When the front suspension struts display any wear conditions (such as leaking fluid, damping loss, or sagging and cracked
Coil Springs) then they can be disassembled and overhauled accordingly and faulty struts need replacement whereas springs and other components can be replaced individually. Both sides have to be replaced to ensure that the balance between the properties is maintained. After the strut is out of the car, clear off all the foreign matter and you should fit it in the vise. Install the coil spring compressor tools in place and push the spring up until all the tension is out of the upper mount. Using an Allen key, loose the strut piston rod and using a box-end wrench, loosen the retaining nut of the thrust bearing then withdraw the top mounting, thrust bearing, upper spring seat and spring and the boot and bump stop. In case a new spring is to be inserted, the old spring must be removed carefully out of the compressor; in case of a reuse, the spring may be left under compression. Once the strut assembly is disassembled, inspect every part of the assembly in terms of wear and damage, and also ensure the bearing is running smoothly and that the parts are in place accordingly. Look at the strut to see whether it is leaking fluid, examine the piston rod to see whether it is pitted and examine the strut body whether it has been damaged. Check the functioning of the strut by operating the piston in both full and short strokes and make sure the resistance is smooth and continuous; rough or irregular resistance denotes that it requires replacement. Reassembly consists of repeating the dismantling process, making sure the coil springs are fitted with the paint mark at the bottom, that the coil spring ends are carefully placed in the upper and lower seats, before the release of the compressor, and to confirm that the bearing is properly fitted to the piston rod seat, and the thrust bearing retaining nut is tightened to the required torque.
