I'm not sure if I am posting this in the correct place.
I have a 2002 Grand Cherokee 2.7crd. Recently I have had a rumbling noise coming from the front end that as got worse over the last 5,000 miles. This noise as now developed and is occurring at all speeds, in a straight line and in right hand bends, but disappears in left hand bends. There is also a vibration that has developed through the steering wheel, and can also be felt though the floor. I have jacked the front end up, and rotated a wheel. It moves about an inch before the other wheel moves. This is the same with both wheels, but there is a loud clunking noise from the diff when the slack is taken up. The front prop shaft only rotates about 2 millimeters before the wheels turn. Wheel bearing seam good, no movement when I waggle the road wheel top and bottom. The diff oil is the correct level and new, about 3 years, 30,000 miles back. Also the cv joint rubbers are looking good.
Could anyone offer any suggestions as to what this problem could be.
Thanks for reading.
