My 4-runner has 2 different ratio differentials so I gotta figure out what is what. Factory 456... the rear has been replaced so Im guessing its 410's?

I've got a matching set of diffs from another runner, but I've got no idea what gear ratio they are. How do I go about figuring it out? markings? count teeth?

ring is 41, pinion is 9... no color markings. Sounds like 456.

Not just to figure out whats in my truck

best way is to count teeth on ring gear and pinion and divide. alternatly you can check the pinion nut on a stock third and look for the color. each gear ratio has a specific color.


Code:
Ratio Ring/Pinion Color Crawl:Ratio
3.42 ...42/12... Purple ...31:1
3.90 ...39/10... Red... ...36:1
4.10 ...41/10... Pink.. ...37:1
4.11 ...37/09... Orange ...37:1
4.30 ...43/10... Blue.. ...39:1
4.37 ...35/08... Green. ...40:1
4.56 ...41/09... Yellow ...41:1
4.88 ...39/08... White. ...44:1
5.29 ...37/07... None.. ...48:1
5.71 ...40/07... None.. ...51:1
