Re: Is the rear diff known for whining??
Jeep stopped using Dana axles in the 05 and up WK, and the WK axle assemblies are typical Chrysler poor quality. It is not an easy task, the shims are very thick and a selection of arouind 90 different thicknesses would need to be in stock by a shop to do it correctly, as each rebuild is different. JAsper reman's them the right way, whereas most rebuilds are not shimmed to OEM tolerance.
