I installed my eibachs prokit springs, and tokico hp shocks about a month ago on my honda civic 2000 EX, and i haven't really had the time to fix it, but now that i just remembered. when i go up a driveway or up a speedbump, i tend to get creeks on my rear(bothsides). also ride past bumpy roads, i hear squeeking from the rear as well(both sides). none of this happens to the front of the car though. information will be helpful. thanks
