Vibrating at high speeds, especially on the highway, can be caused by several factors. Here are the most common reasons:
1. Tire Issues:
A) Unbalanced tires: If your tires are not properly balanced, it can cause vibration, especially at higher speeds.
B) Worn or uneven tires: If the tires have uneven wear or are damaged, this can also cause vibrations.
C) Tire pressure: Incorrect tire pressure may lead to vibration. Under- or over-inflated tires can affect handling and ride quality.
2. Wheel Alignment Problems: Misaligned wheels can cause vibration as well as poor handling and uneven tire wear.
3. Suspension or Steering Components:
A) Worn-out shocks or struts: If the suspension components are worn, it can cause vibrations, especially on bumpy roads or at higher speeds.
B) Loose or damaged steering components: Worn tie rods, ball joints, or bushings in the steering system can cause vibrations and handling issues.
4. Driveshaft or Axle Issues:
A) Worn U-joints or CV joints: These components connect the transmission to the wheels. If they are worn or damaged, they can cause vibrations.
B) Bent driveshaft: If the driveshaft is damaged, it may result in vibrations that get worse at higher speeds.
5. Brake Issues:
A) Warped brake rotors: Even though you're not braking, slightly warped rotors can cause vibrations while driving at speed.
B) Sticking calipers: If a brake caliper is sticking, it could create a drag that results in vibration.
6. Engine or Transmission Problems:
A) Engine misfires: If the engine isn't firing smoothly, it can cause vibrations.
B) Transmission issues: If the transmission isn't shifting properly or there’s an issue with the torque converter, this could also cause vibrations.
If the vibration persists, it’s best to have a mechanic inspect your vehicle to determine the exact cause. Try all the DIY options like tire pressure and tire & rotor wear inspections first, places like Goodyear and Firestone offer 3yr/lifetime wheel alignment plans for under $200.
