Determining gear ratios

Looked on the door jam of my 02 double cab for which gear ratio I have on my truck but it only talks of tire info and gvwr. How can I find out what the rear gear ratio is?

 

theres a vin code on the listing

 

Know of a good site to punch my vin into?

 

There is a thread here that will help you decode the code on the door sticker. Let me see if I can find it

Option #2 if you can't find the codes,,or want to double check.

 

Look by your transmission code

Look in the driver side door panel for the sticker.

Find the code and use this

I used this had found my answer. B03A= 8", 4.10, 2 pinion.

I'm not sure what the pinion count means but is this a pretty standard axle configuration?

 

B03A is what I have. 4.10 gears, open diff(least it was haha). 2 pinion I'm not too sure of, but I believe it has some part of what makes our diff stronger then the e-locker. Ours is often called the 8.4 diff, while the elocker is called the 8.0

 

It's a very common gear for prerunner or 4x4 with automatic v6

 

Mine has the elocker as well

 

That shouldn't be the code then. Unless someone swapped it in. Let me go double check my truck

 

All e lockers are 4.10s

 

Yep. Mines B03A. Open diff prerunner. If you have the locker someone swapped it on

 

Not true.

Prerunners did come with an e locker OEM. Some did anyways

 

Now I'm REALLY confused

 

Unless you've got 4Runner 4:30's

 

Or 4.88

But I'm not talking about 4runners. This is a tacoma forum.


Your rear diff OP is totally not all not are what your confused about

 

I know they did. Mines not a TRD. It was open, till I installed a truetrac. OP, is there a button to the left of your steering wheel, next to the light dimmer. Says RR diff lock?

 

Yep. If got the push button elocker. 02 dbl cab v6 auto trd 4x4. No towing package either.
