My local dealer installed Yukon free spin kits, new Moog greasable ball joints and new universal joints this week. The installation went great. They changed my front/rear diff fluids also. The front was clear but the rear fluid was very dark like black. I am impressed with the Yukon quality and the no need to order adapters from another business to install the kit. In total the Yukon kit is almost half the cost of a Dynatrac kit and hub adapters. -- Another plus with Yukon kit, they use milled adapters which is much stronger and is more reliable that any casting. My steering is much more responsive. waytogo -- Install can be viewed at 2007.5 Dodge RAM 3500 6.7L Cummins Diesel - 245x70x19.5 wheels
