A few days ago my front end started groaning/squeaking when I go over bumps. Now it does it all the time and it's drivin me insane. It changes pitch when you turn the steering wheel. It sounds like something needs to be lubricated that isn't. I took the wheels off and checked everything over and everything looks ok. Sprayed some lubricant on everything and it didn't help at all. Short of throwing new parts at it, what could I rule out? If you push up and down on the car it creaks and groans on the driver's side. I have heard other Ford's make the same noise, so I think it may be a somewhat common problem. Any suggestions?
