I received a 2006 jeep liberty sport v6 about a month ago it has 204,937 miles on it and it is making some very uneasy noises. My father and I went trail riding a week later and we put it in 4hi and the front started ticking. My dad said it was just the cv axle so i just put it back in 2wd and hoped for the best. About 2weeks later I got caught up somewhere and i had to use 4wd to get out i only drove around 50 yards then put it back in 2wd. But now when im going down the road i hear a noise kinda like metal rubbing its only when im moving. I tried putting in back in 4wd to see if it was the transfer case (i did completely stop and put it in neutral first) it went into 4hi but when i tried to put it in 4lo it started grinding. Does anyone know what is causing it and how to fix it and/or the cost??
