My friend is going to buy a 1990 4runner for parts. It's a 3.0L with an automatic transmission.
Could this have 4:56 gears in it? I could look in the door when we go to look at it (sometime this week). I'm wondering because I'll go half with him.
Seller wants $400 It's rusted really bad.

I think 4:56 would be better in my truck since I put the 31X10.5 BFG M/T's on it. It had P225/75 R 15's.

 

pretty sure 4.56s where only if it had 31s . i think the autos had 4.88s

 

Auto has 4.30 stock, if had the 31" tire option, then may have 4.88.
Pretty sure 4.56 was for 5 spd w/ the 31" tires, 4.10 stock.
The math works out that way at least.

 

my 91 pickup auto 22re with 235's came with 4.56's best way to tell is look at the code on the door jam

if your friends truck doest work out i am selling a front 4.56 third..mint shape

 

A 90 w/3.0 Auto if it had 225's will have 4:10's (unless itwas regeared)
22re and auto was 4:30

 

If it came with 31's and auto it will have SPECIAL 4.88's. These diffs can't be regeared due to an offset pinion - nobody makes the unique gears they have.

 

We will look at it this weekend. I'll check the code on the door jamb to be sure. We did just look at a 1994 ext. cab truck (parts for me). the truck was rolled, hit a guardrail and landed on it's tires. Needs a cab and bed.

 

we parted a 90 V6 auto and it was 4.10 (in my son's truck now)

 

My '95 3.0 auto came with 4.56 gearing. It's a manual now...4.88's would make it perfect for my 33" tires.

 

2nd Gen auto 4Runners came with 4.56 gears with 225 tires and 4.88 with 31's.
