Sub-steps:
1. Start with the exhaust system. Check all hangers and brackets; tighten any loose bolts or replace damaged hangers.
2. Inspect the heat shield; if loose, tighten or replace as necessary.
3. Move to the suspension components (control arms, sway bar links). Use a torque wrench to ensure all bolts are tightened to manufacturer specifications (check your service manual for torque values).

3. Repair or Replace Damaged Parts

Sub-steps:
1. If any suspension components are worn (e.g., bushings, shock absorbers), replace them with OEM parts.
2. For a damaged exhaust system, replace the affected section and ensure proper fitment with all necessary clamps and gaskets.
