Replaced the differential in the transaxle while the transmission is still in the vehicle. Differential carrier bearings died, and the gears were badly worn, had about 30 degrees of rotation of the wheel before the small gears contacted the next tooth, and a lot of end play on the passenger side cv axle. Was noticeably weeble wobbly right where the shaft entered the diff.
The fun part was sourcing all the parts, original parts are unobtanium, so had to cross reference the bearings, seals and replacement differential assembly to find suitable replacements. A month later and parts are finally starting to trickle in from various transmission rebuild shops and rock auto. What a nightmare this turned out to be, but hopefully the elves in there will stop hammering after this is all said and done. The vibrations were “HEAVY”. Like something was playing the sledgehammer right under the floor under the pedals.
