just swapping the center section is easy , put the car on stands undo the wheels , then undo the axle retainers 5 bolts each side & slide the axles out , undo the drive shaft , undo the 10 bolts holding the carrier in , use a jack to break the seal between the housing & C section , lift down the C section clean the housing I use the Fel Pro gasket & Ultra Black silicone to reseal it reverse the proceedure , while you are in there pack some grease into the axle brgs , they have no other source for lubrication , on 1 axle retainer on the passenger side you will find a lock tab leave this off , hit the passenger side axle with a heavy hammer to seat the left axle into the brg & make sure there is a tiny amount of end play .008- .018 , adjust the threaded coller to set end play & install the lock tab to hold the adjustment , Add synthetic gear oil
this can be done in 1 hour or less
