Hey everyone

My 94 Touring seems to have developed a bad case of vibration. I've search the forum under "vibration, shaking, and rattling" but couldn't find anything that address my problem. Unlike the other vibrations caused by RPM, my problem seems to be speed related. When I start driving the car would run nice and smooth, but when I reach speeds of 50-60KMS the entire car would vibrate and I would hear a loud rattling noise coming somewhere from within my dash area. A passenger of mine commented that it felt like she was sitting in one of those massage chairs. Once I pass 60-65KMS the vibration would go away and the car would be smooth again. I've tried driving 50-60KMS in 2nd, 3rd, and 4th gear but it makes no difference no matter what the RPM is.
I have also noticed that whenever I turn right, everything would smooth out. I've been playing around with various speeds, rpms, and directions and it seems that the only time my car doesn't vibrate is when I'm turning right (especially long sweeping rights).
What could be the cause of this problem? Alignment problem? Wheels out of balance? Wore bearings?
If it helps, I am currently running Koni adjustible shocks, lowering springs (don't know what brand cuz it was already installed when I bought the car), and Yokohama Nexus tires. Has anyone else experienced this problem? I'd greatly appreciate any feedback. Thanks!

Bent rim, out of balance wheel or wheel bearings would be my guess, but more than likely just out of balance (hopefully, since it's the cheapest)

yup either ur rim is bent or your tire is out of balance or maybe even an alignment could be in your future.

Thanks for the replies! I'll take my car to a tire shop to have the balance and rims checked out. Hopefully it's just something minor. Thanks again!
