Step 10: Compress your new spring using a spring compressor.
Step 11: Place the bottom puck into the lower control arm and the top puck into the spring. Use a pry bar to pry down the knuckle and place the new spring into position.
Step 12: Remove the spring compressors from the spring.
Step 13: Place the new shock in position, with the round indents on the top mount facing towards the inside of the vehicle.
Step 14: Place the bottom shock bolt in position and tighten with nut.
Step 15: Place a jack under the control arm and raise it until the top shock mount reaches the mounting holes.
