Here are some potential causes of the shaking and vibration you are experiencing in your 1999 Toyota Camry:
1. Wheel Alignment: Improper wheel alignment can cause the car to shake and vibrate, particularly at higher speeds. It's important to ensure that the wheels are properly aligned as recommended by Toyota.
2. Tire Balance: Unbalanced tires can cause shaking and vibration, especially at certain speeds. Get the tires checked for proper balancing, and have them balanced if necessary.
3. Worn Steering Components: Over time, steering components such as tie rods, ball joints, and steering linkage can become worn or damaged, leading to vibration and shaking. Inspect these components for wear or play, and replace them if needed.
4. Warped Brake Rotors: If the brake rotors are warped or uneven, it can cause the front end to shake and vibrate when applying the brakes. Have the rotors checked and resurfaced or replaced if necessary.
5. Suspension Problems: Worn or damaged suspension components, such as shock absorbers, struts, control arms, and bushings, can contribute to shaking and vibration. Inspect these components for any issues and replace them as needed.
6. Driveshaft or CV Joints: If the driveshaft or constant velocity (CV) joints are damaged or have excessive play, it can cause vibration. Check these components for any issues and have them repaired or replaced if necessary.
7. Engine Mounts: If the engine mounts are worn or damaged, it can allow vibrations from the engine to be felt inside the vehicle. Inspect the engine mounts and have them replaced if needed.
8. Wheel Bearings: Worn or damaged wheel bearings can also cause vibration and shaking. Listen for any unusual noises coming from the wheels and inspect the bearings for any play or damage. Replace them if necessary.
It's important to address these issues as soon as possible, not only to prevent further damage to your vehicle but also to ensure your safety and the safety of others on the road. If the shaking and vibration persist after inspecting and repairing these components, it's best to consult with a qualified mechanic for further diagnosis.
