Loud "whine" while in 4-hi

[moto_head90]

When I drive around in 4-hi, there is a whirring sound coming from the front axle that gets louder and louder as I go faster. When I let off the gas, the noise quiets down significantly, then when I give it gas, it starts to "whine" again. Also If I brake fairly hard, it will "whine."

Are my gears shot or something??

Sounds like you have a pinion depth problem. If it was a bearing it would be doing it all the time. But to verify it I would take it to a shop that does alot of rear ends and drive axles. They will be able to diag the problem better.
