Knocking Noise in Hillsboro, KS
The short answer
A knock that speeds up when you rev the engine needs looking at quickly, while a knock that only happens over bumps is usually a worn suspension part.
You hear it coming off the highway into Hillsboro, a deep, steady knock from under the hood as you climb the overpass, or a hollow knock from a front corner on every washboard stretch of gravel. Those are very different problems, so bring it in, or we will come and get it.

Text us which onesHow we track down a knock
We find out which knock you have first. A worn sway bar link and a worn engine bearing can both be called a knock, and one is a small repair while the other is a big decision.
If it is the suspension, we replace the worn part and check the alignment. If it is the engine, we explain what is going on in plain words and lay out the options honestly.
We tell you what it costs before we start. Nothing gets done until you say so.
Then we drive it again. The knock should be gone before you pick it up.

Can I keep driving?
Depends where it comes from. If it is the engine, stop.
A knock from the suspension is usually safe for short, careful trips while you book in, as long as the steering feels normal. A deep knock from the engine is different: driving on it can turn a repairable engine into a replacement. If you are not sure which you have, park it and call, and we can come and get it.
Stop driving and call us if
- The knock follows the engine's speed and gets louder
- The oil pressure light comes on, or the oil is low
- The check engine light is flashing
- The steering feels loose or wanders along with the knock

What causes knocking noises around here
- Low or old oil, which lets engine parts knock against each other
- Carbon build-up and the wrong fuel, which can make an engine knock under load
- Washboard gravel roads and potholes, which wear suspension joints and links
- Towing and hauling, which work U-joints, mounts and leaf springs hard
- Rubber bushings cracked by years of heat and cold
How we diagnose a knocking noise in Hillsboro
- We rev the engine in Park to find out whether the knock follows the engine or the road.
- If it is the engine, we check the oil level and pressure and read any stored trouble codes.
- We listen to the engine with a mechanic's stethoscope to find which part of it is knocking.
- If it only knocks while moving, we lift the vehicle and check every suspension and driveline joint for play.
- Then we show you what we found and what your options are.

Knocking noise questions we hear every week
How do I tell an engine knock from a suspension knock?
Rev the engine while the car is parked. If the knock speeds up with the revs, it is in the engine. If it only happens when you drive over bumps or turn, it is almost always the suspension or steering.
Will a thicker oil or an additive fix an engine knock?
It might make it quieter for a while, but it will not fix the worn part. Sometimes the knock is simply from low or old oil, which is why we check that first. A real bearing knock needs a proper repair, and the sooner it is caught the more options you have.
Is it safe to drive with a knock over bumps?
For short trips it usually is, as long as the steering feels normal. The worn part is often a sway bar link, which is not urgent, but it could also be a ball joint, which is. Get it checked soon, and text us right away if the steering starts to feel loose.
