3. Tighten any loose bolts or nuts found during inspection to the manufacturer’s specified torque values.

3. Replace Worn or Damaged Parts

Sub-steps:
1. If any components are found to be damaged (e.g., shock absorbers, bushings), remove them using a socket set.
2. Install new parts according to manufacturer specifications, ensuring all bolts are torqued correctly.
3. For bushings, use a pry bar to remove old ones and press in new bushings using a suitable tool.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall any components that were removed for inspection, ensuring all fasteners are secure.
2. Carefully lower the vehicle back to the ground.
3. Perform a final check to ensure everything is tightened and in place.
