Checked the tranny and front diff fluid. Both were light brown in color and clear (I know that the transmission fluid needs to be red, and I'm planning on changing it soon). Both were registering full as well.
Kramm, I'm having the opposite problem. The noise isn't apparent when the car is cold, but only after it's warmed up for a little while.
I'm going for a ride with a gearhead/ mechanic buddy of mine who's way better diagnosing things like this than I am. So I'll be back with what he says later on.
