CubbieBlue Sorry - to recap:
Whine in first gear only.

Much more noticeable in 4WD

EXTREMELY noticeable in 4L

Shifts smooth, only 40k miles on it..hmm...

CubbieBlue Yeah you are right. So my gears look great, and the whine persists after I flushed the fluid. My buddy thinks it is the transfer case. The whine is much more noticable in 4L. Anyone have any ideas or how to troubleshoot this?

CubbieBlue took the diff cover off and everything looked great...EXCEPT there seems to be an N or an M etched into one of the gears? I took a picture. This may be damage or it may be design, I am unsure. Regardless I dumped the fluid and refilled. The fluid was real dirty compared to the stuff I put in.

Let me know what you guys think!

Also herculined my tub today....long day!!!

If you are going to replace the fluid, I recommend taking the diff cover off instead of using the drain plug. This way you can inspect the gears for any damage. All ya need is a torque wrench, brake fluid(to clean the inside), gasket scrapper, and some RTV. Here is a link for more detailed instructions:

Front axle whine

I pulled my carpets to herculine my interior and without the noise dampener a mild whine from my front axle has become noticable. I only hear it when I accelerate from a stop and it sounds sort of like how a car may whine going fast in reverse. That kinda whirrrrrrrrrrrr noise.

When I had my rear DS out and was running front wheel drive for a day or so while I got my rear DS balanced the noise was prevalent as well, but I figured it was because the jeep was not used to having all that stress on the front axle.

Is there something going on with the front axle/differential or is this normal?
