interesting sound in 4 wheel drive
I have a small whine sound that almost sounds like a bearing or vacuum noise when I switch to 4 wheel high and low. I often use 4 wheel drive and have never heard this sound before. When switching to 2 wheel high (from the dash control) it continues for a bit until I get over 30mph and then it goes away. Thinking it might be the vacuum (shift on the fly from the console) I then turned the hubs (left the dash control on 2 wheel mode). It still does it, but when I turn the hubs back to 2 wheel position it immediately goes away. Everything functions
normal, just concerned about that whirring/whine noise. It doesn't sound like any gear related sound. Any takers on a probable cause. Only have 22K and may have the dealer take a ride along...
Thanks for any input.
