So, 08 AWD with 4hi and 4low...... Rattle and bank then the AWD no longer works. Like I'm coasting in neutral engine revs up in AWD now, so I switch it to 4 hi and back in business, however, the rear end fishtails like I'm in two wheel drive. 4 lows works normal. I know my front differential is toasted but is the transfer case burnt as well? It seems like there are two issues going on with this thing. Can anyone make sense of this and let me know what I'm dealing with?
