2- before you tear it down, check the backlash and inspect the faces of the pinion & ring gear for imperfections. If they look OK check the mesh pattern using gear marking paste. I mix injuneers blue with a little white grease to get a medium blue color. You are dealing with the ring gear at this point. There are plenty of pictures on the internet of the correct pattern. The convex side is the drive, concave reverse/coast. Paint the teeth at several points around the gear, turn it a few revolutions in both directions by the pinion, keeping a drag load on the ring gear, or turning the ring and drag on the pinion flange. The contact area will show up as nice smooth shiny spots, in the correct location on the tooth faces. If the mesh is good, the gears are likely OK.
Note if the pinion or carrier bearings are obviously worn, or if the unit was run low on oil, it will likely have lost it's good pattern and will have some abnormal wear, and many times it's impossible to restore it to a good mesh. A less than optimal mesh pattern will usually work but it will make noise & have a shortened service life .
3- no spreader required. You can lever the carrier out with a big bar between the carrier housing and the case. It should be a little snug, due to the carrier preload but it isn't that tight. Refitting the carrier is a little fussy but no problem.

: Find a parking lot or someplace where

: You really have to partially
: disassemble the suspension to check the
: wheel hub bearings but if they are real
: bad you can see movement in the hub
: relative to the axle shaft as you jack
: it up and take weight off it.
: Driveshaft balance is a big issue on

: slider is in good shape.
