yeah 4.88 was a factory option, I don't know what years.

but you will run into trouble if you want after market gears since the carrier has an offset for the ring gear,
a friend of mine had to buy 2 used 3rd member because of this.

Ok i dont remember what year they came in them but i know it was in auto tranny versions of trucks and 4 runners i have a mag or a book that tells you about it ill see if i can find it and get back with you.
If you didn't make it, and it ain't broke, you didn't try hard enough.

All 88-95' V6 auto's with the aluminun rims [big tire package] had 4.88 r&p's.

88runner is correct :thumbs:
Instead of making a new thicker ring gear casting to fit the 4.10 diff housing, Toyota chose to simply cut the proper teeth on the 4.10 ring gear forging, and then made a new diff casting with the pinion moved closer to the ring gear.
This is a better design, since there is less enertia in the thinner [stock style] ring gear.

Remember, to obtain a higher numerical ratio, the pinion must have less teeth [smaller diameter], and the matching ring gear will require more teeth, but it must be thicker so the gears will mesh with the smaller pinion head.

The problem is that all after market r&p's have a thicker ring ring, so if the factory 4.88's fail, only the Toyota gear sets will fit. Hope you have $$$$$$. It is very hard to tell between a 4.10 and 4.88 casting.
