I have a issue with my 92 Marquis. As soon as I start to hit the gas i get this weird vibration, it seems like something is rubbing on the drive shaft. But when I turn left everything is fine until I straighten the wheel, then it comes back.


Could this be a brake problem or a suspension issue(ball joints,tie-rod)


Please help.

 

a braking issue would come and go as you depress and let off of the brake pedal. try jacking up the front end and shaking it down, checking for extra play in the front tires...

 

do you get the vibration in the steering wheel or at your feet? If you get it in the wheel sounds like a wheel bearing. If you get it at your feet under acceleration,sounds like a timing/ignition issue.
