Nissan 54010-0W001 Front Spring

If the struts or coil springs exhibit signs of wear such as leaking fluid, loss of damping capability, chipped, sagging or cracked coil springs, explore all options before beginning any work. The strut shock absorber assemblies are not serviceable and must be replaced if a problem develops. However, strut assemblies complete with springs may be available on an exchange basis, which eliminates much time and work. Check on the cost and availability of parts before disassembling your vehicle. Remove the strut and spring assembly. Mount the strut assembly in a vise. Line the vise jaws with wood or rags to prevent damage to the unit and don't tighten the vise excessively. Install the spring compressor on the spring and compress it sufficiently to relieve all pressure from the upper spring seat. This can be verified by wiggling the spring. Remove the piston rod nut. Remove the upper mount. Inspect the bearing in the mount for smooth operation. If it does not turn smoothly, replace it. Check the rubber portion of the mount for cracking and general deterioration. If there is any separation of the rubber, replace it. Lift the springseat and upper insulator from the piston rod. Check the rubber springseat for cracking and hardness, replacing it if necessary. Carefully lift the compressed spring from the assembly and set it in a safe place. Slide the dust boot off the piston rod. Check the lower insulator for wear, cracking and hardness and replace it if necessary. If the lower insulator is being replaced, set it into position with the dropped portion seated in the lowest part of the seat. Extend the damper rod to its full length and install the dust boot. Carefully place the coil spring onto the lower insulator, with the end of the spring resting in the lowest part of the insulator. Install the upper insulator and the spring seat. Make sure the cutout on the spring seat is facing in, away from the strut-to-knuckle flange. Install the dust seal and upper mount to the piston rod. Install a new piston rod nut and tighten it to the torque. Install the strut assembly.

The coil springs can be removed.
