Well I have the stock gear removed from the housing,not to bad a deal taking it apart.The synthetic gear lube is kind of a milky gray color.One intresting find was,there were no thin side shims found behind the carrier bearings...just one thick,.265 and .279 shim on either side. Was hoping for some thin ones in there to help balance the backlash. However,I have a huge selection of them,that came with the kit. Part II of gear swap will take place tomorrow. Oh and the rear brake calipers are really simple to remove! Need to make up a tool to hold the pinion flange,while torquing it up for install. Driveshaft weighs 22 lbs. for the record.
