I have a 2004 Wrangler TJ and have finally got to the bottom of my vibration. I replaced all 4 tires today and got everything inspected. The shop showed me that the right rear Axle appears to be bend and has a slight wobble. I am almost certain it's a Dana 44 Rear Axle. Do I just replace the inner axle shaft on the passenger side rear? If so, what's the best place to get one. I found one a 4 Wheel Parts for under $180. Does that seem right?
