If there are visible signs of strut or coil spring deterioration including leakage of the fluid, loss of a damping scheme, or physical damage, give all the options priority before beginning any work as strut/shock absorber assemblies are non-serviceable and need replacement if there is a problem. When strut assemblies contain springs, they may be obtained on exchange basis which can be convenient; therefore, it is worth comparing the cost and availability of the parts before taking the vehicle apart. To disassemble, to remove the strut and spring assembly, fix it in a wooden vise or put pieces of wood and rags in between the vise jaws and the assembly, and to not overtighten the bolts. Mount a spring compressor as per the manufacturer's procedure to free the pressing pressure from the upper spring seat that can be checked by jerking the spring. To check the bearing, unscrew the damper shaft nut and then remove the nut and suspension support After that check it and if required replace it. Inspect the rubber part of the suspension support to see that it is not disintegrating and if possible replace the part. Check the outer condition of the upper spring seat mounted on the damper shaft for presence of cracks or hardness and if it is found to be worn out, change it, followed by the removal of the upper insulator. Have the ends pointed away from your body and lift the compressed spring from the assembly carefully and put it aside. Pull the rubber bumper and slide it off the damper shaft, then inspect the lower insulator to see if it has deteriorated; if so, install a new one. In reassembly of the component, if the lower insulator is being replaced, then position the same with the dropped portion blending at the lowest point of the seat, next, insert the dampner rod and then the rubber bumper. Unscrew the spring seat and put the upper insulator followed by the spring seat aligning the flats on the damper shaft with those in the spring seat; place the coil spring on the lower insulator end fitting it into the lowest part. When the pinned holes of the upper spring seat are in aligned with the ones of the lower, fit the damper nut and tighten it to the recommended torque while the holes in the spring seats are aligned and finally, before fitting the strut/spring assembly, release the spring compressor tool.
