  Q: How do you disassemble the strut and spring assembly on a Toyota Sienna?

  A: To disassemble the Shock Absorber and Coil Springs, begin by removing it from the vehicle and mounting it in a vise. Use a spring compressor to relieve pressure from the upper spring seat, ensuring it wiggles freely. Loosen the damper shaft nut and remove the nut and suspension support, inspecting the bearing for smooth operation and the rubber portion for any signs of damage. Take off the upper spring seat and insulator, then carefully lift the compressed spring and set it aside. Slide the rubber bumper off the damper shaft and check the lower insulator for wear. When reassembling, if replacing the lower insulator, position it with the dropped portion seated in the lowest part of the seat and install the rubber bumper. Carefully place the coil spring onto the lower insulator, aligning the flats on the spring seat with those on the damper shaft. Align the markings on the spring upper seat and upper insulator, ensuring the arrow on the spring seat faces the lower bracket. Install the dust seal and suspension support onto the damper shaft, tighten the nut to the specified torque, and remove the spring compressor tool. Finally, install the strut spring assembly back into the vehicle.

  Q: How do you remove and inspect the coil springs on the rear of my Toyota Sienna?

  A: To remove the rear coil springs and Shock Absorbers, start by loosening the rear wheel lug nuts and raising the rear of the vehicle. Secure it on jack stands and block the front wheels. Remove the wheels. Support the rear axle beam with floor jacks on each side. Remove the lower mounting bolt or nut from each rear shock absorber and pull the shocks from their studs. If necessary, remove the coil springs by lowering the jacks. Take note of how the bottom of the spring fits into its socket on the axle beam. Inspect the vehicle's stance and the coil springs for any damage. To install the new components, place the insulators on the top of the coil springs and insert the bottom of the springs into their sockets on the rear axle beam. Raise the jacks until the springs and insulators fit securely into the body. Secure the lower shock absorber eyes with mounting bolts. Install the wheels and lug nuts. Raise the jacks, remove the jack stands, and lower the vehicle. Finally, tighten the lug nuts.
