take car out of gear (neutral)
remove wheels
remove axle cover
remove the cross pin retainer bolt (5/16 wrench)
slide the cross pin out
push axles in and retrieve clips with a magnet
no need to remove the preload spring
dont be surprised if the carrier retainer bolt is broken
its usually broken at the last thread leaving the pin and a thread stuck in the housing which prevents removal of the cross pin
it should look like this (napa has them)
