Use a socket set to remove the bolts securing the bushings.
Inspect the bushings for cracks or signs of wear; replace if necessary.
Install new bushings and torque to manufacturer specifications.

4. Examine Shock Absorbers/Struts

Check the condition of shock absorbers or struts for leaks or physical damage.
If replacement is necessary, use a socket set to remove the top and bottom mounting bolts.
Install new shock absorbers or struts, ensuring proper alignment and torque specifications are followed.
