Kia 546301U413 Front Suspension-Coil Spring

If the shocks or coil springs show signs of wear such as leaking fluid, loss of damping capability, or physical damage like chips, sagging, or cracks, consider all options before starting any work. The shock absorbers or coil springs cannot be serviced individually and must be replaced if issues arise, although complete assemblies may be available on an exchange basis, saving time and effort. Before disassembling the vehicle, check the cost and availability of parts. For removal, if working on the left-side shock absorber, first remove the battery and junction block, and on 2006 and earlier models, the cruise control actuator. Loosen the front wheel lug nuts, raise the vehicle securely on jackstands, and remove the front wheels. Unbolt the brake hose bracket, then remove the upper control arm. Next, take out the shock absorber lower mounting bolt and, while supporting the shock absorber assembly, remove the upper mounting nuts before taking out the assembly, which may require prying down on the lower control arm for clearance. Although it is possible to replace shocks or springs individually, this typically requires a qualified repair shop and can be costly, so compare the expense of replacing complete assemblies yourself versus individual components. For installation, reverse the removal steps, ensuring to tighten the upper and lower fasteners to the specified torque values and securely fasten the brake hose bracket mounting bolt. Tighten the upper control arm pivot bolts and the shock absorber lower mounting bolt with the vehicle at normal ride height, which can be achieved by bouncing the vehicle after assembly or simulating the height with a floor jack. Finally, tighten the lug nuts to the specified torque.

Support the lower control arm with a floor jack placed under the area of the coil spring, then unbolt and disconnect the lower control arm from the rear knuckle.
