Im replacing my front right on my 4x4 and my question is do you have to spend $110 and replace the whole hub assembly or can you just buy bearings cause i cant seem to find them anywhere online.

 

You have to buy the hub assembly.

 

Yes, you have to buy the whole hub, the bearing assembly is a sealed unit.
I took mine apart hoping to just replace the bearing...not. Luckily I had a parts truck, so I just robbed one off of it.
If you only have to pay $110, your lucky. The best price I found here was $185...unless I wanted to order one off e-bay and wait for 2 weeks.
Good luck.

 

im not even sure if it is the wheel bearing anymore. what i got is this high pitched squirelling squeel comming from my front right wheel that is louder than hell between 5-45mph, faster than that any the noise goes away. When i make my turns if i make a good hard turn to the right (taking the weight off the front right) the noise goes away untill i straighten out, and if i turn to the left (putting the weight on the right) the noise gets louder. I tried rotated and balance the tires so thats out. A friend suggested that it was because the rotor was not seated REALLY tightly and to lube between the hub and the rotor, good idea i guess but failed.

this noise makes me wanna drive this wonderful truck into a river

 

Yea, its sounds like your wheel brg. Mine had the same symptoms when it "went south"
Jack up the front of your truck ( use jack stands). Grab your tire top and bottom and try rocking the wheel side to side, in and out. It should have zero slop. If you feel any movement at all,( it will feel like a slight "clunk" ), its the bearing. Make sure that you're not feeling any movement in your ball joints or rod ends.

 

there really isnt any play at all with the tire but the rotor has play

 

Hmmm...I don't get how the rotor could have any play due to the fact that it's sandwiched between the rim and wheel bearing hub.
It could still be the bearing failing...its just not showing any slop yet.
It would be nice if you had access to an IR heat gun. After you take the truck for a run, you could take the wheel hub temp. and see if one is running hotter than the other...or you could try getting your fingers in there to feel the hub if you haven't access to a heat gun ( when a bearing craps out, it generally produces heat )

 

well i just said hell with it and bought a new assembly and should get it on by this weekend

 

well it definatly was NOT the wheel bearing

 

that sucks real bad that it is not fixed. i would put it up on some jackstands and put it in gear and let it spin and see if it makes the noise so you can maybe pinpoint the location a little better
