Why is my Toyota Camry shaking at high speeds?

Problem: Shaking at High Speeds in a Toyota Camry (2018-present)

Tools Required

• Tire pressure gauge
• Floor jack and jack stands
• Lug wrench
• Torque wrench
• Wheel balancer (if available)
• Alignment machine (if available)
• Basic hand tools (ratchet set, sockets, wrenches)
• Inspection mirror and flashlight

Repair Instructions

Step 1: Check Tire Pressure

1. Use a tire pressure gauge to check the pressure in all four tires.
2. Inflate tires to the manufacturer's recommended pressure as indicated on the driver’s side door jamb.

Step 2: Inspect Tires

1. Visually inspect each tire for:
   • Uneven wear patterns (cupping, bald spots).
   • Sidewall bulges or punctures.
   • Cracks or cuts.
2. If any damage is found, replace the tire.

Step 3: Balance the Wheels

1. Remove the wheels using a lug wrench.
2. Mount the wheel on a wheel balancer.
3. Follow the machine’s instructions to balance the wheel. Add weights as necessary.
4. Reinstall the balanced wheel and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs).

Step 4: Check Wheel Alignment

1. If you have access to an alignment machine, perform a four-wheel alignment.
2. Adjust camber, caster, and toe angles to meet manufacturer specifications.
3. If you do not have access, take the vehicle to a professional alignment shop.

Step 5: Inspect Suspension Components

1. Raise the vehicle using a floor jack and secure it with jack stands.
2. Inspect the following for wear or damage:
   • Tie Rods: Check for play by moving them back and forth.
   • Ball Joints: Check for excessive movement.
   • Control Arms: Look for cracking or bending.
3. Replace any worn or damaged components.

Step 6: Check Brake Rotors

1. Inspect brake rotors for warpage:
   • Remove the front wheels.
   • Use a dial indicator to measure the runout of the rotor.
   • If the rotor is warped beyond specifications, consider resurfacing or replacing it.
2. Reassemble the brake components and wheel.

Final Steps

1. After performing repairs, take the vehicle for a test drive to confirm that the shaking has been resolved.
2. Monitor the vehicle for any recurring symptoms.

By following these steps, you should be able to diagnose and repair the shaking issue in your Toyota Camry effectively. If the problem persists after these checks, consider consulting a professional technician for further diagnosis.
