I recently purchased this vehicle and notice when on the highway the car will make a humming sounds when I hit the gas excellerator at high speeds. In addition, the car pulles to the slightly when cruising on the highway and pulls to the right when slowing down. Could it be the break? The right front tire is worn more than the others. Other than that the car runs powerful and seems to be ok.

Ok lets start with the tire wear. I would say check out he upper control arm and ball joint and also check out the hub assembly on that same side. The hub could be the noise and be what is causing the pull and tire wear. If you turn from side to side does the noise change? Lets start with that and see where it goes from there ok.

That is why I would like the hub assembly checked out it very well could be making that noise. If there is a problem with the control arm like a bad bushing or ball joint that would just cause tire wear, but the hub if it is bad enough can make noise and cause tire wear. So lets check that out first and go from there.
