I just scored a set off a 94 Runner. I posted in a thread awhile back about how rare they are to me up here. Aside from the one other 4Runner in my yard that had 4.30's, all of the other trucks have 4.10's. I stumbled across this 4Runner in a local u-pull-it yard with 4.88's gear code G144. Of all the trucks I have seen, all of them but the two listed above had 4.10's. How rare are these gears anywhere else?

they are common enough that i was able to find 2 chunks to put in my '79 pickup. they aren't super common, but definitely not ultra rare either. the only downside is you can't regear the rear 3rds with anything other than the factory 4.88 gearset. lockers fit the carrier fine.

Yea i have stock 4.88 gears suprisingly...and im extremely happy with it

My 93 ext-cab came with them. They came on the vehicles with the 3.0/ auto tranny AND the 31" tire package in the area of 92-95. I think only the SR5s had the 31" tire package available on the pick-ups.

From what i've seen they are actually pretty common, usually run about 200$ for the diff. out of a junkyard.

i had 31's from the factory on my PU but its FAR from an SR5. 5speed and 4.56

you are correct that they only came in the autos. AFAIK

mt_goat

Thanks snap-on, I stand corrected then.

JamesD

For each diff? Did 4.88's only come in V6's?

James

kyle_22r

yes on both. V6, auto, and 31" tire package, that's what makes them sort of uncommon. 5 speed trucks with the 31" tire package got 4.56s, 4 cylinder and 6 cylinder.

I have them. I wanted to know if it is the same situation with the front gears as far as not being able to regear.

JamesD

I can't find anything either for the front. The rear we know you can't. Anyone?

I have them. Good thing too.....3.slow and auto needs 4.88's unless you run 28" tires

kyle_22r

the front takes normal 7.5" gears. the rear offsets the pinon to be able to use a thin ring gear compared to aftermarket R&P sets. that's why it can't be regeared with anything other than another toyota 4.88 set -- no companies make replacement gearsets for that particular diff.

to make it wierder, in australia(and other countries i'd imagine), you could get '79-83 trucks with 4.88 gears, but they were a standard 4 cylinder 3rd member and were regearable with aftermarket gears.

so i guess that means when i regear to 529's my 488's may not be suitable for people wanting to utilize 488's & 33's?

you can't regear a factory 4.88 3rd member to anything else, you have to get a "regular" V6 3rd. the factory 3rd member you have will work just fine in any 8" rear end, you just have to want to keep the 4.88s or be willing to swap 3rds if you want to regear.

i've got 2 V6 3rd members with factory 4.88s in my '79 4x4.

ive got a rareish diff i think.

i have a 89 3.0 5speed with 4.56 gears...is that weird?
