1. Worn steering components: Check the steering linkage, including the tie rods, ball joints, and control arms, for any signs of wear or damage. Worn components can cause the front end to shake or wobble when driving at low speeds.
2. Alignment issues: A misaligned front end can also lead to shaking or vibration. Have your vehicle's alignment checked to ensure that the wheels are pointing straight ahead. Misalignment can also result in uneven tire wear.
3. Loose or damaged wheel bearings: Worn wheel bearings can lead to excessive play in the front wheels, which can cause the front end to shake. To check the wheel bearings, lift the vehicle and check for any looseness or noise when rotating the wheels.
4. Tire problems: Uneven tire wear, low tire pressure, or damaged tires can cause shaking or vibration at low speeds. Check the condition of your tires and make sure that they are properly inflated to the recommended pressure.
5. Driveshaft issues: A worn or damaged driveshaft can cause the front end to shake or vibrate. Inspect the driveshaft for any signs of damage and check the mounting bolts to ensure that they are tight.
If you are experiencing front-end shaking or vibration in your 1997 Ford Expedition, it's important to have the issue diagnosed and repaired by a qualified mechanic to ensure safety and prevent further damage.
