So we got some snow last night and I drove my Bronco to work, 25 miles one way. I locked my hubs just in case I needed to use the 4x4. Going about 35mph I noticed a wierd clangy noise from, I think, my transfer case. It doesn't make this noise when the hubs are not locked nor when I'm in 4x4. It's pretty loud, but that's about it. No shaking or anything. Also, the transfercase shifts from 2 hi to 4 hi smoothly, but it won't go into neutral or 4lo. When I try it grinds like crazy. I have to turn off the truck to get it into those gears on the transfercase. Are the transfercase and the tranny syncronized somehow? I have had both the tranny and transfercase out of the Bronco. Did I install it wrong somehow?
