4. Pull the shock away from the mounting points and remove it from the vehicle.

4. Install New Shocks/Struts

Front Shocks/Struts:
1. Position the new strut assembly in place of the old one.
2. Secure the top mounting bolts to the strut tower and torque to manufacturer specifications.
3. Reattach the lower bolts to the steering knuckle and torque them appropriately.
4. Reconnect the stabilizer bar link if applicable.
Rear Shocks/Struts:
1. Position the new shock in place, aligning it with the mounting points.
