2020 Ford F-150 Vibration? Troubleshooting Lights & Wiring

What You're Dealing With

A vibration in your car is more than just an annoyance—it's your vehicle's way of telling you something is out of balance or wearing out. This isn't one specific problem but a symptom with a wide range of possible causes, from simple fixes you can handle in your driveway to more complex mechanical issues. The key is paying attention to when and where you feel the shake to help narrow down the culprit.

What Drivers Report

Based on an analysis of 100 owner discussions, vibrations are a very common complaint, but the experiences vary widely. Many drivers report the issue starting subtly and getting worse over time. A frequent theme is misdiagnosis; owners often spend money on one repair (like wheel balancing) only to find the vibration persists, leading them to investigate other systems. The community heavily emphasizes the importance of noting specific details: Does it happen at certain speeds? Only when braking? Is it in the steering wheel, seat, or the whole car? These clues are invaluable.

What You'll Notice

You'll feel vibrations as a rhythmic shaking or shuddering. The location of the sensation is your first major clue:

• Steering Wheel Vibration: Most often reported at highway speeds (55-70 mph). This typically points to issues with the front wheels or tires.
• Seat or Floorboard Vibration: A shake you feel through your body or feet, especially at lower speeds. This often points to the rear wheels, driveshaft, or exhaust system.
• Whole-Car Shake: The entire vehicle shudders. This can be due to severe tire issues, engine mounts, or driveline problems.
• Vibration When Braking: A pulsation or shake that only happens when you press the brake pedal usually indicates warped brake rotors.

Underlying Issues

From the community reports and successful fixes, the causes break down into a few common categories. The parts mentioned most frequently align with these issues.

1. Tire & Wheel Issues (Most Common): This is the #1 cause of speed-sensitive vibrations. It includes unbalanced tires, out-of-round tires, damaged belts inside the tire, or even a shifted tire tread. Proper mounting and balancing are critical.
2. Brake System Problems: Warped front brake rotors are a prime suspect for vibrations that occur specifically during braking. The rotor surface becomes uneven, causing the brake caliper to pulse.
3. Driveline Imbalance: This refers to the components that spin to deliver power to the wheels. An unbalanced driveshaft or a worn constant velocity (CV) joint can cause significant shaking, often felt in the seat or floor.
4. Engine/Accessory Issues: Worn engine mounts can let normal engine vibration transfer into the chassis. A damaged or unbalanced cooling fan or other accessory pulley can also create a shake, often noticeable at idle.
5. Suspension & Steering Components: While less frequently the sole cause in initial reports, worn parts like tie rods, ball joints, or control arm bushings can contribute to or exacerbate vibration, especially when combined with tire issues.

Fix Guide

Start with the simplest and most common fixes before moving to more involved and expensive repairs.

1. Tire Inspection and Rebalancing (First & Cheapest Step) This solved a large portion of the cases discussed. Have your tires checked for uneven wear, bulges, or damage. Then, get them professionally balanced. Many owners reported this alone fixed their highway-speed steering wheel shake. It's also wise to have the tire shop check for "road force variation," which can find a tire that is balanced but still out-of-round.

2. Brake Rotor Service If the vibration happens when braking, your rotors are the likely suspect. The fix is to have the rotors resurfaced (if enough material remains) or replaced. Always replace or resurface rotors in axle sets (both fronts or both rears).

3. Driveline Inspection For vibrations felt in the seat/floor at specific speeds (often 45-55 mph or 70+ mph), have a mechanic check the driveshaft (on RWD/AWD vehicles) for missing balance weights or worn universal joints. For front-wheel drive, have the CV axles inspected for wear.

4. Check Engine and Transmission Mounts If the vibration is worst at idle or low speeds and you feel it throughout the car, a broken engine mount could be letting the engine shake excessively. A visual inspection can often reveal a cracked or collapsed mount.

5. Suspension and Steering Check If the above steps don't resolve it, a thorough inspection of suspension and steering components is needed. Worn parts won't hold alignment properly, leading to tire wear and vibration.

Pricing Guide

Costs can vary dramatically based on your vehicle and location.

• Tire Balancing: $20 - $50 per axle for a shop. A DIY balancer is not cost-effective; this is a professional job.
• Brake Rotor Replacement: Parts: $50 - $150 per rotor. Labor: $150 - $300 per axle. DIY Potential: High for mechanically inclined owners with proper tools.
• Driveshaft Balancing/Replacement: Shop Labor & Parts: $300 - $800+. This is rarely a DIY job due to the need for precise balancing.
• Engine Mount Replacement: Parts: $50 - $250 per mount. Labor: $150 - $500 depending on mount location. DIY Difficulty: Medium to High (some mounts are very accessible, others require significant disassembly).
• Suspension Component Replacement (e.g., Tie Rods, Control Arms): Parts: $100 - $400 per corner. Labor: $200 - $600+. DIY Difficulty: Medium (requires an alignment afterward).

General Rule: Always get a professional diagnosis after the simple tire/brake checks. Paying for one hour of diagnostic labor ($100-$150) can save you hundreds by correctly identifying the problem the first time.

Reader Questions

Q: My car vibrates at 65 mph, but it's smooth at 70 mph. What does that mean? A: This is a classic sign of a tire or wheel balance issue. Imbalances resonate at specific speeds. The fact that it gets better at a higher speed points directly to a need for rebalancing.

Q: I just got new tires and now I have a vibration. What happened? A: This is commonly reported. New tires can have slight imperfections or may not have been balanced correctly. Go back to the shop and ask them to re-check the balance and ensure the tires are mounted correctly on the rim. A poorly seated bead can also cause this.

Q: Could it be my wheel bearings? A: While a severely worn wheel bearing can cause vibration, it's almost always accompanied by a loud growling or humming noise that changes with speed. Vibration alone is less likely to be a bearing.

Q: Is it safe to drive with a vibration? A: It depends on the severity. A slight steering wheel shake is likely a balance issue and may be okay for short trips. However, a severe shake, especially one that is getting worse, can lead to accelerated wear on suspension and steering components and could be a safety hazard. Get it checked promptly.
