I have a 2008 H3 Alpha and apparently have a bearing or axle issue. When I go straight or turn left I get a wub-wub-wub sound that varies with speed. It doesnt do it while turning right.

I assume this is a right side wheel bearing. Does anyone know if the bearings are the same part number for both sides and if that isnt the issue if the axles are the same for both sides? Are the hubs/bearings sold as a unit?

Any other input would be appreciated if you think its relevant.

I bought it as a left over and its still under warranty (5yr driveline part of the warranty). Are axles/bearings covered typically?

 

The truck has been well taken care of and was never off-roaded. It has 45K miles 1/2 hiway.

 

No one?

 

I have the same issue, had the noises you said first and right now have a almost like popping or something noise now and i think because bearing failed. Stab failure and trac failure and abs as well.
But yes the front is sold as a unit and i have no idea if the part number is the same.

 

Much, much more likely to have a half shaft issue than a wheel bearing problem. The half shafts are the same, L & R. Have you made a careful inspection of the boots on both sides?

If you are referring to the axle shaft, the H3 only has one on the left, #21 below.


As far as I know, the front wheel bearing part is ACDelco #FW314, and it is the same for all H3s no matter which side. See #4 below:

 

Am I reading this right? The OFFroadMonster has NEVER been off road???
