I have a few problems with my truck. Number one, I just got my clutch replaced a few months ago. Now it is really hard to shift into gear. When it is really cold out it isn't so bad. Also, when it is in 4 wheel drive and I try to brake, the tires lock up. When I make a turn while in 4 wheel drive it grinds. What the hell is wrong with my truck? Can anyone help me?????
