Grabbed a hub to hub rear axle yesterday at Pick n Pull. Now I'm unsure of its gear ratio. Is there any identifying number or mark on the axle housing itself? I have the vin for the truck, but did not write down the axle code from the vin plate. Have been through all the links on diffs here on mud.

There is a color code on the end of the pinion that may shed some light on the subject.
This should get you the info you need:

4.10 Pink
4.11 Orange
4.30 Blue

Use the color as a guideline only.... There are exceptions.

Yes I know about the colour code. My 1990 22re has a pink pinion and 4:10 gears. There is no paint on this pinion unless it is black. I tried the spin test. It is definitely over 4, but a bit hard to tell 4:30, 4:56, 4:88? Maybe the diff was worked on at some point, so no paint on the pinion? I will try the spin test again more thoroughly, maybe closer to when I want to regear, like in the spring. Just trying to be 100% sure of what gears are in there.

Just looked up the vin on the Toyota DIY site. Says the truck was a manual transmission with either 4:30 or 4:56 gears. Now I'm a bit worried that I have a 4:30 diff. Was trying for a 4:56 to run 32" tires better.

Well it's not too much work to pull the diff and count teeth, but If you're diligent about marking the pinion and brake drum/tire, the spin method should be pretty accurate.

Yeah I now think the count is close to 4:30, which means I probably have a very heavy housing to play with. I thought a shop press was needed for reassembling axles and bearing seals etc? I'm hoping to find an e-locker with 4:56 gears before I start swapping things out. the whole rear end was only $80 can or about $50 USD.
You need a press if you are replacing the bearings and seals but to remove the axles all you need to do is remove the 4 nuts that hold the bearing plate to the housing. elockers came in 4.30 and 4.10

I thought I saw 4:56 in an e-locker somewhere? Or can an e-locker be re-geared? Huge expense?
I believe you are correct. I had this discussion with my dealer (Cruiser Dan) and he indicated that a 4.56 e-locker is available from Toyota.
I'll defer to Dan's or Beno's expanded knowledge, but I can't find a P/N for an e-locker with 4.56 ratio anywhere. Doesn't mean they don't exist though.
I have re-geared several e-lockers, it's no harder than a regular V6 diff. I have one in my garage all apart now that needs pinion bearings, had 4.10s in it. But it would be a good opportunity to re-gear. Wanting to get rid of it...

You can also put I4 gears in a V6 and E-locker carrier. The pinion just needs more shims.

I noticed Marlin has them, but they are $2400. Full monsoon is almost heroes I will be keeping an eye out all winter.
