Wheel Bearing Failure?

Does this sound like a bearing is failing? 2004 KC 4x4 with 76,000 miles w/stock tires and rims with even wear on all tires. At all speeds I get a humming noise that sounds the same as if you are in 4high on pavement (definitely not in 4x4), when I turn left the noise is reduced. There is no play in the wheel at all, only the noise. I jacked it up, put in 4high and ran the rpm's to 2000 then listened to both hubs with a stethoscope. The passenger front is quite but the driver front has a definitely noise coming from it.

I took it to a dealer who said the bearings are fine because there is no play in the wheel. I am now being told by another mechanic that the "cartridge" type bearing wont wobble until the last couple hundred miles, then it fails. He also said the noise is what you will notice in the beginning of the bearing starting to fail. The non-dealer mechanic is saying that if the dealer is only trying to "wobble" the wheel to test the bearing then it will appear fine because it isn't to that point yet, but when it does wobble it will fail fast. Does this make any sense??? Not sure if I should change the hub assembly or not.

Re: Wheel Bearing Failure?

Yup, the races and or rollers are starting to get flat spots on them. its a fairly quick and easy job to replace them.

The very existence of flamethowers proves that sometime, somewhere, someone said to themselves: "You know, I want to set those people over there on fire, but I'm just not close enough to get the job done."

Thanks for the reply, do I have to change the entire hub assembly?

Re: Wheel Bearing Failure?

yessir thats your bearings, be ready to replace the pass side soon too they usually go around the same time... I believ the bearings are indeed part of the hub? But that's an educated guess don't quote me on it

Re: Wheel Bearing Failure?

normally. you wouldn't have to change the whole front "cartrige". wheel bearing races are made of a hardened steel and ground down to a near perfect finish, as are the roller bearings. Historically, you would pound out the old races and bearings, and replace with new. I can only guess that the Titan front wheel "cartrige" would be the same way. pulling one to find out, or finding someone who has an extra will be the best bet for the answer. front wheel bearings are not hard at all.
