If the shock absorber and coil spring assemblies require replacement, simply put, new complete assemblies could be installed for efficiency, but if one wishes to replace shocks or springs, one would have to disassemble the assemblies. However, complete assemblies may be only slightly more expensive than the individual part therefore before making the final decision compare local costs. First immobilise the front wheel nut, lift the car securely on jack stands and finally, withdraw the front wheels. From the underneath side of the car you remove the nut and bolt that fixes the lower end of the shock absorber to the lower control arm. Subsequently, there are three nuts turning off, the nuts at considerable end of the linkage for the shock to the frame bracket with no touch on the damper rod nut. In the front suspension system, you have to first reduce the shock absorber and coil spring assembly and examine carefully the shock for leakage and dents and if the coil spring has any chips or cracks. If any of the respective components are worn or damaged then the same should be replaced with fresh ones. When reusing old shock absorbers, use the assembly to clamp in a bench vise with soft jaws and should not be over-tightened. Proceed to accommodate the spring compressor in to compress a spring in a way that will allow it to wobbled. Loosen the damper rod with a wrench and unscrew the damper rod nut next, then remove the upper retainer, upper cushion, and suspension support; finally take off the compressed spring assembly. Break the lower retainers and cushion by releasing all the clips that hold it, check that all cushions are not damage and if so replace them. Disassemble in a reverse manner, starting from the removal of the shock absorber; ensure the coil spring is seated properly before loosening the damper rod nut to the recommended torque value then you release the tension in the coil spring. Last of all, place the assembly in the reverse of its dismantling putting in all the bolts and screws in their appropriate tightness.
