Likely culprits:
* Sway bar bushings/links: These rubber bushings connect the sway bar to the control arms. Worn bushings are a very common cause of squeaks, especially over bumps. Inspect them for cracks or excessive wear. They are relatively inexpensive to replace.
* Ball joints: These connect the control arms to the steering knuckles. A worn ball joint can squeak, especially when turning. Excessive play in the ball joint indicates it needs replacing.
* Tie rod ends: Similar to ball joints, these connect the steering rack to the steering knuckles. Worn tie rod ends can squeak and also affect steering.
* Rack and pinion boots: Tears in the boots surrounding the rack and pinion steering can allow grease to leak out, leading to squeaking and eventual damage to the steering system.
* Suspension components: Worn struts, shocks, or springs can create noises, though these are more likely to be clunks or thuds than high-pitched squeaks.
* Brake components: While less likely to be a constant squeak, worn brake pads or caliper issues can produce noises.
* Body mounts: These isolate the body from the frame. Worn mounts can allow squeaking.
Troubleshooting steps:
1. Reproduce the squeak: Drive the Escape over various surfaces (bumps, turns) to pinpoint when the squeak occurs. This helps narrow down the potential source.
2. Visual inspection: Carefully examine the front suspension components mentioned above. Look for cracks, worn rubber, missing grease, or any obvious damage. Jacking up the front end will make this easier but be sure to use jack stands for safety!
3. Listen closely: While someone else moves the suspension (by gently rocking the vehicle), listen carefully to pinpoint the location of the squeak.
4. Test the steering: Turn the steering wheel back and forth slowly, listening for squeaks.
5. Brake test: Gently apply the brakes to see if it's related.
If you're not comfortable working on your car yourself: Take it to a mechanic for diagnosis and repair. Describing the squeak (high-pitched, low-pitched, only when turning, etc.) will help them pinpoint the problem faster. Don't delay addressing this, as a small squeak can indicate a larger problem developing.
