Possible you installed an incorrect bearing. Jack up the car and grab the tire at the top and bottom. Can you make the wheel wobble? There should be no play and it should feel tight. If it passes that test, then another suspension component is likely to blame and was bad before you changed bearings. Ball joints, tie rods and shock/strut assemblies are the common causes but there are others. Poke around and see if you can make anything move when exercised.

Simple things first. When did you balance your tires last? Properly inflate them.

The front anti sway bar on this car is hollow and they break. Check that. If yours is original it's probably broken! Buy the Dorman or Napa NOE replacement sway bar kit. The replacement sway bar is solid. To replace the front sway bar the sub frame must be lowered. Not an easy task without the right equipment! Hope that helps! Jim

I’d suggest a bad axle shaft. Most or the things mentioned above would not cause a vibration. Wheel balance would be the exception. That’s easy to confirm or rule out by rotating tires front to back.

Have to consider the easy route first. Could also be bad tie rod. But, this guy who posted this thread doesn't seem to care because he didn't even answer my question. Poor feedback Pont03. Don't give me points. But if this message is helpful. Give me points
