Step 11:
Remove the top strut shaft nut with a 24mm socket.

Step 12:
Remove the strut from the car.

Step 13:
Moving to the rear of the car, support the rear end with a jack.

Step 14:
Pop the trunk and remove the carpet.

Step 15:
Remove the rear plastic trim covering the trunk striker.

Step 16:
Remove both carpeted trunk panels on each side.

Step 17:
Loosen and remove the upper shock bushings from both sides.

Lower the jack and loosen the bottom shock hardware. You will need a 15mm open end wrench for the bolt and an 18mm socket for the nut.

Remove the shock from the car.


Step 1:
Next using a grinder carefully grind down the outer diameter of the dust cover support from the top side of the strut. Be careful to not grind into the body of the strut.

Step 2:
Once the cover is even with the body you will be able to slide the coil over tube over the top of the strut.

Step 3:
Next thread the adjuster nut onto the coil over tube with the smooth part of nut facing upwards.

Step 4:
Install the spring onto the coil over tube so that it rests on top of the adjuster nut.

Step 5:
Now place the spring support top on top of the coil spring.

Step 6:
Place one thin washer on top of the spring support top, then a bearing and one more thin washer on top of that.

Step 7:
Lastly place the bearing cover on top of the assembly.

Step 8:
Next guide the strut assembly with coil over assembly into the strut tower (make sure you re-install the stepped 7/8” spacer onto the top of the strut bolt, this comes with your caster camber plate) and secure with the top nut to hold it in place.

Step 9:
Now you can line up the strut mount with the spindle and tighten all your bolts.

Step 10:
Repeat the above steps on the other side.

Step 11:
To adjust the ride height jack up the front of the vehicle and rotate the spring clockwise to go higher or counter clockwise to lower the car.
