I recently purchased a '90 22RE-5spd 4x4 that the previous owner mounted 31's on. The acceleration is horrid. I decoded my axle code in the door jam to see that I have an 8" 4.10 2-pinion rear end. I have decided to upgrade to at least 4.56s - but hopefully 4.88s, depending on what I can find.

I lucked out and found a local salvage yard that has the following listed:

"1994
Rear Axle
Toyota 4Runner

3.0,AOD,4X4,12-93,NOT SURE RATIO"

I called and he has the vehicle shell, and is going to get me the axle code out of the door jamb so I can verify whether it has the 4.88s or the 4.56s. Either way if I can get a good deal I'll probably buy it.

My problem comes in here: When I called and told him what I was up to he asked the year of my 4runner. I told him 1990. He asked if I have ABS and I said "yes" because I had read that ALL 4runners from 1990 on had rear ABS standard. (Is this correct?) He told me the problem is that his computer lists that the 1994 V6 axle will only work for 92-95 4runners without ABS.

This does not make sense to me, because if the info I got is correct they should all have ABS. So my question is, will this axle directly swap into my 4runner?

The other worry I have is if this is a 4-pinion, while mine is a 2 pinion. Will my driveshaft bolt up if they're different? Any problems?

Additionally, if he has the front 3rd member, can I swap that in as well? Will having/not having ABS up front affect the 3rd member at all? And will my axles bolt in?

Finally, is $310 for this rear end a ripoff? Their stock number is cryptic but I think it has 188k miles on it. Ironically so does my truck

Thanks for helping a newbie!!!!

Just found out its a G144- 8", 4.875, 4 pinion. I don't want to miss it so I hope somebody can chime in quickly...he's offering me both front and rear for $400 which sounds reasonable. He confirmed the rear has ABS so I was worrying abotu that for nothing. Just need to make sure on the 2 vs 4 pinion thing. Please help quick!!

snap-on

the diff between a ABS rear and non ABS is a tone ring on the ring gear, and an extra sensor hole in the houseing. I currently have an ABS axle (hub to hub) swaped under my truck that has no ABS. so the sensor wire is just ziptied up to the houseing out of the way.

$400 for both sounds reasonable. I know when i was looking for just a third in the 4.56 flavor i couldnt get one for less than $600 (rear only)

look them over, check the play, look at the gears (make shure they arnt blue etc) if they look good and feel good id go for it...

Justin311

Cool...thanks for the feedback. I wasn't getting responses so I just bit the bullet. $400 for both is a sweet deal I think, especially since they're 5 miles down the road from me....I can't beleive my luck. The parts guy said they come with a 90 day guarantee. I'll have them in the truck next weekend (should be pretty easy I'm assuming...anybody have a link to a how-to? the front is the main one I'd like to know how to tackle) so I should be able to evaluate them for a good long while

Oh, and is anybody else running 22RE/5 Speed/4.88s/31" combo? I see lots of discussion on 4.56 vs 4.88 in my board search, but most revolves around V6s. I figure with the little 4 banger it can't hurt to have the more aggressive gears in there. I do 98% city driving anyways!!

I had 4.88's and 31 for a VERY short time. You will be at 2500rpmish at 55mph. At 75 its upwords of 3500, drops your mileage a little, but is more responsive.

Justin311

Ah, thanks for the feedback. Since I do 98% city driving (hardly ever on freeway) I figure it will INCREASE my mpg from what I've read. I also figure if I'm over about 65 mph my mileage will decrease, but since I'm seldom there I doubt I'll ever see a decrease in mileage.

AH64ID

It depends on how you drive in the city. If you shift up sooner and keep the R's low yeah, it might increase. Your truck will require the same hp to get moving as it did before, now it will just take less time to hit the power band. If you drive with higher RPM's than before I would expect your mileage to drop.

Justin311

Actually I have heard that the RPMs do not affect the mpg as much as the throttle input. Say you give it 20% TPS and hold it until 4k and shift...vs. giving it 60% TPS and hold it until 3200 and shift. 60% TPS will always yeild much worse gas milage. I theorize that if I just accelerate SLOWLY (and the gears will help me accelerate at a greater rate with same throttle input) my mpg should improve. I guess we will find out

AH64ID

Mostly yes, but when at a constant speed a higer RPM will take more fuel....so even when accelerating more rpm requires more fuel...to a certain extent. Its all in driving style.....post what you get, before and after I am curios.

Justin311

I will. It might not be a great comparison, as I will barely have made it through a whole tank (I bought the truck last Wednesday LOL) before I swap axles. I'll be sure to fill her up and calculate it prior to the swap tho!! I am also going to take into account the 9% odometer difference between 31s and 225/75s, and then I will have to figure how far off my odo is now with the shorter gears + larger tires + stock speedo gear LOL. Too many variables!!

AH64ID

for 70 bucks LC sells a speedo corrector. If it electronic

If its mechanical you can has ISSPRO make you a custom cable with a changeable gear in it, that way if you ever do any more changes you unscrew the adapter, mail it to them, and when you get it back you have an accurate speedo again..

Justin311

I'm fairly sure its mechanical, the speedo needle bounces so usually that means its cable driven? Mine is a 1990..when did they switch to elec?

So it seems I'll have to look into ISSPRO. Do you have any links to them? That sucks toyota does not have a gear, in my jeeps/fords I just purchased a plastic gear from the dealer for $10 and it took 5 minutes to swap it out!

AH64ID

Not sure about cable vs electric..My 92 DLX is electric my 95 SR5 4runner was cable....

Well I got the rear end in and all buttoned up this evening. So far only short test drives up to 60mph...but I must say....I'M HAPPY! It now feels as it should. Before my little 1.5L Scion xB seemed like a dog, then I got my 4runner and the Scion seemed like a sports car. Now the 4runner feels nearly as peppy as the little scion.

I will do some freeway drives later this week, as well as calculate mileage and post back on differences. For the record, I went ~190 miles with my 4.10s/31s and calculated 17.3 mpg. That is with a 9% odometer correction for the speedo being off (225s vs 31s), and that is 95% city driving (half the time with the AC on!). Keep in mind I have only had this truck a week so 17.3 mpg may or may not be a good average.

Good deal, keep us posted
