Can someone identify this carrier? It is in a 1988 Toyota Runner SR5 with a 3.0 and 5 speed tranny.

It does not look like a standard stock carrier.....

 

it does not look like any of mine.

it may be the vaunted factory 4.88 gear set.

although I have never seen one.

they are different because of internal component size and special parts.

check your axle/gear codes on the firewall tag and research the gear code.

it might be in the door jam.

 

Is there any coloring on the pinion end at the flange? (Pink, white, blue, nothing)

 

Looks like a factory V6 Diff/Carrier to me.

V6 are a 4 pinion carrier, instead of a 2 pinion carrier like the 4cyls.
