Solution

1. Preparation

Gather tools including a jack, jack stands, lug wrench, and torque wrench.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Components (if applicable)

Remove Wheel:
- Use a lug wrench to loosen lug nuts before lifting the vehicle with a jack.
- Remove the lug nuts completely and take off the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if below 3mm.
- Inspect rotors for scoring or warping; replace if damaged.
Replace Brake Pads and Rotors:
- Remove caliper bolts and slide the caliper off.
- Replace pads and install new rotors if needed.
- Reassemble caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Wheel Bearings (if applicable)

Remove Wheel and Brake Assembly:
- Follow the same procedure as above to remove the wheel.
- Remove the brake caliper and rotor.
Check Wheel Bearings:
- Use a dial indicator to measure play; replace bearings if excessive.
- Press out the old bearing and press in the new bearing.
Reassemble:
- Reinstall rotor, caliper, and wheel. Torque all bolts to specifications.

4. Inspect Transmission Fluid (if applicable)

Check Fluid Level:
- Locate the transmission dipstick and pull it out.
- Wipe clean, reinsert, and check fluid level; add fluid if low.
Change Transmission Fluid:
- Drain old fluid from the transmission pan.
- Replace the filter and refill with manufacturer-recommended fluid.
