One problem related to front suspension wheel bearing has been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
I have a2004 chevy 3500 Silverado, with 50,000 miles on, I noticed a clicking noise in the right front. With further investigation, I noticed that the front wheel was loose on the truck. The wheel bearing was loose. I called general motors and discussed the bearing failure. I got the new bearing and started to do the repair. I noticed that everything looked new yet, but the bearing was coming apart. The bearing is a sealed unit-it is pressed together. The bearing is not manufactured properly- it is not pressed together right so that the front tire could fall off and cause serious accidents. I am sure there is alot of failure on these bearings and this should be checked out. When these bearings fail because of the pressed fit, they self destruct violently and there is no way you can look at it after it fails unless you catch it early. I caught mine early and it can be a dangerous situation to the public. I made general motors aware of the problem on their 800 number and they refused to address the problem with me.
