**Why Does My Car Shake When Driving? Common Causes and Solutions**

Feeling your car shake while driving can be unsettling and inconvenient. It’s important to identify the underlying cause to ensure your safety and prevent further damage. Here’s a comprehensive overview of the most common reasons why your car might be shaking and what you can do about it.

### 1. Unbalanced or Worn Tires

**Symptoms:** Vibration that increases with speed, usually felt in the steering wheel or seat.

**Cause:** Over time, tires can become unbalanced due to uneven wear or damage. This imbalance causes the tires to wobble at certain speeds, leading to shaking.

**Solution:** Have your tires professionally balanced. Regularly check for uneven wear or damage and replace worn tires as needed.

### 2. Misaligned Wheels

**Symptoms:** Steering wheel vibrates or pulls to one side, uneven tire wear.

**Cause:** Hitting potholes, curbs, or general wear can misalign your wheels, causing instability and shaking.

**Solution:** Get a wheel alignment service. Proper alignment ensures your tires contact the road evenly and reduces vibrations.

### 3. Worn Suspension Components

**Symptoms:** Shaking over bumps or uneven surfaces, poor handling.

**Cause:** Components like shocks, struts, or bushings can wear out over time, affecting ride quality and causing shaking.

**Solution:** Have a mechanic inspect your suspension system and replace worn parts.

### 4. Brake Issues

**Symptoms:** Shaking when braking, but not necessarily when driving.

**Cause:** Warped brake rotors can cause a pulsating brake pedal and shaking during braking.

**Solution:** Resurface or replace brake rotors and ensure brake pads are in good condition.

### 5. Engine or Transmission Problems

**Symptoms:** Shaking occurs at specific speeds or during acceleration.

**Cause:** Engine misfires, worn spark plugs, or transmission issues can cause vibrations.

**Solution:** Regular engine maintenance, including spark plug replacement and diagnostics, can resolve these issues.

### 6. Driveshaft or CV Joint Problems

**Symptoms:** Shaking at specific speeds, clicking noises when turning.

**Cause:** Worn or damaged driveshafts or CV joints can cause vibrations.

**Solution:** Have these components inspected and repaired or replaced as needed.
