- Check control arms, bushings, and sway bar links for damage or excessive play.
Replace Worn Parts:
- If any component is damaged, remove it using a socket set and replace with a new part.
- Ensure to torque bolts to manufacturer specifications (typically 40-70 ft-lbs for suspension components, but check specific values).

3. Shock Absorber Replacement

Remove Old Shock Absorbers:
- Disconnect the top and bottom bolts of the shock absorber using a socket set.
- Remove the old shock absorber from its mount.
Install New Shock Absorbers:
- Position the new shock absorber in place and secure it with the bolts.
