Montero sport axle, how can identify the gearing?

Found this ad on local craiglist http://sacramento.craigslist.org/pts/3768901681.html

Looks like its an axle from a Montero sport. Owner doesnt know what gearing.

How can identify the gearing inside?

Stamp? sticker? where?

Hopefully its a 4.9

Should be a sticker on the rear of the pumpkin. Mine is plainly visible.

There was a time that Mitsubishi used stickers. You probably won't find one and will have to pull the third member to count teeth.

does any one know if a 2WD and 4WD models carry the same rear axles?

The Sports don't carry the same placard in the engine compartment as the Montero identifying the gear ratio?

The sports do, yes. But it looks like the body might be missing here and no where in sight. Shouldn't be too much trouble to pull the third member, however, four bolts on each hub, pull the axles shafts then 10-12 bolts on the third member.

Well apparently there is a good chance of a sticker that should be on the axle. I just scoured ebay and found just such an example that clearly listed a 4.9 ratio for a sport rear end.

You can just turn the pinion and count how many times the axle shaft turns vs the pinion. You should be able to turn the pinion almost 5 times before the alxe shaft makes 1 turn, mark one wheel stud and rotate pinion until it comes back to it's original location. If your pinion rotates 4.9 times you have 4.9:1 ratio, 4.6 times you have a 4.63:1 ratio, 4.3 times you have 4.27:1 ratio.

Remember there are 9" and 9.5" ring gears, they are different but can be made to work in each others housings but for the sake of being an average joe job stick with matching R&P size to your R&P that will be swapped out.

That works as long as the open differential isn't also spinning too, can't imagine something sitting like that will turn very freely at each wheel, but maybe? Not sure. When thinking of the accuracy of the human eye too, think differentiating between .3-.6-.9 might be difficult. Best way to look at it is to think either 5 times -> then 4.9 just past 4 -> then 4.27 can't quite tell -> then 4.63.

I'm confident the human eye can tell the difference...
5 rotations = 4.9
4.5 rotations = 4.63
4 rotations = 4.27

Yea, that's what I was saying, guess I just restated the point made by sneakninja, just saying that being able to determine 4.9 turns probably wouldn't be possible, that's why I suggested exactly what you said. Guess I was just working it out in my head :wavey:
