Have you ever driven over rumble strips on the side of the road? If you have, you know how they make your car vibrate and produce a loud noise. But what if you feel the same sensation when accelerating, even on a smooth road? That could indicate a problem with your vehicle that needs your attention.
Continue reading as we explore some common causes of when feels like rumble strips when accelerating. We will also give you some tips on how to diagnose and fix the problem or when to seek professional help.
Feels Like Rumble Strips When Accelerating – Causes
Rumble strips are a road safety feature used to alert inattentive drivers of potential danger, causing a tactile vibration and audible rumbling transmitted through the wheels into the vehicle interior. They are usually applied along the direction of travel following an edge line, centerline, or across the direction before a hazard. Some common causes of feeling like rumble strips when accelerating are:
- Tire problems: Your tires could be damaged, unevenly worn, or out of balance, causing vibrations and noises when you speed up.
- Transmission issues: Your transmission could be slipping, shuddering, or failing, resulting in a jerky or rough acceleration. The transmission mount could also be worn out, causing the transmission to move excessively during hard acceleration or braking.
- Engine misfires: Your engine could be misfiring due to faulty spark plugs, ignition coils, fuel injectors, or other components, causing a loss of power and a rumbling sound when accelerating.
- Other possible causes: Some other factors that could make your car feel like driving over rumble strips are worn-out rotors, defective wheel bearings, and bent or imbalanced drive shafts.
How to Diagnose And Fix Rumble Strip Feeling When Accelerating
- Check the tires
Inspect the tires for any damage, uneven wear, or low pressure. Rotate or replace the tires if needed. Also, check the lug nuts and make sure they are correctly tightened.
- Balance the wheels
Use a wheel balancer to check if the wheels are out of balance. If they are, add or remove weights to balance them.
- Replace the rotors
If you feel the vibration when braking, your rotors could be warped or worn out. Replace them with new ones.
- Buy new wheel bearings
Your wheel bearings could be defective for any growling noise when driving straight or cornering and need replacement.
- Replace the transmission mount:
If vibration occurs during hard acceleration or braking, your transmission mount could be worn out. Replace it with a new one.
- Replace the transmission fluid:
If dirty, contaminated, or low, it could cause your transmission to slip, shudder, or fail. Drain the old fluid and refill it with new fluid.
- Replace the torque converter:
If your torque converter shudders, it could cause a rumble strip feeling when accelerating. Replace it with a new one.
- Replace the drive shafts:
If your drive shafts are bent, imbalanced, or have damaged U-joints, they could cause a vibration underneath your car. Replace them with new ones.
- Inspect the radiator:
If coolant is getting into your transmission fluid through the radiator, it could cause many problems. Check the radiator for any leaks or corrosion and replace it if needed.
How to Avoid Feeling Like Rumble Strips
- Maintain your tires
Check your tire pressure regularly and keep them inflated to the recommended level. To guarantee even wear on your tires, rotate them every 5,000 to 10,000 miles. Replace your tires when they are worn out or damaged.
- Align your wheels
Have your wheels aligned by a professional mechanic at least once a year or whenever you notice your car pulling to one side or the steering wheel shaking. The alignment will ensure your wheels are parallel and perpendicular to the road.
- Service your transmission
Change your transmission fluid and filter every 30,000 to 60,000 miles or according to your owner’s manual. Buy the appropriate type of fluid for your transmission. Add a shudder fix additive to your transmission fluid if you experience a torque converter shudder.
- Inspect your suspension system
Check your shocks, struts, springs, bushings, and other suspension components for any signs of wear or damage. Replace them if needed. A sound suspension system will absorb the road vibrations and provide a smooth ride.
- Avoid driving over rumble strips
Rumble strips alert you when drifting out of your lane or approaching a hazard. They are not meant to be kept from being driven over regularly. If you encounter rumble strips, slow down and safely return to your lane.
Consequences of Driving When it Feels Like Rumble Strips
- Damaging your vehicle: Driving in this state can accelerate wear and tear on your tires, suspension system, shock absorbers, and wheels. It can also damage your transmission, drivetrain, brakes, and other components if the problem is not fixed. This can lead to costly repairs or even a breakdown in the future.
- Compromising your safety: Driving with the feeling of rumble strips can affect your handling and braking performance, making it harder to control your vehicle and avoid collisions. It can also distract you from the road and cause you to lose focus or drift out of your lane. That can increase the risk of accidents and injuries for you and others on the road.
- Violating the law: It can be a sign of a poorly maintained vehicle that does not meet the safety standards required by law. If caught driving a car unsafe or unfit for the road, you may attract fines or get ticketed.
Is it safe to continue driving when it feels like going over rumble strips?
It is unsafe to continue driving your vehicle when it feels like going over rumble strips. This sensation could indicate a severe problem with your tires, suspension system, drivetrain, or brakes. Driving with these issues could compromise your safety and cause further damage to your vehicle. It would help to have your car inspected and repaired by a professional mechanic as soon as possible.
When braking, can a warped brake rotor cause a rumble strip feeling in my car?
A warped brake rotor can cause a rumble strip feeling when braking, especially at high speeds. It will create uneven contact with the brake pads, resulting in pulsations and vibrations that can be felt in the brake pedal and the steering wheel. It’s a sign that you must replace your brake rotors with new ones.
How often should I inspect my car’s suspension components to prevent the rumble strip feeling?
You should inspect your car’s suspension components at least once a year or whenever you notice any signs of wear or damage, such as noises, vibrations, leaks, or poor handling. A sound suspension system will absorb the road vibrations and provide a smooth ride.
Can a failing wheel bearing cause it to feel like rumble strips?
A failing wheel bearing can cause a growling noise and a vibration when driving straight or cornering. The noise and vibration will usually increase with speed. To check if your wheel bearing is bad, jack up your vehicle and spin the wheel by hand. If you hear any grinding or scraping noises, or if the wheel wobbles or has any play, your wheel bearing needs replacement.
When it feels like rumble strips when accelerating, it is annoying and dangerous. It can indicate a severe issue with your car that needs your immediate attention.
