You can Select Your Vehicle to check if 51621-TY4-A02 fits your vehicle.

If the shocks or coil springs exhibit the telltale signs of wear (leaking fluid, loss of damping capability, chipped, sagging or cracked coilsprings) explore all options before beginning any work. The shock absorbers or coil springs are not serviceable individually and must be replaced if a problem develops. However, complete assemblies may be available on an exchange basis, which eliminates much time and work. Whichever route you choose to take, check on the cost and availability of parts before disassembling your vehicle. Remove the shock absorber/coil spring assembly. Mount the shock/coil spring assembly in a vise. Line the vise jaws with wood or rags to prevent damage to the unit and don't lighten the vise excessively. Following the tool manufacturer's instructions, install the spring compressor (which can be obtained at most auto parts stores or equipment yards on a daily rental basis) on the spring and compress it sufficiently to relieve all pressure from the upper spring seat. This can be verified by wiggling the spring. Note the orientation of the upper mount in relation to the lower mounting eye. Make a sketch or some matchmarks to help you get the mount positioned properly when reinstalling it. Hold the shock damper rod with an Allen wrench, and unscrew the retaining nut with a box-end wrench. Disassemble the parts from the damper, taking care to lay the parts out in the exact order in which they are removed. Reassembly is the reverse of removal, noting the following points: Carefully place the spring onto the shock absorber body, with the end of the spring resting in the lowest part of the seat. Use a new self-locking nut, then lighten the nut. Before releasing the spring compressor, make sure the upper mount is oriented as it was before removal. After removing the spring compressor tool, the unit is ready for installation.

Place it securely on jackstands.

Raise the lower control arm with a floor jack to simulate normal ride height, then tighten the damper fork pinch bolt and damper fork-to-lower control arm bolt nut.
