Diff Ratios

[alby_39]

Hi My son just bought a 1989 62 series petrol to replace his rusted out 1982 60 series and he wants to put the lockers from his 60 into the 62. The 60 is a 2f petrol with 4spd whereas the 62 is 3f petrol with a 5 spd box. Are the diff ratios any different between the two without having to remove them to find out?

I think the 60 is 3.7, the 62 is 4.11.

Market dependent.

Thanks for the info guys. It looks like I'll have to get my hands dirty and find out for sure.

Jack up the rear and turn a wheel and count how many times the driveshaft spins. You can put a chalk mark on the driveshaft and know if it is a 3.7 or 4.11.

Jack up ONE rear wheel and rotate it TWO times (this compensates for the 2:1 ratio created by the differential action of having one wheel fixed and the other free)

sounds like a plan, thanks to everyone, now at least I dont have to take it apart to find the answer.

If you think that the truck still has the stock gears in it, check the vin plate.

Here are some references.

One of these should have the code descriptions for your vehicle.

People screw this up all the time and think they have 2:1 diff gears...

This is 100% correct.

Thanks! You're a great American.
