Can I use a Yukon 32 spline for my grenaded rear end? 04 4x4OffRoad w tow pkg. I hear it has like a 24 or 27?, and that they're not really made anymore??? What all is compatible and recommendations, advice greatly appreciated. I ordered a Yukon ring and pinion 32 spline kit, a master rebuild kit bearings etc, axle seals, royal purple fluid. I still need to find a reasonable spider gear kit??? Thanks Folks R.
