So I purchased a set of Rubicon axles from an individual and had a shop re-gear them to 5:13. The repair was done with the axles out of the vehicle. When the axles are picked up, I specifically asked if they had fluid in them and was insured that they did and where ready to go. Was also charged for the fluids. After installing them with in the first mile there was an awful grinding sound coming for the rear so I turned around and limped it back to the garage. Just as I thought no fluid in either axle. I will be contacting the shop Monday but at the very least the bearings are shot. Anyone have any experience with something like this?
