Good luck. 
...I went 4.56 with a MT, but sometimes I think I should have gone 4.88 |
That is not a part that Toyota USA sells, it is a Toyota part number.
Here is what I ordered for my install...
90311-38070 pinion seal $8.71 - the one included in the Toyota kit I used will not fit our housing...
90366-35133 pinion bearing $87.06 - not strictly necessary, but can can be damaged during removal from your old pinion shaft...
12157-10010 drain bolt gasket $1.08
SU003-00122 fill bolt gasket $1.79
90311-43009 quantity 2 differential axle seal($15.60 each)
Most differential shops stock the shims and oil - I was not picky on the oil since I changed it out after 500 mile break in. The toyota kit includes crush sleeve, new bolts, lock tabs...
Not trying to sell you on a Toyota kit; just adding info to the thread. I have heard nothing but good about the Weir stuff.
