i was wondering if anyone knows the difference between the 2 and 4 pinion rear ends?

 

2 pinion = 4 cylinder rear end
4 pinion = V6 rear end.

 

ive done alot of reasearch and the v-6 has a 2&4 pinion in it but i cant find out the specific difference between the two

 

Not always. I have seen V6 thirds with two pinions.

 

very true, but i'm speaking in terms of generality.

an easy way to ID a "V6" 4 pinion 3rd member is that it will have 4 ribs on it, compared to the 3 that a 4 cylinder 3rd will have. however, i've heard that the 3rd and 4th gen 4runners with V6 3rds have less ribs, so yet again, take it with a grain of salt

 

aren't the factory 4.88's the 4 pinion ones?
