Hello, I am new to this forum, so excuse me if this has been addressed. Has anyone experienced problems with wheel bearing replacements? I had loud tire noise for awhile, only to be sold a new set of tires at approx. 25,000 miles. The noise did not go away after spending way too much on tires, so when I went to have the new tires rechecked, I was told the wheel bearing (rear) were bad. The dealer replaced the rear hub/bearings under warranty and it was ok for a month or so. Now, the noise is just as bad as it started with ("th-th-th" sound) originally, and will probably need front ones replaced..but now the dealer is saying that I am past my warranty...isn't this a problem? (I have approx. 48,000 miles on it now)
