This is a two part question.

I currently have a steering wheel vibration that starts around 60MPH and goes away by 70 MPH. It does not matter much if I accelerate, coast or decelerate... it is always there. I try not to drive in that range. I was wondering if anyone had a similar problem and knows what the cause is.

I have not had the car aligned since I purchased 8K miles ago. The car has 160K miles. The tires are new and the problem persisted through the first tire rotation. The car does not pull much, but if it does, it goes to the drivers side slighty.

My second question involves the kind of maintainence that would be involved with the suspension on a car this age. I doubt it had been pampered before I got it, but assuming that it was marginally cared for, are there some general parts that need replacement, busings, ball joints. etc. No noises yet, only the vibration.

Thanks
