Short story first:
When decelerating (actually engine braking with no foot on gas) at over 50 mph there is a high pitch grinding noise coming from the transfer case. It sounds like gears trying to mesh while spinning at high speed. I can avoid this by A) putting the transmission into neutral until I am going slower then 40 mph or B) keep a slight amount of throttle so the engine rpm doesn't drop below around 1500.
The longer story:
The truck is a 97' Explorer XLT AWD with Auto transmission. After a few days of the grinding noise I was finally stranded on the side of the road. I took my foot off the gas while going down a slight slope in the road. The grinding noise started and then abruptly stopped but when it did I had no drive Tran. I coasted to the side of the road and had the truck towed home.
After towing it home I started the truck and found that it was mobile again. I figured out that when the truck was hoisted onto the tow truck the steep incline must have put the transfer case back into gear. I later confirmed this when I pulled the transfer case out and popped it open to find a broken gear reduction fork. I replaced it ($39) and was mobile again without the grinding noises but instead a thud. Now under the same conditions as the previous grinding noise I was getting a slite thud or clank. It was just like something spring loaded was pulled and then released causing it to slap into position.
After about 1000 miles of this the truck has returned to the grinding noise. Obviously the broken gear reduction fork was a problem resulting from some yet unknown cause. I'm planning on pulling the transfer case out again before it leaves me stranded, but I don't really have any idea what to look for that could be causing my problem. The symptoms also seem unique after Googling it for over an hour. Any help would be greatly appreciated.
