Front shocks...

If you still had spindles, brakes,etc... on and the shocks were keeping it from dropping, you might have something wrong. Do you have all of the bushings installed at the lower mounting point? Are the shocks adjustable?

my KYB's would bottom out well before full suspension extension also. It was good in a way, becuase otherwise the short 620 coils would have fallen out everytime I jacked the car up.

I have the same shocks and notice that last weeked when replacing my uppper control arms.

I had the front end off the ground, undid the shocks from the top then removed the two bottom nuts on the shock and the suspension jerked down an inch or two.. Scared the living crap out of me since my hands were in there and my face was about 6 inches away from the spring which I could have sworn was going to fly out at me.

I guess thats why the manual said to place the jack stand under the lower control arm(so that the suspension is compressed). I thought it meant to place it under the cam bolt where the lower arm bolts to the frame.
