I'm having problems locating the fill plug for the transfer case. I
believe I've found the drain plug (just off from the transmission drain
plug). I found both the drain and fill plugs for the rear
differential. This looks easy except that filling the oil may require
some flexible hose and pump - there is no room to pour the oil into the
fill plug. Any suggestions?

By the way, I'm planning to use Mobil 1 Synthetic 75W90. Is this oil
acceptable for an RX300?

Thanks!

The RX 300 does not have a transfer case; it has a center differential. You
can access on-line access to the factory service manuals at
techinfo.toyota.com.

Refilling differential fluid requires a flexible or L-shaped nozzle and a
pump.

Synthetic oil is OK to use, however, use only the weight and type specified
in your owner's manual. Some use ATF instead of gear lube.

Thanks for the information. I went through the documentation online.
It doesn't specifically show how the fluid is changed. Any suggestions
on where the drain and fill bolts are located would be appreciated.

Obviously, the drain will be somewhere on the bottom fo the differential,
and the fill plug is generally somewhere on the side, about halfway or 3/4
of the way up.
