My van has had an issue that I can't figure out. First of all, it has an intermittent vibration at highway speeds. The tires have been rotated and balanced multiple times. The vibration comes on around 75 mph; sometimes though, it doesn't appear for a few weeks, then comes back. Second, I have been getting a pulling feel in the steering wheel when I make small adjustments at speed. Third, when taking off, and sometimes when the car is coasting down, I feel a big clunk. If I'm turning right into a parking lot, and there is a curb or a little incline, the whole driver's side front end feels and sounds like it's going to fall apart. Sway bar links and axles are all verified in good condition so it's not those. Van does have the original control arms though.
