I found a guy wanting to sell a set of 488 thirds out of a 94 4cyl. he said the gears are brand new. one set is still in the box and the other is instaled in the rear already. He is asking for 500 for both after he installs the front gears. Or he said 450 if i give him my old v6 410s.

50 bucks for both thirds doesnt sound like much of a deal on my end lol. so i mite end up just keeping them.

Back to my point, does 500 sound like a bit much for front and rear thirds with 488s, NO lockers, and the seller is installing the gears himself.?

By the way... it would be a 12 hour drive ($120 in gas) both ways to pick them up so what would be the best way to handle that situation?

 

Most salvage places list stock rear 3rd for $300+... so keep yours..Id do some figuring to see if you could come out cheaper than $620 by just buying gears and having them installed..is there any difference in 4 cyl 3rds and V6 thirds?

 

yeah 2 pinion carrier vs 4. and different bearing sizes. the bearings should be an easy swap though (are they)
buying gears is a good idea but probably wont be much cheaper. plus if i swap in the 4cyl diffs i can run aussie lockers right?

 

any other opinions on what would be the cheapest way of getting regeared in my situation??...

 

Find factory 4.88 thirds. They are set up from the factory so you know they are set up right. You should be able to find a pair for around 350 or so...look on craigslist and the classifieds on all the different forums...pirate, ttora, here, etc...

I got my front ifs factory 4.88 third for $150 from a guy on here but it was like 90 shipping...if you can find someone close that would be even better.

 

It might cost less to have them shipped.

 

thanks 89. i have been looking all over like crazy on CL with little luck. Washington PA and Ohio is the closest yet...

and rusty thats what im thinkin.

but about the front 8" 4cyl diff... has anyone swapped one into a 7.5 housing?

the more i read the less everything makes sense!! lol

 

An 8'' diff will not fit in a 7.5 inch housing. They are completely different.

 

If the 4.88 gears are a reputable brand, and the installer knows what he is doing, then I think $500 is a pretty fair price. The biggest concern would be in whether or not the guy knows how to properly set up the gears.

Although $50 might not seem much for your stock thirds, I'd take it. They don't seem to sell very well whenever they come up on here or other forums.

 

UUUGGGHHHHHH!!!!!! im ready to say the heck with it and let it pass till i figure everything out for sure because i keep hearing different things...
this is what i have found- http://home.4x4wire.com/erik/diffs/#front

this says: '86-95 IFS trucks and 4Runners use a 7.5" front diff that is offset to the passenger's side.


and for the rear we know both are 8" but the 4cyl is 2 pinion and the V6 is 4

Can yall please read that link over and try to help figure this out!!??

Im sure there is a few of you on here that knows the exact answer.

 

I couldln't even sell my stock FACTORY 4.10 diff for $20..

Welded it up and now its a trail spare.

 

Okay, the gears are Precision Gears. And it turns out the thirds are out of a '94 (meaning it was ifs) so the front is 7.5 and the rear is 8. with that being said, everything should matchup right?


Please help me figure this out I am almost there!!! lol

 

yup..it should..

 

okay sweet!! can someone tell me or direct me to somewhere where i can see a breakdown of what i have instore as far as swapping them out?

ohh and whats the deal with precision gears?? anyone have any input on them?

 

Here's a writeup on the front. http://gearinstalls.com/ifs.htm Taking it down is pretty easy. Putting it back up is a major pain. I'd recommend using a tranny jack.

Here's a writeup for the rear. It's a lot easier than the front https://www.yotatech.com/forums/f129...nstall-163698/

 

Thanks a bunch NG!

 

yea the front is a PITA...kinda...rear is a breeze...i use to run precisions in my 86 and had no problems

 

Alright. Thanks Bain, good to hear positive news on the gears. Im just praying that there installed correctly. rekon why the fronts more of a PITA? guessin il find out?

 

Hey, i located some factory 488s out of a 94 runner just now. the place wants 350 just for the rear and probably the same for the front too.
Should i gamble and try to save some by going with a 4cyl diff that had the gears set up by joe schmo or pay some bigger bucks and go with the yota factorys?

i mean 600-700 is alot to fork over for me but i was never much of a gambler either.
i think im just rambling now but seem to have made my mind upbut wanna make sure... again

so is 600-700 too much for front and rear factory 488s in "excellent condition"
thats about what i would pay to buy 2 sets of R&Ps and labor right?

 

6-700 is alot for just factory thirds. I got my e-locker third set up with new 4.88's and a factory 4.88 ifs front for roughly 700. That is cheaper than gettin new gears set up at a regular shop. In the end it comes down to your budget, what you want to spend, and whether or not you want to put a locker in the rear down the road.
