Do I own a Frankenstein?
I have a 1996 4runner: 2.7liter, 5spd, 4wd.
I am trying to find out if I can put an elocker in the rear axle. And I am getting some wierd results in my search.
My axle code is an A03A...which is supposed to mean I have a:
- 7.5" ring gear
- 4.10:1 gear ratio
- 2 spider gears (open)
So...where did the 7.5" ring gear come from? I thought they were all supposed to be 8" diffs in 3rd gen 4runners.
Does anyone have expeience with these:
- are they too weak for offroading?
- can you put an elocker in this axle?
- are the axles and bearings the same as the 8", or would changes have to be made to these also?
Thanks for your replies,
Todd (unsure what to do in San Diego)

Thats the front diff, you have an 8" rear diff, trust me.

I am confused...
Thanks Crolison for the reply, but...
Based upon what I have looked at, I am pretty sure that the 7.5" is in the rear diff...and here is why I think this:
1. My VIN plate looks like the attachment. (if I can figure out how to attach a picture)
2. I understand the TM A03A is the differential designation (lower right of VIN-plate).
3. From another site, the A03A is deciphered by using a table that essentially says the 1st A= 7.5" ring gear, but if it was a B, it would be an 8" ring gear. I'm wondering if most 4runners are B's. Here is the link to the table...(yes, I know, it could be wrong, but it is the best I can find so far, that is why I asked on this site)

However, I reserve the right to be wrong!!

LOOKS LIKE I AM GOING TO HAVE TO BREAK OUT THE WRENCHS!!
So...that brings me to another newbie type question: where is the 8" or 7.5" measured (tooth root, 1/2 the tooth height, tooth end, outside dia of the ring?)

Ok...ok
The overwhelming belief is that Gen3 4runners only came with 8" rear diffs. Which should mean that an elocker would be a direct fit.
Do I need any new bearings or shims or whatever to make the system work? (My 4runner has ~185000 miles...so new bearings are probably a good idea).

yeah but it makes it easier to make one trip and take
instead of 2 trips to scope out. easier to steal out of state and
long distance. i can make a key and mail it to you....
but of course I am not a crook...jus sayin....

yep...poor choice of words by me
As an alternative, I have been looking for a complete axle at a junkyard...so far nothing close-by (San Diego). Anyone have any ideas for me? (I have looked at a site that searches junkyards...most of what I find is East of the Mississippi!)
