This installation should be performed by a trained professional. The installation requires lowering of the rear cradle from the vehicle for spring removal and reinstallation.
Tools Required for this Installation
- Hydraulic jack, jack stands, torque wrench (4 post lift or alignment rack preferable)
- Coil spring compressor (most major auto parts chains can rent these out)
- The following sockets or wrenches: 10mm, 13mm, 15mm, 16mm, 18mm, 21mm
INSTALLATION OF HOTCHKIS FRONT COIL SPRINGS
1) Secure the rear wheels with blocks and jack the front up until the front wheels are off the ground. Support the front of the vehicle with jack stands on the frame.
2) Remove the front wheels using a 21mm socket.
3) Loosen the upper control arm ball joint bolt (do not remove yet). Apply some WD-40 or similar penetrating lubricant to soak the tapered stud. Use a hammer to smack the control arm flat spot in order to break loose the ball joint stud. Once loose, you may remove the ball joint nut. Do not let the steering knuckle hang by the brake line. Use a wire or string to hold the knuckle up. Retain hardware for reinstallation.
4) Loosen and remove the lower shock bolt using a 18mm socket or wrench. Retain hardware for reinstallation.
