Differentiel ratio

[Elesage]

Hi guys,
I have 2 diffs are these the same ratio first is from a 99 limited and the 2nd one is from a 02 sr5,
If some one could tell me if they are both 4.30...
Thanks for your help

You're probably better off rotating the pinion and counting the turns.

The '99 would be a 4.30 (probably) if it was from a 99 Limited with a rear locker, 4.10 if not. That was the general pattern for automatic trans trucks (and Limiteds are all automatics).

Yeah do the spin test be be sure. Im pretty sure all 02 sr5 were 4.10 though, thats what mine was and there is no locker or stick shift option. not sure if 4cyl was offered though as that could be different.
