Is there anyway to find out what's making a noise in my rear end? It's a humming noise that happens only when I accelerate. My jeep drives smooth it's just that noise and it's really really driving me nuts! Please any input will be greatly appreciated!

 

Anyone? Anything will help

 

sounds like gears, did you do a regear? how loud is it??? what kind of noise?

 

I have stock gears. Not sure what they are. I think its the 3.73? My friend says it sounds like a pinion bearing. Its like a whining noise only when I hit the gas. It doesn't do it when I let of the gas

 

Oh and the faster I go the louder it is

 

sounds like your buddy might be right, I would open up the diff and take a look. Or take it to the dealer, if thats an option.

 

Pinions make noise on accel or decel, your buddy sounds like he knows what he's talking about.
