Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Gather required tools: jack, jack stands, socket set, torque wrench, and possibly a spring compressor if springs need to be replaced.

2. Tire Inspection and Replacement

• Sub-steps:
  1. Remove the lug nuts using a socket set and take off the wheels.
  2. Inspect tires for any signs of uneven wear or damage; replace if necessary.
  3. Check and adjust tire pressure according to the manufacturer's specifications.
  4. Reinstall wheels and torque lug nuts to the manufacturer’s specified torque value.

3. Suspension Component Replacement

• Sub-steps:
  1. Jack up the vehicle and support it with jack stands.
  2. Remove the wheel to access the suspension components.
  3. Inspect and replace shock absorbers or struts if they show signs of leakage or wear.
     • Disconnect the top and bottom mounting bolts for shocks/struts.
     • Remove the shock/strut assembly.
     • Install the new shock/strut, ensuring all bolts are torqued to manufacturer specifications.
  4. Inspect and replace any worn springs, using a spring compressor if necessary for safe removal and installation.
