why is my Toyota Tacoma N300 (2016-Present) making a grinding noise

Solution

1. Preparation

• Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, brake cleaner, mechanic's stethoscope.
• Safety Warnings: Ensure the vehicle is on a level surface and secure with wheel chocks before lifting.

2. Inspect and Replace Brake Components

• Check brake pads and rotors for wear.
  • If worn, remove the wheel using a socket set.
  • Inspect brake pads for thickness; replace if less than 3mm.
  • Inspect rotors for scoring or warping; replace if damaged.
• Parts Required: Brake pads, rotors (if necessary).
• Reassemble the wheel and torque to manufacturer specifications (typically 75-85 ft-lbs).

3. Transmission Fluid Check and Replacement (if necessary)

• Remove the transmission fill plug and check fluid level.
• If low, add the appropriate transmission fluid (refer to owner’s manual for specifications).
• If fluid is dirty or burnt, drain and replace the fluid:
  • Remove the drain plug and allow fluid to completely drain.
  • Replace with new fluid, ensuring to follow the manufacturer's specifications for type and amount.
• Reinstall drain plug and torque to specification.

4. Inspect and Replace Driveshaft or Differential Components

• Check the driveshaft for any signs of damage or excessive play.
  • If damaged, remove and replace the driveshaft.
• Inspect the differential for noise or play.
  • If there’s an issue, consider opening the differential for inspection or replacement of gears/bearings.

5. Wheel Bearing Inspection and Replacement

• Jack up the vehicle, support it with jack stands, and remove the wheel.
• Check for wheel bearing play by rocking the wheel in and out.
• If excessive play is noted, remove the hub assembly and replace the wheel bearings as needed:
  • Use a bearing puller for removal and a press for installation.
• Reassemble and torque to specifications.
