To remove the struts, first, check for signs of wear such as leaking fluid or loss of dampening capability. Consider options like rebuilt or new strut assemblies that may be available on an exchange basis. Once ready, remove the strut and spring assembly and mount it in a vise, cushioning the vise jaws with rags or blocks of wood. Use a spring compressor to relieve pressure from the spring seat, following the tool manufacturer's instructions. Loosen the damper shaft nut while holding the shaft stationary with the proper tool. Lift off the bearing cap, upper spring seat, and upper insulator, inspecting the bearing in the spring seat for smooth operation and replacing if necessary. Carefully remove the compressed spring assembly and set it aside. For installation, assemble the new strut starting with the lower spring insulator and spring, followed by the upper spring insulator, spring seat, and bearing cap. Position the spring seal and bearing cap with the flats facing the steering knuckle flange. Install and tighten the damper shaft nut to the specified torque. Finally, install the strut and spring assembly and have the front-end alignment checked and adjusted if needed.
