What should I check if my 2021 Ford Explorer has a rough ride quality?

If your 2021 Ford Explorer is experiencing a rough ride quality, there are several potential causes to investigate. Below, I will outline the symptoms, diagnostic steps, tools required, and detailed repair instructions.

Tools Required

• Tire pressure gauge
• OBD-II scanner
• Floor jack and jack stands
• Torque wrench
• Wrench and socket set
• Suspension tool kit (spring compressors, etc.)
• Measuring tape (for alignment checks)
• Rubber mallet (for bushings)

Repair Instructions

Step 1: Inspect and Inflate Tires

1. Use a tire pressure gauge to check each tire's pressure.
2. Inflate tires to the recommended PSI if they are below specification.
3. Inspect for wear: Look for signs of cupping or uneven tread wear.

Step 2: Examine Suspension Components

1. Shocks/Struts:

   • Visually inspect for oil leaks.
   • Push down on each corner of the vehicle; it should rebound no more than twice.
   • If they fail, replace shocks/struts.

2. Control Arms and Bushings:

   • Check for play in the bushings with a pry bar.
   • Replace any worn or damaged bushings.

3. Ball Joints:

   • Lift the vehicle and check for play in the ball joints.
   • If any movement is detected, replace the ball joints.

4. Sway Bar Links:

   • Inspect sway bar links for signs of wear or damage.
   • Replace as necessary.

Step 3: Perform Wheel Alignment

1. After checking and replacing any worn components, perform a wheel alignment.
2. Use an alignment machine or string alignment method to adjust camber, caster, and toe settings to manufacturer specifications.

Step 4: Test Drive

1. After completing repairs and alignment, take the vehicle for a test drive.
2. Check if the rough ride quality has improved.

Conclusion

By following these steps, you should be able to diagnose and address the rough ride quality in your 2021 Ford Explorer. If issues persist after these checks and repairs, further investigation may be needed, potentially involving the vehicle's advanced suspension systems or electronic components. If you're not comfortable performing these diagnostics or repairs, consider seeking professional assistance.
