Replacement of the external SRUS on the ŠKODA Octavia: a guide from A to Z

Introduction: when and why you need to replace the external SRUS Škoda Octavia

Outdoor CV joint (constant velocity joint) One of the key elements of the transmission Škoda Octavia, responsible for the transmission of torque to the driving wheels at an angle. Its malfunction not only worsens controllability, but can also lead to serious breakdowns of the drive. Unlike the internal SRUS, the external ("garnet") works in more severe conditions: it is subject to impacts, dirt and moisture, as well as high loads when cornering.

The service life of the outer CV joint is Octavia (depending on the generation-- A5, A7, FL or 4th generation) varies from 80,000 to 150,000 km. However, aggressive driving style, bad roads or damaged anther can reduce this period by 2-3 times. Feature Octavia: on models with 1.8 TSI and 2.0 TSI engines, the external SRUS fail more often due to increased torque. If you hear a characteristic crunch when turning or accelerating, this is the first bell to diagnose.

Signs of malfunction of the external SRUS: how to recognize the problem

Symptoms of wear of external SRUS on Škoda Octavia Often confused with faulty suspension or transmission. However, there are specific signs that will help to accurately identify the problem:

• 🔊 Crunching or clicking noise when turning the steering wheel (especially at full load or at a sharp acceleration). The sound comes from the side of the problem wheel.
• 🌀 Vibration on the steering wheel acceleration to 40-60 km / h, which disappears at higher speeds.
• 🚗 Jerks when starting off It looks like the car is “twitching” to the side.
• 🔧 Backlash in the drive, which can be felt if you sway the wheel in a vertical plane (with the hung wheel).

It is important to distinguish the malfunction of the external SRUS from the internal: the latter usually crunches when moving in a straight line, and the external one - when turning. Nana Octavia A7 with all-wheel drive (4x4) diagnosis is complicated because the sounds may be masked by the clutch Haldex. In this case, the test with hanged wheels will help:

⚠️ Attention: If when the drive shaft is rotated manually heard metal grinding or a "jamming" is felt, the SRUS is already in an emergency condition. Operate the car in this case is dangerous - a break in the shaft on the move is possible!

Step by step: how to replace the external SRUS with Škoda Octavia

The process of replacing the external SRUS is the same for most generations OctaviaThere are some nuances for all-wheel drive versions (4x4). Let's consider a universal algorithm:

Step 1: Dismantling the wheel and the hub nut

1. Raise the car with a jack and remove the wheel.

2. Unscrew the hub nut (moment of tightening -) 280–300 Nm). To do this, you will need to hold the drive shaft with a gas key or the assistant must press the brake pedal.

3. Remove the brake caliper (unscrew two bolts on the 17 mm And hang it on the wire so you don't damage the hose.

Step 2: Remove the drive shaft

1. Then, turn the slacks on the slack to the slack.16 mm).

2. Carefully press the SRUS from the hub with a removable or hammer (hit through a wooden paddle!).

3. Remove the drive shaft from the gearbox. Then, pull it on yourself while shaking it at the same time. Nana DSG It may need to be mounted.

Step 3: Replacement of the SRUS

1. Remove the locking ring from the shaft (use pliers).

2. Install a new SRUS on the shaft, pre-applying lubrication on the slats.

3. Secure the anther with new clamps and fix the locking ring.

Step 4: Assembly

1. Insert the drive shaft back into the gearbox (should click the lock).

2. Install the SRUS in the hub and tighten the hub nut with a dynamometer key.

3. Collect the caliper, the wheel and lower the car.

What if the slug doesn’t come out of the box?

If the drive shaft is jammed in the box, do not make excessive efforts! Remove the anther from the inner SRUS, then gently dent the shaft with a mount through the slot in the box body. Nana Octavia A7 You may need to remove the subframe for access.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the SRUS with a Škoda Octavia. Here are the most common of them:

• 🔧 Improper tightening of the hub nut: if you pull, the bearing of the hub will fail in 5-10 thousand. km. If you do not pull, the wheel will “beat”.
• 🧴 Saving on lubrication: use of the usual Litol-24 instead of specialized lubrication (Molykote BR2 Plus) reduces the service life of the SRUS by 2 times.
• 🔩 Boot damage: When installing a new SRUS, the anther is often pierced with a screwdriver or pliers. This leads to dirt and rapid wear.
• 🚗 Ignoring checking the inner CV jointIf the external SRUS is worn out, the internal SRUS may also require replacement (especially on mileage machines > 120 thousand). km).

Another typical problem is Incorrect installation of the retaining ring. If it is not fixed to the end, the SRUS can jump off the shaft when moving. To avoid this, after installing the SRUS pull on yourself: it should not move from place.
