | Knocking out the CV joint from the hub | Spacer protects threads |
| Grease for CV joints (100–150 g) | Filling the boot after installation | We recommend LIQUI MOLY LM47 or Castrol Optitemp |
For spare parts: original boot Škoda has an article number 1J0 498 105 (external) and 1J0 498 106 (internal). Cost - from 1,200 to 1,800 rubles. Alternatives:
- 🔧 Febi (article 14520) - high-quality analogue, price ~800 rub.
- 🔧 SKF (VKJA 6630) - premium segment, price ~1,500 rub.
- 🔧 Trialli (GJF 001) is a budget option, but the risk of defects is higher.
Don't skimp on clamps! Original plastic clamps Škoda (article N 908 132 02) more reliable than metal analogues. Also purchase new hub nut (article N 905 477 02) - its reuse is prohibited!
Before purchasing a boot, check its diameter against the old part. On Rapid with 1.4 TSI and 1.6 MPI engines, the dimensions of the internal CV joint may differ.
Step-by-step instructions for replacing the boot
The replacement process will take 3-5 hours depending on experience. Carry out work on flat ground with reliable wheel supports. If there is no inspection hole, use a jack with stands.

Step 1: Removing the Axle Shaft
Loosen the hub nut (tightening torque 200 Nm) while the machine is on its wheels. Then lift the car, remove the wheel and unscrew the nut completely. Next:
- Disconnect tie rod end (unlock the nut, use a puller).
- Unscrew the fastening bolts ball joint to the steering knuckle.
- Remove the brake caliper (hang it on a wire, do not disconnect the hose!).
- Drive the CV joint out of the hub with a hammer through a wooden spacer.
Step 2: Disassembling the CV joint and replacing the boot
After removing the axle shaft, clamp it in a vice (through soft pads). Next:
- Remove retaining ring from the shaft (use a puller or thin pliers).
- Carefully slide the boot along the shaft and clean it of old grease.
- Check separator and balls CV joint for wear (play more than 0.5 mm is a sign of replacing the grenade).
- Install a new boot, first applying lubricant to the shaft and CV joint.
Step 3: Assembly and Testing
After installing the boot:
- Secure it with clamps (original clamps Škoda tightened with special pliers).
- Place the axle shaft back into the hub and tighten the hub nut with a torque wrench.
- Reassemble all components in reverse order.
- Check for play by shaking the wheel in a suspended position.
What to do if the CV joint does not come out of the hub?
If the grenade is stuck, use a puller or WD-40. As a last resort, gently heat the hub with a hair dryer (no higher than 100°C) so that the metal expands. Do not hit the CV joint directly with a hammer - this will damage the threads!
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing the boot. Here are the most common:
- 🔧 Reusing the hub nut - this disrupts the tightening torque and can lead to the nut unscrewing while moving.
- 🔧 Insufficient lubrication CV joint - without it, the grenade will last no more than 5,000 km.
- 🔧 Re-stretching clamps - this cuts the boot from the inside, especially if the clamps are metal.
- 🔧 Ignoring circlips - without them, the CV joint can jump off the shaft.
Another critical error - incorrect installation of the boot. He must sit tight, without distortions, and the corrugations should be directed in the direction of movement (this prevents “sucking in” dirt). After assembly, be sure to check:
- 🔍 Backlash in the drive (only the minimum is allowed, up to 0.3 mm).
- 🔍 Tightness clamps (blow into the boot - no air should come out).
- 🔍 Rotation angle wheels (should be smooth, without jamming).
⚠️ Attention! If, after replacing the boot, vibration appears at speeds of 80+ km/h, most likely you tightened the hub nut or the CV joint was damaged during installation. Stop immediately and check the tightening torque!
Cost of work at a service station vs independent replacement
In services for replacing the CV joint boot with Škoda Rapid they charge from 2,500 to 4,000 rubles (depending on the region). If the grenade itself needs to be replaced, the price will rise to 6,000–8,000 rubles. Self-replacement will only cost the cost of spare parts:
| Spare part/work | STO (rub.) | On your own (RUB) |
|---|---|---|
| Outer CV joint boot | Included in work | 800–1 800 |
| CV joint lubrication | Included in work | 300–500 |
| Clamps (set) | Included in work | 200–400 |
| Hub nut | Included in work | 150–300 |
| Total | 2 500–8 000 | 1 450–3 000 |
The savings are obvious, but remember: if you have never worked on a chassis, the risk of mistakes is high. In this case, it is better to pay for the work at the service station, but control the process (for example, ask to see the removed boot and CV joint).
Replacing the boot yourself is justified if you have a torque wrench and experience working with suspension. Without this, the risk of damaging the CV joint or hub is too great.
How to extend the life of a new boot
Even a high-quality boot will not last long if you do not follow simple rules:
- 🚗 Avoid abrupt starts with the wheels turned out, this is the maximum load on the CV joint.
- 🚗 Wash the wheel arches in winter, salt and reagents corrode the rubber of the boot.
- 🚗 Check the anthers every 10,000 km or before long trips.
- 🚗 Use only specialized lubricant for CV joints (not Litol or Solidol!).
If you often drive off-road, install protective fender liners - they will reduce the ingress of sand and stones onto the anthers. It is also worth paying attention to reinforced anthers from GKN or SKF - they are thicker than standard ones and last longer.
On Škoda Rapid with motors 1.4 TSI and 1.6 MPI The service life of the anthers is 60–80 thousand km with careful operation. If you notice even small cracks, do not delay replacement - repairs will cost less than replacing the entire CV joint.
FAQ: Frequently asked questions about replacing the CV joint boot
Is it possible to drive with a torn boot if the CV joint is not crunching yet?
No! Even if there is no crunch, dirt and moisture are already getting into the CV joint. After 500–1,000 km you will hear a crunch, and after another 1,000–2,000 km the grenade will fall apart. The maximum that can be done is to temporarily wrap the boot with electrical tape. (only for driving home!).
What kind of lubricant can replace the original one for the CV joint?
Suitable lubricants based on molybdenum or lithium soap with temperature resistance up to +150°C. The best analogues:
- LIQUI MOLY LM47 — universal, suitable for all types of CV joints.
- Castrol Optitemp LM - high temperature resistance.
- Molykote BR2 Plus - used on conveyors VW Group.
Do not use Litol-24 or Solid oil — they cannot withstand loads and temperatures!
Is it necessary to change the boot of the inner CV joint if only the outer one is torn?
Not necessary, but It is recommended to inspect. The inner boot suffers less often, but if it has microcracks, it is better to replace both at once. This will save time and money in the future. On Rapid The inner boot is changed only when the axle shaft is removed (the oil from the gearbox must be drained).
Is it possible to replace the boot without removing the axle shaft?
Technically you can, but only if you have special tool for disassembling the CV joint directly on the car. However, this is extremely inconvenient and is fraught with errors (for example, dirt getting into the grenade). We recommend removing the axle shaft completely - this way you can properly clean and lubricate the CV joint.
What should I do if a crunching sound appears after replacing the boot?
This means that:
- you damaged separator or balls CV joint during disassembly.
- Hit by a grenade dirt or sand (insufficient cleaning before assembly).
- The CV joint was already worn out, and replacing the boot did not solve the problem.
In this case it is necessary to remove the axle shaft and check the CV joint. If the grenade crunches, it will have to be replaced.
