ebomberger Posted May 9, 2007 Report Posted May 9, 2007 I need some info. My truck has been riding different lately. It doesn't really matter how fast I'm going, but when I let off the gas I hear this almost like humming sound coming from the front end. And every once in awhile I feel a vibration with the humming. I'm think it might be the driveline. It's never been lowered or anything, it's completely stock. Can any one give me some advise? Quote
montanass Posted May 9, 2007 Report Posted May 9, 2007 I'm gonna guess that the humming noise you hear is the front carrier bearing in the differential, and the vibration could be linked to that or your tires could be out of balance. Quote
nixsupersport Posted May 10, 2007 Report Posted May 10, 2007 mine hums when i'm on the gas, is that the same prob??? Quote
misterp Posted May 10, 2007 Report Posted May 10, 2007 I need some info. My truck has been riding different lately.

I'm think it might be the driveline. It's never been lowered or anything, it's completely stock. Can any one give me some advise?If you kick the tranny into neutral (coasting at speed) is the humming still there? better? worse? If the vibration is still there in neutral then the problem is most likely the suspension/running gear, not powertrain... mine hums when i'm on the gas, is that the same prob??? Does it happen at specific speeds? Better behaved at some speeds, worse at others? Mr. P. Quote
nixsupersport Posted May 10, 2007 Report Posted May 10, 2007 mr.p.......my humming is at any speed..example i'm driving down the highway at 65 mph., let off the gas, and slowly re-apply gas, that is when it hums.......i was told it could be the intake??? but the only time it hums is when i slowly apply the gas after any speed thanks in advance, and always MR.P FOR PRESIDENT Quote
ebomberger Posted May 11, 2007 Author Report Posted May 11, 2007 I notice the humming sound at different speeds. It almost sounds like something is rubbing on the front tires. I checked the tires and everything is good. I'll try coasting in neutral and see what happens. Thanks P Quote

ebomberger Posted May 11, 2007 Author Report Posted May 11, 2007 does anybody know how to replace the carrier bearings? Quote
perk03z06 Posted May 11, 2007 Report Posted May 11, 2007 does anybody know how to replace the carrier bearings? Yeah ... you have to take it to someone that can rebuild a differential ... because the carrier bearings are inside the diff. Quote
