I ve got the factory 4.88's and I have a locker in the rear, I want to switch to 5.29's so I need a new 3rd. I just bought a 4cyl. 3rd to go in my rear end. Id like to use my current locker in that housing is this possibe. or do i need to buy a new locker. BTW I have a detroit EZ locker.

 

you probably have to buy a new 2 pinion style EZ locker. (your other one is most likely 4 pinion)

 

come on guys.....

I know there is a difference with the bearings or something but is the carrier that different?

 

Well yeah, there is a difference. The carrier bearings on a 4cyl are 45MM and the Carrier bearings on a v6/turbo diff are 50 MM. The differential carriers are the same, even in the off-set housing, "special" factory 4.88 units.

Now the good news is that you want to use a BIG BEARING carrier in a little bearing housing. This is the same thing as putting a ARB RD23 (v6/turbo locker) in place of the old RD01. You just need to find and install the right bearings.

toy carrier bearing 50006

 

not tryin to jack the thread but i have a turbo and need 4:88's is there a factory truck i can get them from?Did i understand that right? what year and package would i need it off of?

thanks

 

well if you want a locker maybe ill sell ya mine..
2nd gen 4unners, auto, with 31's from the factory, had 4.88's. BUT the 3rd member that it comes in will ONLY work with those gears so if you want to step up to 5.29's you need a normal 3rd. Other than that they are great.

 

You need the 4.88s from a Gen 2 4runner that came with an auto tranny and the 31 inch tire option. Check your PM.

 

the front IFS 3rd though, is exactly the same as the rest of the IFS 3rds, so the gears will interchange

 

good point, Napoleon047
