how do i find out my gear ratio

zers · February 10th, 2008, 01:34 AM

if it's stock there's an axle code on either the inside of the door frame, or in the glove box, I don't remember which.
For the 65 (assuming that's what you have from the text under your avatar)
1 = 3.00
3 = 3.20
4 = 3.25
5 = 3.50
6 = 2.80
7 = 3.80
8 = 3.89
9 = 4.11
A = 3.00 t-lock
C = 3.20 t-lock
D = 3.25 t-lock
E = 3.50 t-lock
F = 2.80 t-lock
G = 3.80 t-lock
H = 3.89 t-lock
I = 4.11 t-lock

no the rear end has been changed out to i think a 9" im not sure id have to check that to if i can determine the rear end will this help?

zers · February 10th, 2008, 01:42 AM

eh, in that case I think the easiest way (other than pulling it apart and counting the teeth) would be to calculate it .. though i'm not sure of the calculation, give me a minute and i'll see if i can't find it

Axle Gear Ratio Identification - GETAHELMET.COM

this says a pretty easy way to do it, by just turning the driveshaft by hand, see how long to do 1 full tire revolution

thanks! i'll try that tomorrow

nba1341 · February 25th, 2008, 03:01 AM

bump so i can find out tomorrow

nba1341 · February 25th, 2008, 01:06 PM

do the front wheels have to be suspended too???

i have drive up ramps for the front and 2 jack stands for the back would that work?

zers · February 25th, 2008, 04:45 PM

well the parking brake only applies to the rear, so to be safe, i'd leave the front on the ground, and chalk them, and just raise the back and put it on the jack stands.

460brevill · February 25th, 2008, 05:35 PM

do you have a posi?

nba1341 · February 25th, 2008, 05:44 PM

i dont think so

i dont even know what rear end i have

can you tell from these pics???

also what is that stuff leaking down from it

doesnt look right....

460brevill · February 25th, 2008, 05:58 PM

looks like an 8 inch.block front wheels.jack up one wheel in rear.put trans in neutral.turn drive shaft yoke down.mark yoke and houseing in same place.put mark on wheel.rotate shaft and count the times the shaft goes around to one turn of the wheel.now devide that.done

nba1341 · February 25th, 2008, 06:13 PM

sweet thanks

nba1341 · February 25th, 2008, 07:28 PM

i got 1 1/2 rotations of the driveshaft for 1 rotation of the tire......

what ratio is that????

nba1341 · February 25th, 2008, 08:39 PM

1 thing guys....

i had the tire spun while i counted drive shaft rotations

rather than me spinning the shaft and them telling me when 1 tire rotation was complete

does this make a difference?

nba1341 · February 26th, 2008, 06:45 PM

input?

460brevill · February 26th, 2008, 06:55 PM

you need to block one wheel and turn the shaft.
