Just bought my 2nd hummer H2 this one is for my wife. After we drove it for a day we found that the rear tire or axle was shiffting. You could feel it and here it. I went and started looking and found that the bar that runs from the frame to the axle right behind the differential .the bolts were loose and was able to see that the bar was moving.
I retighten the bolts and wanted to let others know what ifound.m&b

 

Thats scary, you probably should put the thing on a lift and go thru all the suspension from front to back.

 

Going to grease the front ball joints this week.
