Hello everyone. First time here, and looking for some help. I parked my truck after the winter, have company vehicle and wife uses Matrix in summer. I brought it out to tow a car trailer and noticed that the 4x4 is sticking in gear. It will come out if you go forward and back a little bit. Also in 4x4 when turning the front end jumps. When you get it out of 4x4 and turn the back tires are now scuffing as though the posi is stuck. Anyone have these problems or know how to solve them, some help would be greatly appreciated. I guess she doesn't like being parked! Maybe a good drive to help loosen things up? I originally posted this in general discussion but then found this forum, sorry to anyone reading duplicate.
