If the struts or coil springs exhibit signs of wear like fluid leakage, deterioration of ability to damp, or if the physical condition is compromised through chipped or cracked then before beginning with any work, one should consult as strut/shock absorber assemblies are non-repairable if there are issues with it. Ordinary strut assemblies with springs may also be obtained on an exchange basis with a view to easing the process; it is therefore advisable to establish the cost and availability of the parts beforehand. It is dangerous to disassemble a strut, sometimes body harm can occur; utilize a high-quality spring compressor, read the user instructions thoroughly. After replacing the old coil spring with the new one within the strut assembly, put the old one in a secure place. When disassembling, it is necessary to initially unbolt the strut and spring assembly and after that fasten the strut and spring on a wooden plank with rags to avoid damaging them, though should not apply excessive force. Screw the spring compressor to the standards as recommended by the manufacturer and tighten the spring until the pressure is lifted out from the upper spring seat that can be ascertained by moving the spring. Subsequently, use an Allen wrench to unlock the piston rod nut and then unscrew the upper supporting bracket of suspension and examine the bearing to see if it can run smoothly, and if not, the entire bearing should be replaced. Loosen the suspension support bolt and look at the rubber part to see if there is any signs of separation and replace them if there has been. Release the lower end of the spring and pull the spring seat along with the upper insulator off the piston rod; it is important to inspect the rubber spring seat and if it is damaged then replace it. Pick the compressed spring from the assembly gently and put it aside, being cautious and avoiding contact with the ends of the spring with body parts. Slide the dust boot off the piston rod and determine if the lower insulator is worn out and needs to be replaced. For reassembly, if fitting new lower insulator, align it in the right position and further insert the damper rod and place the dust boot in its maximum length. Put the coil spring to the lower insulator with the end seated in the recessed portion of the insulator. Applying the mark or the arrow, you have to fix the upper insulator and spring seat in a way that their arrows are out of phase. Lastly, screw on and fix the dust seal and suspension support on the piston rod the torque the nut as per the recommended torque, replace the strut or shock absorber along with the coil spring.
