You can Select Your Vehicle to check if 5151983AA fits your vehicle.

Some signs of wear include leaking fluid, loss of damping capability, and chipped, sagging, or cracked coil springs.

Install the shock absorber/coil spring assembly.

The lower mount of the shock absorber should be greased with white lithium grease for easier installation and to prolong the life of the lower shock bushing.

Remove the shock through the bottom of the spring and inspect all parts for damage. Install the parts on the new shock in the correct order. Install the washer and damper shaft nut, tightening it while holding the damper shaft with a wrench.

The shock absorber lower mounting nut and bolt should be removed to take out the shock unit.

To reassemble the strut and spring assembly, you need to extend the damper rod and install the rubber bumper. Put the dust boot onto the damper and carefully place the coil spring onto the damper, aligning it with the reference marks made during disassembly. Install the upper spring isolator and seat, followed by the upper mount, and tighten the nut on the damper shaft. Loosen the coil spring compressor until the top coil is properly seated against the upper spring seat and upper mount. Finally, remove the tool from the coil spring and install the strut/spring assembly.
