INSTALLATION OF HOTCHKIS FRONT COIL SPRINGS
Securely block the rear wheels of the vehicle. Use a jack to lift up the front of the vehicle and use jack stands to support it. Remove the front wheels.
Use a 14mm wrench and 6mm Allen wrench to loosen and remove the hardware holding the sway bar end links to the front struts. Retain the hardware for later re-installation.
Use a 13mm and 10mm socket or wrench to loosen and remove the bolts holding the brake lines to the strut. Retain the hardware for later re-installation.
Use a 21mm and 22mm socket or wrench to loosen and remove the two bolts holding the base of the strut to the spindle. Use a 12mm socket or wrench to loosen and remove the nuts retaining the top of the strut. The strut will now be free and can drop out of the vehicle. Use caution to avoid dropping the strut, as this could damage the strut or the vehicle.
Place one of the struts into the coil spring compressor and collapse the spring until the upper strut plate is no longer under tension. Remove the plastic dust cover on the top of the strut. Use a 19mm socket and a 6mm Allen wrench to remove the retaining nut at the top of the strut. Retain the hardware for later Re-installation.
Remove the upper strut plate, upper spring seat, rubber dust shield / spring isolator, and the stock bump stop from the end of the strut. This should leave the stock spring completely exposed. Slowly release the compression on the spring and remove the stock spring.
Slide the new bump stop over the end of the strut with the narrow end facing towards the bottom. It should rest just below the “shelf” on the end of the strut shaft. Place the new Hotchkis spring over the strut. Make certain to line up the bottom of the coil, or tail, with the perch in the lower spring seat and isolator pad.
Observe the stamped arrow on the upper spring seat before reassembly. The arrow is highlighted in the picture below.
Replace the rubber spring isolator / dust cover on the spring. Place the upper spring seat on top of the coil and align the coil assembly. The stamped arrow on the upper spring seat should be pointed between the two flanges at the bottom of the strut.
