is this the part you're talking about? if so... i didn't do that!! ... guess i know what i'm doing tonight after work.

EDIT: also, should we or should we not reuse the small, white, circular gasket from the OEM rear shocks top mount? I didn't, but thinking about it, it may help reduce metal on metal noises.

basically you want the shock short enough to be pulling up on the suspension a little if the car is jacked up so that the spring isn't loose..

jack your car up, see if the spring will move around

this assures that their is always some sort of tension on the spring

Bingo! lol I think we may experiment with video installs also. Pictures and videos help alot. I've always been able to pick up things alot quicker seeing it done.

Pete@BC

I don't recall seeing the gasket your talking about. It won't hurt to use, but I've never personally had any issues with metal to metal contact making noise as long as it's tight.

Pete@BC

These measurements change on the shock depending on the height choosen for the vehicle. For the moment forget about all oem measurements. You want our shock to match our spring setup. Just for example, if you jacked your rear up by the diff and both wheels are off. The shock will be at full extension. If you reach in and grab the spring and it moves at all, you have no preload on it. You'll want to remove the lower bolt to the shock and raise the hub up enough to put a load on the springs. Using the shock to hold that load when fully extended. In the instructions, you'll see how the bolt hole to the lower shock shows the holes don't line up. The shock is higher than the hub. Let me know if this helps everyone.

As for this being done on a lift at a professional shop. It is much harder to do on a lift than on the ground. Atleast this preload technique. We've utilized the lift, but will have a bar stool or something to bring the car down on to create the preload and lock in place. Believe me though, on the ground is the easiest way with a jack.

Pete, I did exactly as you instructed here and in your writeup. the ride is definitely better than it was, but the rattle is MORE pronounced. only at low speeds though. this rattle, or knocking is nowhere to be found above about 25MPH, but below that, on most medium surface imperfections, will have this noise.

EDIT: just thought i'd also say that all nuts and bolts are torqued up and tight as well as all collars are tight.

have you tried having someone else drive the car while you walk next to it? may give you some sort of an idea

you could try jacking your car up and then lifting up/down on your wheels.. might be enough to make the sound, might not

Another update on my rear rattle:

As I mentioned on Saturday I broke my rear suspension down and reassembled, basically to be sure I had everything tight and together correctly from my installer. Since then, I have not had a single rattle out of my rear suspension. I did NOT height adjust anything in the rear, just broke down and reassembled.

In the front I spun it down a few and dropped about another inch, and wow is it low. I need to bring it back up about half an inch. Current ground to front fender measurement is 26.5 inches.

I'd also advise everyone (as Pete mentioned) to go ahead and preload the springs again as I noticed it made a big difference on my car as far as "bouncy" feeling in the front end. I'll do the same on the back this weekend.

I'll say the same thing here.

I just finished preloading from the factory setting. I used 1/4" as my preload measurement as instructed by Pete@BC, and afterwards the car dropped 3/4" That tells you how much the springs were preloaded when they got to me.

Now, the ground to fender clearance in the front is 25.5" and the rear is 26.5". It looks pretty mean and raked, but I need to bring the front up to 26.25" for it to look right.

Now, if I could only fit my jack under the car...

ppc

Just drive up on some short pieces of 2"x4" 2"x6" etc.

I have done a full uninstall and reinstall and thought I took care of the rattle. But it has come back and is freaking annoying. Is there no new information on where the rattle is coming from or cause by?????

finally got my car back, and i did notice a few sounds when driving slow over uneven ground, like grass

i'll try to mess with it this week
