I am hearing a faint whining sound when cruising at 45 mph, and at this speed, if I give it just a little gas pedal or no pedal at all, I hear no noise...It is just when I am crusing & maintaining the gas pedal at this speed that the whine is just barely audible...

The only thing I did around the same time, coincidence or not, is change my
transmission fluid, replace the filter & gasket, thats it!

Anybody want to weigh in on this?

yah i have the same thing. mine starts when i apply the gas pedal and has that faint wine from around 60 and up...but yah only when i apply the pedal. as soon as i let off it cuts out. it litterally happens as soon as i apply the pedal but has never really gott'n any worse since i bought it. should get it fixed sometime tho cause its annoying on the hwy.
im assuming might be transfer case but i really don't know for sure. havn't really looked to much yet.

Yea, but mine just started doing this, im sure I didnt have it before, just started noticing it though, 120,000 on the Dak, but only 10k on the Trans.

So nothing to be too concerned with then??

To answer your question, the pinion bearings are in the rear diff.
So if the bearings are going, does this amount to new bearings only, or gears as well?

good to know...... one question tho.. why is it that the noise only happens when we apply the gas pedal? just curious how it works to make it only happen when the gas is applied

That's the only time the bearing is under pressure. When you're off the gas, it in the 'coasting' mood so to speak and has no pressure.

So no whine, no problems? I'll take it....:funny:
