1. Worn or Damaged Wheel Bearings: This is a high-probability cause. When you accelerate and turn, you're putting significant stress on the wheel bearings. Worn bearings create friction, leading to squeaking noises. They might also make a grinding or rumbling sound at higher speeds. This needs professional attention ASAP as a failed bearing can lead to a complete wheel seizure.
2. Worn CV Joints (Constant Velocity Joints): These joints allow the wheels to turn while transmitting power. Worn CV joints can squeak, especially under load (acceleration and turning). You might also notice clicking or popping sounds, especially when turning sharply at low speeds.
3. Brake Caliper Issues: A sticking or slightly seized brake caliper can cause a squealing noise, particularly when turning. The caliper piston might be binding, causing friction and heat, leading to the squeak.
4. Suspension Components: While less likely to squeak specifically during acceleration and turning, worn ball joints, tie rod ends, or bushings can contribute to noises, particularly if there's a significant amount of play in these components.
5. Low Brake Pad Material: While usually a grinding noise, extremely low brake pads might squeak in unusual ways depending on their composition and the wear pattern.
Troubleshooting Steps:
1. Visual Inspection: Start by carefully inspecting your front wheels and brakes. Look for anything obvious:
* Brake Pads: Check the thickness of your brake pads. Replace them if they're worn down.
* Brake Rotors: Look for excessive rust, scoring, or warping.
* CV Boots: Inspect the rubber boots surrounding the CV joints for cracks or tears. If damaged, the grease inside will leak, leading to premature wear and squeaking.
* Suspension Components: Look for obvious damage or looseness in the ball joints, tie rod ends, and other suspension components.
2. Jack Up the Car (Safely): Use jack stands to securely support the vehicle. Rotate each wheel individually, listening carefully for any squeaking or grinding sounds. Try to wiggle the wheel in and out – excessive play indicates a worn bearing or other suspension component.
3. Professional Diagnosis: If you can't pinpoint the problem after a visual inspection and some simple checks, take your Intrepid to a qualified mechanic. They have the tools and expertise to diagnose the issue accurately and perform the necessary repairs.
Safety Note: Driving with worn wheel bearings or CV joints is dangerous. Ignoring these issues could lead to a loss of control of your vehicle. It's best to have the problem addressed as soon as possible.
