Well.. I got my H-techs last week and did the install this past Friday night. It would've been fairly easy except for the two lower shock bolts in the rear!!!!
But... we got it after some time. More on that later.... here's my walkthrough....
First... a shot of the springs.....
Front strut spring swap......
1.) I decided to do the front spring swap first. Raise the vehicle off the ground and support it with jack stands. The stand must NOT be under the control arm... as you need this to drop so that you can get the strut out.
2.) Remove the front wheel.
3.) Once the wheel is removed... you will clearly see the front strut assembly.
4.) Remove the brake line from the strut assembly.....
5.) Next, remove the other line (I think it is the ABS sensor line) from the strut bracket.
6.) Once both of these lines are loose from the strut... you will need to locate the two attachment bolts on the lower end of the strut. The top bolt can be seen in the above photos. The lower one is about 1" below it. The bottom bolt is just that... a bolt and nut assembly. The upper bolt is an eccentric assembly that is used to adjust the camber of the front wheel. MARK THE UPPER BOLT LOCATION with respect to the strut assembly BEFORE loosening the nut and removing the bolt.
7.) Once the two lower mount bolts have been removed... you can loosen and remove the three retainer bolts from the top hat. This is located under the hood (on top of the shock tower). You can seen them on either side in this photo....
I recommend loosening all three first.... to where they can be removed by hand. Then.. grab the strut and remove the nuts... the strut will fall out at this point if you aren't holding it.
8.) Here is what the factory strut looks like....
9.) Remove the shaft nut cover at this point.
10.) *** BE VERY CAREFUL and TAKE YOUR TIME
.... A COMPRESSED SPRING CAN SERIOUSLY INJURE or KILL YOU IF IT GETS LOOSE **** Using spring compressors (you can rent them from Autozone), compress the springs until the pressure is off of the top spring pad. When this happens... use a pass through socket to remove the nut (you will need to hold the shaft with an allen key inserted through it).
11.) Remove the nut, the top hat, the top spring washer, the top spring plate, the spring, and the shaft cover.
12.) Decompress the stock spring VERY CAREFULLY and set it aside.
13.) Here is a picture of the completely disassembled front strut.... for reference. The strut body is on the right and the other pieces are in order that they go on (towards the left)
14.) Reassemble the strut vertically (I put mine in a vice) by placing the new H-tech spring in the lower pocket, the shaft cover on the shaft, the top spring plate on, and the top plate washer. Have a friend pull down on the top spring plate (about 1/2") and then drop on the tophat and start the nut.
15.) Tighten the nut fully... while holding the shaft still (otherwise it will spin).
16.) Here is the completed assembly with the H-tech installed.
17.) Reinstall the strut back into the car in the reverse order you removed it. Top hat nuts, lower strut bolts, ABS line, and Brake line. Here is the strut back in the car....for reference.... Be sure to try and re-allign the top strut bolt to it's original orientation. This will ensure that the camber is as close as possible to factory...
18.) Reinstall the wheel and then do the other side.
