8.8 gear help.

Hi I have a 92 wrangler with 2.5. I have 4.10gears
I found a axle in a explorer in good condition. There is no doors so I can't see the code for the gears. I looked on the tag on the cover. It said 4L10. That's 4.10
Gears and limited slip? Is that what looking for my swap?

correct....
though it's unlikely, it's POSSIBLE the gearing could have been changed. since you should at the very least replace the fluid in it (which means pulling the cover), while you have the cover off, rotate the ring gear until you see stamped numbers on the edge... this will confirm the ratio. and while you're in there check the condition of the limited slip's S-spring inside the carrier. These can sometimes crack/break.

4.10 gears are tough to find in 8.8s - good find. What year Explorer? 1995-2001 is the best, as you get the advantage of a disc brake upgrade.

maybe it's a TX thing? when I grabbed mine, the yard had 8 explorers between 95-01... 6 of them were 4.10 and the other 2 were 3.73.

just look for the label on the door jamb and under "Axle code" will say either D2 (for limited slip) or 42 (for open)
if the label is gone or not legible, then the tag on the diff cover will have "4L10" (for LS) or "4 10" (open)

I don't know the market down there in FL, but around here that's not a bad price for a private sale or a full service yard.

Yeah it was from a yard where I found it.
But kinda off topic but my buddy has a older 350 (carbed) which runs.
What would be my best bet to get for tranny an T case?
Like a truck where I can just get both ?

any GM full size pickup from 88 to somewhere in the early/mid-90s will have a 700r4 if it's an automatic, and behind that will be either an NP231C or an NP241C driver drop TC.

you can also get an S10 pickup/Blazer if it originally had a 4.3 motor - the bell housing is the same pattern, so that trans will work behind the 350 as well.

with 33s and even 35s you should be fine unless you go totally nuts on the power. an unmodified carbed 350 is rated somewhere in the low 200s. with "bolt-on" mods (intake, carb, headers, etc) you'll probably end up somewhere around 250-ish, which should be fine for most driving on 33-35s with the D30 front. the 8.8 has been used behind mustangs with much higher power than that.

Go for it
