If vibration occurs at high speeds immediately after vehicle inspection.

“I just had my car inspected, but now it’s vibrating at high speeds…” This
is a question we sometimes hear from Volkswagen, and it’s not uncommon for the symptoms to worsen after maintenance

. Since inspections involve many procedures, such as tire removal and suspension inspections, even slight misalignments or differences in assembly can become very noticeable at high speeds.

This article clearly summarizes the main causes of vibrations after vehicle inspections and what to check.
If you’re concerned about a vibration at high speeds, be sure to check this out.

Common symptoms

• There was no problem before the vehicle inspection, but now it shakes only on the highway.
• Shaking occurs at speeds of 80 to 120 km/h
• The steering wheel vibrates slightly
• Became stronger after tire change/rotation
• Unable to change lanes
• At low speeds it’s barely noticeable

There are four main causes (by structure):

• Wheel imbalance (prone to occur after removal and installation)
• The alignment has gone wrong and the original misalignment has become apparent
• Effect of tire mounting direction and rotation
• The undercarriage bush joints are overloaded and malfunctions become apparent.

Cause 1: Wheel imbalance (most common after vehicle inspection)

When does it happen?

• Shaking occurred at high speeds after the tire was removed.
• Remove the wheel nuts and reassemble
• Rotation was performed

Why do symptoms occur?

Since vehicle inspections often involve removing tires, VWs are
prone to slight imbalances simply by “removing” and then “attaching” the tires .

• The mounting position has changed slightly
• Centering is poor
• The balance weight came off
• The rotation put the front wheel in a bad position.

When these factors are combined, a vibration occurs around 100km/h.

What if you leave it alone?

• The vibration becomes stronger
• Accelerates uneven tire wear
• Increased strain on the steering system

Cause 2: Misalignment (may become apparent during vehicle inspection)

When does it happen?

• After the vehicle inspection, the car is not stable when going straight.
• The steering wheel seems to be off center
• Wobbling and shaking occur simultaneously at high speeds

Why do symptoms occur?

Alignment misalignment will become apparent during vehicle inspection if the following factors are present:

• I loosened the bolts around the suspension and inspected them.
• Lifting the suspension resets the “habit” of the stuck bushings.
• The difference between the left and right sides was emphasized by the rotation.

This is a pattern in which the alignment, which was originally within the “barely acceptable range,” is disrupted, resulting in instability and shaking at high speeds .

What if you leave it alone?

• Straight-line stability deteriorates
• Rapid uneven tire wear
• Steering is tiring

Cause 3: Impact of tire mounting and rotation

When does it happen?

• I swapped the front and rear tires during the vehicle inspection.
• There is wear on the inside and outside.
• The worn-out tire was moved from the rear to the front

Why do symptoms occur?

When a tire that was originally in a bad condition moves to the front wheel due to rotation, the vehicle
will suddenly experience more severe shaking at high speeds.

• Step reduction → Vibration at high speed
• Uneven wear → Steering becomes less stable
• Old tires → unstable contact with the ground

The effects of uneven wear are particularly noticeable in VWs, and this is a very common cause of sudden shaking after a vehicle inspection.

What if you leave it alone?

• The decrease in size has worsened
• Decreased stability on rainy days
• Vibrations spread throughout the vehicle

Cause 4: When deterioration of the suspension bush joints becomes apparent

When does it happen?

• No notice given during vehicle inspection
• Not noticeable at low speeds
• The shaking is large only at high speeds

Why do symptoms occur?

By lifting the undercarriage,

• The “twist” of the stuck bush is restored.
• The play in deteriorated parts increases.
• The original rattle becomes apparent

This can result in increased vibration.

The Golf and Passat series in particular are prone to high-speed instability due to deterioration of the lower arm bushings.

What if you leave it alone?

• Worsening instability
• There is a strange noise around the suspension
• Induces uneven tire wear

DIY checks

• Tire pressure (check difference between left and right)
• Is the balance weight loose?
• Tire condition after rotation (wearing unevenly or unevenly)
• Steering wheel center misalignment
• Tightening wheel nuts

Risk and whether it is possible to drive

When driving trouble occurs, towing may be necessary depending on the situation.
In such cases, road service or special clauses in your car insurance may be able to cover the cost, so it’s a good idea to take a quick look at your current contract to make sure you’re covered .

If you’re worried that you might not have fully understood the scope of your insurance coverage, you can use a comparison service to check the coverage and premiums of multiple companies at once . Since you can get an overall picture in a short amount of time, many people use this service when it comes time for repairs or inspections.

Areas that should be inspected at the same time

• Lower arm bush
• Tire wear that is uneven or uneven
• Wheel balancing
• Alignment (especially toe angle)
• Play around the hub

summary

High-speed vibrations immediately after a vehicle inspection are often caused by the combined effects of wheel balance, alignment, and rotation.

Changes caused by these work are easily detected, so if you notice anything unusual, it’s best to have it checked again as soon as possible.

Shaking at speeds around 100km/h, in particular, should not be ignored.

Even if the symptoms are similar, the cause will vary from vehicle to vehicle.
Even if the same strange noise or malfunction occurs, there may be various causes, such as turbo, belt, or sensor.

If you are unsure, it is best to have it checked at a repair shop.

Details of defects by vehicle type

Even if the “way” of the malfunction is similar, “which model has the most common problems” differs slightly depending on the model.

The following page summarizes the trends by model and common malfunction cases among other owners.

Frequently Asked Questions (FAQ)

Q1. If vibrations occur at high speeds immediately after vehicle inspection, are there any points I can check myself first?
A. You can check for things like left and right air pressure differences, missing balance weights, uneven tire wear after rotation, misalignment of the steering wheel center, and loose wheel nuts. If you notice any abnormalities, take your car to a repair shop.

Q2. Is it true that there was no vibration before the vehicle inspection, but suddenly the vibration starts after maintenance?
A. Yes. Tire removal and installation, tire rotation, and suspension inspections often bring to light areas that were already at their limits. VWs in particular tend to be affected by balance and uneven wear.

Q3. If vibrations only occur at high speeds, how dangerous is it? Is it safe to drive?
A. If there is a clear vibration at around 100km/h, the risk is high. We recommend avoiding high-speed driving and having your bike inspected early. Even a minor imbalance can cause uneven wear if driven for a long period of time.

Q4. What is the difference between wheel balance and alignment? Which should you check first?
A. Wheel balance is the “weight imbalance of the tire itself,” while alignment is the “angle of the entire suspension of the car.” If you notice vibrations soon after a vehicle inspection, the first thing to suspect is often the balance.

Q5. Should I take it back to the same workshop where I had it inspected? Should I have it looked at at another workshop?
A. The basic rule is to first inform the workshop that inspected the car of the situation. If you can’t identify the cause or you are unfamiliar with imported cars, taking it to a workshop that specializes in VWs will often result in a quicker diagnosis.
