Vibration, ossolation in front suspension.

[SpyderVenom]

Does anyone know what would cause an ossolation at around 80 Mph. I drive an 87 Lebaron and you can feel it in the steering wheel off and on every 3 seconds at 80. I thought it was the drivers side shaft which I replace but it still does it. Out of balance tire maybe? Im thinking wheel bearing.

have the same problem, mine is under acceleration at certain rpm, does it when slowing down also, whole steering column shakes, let you know if I find anything.
