I took the taco to a small construction area today, and I was climbinb up a little hill of dirt in 4HI to try to take some poser shots(I know, don't flame me for this), and all of a sudden I heard this grinding noise coming from the front. I let off the skinny pedal and pushed the brake lightly. It fluctuated some and as soon as the grinding noise went away, the pedal went normal again. It could have also been the transfer case. It sounded just like a grinding transmission. Not too good. Everything works good still, but I am wondering if anyone knows what could have happened and what I can do to prevent it, because I've done it several times before and never heard this unpleasant noise. BTW, heres some of the poser pics from the hill that I heard the noise at.
