Outdoor CV joint (constant velocity joint) - one of the key elements of the drive mechanism Škoda Rapid, responsible for transmitting torque to the wheels at an angle. Its wear or damage leads to a characteristic crunch when turning, vibrations and deterioration in handling. Unlike the internal CV joint, the external one fails more often due to increased loads and exposure to the external environment.
In this article we will look at how replace the outer CV joint on a Škoda Rapid yourself (including models Spaceback and Liftback), without resorting to the services of a service station. You will learn what tools you will need, how to choose the right spare part, and receive step-by-step instructions with nuances that you will not find in standard manuals. We will pay special attention to typical errors that can shorten the life of the new hinge or damage adjacent units.
Signs of a faulty outer CV joint on a Škoda Rapid
The first symptoms of a problem with external CV joint often ignored until the crunch becomes clear. However, delay is fraught with destruction of the hinge and damage to the axle shaft. Here are the key signs that require diagnosis:
- 🔊 Crunch when turning (especially at full turn of the steering wheel) - a classic symptom of wear on the balls or CV joint race. The sound gets louder when accelerating.
- 🌀 Vibration on the steering wheel when accelerating or driving at a speed of 60–80 km/h, which disappears when braking the engine.
- 🛑 Jerks at start or slipping - indicate play in the hinge or damage to the boot.
- 💨 Lubricant on the inside of the wheel - a consequence of a rupture of the boot and leakage of grease.
It is important to distinguish between faults outdoor CV joint from internal: the first one “crunches” when turning, the second one when driving in a straight line with a load (for example, when overcoming holes). For an accurate diagnosis, jack up the car, lock the brake and swing the wheel in a vertical plane. Play of more than 1–2 mm is a reason for replacement.
⚠️ Attention: If you ignore the crunch of the CV joint, its race may split, and the balls may damage the axle shaft. Repair in this case will cost 2–3 times more than timely replacement of the hinge.

Selection of spare parts: original vs analogues for Škoda Rapid
When purchasing new CV joint for Škoda Rapid It is important to consider not only the brand, but also catalog number, which depends on the year of manufacture and type of drive. Original parts from VW Group are indicated by articles:
- 🔧 1J0 498 101 — external CV joint for models up to 2017 (1.2/1.4 TSI, 1.6 MPI engines).
- 🔧 5Q0 498 101 - for restyled versions (2017–2023) with 1.0 TSI and 1.6 TDI engines.
- 🔧 1Z0 498 101 — for all-wheel drive modifications (4x4).
The cost of the original CV joint is from Škoda or VW — 8,000–12,000 rubles. Alternative brands with a good reputation:
| Brand | Article | Price, rubles | Features |
|---|---|---|---|
| GKN (Loebro) | ADB00134 | 5 500–7 000 | High quality bearings, supplier for VW conveyor |
| SKF | VKJA 7636 | 6 000–8 500 | Reinforced anthers, service life up to 150,000 km |
| Febi | 24321 | 4 000–5 500 | Budget option, suitable for a quiet ride |
| Hola | NB4001 | 3 500–4 800 | Chinese production, short resource (up to 50,000 km) |
A critical nuance: when purchasing an analogue, be sure to check the presence of anther in the kit. Cheap CV joints are often supplied without it, and the original boot from Škoda (article 1J0 498 283) costs separately 1,200–1,500 rubles.
Advice: if you plan to replace it yourself, choose a CV joint with pre-lubrication (usually marked on the packaging). This will save time and eliminate errors when applying grease.
Necessary tools and preparation for replacement
To replace the outer CV joint with Škoda Rapid No specialized equipment is required, but some tools are indispensable. Here's the full list:
- 🔧 Jack and supports (or a lift) - it is strictly not recommended to work on one jack!
- 🔧 Socket heads by 13, 16, 17 and 19 mm (for hub bolts and CV joint fastenings).
- 🔧 Impact screwdriver or
WD-40- for unscrewing stuck hub bolts. - 🔧 CV joint puller (or pry bar + hammer) - to remove the hinge from the axle shaft.
- 🔧 Torque wrench — for tightening the hub bolts with a torque of 90–110 Nm.
- 🔧 Pliers and clamps - for fixing the boot.
Also prepare:
- 🧴 Grease (for example, Molykote BR2 Plus or LIQUI MOLY LM47) - 100–150 g.
- 🧹 Rags and solvent (for cleaning seats).
- 🛡️ Protective gloves — lubricant has an aggressive effect on the skin.
⚠️ Attention: If on your Rapid alloy wheels are installed, use plastic spacers when unscrewing the hub bolts. A metal tool may damage the platter.

Step-by-step instructions for replacing the outer CV joint
The replacement process takes 2-3 hours if you have experience. If this is your first time doing this, be patient and follow the instructions strictly point by point.
Step 1: Removing the Wheel and Hub
1. Raise the car with a jack and remove the wheel. Make sure the machine is on supports!
2. Unscrew bolt securing CV joint to hub (19 mm head). If the bolt is stuck, use an impact screwdriver or heat it with a hair dryer.
3. Disconnect brake caliper (two 13 mm bolts) and hang it on a wire so as not to damage the hose. Remove the brake disc.
Step 2: Removing the old CV joint
1. Unscrew three bolts securing the CV joint to the axle shaft (16 mm head). It may be necessary to keep the axle shaft from turning with a pry bar.
2. Using a puller or gentle blows of a hammer through a wooden spacer, knock the CV joint off the axle shaft. Don't hit the hinge itself! - this may damage the seat.
3. Remove retaining ring from the axle shaft (use pliers) and clean the splines of old grease.
What to do if the CV joint cannot be removed?
If the hinge is stuck to the axle shaft, treat the joint with penetrating lubricant (WD-40 or Liqui Moly Rostloser) and leave for 10–15 minutes. Then gently tap the CV joint eyes through the copper or aluminum spacer. Do not apply force to the joint body as this may deform the cage.
Step 3: Installing a new CV joint
1. Put on new boot onto the axle shaft and secure it with a small clamp. If the boot is included, check it for cracks.
2. Apply lubricant onto the axle shaft splines and the inside of the new CV joint. Use special lubricant for CV joints - regular "Litol" is not suitable!
3. Install retaining ring onto the axle shaft and push the new CV joint until it clicks. Make sure it's seated all the way.
4. Fasten the CV joint with bolts to the axle shaft (tightening torque - 40–50 Nm) and secure the boot with a large clamp.
Step 4: Assembly and Testing
1. Install the brake disc and caliper, tighten the bolts (torque - 30–35 Nm).
2. Put on the wheel and lower the car. Only tighten the hub bolts with the machine lowered! (torque - 90–110 Nm).
3. Check the operation: drive 50–100 meters with the steering wheel turned completely. There shouldn't be any crunch.
After replacing the CV joint, avoid sudden starts and off-road driving for the first 100 km. This will allow the new lubricant to be evenly distributed throughout the joint.
Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes that reduce the life of a new CV joint or lead to repeated repairs. Here are the most common:
- 🔧 Insufficient lubrication — leads to accelerated wear of the balls and races. Needs to be filled with lubricant the entire internal cavity CV joint (about 80–100 g).
- 🔧 Boot damage during installation. Even a microcrack will lead to dirt getting in and the joint to fail within 5,000–10,000 km.
- 🔧 Incorrect tightening torque hub bolts. Weak tightening leads to backlash, excessive tightening leads to flange deformation.
- 🔧 Using the wrong lubricant. Graphite or lithium grease does not withstand the loads in the CV joint and is washed out within 20,000–30,000 km.
- 🔧 Ignoring the retaining ring. Without it, the CV joint may jump off the axle shaft during sudden acceleration.
Another common problem is confusion of left and right CV joints. On Škoda Rapid they are visually similar, but have different spline lengths. Please check the catalog or an old hinge before purchasing.
⚠️ Attention: If, after replacement, vibration appears at speeds of 80–100 km/h, check the wheel balancing and the condition of the wheel bearing. Vibration is not always associated with the CV joint!
When to contact a service station: cases when amateur activity is dangerous
Although replacing the outer CV joint with Škoda Rapid is considered a task of medium complexity, there are situations when it is better to trust the professionals:
- 🔧 No experience with suspension. Mistakes during disassembly may result in damage axle shafts or ABS sensor.
- 🔧 The hub bolts are stuck, and they cannot be unscrewed without the risk of stripping the thread. Service stations use pneumatic tools and special attachments.
- 🔧 The inner CV joint needs to be replaced or the entire axle shaft. This process is more complicated and requires removing the transmission.
- 🔧 After replacement there was a crunching sound. This may indicate wear tripoid bearing (inner CV joint) or problems with the gearbox.
The cost of replacing an outer CV joint at a service station for Škoda Rapid — from 2,500 to 4,000 rubles (excluding spare parts). If you are not confident in your abilities, it is better to overpay for the work than to risk safety.
The main criterion for a successful replacement is the absence of crunching when turning and vibrations at speed. If the symptoms remain, the problem lies deeper (axle shaft, bearing, box).
FAQ: Frequently asked questions about replacing a CV joint on a Škoda Rapid
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 while driving can block the wheel or damage the axle shaft. At the first sign of crunching, plan to replace it.
How long does a new CV joint last?
The service life of the original CV joint is 100,000–150,000 km. Analogues from GKN or SKF nurse 80,000–120,000 km. The period depends on the driving style and the condition of the anthers.
Do I need to replace the CV joint in pairs?
Not if the second joint is in good condition. Outer CV joints wear independently of each other. The exception is all-wheel drive versions, where symmetrical replacement is recommended.
Is it possible to lubricate the CV joint without removing it?
No. Lubrication requires complete disassembly of the unit. “Adding” grease through a damaged boot will not solve the problem—the hinge and boot will need to be replaced.
What is the difference between CV joints for Rapid Spaceback and Liftback?
Structurally - nothing. Articles and sizes are identical. The only difference can be in the length of the axle shaft for all-wheel drive versions.
