If you have a front end alignment problem you should be able to tell from tire wear when the car pulls right. You need to jack your car up and try turning the wheels by hand and you need to check the bearings and the other parts by doing the 6/12 test and the 3/9 test.
Try raising the air pressue 5-6 pounds on the right front tire and see if the car will track any better.
While the power steering when low will feel like it is cavitating, a air leak on the low pressure side will also give you the same symthems. Usually the air leak will produce a low howling noise when you turn the wheel hard right or left at slower speeds. Jim
