Differential Ratio

[suprra_girl]

hey
to check the ratio of the diff the way i've always checked them is......

place a chalk mark or something easy to see on the driveshaft end of the diff and a chalk mark on the top center of one of the side axles on the diff

see how many times it takes to turn the driveshaft end till the chalkmark on the axle bit comes to the top again...
generally 7mgte diffs 86-88 are 3.9 lsd and 89-92 are 3.7 i believe...

so generally you would have to turn the driveshaft end of the diff 3 times and almost one more rotation to get the ratio

let me know how you get on or if my instructions totally don't make sense lol

also.. what do you mean you can't match it with the transmission?

thanks
