Steering rack boot damaged? We replace it and re-inspect your car
Does your APK (MOT) report say “Stofhoes stuurinrichting beschadigd, dicht niet af” (steering rack boot damaged, no longer seals)? Then your car has failed on that point. Here you can read what it means, whether you can still drive and how we fix it. Autobedrijf Willemsbrug is an RDW-approved APK station in Rotterdam-IJsselmonde. We replace the boot, align the wheels in our own workshop and then re-inspect your car.
Our score is 4.8 / 5 from 235 reviews. Read what our customers say.
The short answer
The steering rack boots, also called gaiters, are two rubber concertina boots, one on the left and one on the right of the steering rack. They keep dirt and water out of the rack. “Dicht niet af” (no longer seals) means that a boot is torn, perished or loose. Dirt and water then reach the rack. In the APK that is a reason for failure.
The fix is usually a new boot with new clips. To fit it, we disconnect the track rod end and unscrew it from the track rod. After that we align the wheels, because this can change the toe. If your car failed with us, we re-inspect it after the repair and register the APK result with the RDW. Call +31 10 479 00 00 with your registration number. We then tell you the cost in advance.
What does your APK report say?
The inspection report describes the defect in a short, standard sentence. These are the most common sentences about boots, and what they mean.
| Text on the report | Which part | What we usually do |
|---|---|---|
| Stofhoes stuurinrichting beschadigd, dicht niet af (steering rack boot damaged, no longer seals) | The concertina boot on the steering rack, around the track rod | New boot with new clips, then wheel alignment |
| Stofhoes fuseekogel beschadigd en dicht niet af (ball joint boot damaged and no longer seals) | The small rubber boot around the ball joint, the pivot at the bottom of the wheel | Check the ball joint and usually replace it completely |
| Stofhoes stuurkogel of spoorstangeind beschadigd (track rod end boot damaged) | The boot around the ball joint at the end of the track rod | Replace the track rod end, then wheel alignment |
During the APK the inspector looks at the boots from under the car. The tear is often small and sits in a fold of the concertina. You usually cannot see it yourself. Do you want to see what was reported at an earlier inspection? With your registration number you can find the APK details at the RDW vehicle information service.
What does the steering rack boot do?
When you turn the steering wheel, a toothed rack moves back and forth inside the steering rack housing. On each side a track rod turns the wheels. Where the track rod comes out of the housing, there is a rubber concertina boot. It moves with the steering and keeps out dirt, salt and water.
Rubber ages through heat, cold and road salt. Over time small cracks appear, especially in the folds. A clip that has come loose can also stop the boot from sealing properly.
What happens if you leave it?
A torn boot is not immediately dangerous. But dirt and water get into the steering rack through the opening. In the long run that costs more:
Do you already notice play in the steering, vibration or a ticking noise? Then also read what the cause can be when your steering wheel vibrates.
Can I still drive after failing?
Yes, until the expiry date of your current APK. A fail does not invalidate your current APK. You do have to have the defect repaired and the car re-inspected before the expiry date.
Has your APK already expired? Then in principle you may no longer drive the car on the road. According to the ANWB, in the two months after expiry you may only drive to the garage if you have an appointment. Without an appointment, or more than two months after expiry, you can be fined. Read more about what to do if your car has failed the APK.
So do not wait too long. Replacing a boot is usually sorted quickly, if you call in time.
How we replace the boot
Is the boot on the other side also old or perished? Then we sometimes advise replacing both sides at the same time. We discuss that with you first. Extra work is only done with your approval.
What does it cost to replace a steering rack boot?
The price varies per car. These are the main things that decide what you pay:
This is how it works with us. Call +31 10 479 00 00 with your registration number and the text from the inspection report. You then receive a quote in advance, including VAT and wheel alignment. Our repairs come with a warranty. When we give you the quote, we tell you which warranty applies.
Did your car fail at another garage? You are welcome with us too. We repair the defect and do a new APK at our standard rate: € 50 for a petrol car, petrol hybrid or electric car and € 60 for a diesel with a factory-fitted particulate filter (DPF). If we repair the items that failed, we will also arrange the retest. We will tell you the cost of the repairs and the retest in advance. Do you think the car should not have failed? Then you can also ask for a second opinion.
Stofhoes fuseekogel beschadigd en dicht niet af (ball joint boot damaged and no longer seals)
This is a different part, but it also comes up often in the APK. The ball joint is the pivot at the bottom of the wheel, between the wishbone and the steering knuckle. It has a small rubber boot around it with grease inside.
If that boot is torn, the grease runs out and dirt and water get into the joint. The joint then wears quickly and develops play. That is why we usually replace the complete ball joint. On many cars the joint is part of the wishbone, and then we replace the wishbone. If only the boot is available separately and the joint is still good, we discuss that with you.
The same applies here: we tell you the cost in advance. If the manufacturer asks for an alignment after this work, it is included in the quote straight away.
