That is true for Semi Floaters. Full floating rears like on FZJ80s and non-USA cruisers have a seal like the front that keeps the 90wt in the diff side and grease on the bearings. Full floaters use a pair of tapered bearings that are preloaded with a big nut just like the front, semi floaters like our USA-spec 40, 55s and 60 series (and FJ80s) use roller bearings which ride inside the seal and are lubricated with the same 90wt as the diff.

As far as Corbet's question, I have always used regular Valvoline red grease on my rear full floater bearings.
