Kia said that I have been driving around in 4x4 for the last 4 months, ever since I got the rig. The vacuum lines were broken and I really didnt know what they did so I didnt fix them. Now I am replacing the lines. Kia also said that the only way to get the hubs to release was with the vacuum system. Hopefully everything works out so I can get it out of 4x4.
I got all the parts I need so I am going out to put it all back together.
