I had a bad drivers side wheel bearing from the day I bought the truck (brand new). I didn't recognize that the wheel bearing was bad until the truck started shaking during a snow storm in 2004. Even then, I didn't know. I replace front brakes twice, and front rotors twice. Took it to dealer who replace back brakes and rotors at my expense, Finally while rotating tires, I shook the wheels and had some movement in one wheel. I tried to repair it myself and had purchased a timkin replacement wheel bearing, but couldn't get the old one out, and so took it to the dealer which told me they couldn't use the one I purchased, they would have to use a Chevy bearing which costs several hundred more. The truck had 50,000 miles on it by this time and the dealer never recognized I had this problem. After repair the truck felt brand new.

Noticed the problem after getting confortable to the truck once i bought it. everytime i hit a pothole or a bump or even slightly braking on a hill, i'd hear a loud chater under the steering wheel and pedal compartment..... finally had the money and ran out of patience with it and took it in... First trip replaced my tie rods because they were worped or something (who ever really knows what it was) and said it'll be just fine now.... no. about oh.... 5 months later i again ran out of patience with it and took it in same place goes oh lets check it out.... my front left bearing was shot and the rotor was really warped.... be about 800 bucks to fix. (note: when they said it should solve the problem) so i called another shop and they can fix the problem no big deal.( said the chatter is ultimately the ABS over working) said the rotors can be replaced but do them when you redo your brakes they changed the bearing and presto. no chattering. cost me a pretty penny on a truck that should have withstanded a freaking bump. common.....
