Start by disconnecting the strut assembly from the top. This usually involves removing bolts located in the engine bay or trunk, depending on the vehicle model.
4. Remove the Lower Strut Bolts
Next, remove the lower strut bolts using the appropriate socket and wrench. Be cautious as the strut may be under tension.
