my Toyota RAV4 Fifth Generation (2019-present) feels bumpy and unstable while driving, what could be...

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat, level surface and engage the parking brake.
• Disconnect the battery if working on electronic steering components.

2. Tire Inspection and Replacement

1. Check Tire Pressure

   • Use a tire pressure gauge to measure the pressure and inflate to the recommended PSI.

2. Inspect Tire Tread

   • Use a tread depth gauge to measure tread depth; replace tires if below the minimum specification.

3. Replace Tires (if necessary)

   • Use a jack to lift the vehicle and remove the lug nuts with a socket set.
   • Remove the old tire and mount the new tire, tightening the lug nuts to the manufacturer's torque specification (typically around 80-100 ft-lbs).
   • Lower the vehicle and perform the same for all affected tires.

3. Suspension Inspection and Repair

1. Inspect Suspension Components

   • Visually check for leaks in shocks or struts; replace if necessary.

2. Replace Worn Components

   • If shocks or struts are worn:
     • Remove the old components using a socket set and replace with new parts.
     • Torque to manufacturer's specifications.

4. Wheel Alignment

1. Perform Wheel Alignment
   • Use a wheel alignment machine to adjust the angles of the wheels to the manufacturer’s specifications.
   • Test drive the vehicle to ensure handling is improved.

5. Steering Component Inspection

1. Check Steering Components
   • Inspect tie rods and ball joints for wear.
   • Replace any worn components as necessary, following similar steps to suspension component replacement.
