TOY: What diff gear ratio is this....?

[Steven Keene <stkeene@xxxxxxxxxxxxxx>]

I stripped the pinyon in my rear differential. The gear ratio was 
changed years ago but I don't know what it was changed to.  I assume it 
is 4.88 but I need to know exactly so I can replace and match the 
front.  I have 32 inch tires and the speedo reads high. 

The pinion had 8 teeth and the ring has 32 teeth.  Its an 81 long bed 
toyota.

How do you calculate this?   There are some stamped numbers and some 
numbers that are hand engraved on the gears but neither look like a 
ratio number.

Hey Steve

Are you sure of those tooth counts?  I never heard of a 4.0 gear ratio
