Ok, here's what's happening on my 02 Santa Fe LX AWD with traction control\nand ABS with 44780 miles. When I am either maintaining or slowly\naccelerating (10-15% throttle) from 35-45MPH I get a strange strong\nvibration coming from the front end sometimes (About 20% of the time). The\ncar does not pull to one side or another, and the vibration goes away if I\nalter the throttle position (More or no throttle). There is no noise except\nfor the vibration. It also always shakes a little (Barley noticeable) from\n35-45MPH. Other than that it is smooth, no pulling, no warning lights ever.\nI have rotated the tires and no difference was noticed. And now a little\nback ground info, about the same time the vibration started my car stopped\nsquealing. The squealing happened after driving 5 miles or so and would\nstop when breaks were depressed, or driven over 30 miles) otherwise it was\nnon-stop and loud, I checked the brakes and there was plenty of material,\nand of course my dealer could never reproduce it and since I picked up after\nhours, I was unable to show them. After talking in the santafeforum.net\nthey told me it was a caliper problem and they just needed to be cleaned, so\nI just dealt with it as I did not have much time or money to get it worked\non. This went on for about 1000-2000 miles. So my theory at this point is\nmaybe a wheel bearing went bad, and that was the squealing and now the\nbearing is completely shot? Is that covered by warranty? If not on average\nwhat is the cost? Anyone have any other ideas? Gas mileage on a 125mile\nhighway trip today was 22MPG done the scientific way (same pump, same gas\nstation, and filled until the gas was visible and did not go down anymore).\nI have nothing to compare gas mileage to because it's my wife's car and I\nnever watched MPG, I just made sure it got regular maintenance, gas was\ntaken care of by the wife. Thanks for any help in advance!
