I have a 2000 dodge dakota. Ive beeen having problems with the rear end. It all started when i noticed the rear tires had worn on the inside of one tire and the outside of the other.. long story is now i have discovered that when it is jacked up, it is quite hard to turn the rear wheel. and when i turn one side, the other side turns in the same direction. As apposed to turning one side forward and the other side turns the other way. I took the diff cover off and everything looked good to my knowledge. Any suggestions? Thanks
