i've never been able to get a concrete yes or no whether the carrier is the same as a regular V6 one. some say you can install an arb or other lockers, others say you can't.

from what marlin says about these strange diffs, is that they're actually technically better. having a thinner ring gear is less rotational mass, and a thicker pinion head is always a good thing. toyota has no carrier breaks like a dana axle so all the gears have to be made to fit stock housings, at least for the most part

Yes it is. I have one. Unfortunately, I have ABS so I sacrificed it since my 3rd doesn't have the whole.

I have front and rear ARB's in my Factory 4.88 setup and they work perfectly.

Robinhood150

Wait, wait, wait...everybody needs to specify whether they mean front or rear. I get the feeling some people are talking about the fronts while others are talking about the rear.

RobG, do you still have the factory 4.88 gears too?

RobG

My gearing is all stock, Factory 4.88's. Only addition were the front and rear ARB Lockers. No housing changes, No gear changes. Been running them since about April or so with no problems.

Robinhood150

This is my understanding as well, the fronts are the same no matter the gearing.

The one I may be selling is my original factory 4.88 3rd (including the gears all set up) and this one does have the abs hole. I just swapped it out for a non-abs third with 5.29s and an ARB.

hey steve

i think im on the right page with this gearing thing, the question i have is: on my 86 & 89 the gear codes are g292 which tells me they are 8"/4.10/2 pinion, am i able to use those to regear to 5.29's to fit up the 33's to go with the auto tranny? from what im understanding here, i have to remove the existing 4.88's w/carrier to regear with the 5.29's and reinstall them. the carrier refers to the entire centre portion of the rear axles not just the 'guts'. correct?

thanks,

lee

I don't want to give out any incorrect info so I'll let somebody else answer. If nobody answers I'll throw in my 2 cents.

bump!

for axle codes please read this:
http://www.off-road.com/toyota/tech/other/4_axles.html

some examples: G254 = G=8"housing 25=4.56 gears 4=4 pinion axle(meaning v6 or turbo rear axle a 4 cylinder is a 2 pinion)
G144 = G=8"housing 14=4.88 gears 4=4 pinion axle
G282 = G=8"housing 28=4.30 gears 2=2 pinion axle

thanks for the link, got it in my favourites now. maybe i didnt explain my question properly, robinhood said he swapped out his stock 3rd (v6 auto) for one he could regear. i wanted to know if he meant just the 'guts' or the whole centre housing. i was under my truck today doing the diff breather and sort of answered that question by checking to see if the axle tubes could come apart from the centre housing. i have an 86 & 89 that im canabalizing, they are providing me with two sets of diffs which i can get the 3rd's from. am i able to swap out the std 4.88 carrier (v6 auto), replace it with the carrier from either the 86 4 banger 5 spd or 89 v6 auto regeared with 5.29's to work with 33's? i hope someone can make sense out of this mess i just posted! thanks for any help/ suggestions.

He swapped out the third member - that's the entire removeable section, (and the differential and gears that will come out with it.) Not the axle housing. I think that's what you're asking. Here's a pic of a complete third member, clipped from Marlin Crawler's site:

hey flamed

i guess someone was able to decipher my question! now that i know what it looks like, i can start the removal from the two donor trucks. ill get them out, cleaned up and inspected to see if they are ok. im thinking at least a rear locker as my first major mod, so at least one of the rear 3rs should be able to be set up. just have to ask robinhood/corey about the abs. thanks kindly for your help. im sure ill have more questions for you soon enough!

This thread has given me alot of info. One thing I'm wondering is how much does something like this cost? I have a 92' 2wd 3.0 pickup auto and it will probably need a new diff soon. I'm going to get bigger tires so it may have to get re-geared as well. I also hate the fact that I only have one tire spinning in the back so a LSD looks prety good as well.
I know new diffs are high up there in costs so I'm wondering how much the re-gearing and LSD is?
