4.56 gears from '93 in an '87 with 4.30
I have the chance to buy some 4.56 front and rear ring and pinion from a 93 4runner for under 100 bucks. I have an 87 4runner 22RE 5spd which has 4.10 gears. What questions would I need to ask to make sure they'd fit in my 4runner? Anyone know offhand if they would be an easy swap? The reason I'm looking to swap gears is to move to 32's and not lose any power.

It's not the whole 3rds, he swapped in some 5.29's so he just has the stock 4.56's leftover.
Sooooo...even if I put 32's on my 4R with 4.10, and drove...saaaay, all the way to South America? You don't think it would be worth the effort? I was figuring it would help with MPG and power uphill (which would be nice driving thru the Andes). Basically, if the investment now saves me more money over 30,000 miles then I will do it but if the gain is minimal like you said then I'll forget about it. Figured I should give you guys a little background, to answer my query a little better.
Would it make more sense to hunt down some whole 3rds from a pick N pull? Or is that still not worth the effort for little gain?
Thanks for the responses folks, this really helps. I appreciate it!

well, it's entirely up to you.
I'd check your gear codes on your VIN to ensure you have 4.30's, and if you do then stay 4.30's
They're a good gear ratio.
4.56's would be good for 32's or 33's.
But i'd carry a spare R/P anyways if you're going on a trip like that.

I would say unless you got a screaming deal, one jump in gears is not worth it. Plug it into a gear calculator. maybe 100rpms?? 4.10 to 4.56? worth it. 4.30 to 4.56? iffy. I have 4.56's and currently with 31's, but I will be upgrading to 32's when the tax return gets here. the speedo likes 32's with 4.56's. And I do, too.
BTW, gear calculator is in the gears link in my sig

The guy's asking $75 bucks + shipping, and since it's a '93 4runner...as long as it's an 8" rear too, it should swap in right? What else would I need to consider?
Thanks again for the learnin'

Find the whole diff. Way easy swap you can do yourself. Found my 4.56 diffs for $220. Just find a stock rig being parted out with code G254 pull diff and the count teeth to double-check. Look for a 2nd gen 4runner or 3rd gen pickup with a 5 speed. Then check codes.
Click the gears link in my sig. Even has picture threads on how to swap them
