4.56 gears
« on: Aug 28, 2018, 03:05:24 PM »
I recently upgraded tire size from 225 75 15 to a 31 10.5 15.

I have been planning to put gears in since I did the swap.
Since I recently started automotive class at college and i need a project for manual trans class I decided this would be a good one.

Currently has 4.10 gears.

So my question is, what is the best 4.56 front and rear gear for a 94 22re?
I would prefer less expensive gears since I am in college and dont have the money to drop in 500 dollar a diff gears.

Also any extra parts or tips for installing them.

Thank you in advance.

Your best bet would be to go find oem toyota differentials already setup from the factory.  You can find these for pretty cheap at many junkyards.

With that being said..  if this is strictly for a learning process. I would still find a set of “low mileage” 4.56 diffs from a junkyard for cheap. That way you can swap them into your truck and drive it. And regear your current 4.10 diff.

If that is not something you want to do and you just want to buy gears, a lot of people recommend Yukon or nitro gears.

4.56 isn't really worth the hassle.    You can get away with 4.10 with 31s

4.88 will give you more torque at the wheel and better acceleration.

And you'll be set up for 33s if you want to later

I really liked my 4.56 gears with my 31's.  It was definitely an improvement from the stock 4.10s. 
I do agree though if you think you might go to 33's go with 4.88 gears.

Now I am totally confused (a frequent experience). 300K is suggesting I do 4.56's with 33's and 35's on the Montana Runner (1989 4Runner on a 94 truck chassis).

I had a 22RE with the 4.56 gearing.  If it was a 3RZ that could change things.  The 22RE is not a powerhouse so gearing is your friend whether it is in the diffs or in the t-cases or better yet both.

You are going to be hard pressed to find new gears for just a couple hundred dollars. Would just start looking for used and be happy that you end up finding some.

I would bet 99% of folks could not tell the difference between 4.56's and 4.88's if they drove the gears back to back.

Folks get way to "religious"  about what gears you must run.  Like Dingman said go search for factory diffs.  Lots out there in great shape for cheap

Thanks for all the info.
I never really thought about checking around for gears or diffs from a scrap yard.
Going to try a scrapyard that should have a 90 4runner with 4.56 gears.

Will update later this week.

I found 2 4runners one has a 4.56 and the other Is a 4.88.

My question Is, can a 4 pinion ring gear be used in a 2 pinion diff?

For those wandering the 1990 4runner is a v6 with diff code g254 and the 94 is a v6 with code g144.

In case it isn't a mistype, G254 is 4.56 gears.

With this being a class project, I am assuming you need to do more than just remove a 3rd member and install one.  If so, I would just rebuild the diff of the gear set you are going with, the install it in your truck, along with the IFS axle assembly.

Yeah it was a typo.
If the 4 runners have coil spring rear suspensions would that cause a problem swapping them into the truck?
Also, would I be able to just take the gears out of the 4 runner 4 pinion and put it in my 2 pinion or will this cause problems?
I've read that the carrier doesnt swap but I haven't found any info on gear swaps from a 4 pinion.

No, the type of suspension used would only be an issue if you were swapping in the entire axle, all you are after is the 3rd member.

Not sure.

The V6 carrier is a stronger unit, with either gear set you go with I would just pull it down and rebuild it with new bearings and seals, or swap it into the truck and just do a rebuild of the stock 4.10 3rd differential for the class.

I read somewhere that the 4 pinion also had 30 spline axle shafts. Do you know if that is going to be a problem or are mine 30 spline?

All the Toyota 8" diff axles are 30 spline, front or rear, the v6 3rd will drop in w/o issue.

Ok, thanks. I will look into getting the 3rd member.
