Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Components

Jack up the vehicle and secure it with jack stands.
Remove the wheel using a socket set.
Inspect brake pads and rotors:
- Measure the thickness of the brake pads; replace if below specifications (generally 3mm).
- Check the rotor surface for grooves or scoring; replace if necessary.
Replace brake pads:
- Remove the caliper by unscrewing the mounting bolts.
- Replace the old pads with new ones, ensuring they are properly seated.
- Compress the caliper piston using a brake caliper tool before reinstalling.
Reassemble the brake system and replace the wheel.
Lower the vehicle and test the brakes by pumping the pedal to restore pressure.

3. Inspect and Repair Drivetrain Components

Check CV joints and axles for any signs of wear or damage.
- Look for grease leaks or torn boots.
Replace damaged CV joints or axles:
- Remove the wheel and disconnect the lower control arm if necessary.
- Remove the axle nut, then pull the axle out of the hub.
- Install the new axle or CV joint and secure it with the axle nut to manufacturer specifications (typically 150-180 ft-lbs).
Reassemble all components and lower the vehicle.

4. Inspect and Repair Suspension Components

Visually inspect the suspension for any worn bushings or damaged parts.
Replace any damaged suspension components:
- Use a wrench to remove and replace any worn out bushings or struts.
- Ensure all bolts are torqued to manufacturer specifications.
Reassemble the suspension and check the alignment if necessary.
