i think that i might have figured out the vibration problem. i thought it was my wheel bearing but i asked around on another forum and i think it could be my axle binding up.
for those of you who dont remember this is what it looks like. squished.

i bought a kia sephia 1.8L BP axle off the forums. this axle is about an inch shorter but it supposed to have the same splines on both ends. an inch might not sound like much but could be all the difference! hopefully it fixes the problem! :goodjob:
