Had this been posted in the correct section Drivtrain section you would have seen the sticky at the top.

you tell 'em, STL!

STL, i couldn't find that section so i decided to post it on here because the size of your tires depends on your stock gear ratio.. one of which i can't figure out. so.. where do i do on my truck to figure this mess out? =)

thanks.

The sticker is on the door jam of the driver door.

cool, i did not realize i could click on the little rear axle code. i thought you were just sayin that haha..

No the Code is in your door jam, It will be under the "axle" section

If you can't figure out how to read the code from the door jamb/online.

Mark tire with chalk at top center.
Have friend drive forward SLOOOOWLY with friend watching tire chalk/verify 1 revolution.

You sit next to the truck and count how many times the rear u-joints spins.

I didn't have a door code
Mine span alllllllmost 3.5 times. I have 3.45 gears

Or just read the diff tag.

Some dont some do. Usually the ones that dont people were too retarded or lazy to put it back on the bolt after they finished replacing the oil or anything like that.

blackacre · #14 05-21-2011, 06:02 PM

mine says 95 as well for the axle. but what does that mean?..

DiabloBlanco · #15 05-21-2011, 06:03 PM

It means you have a 8.8 housing with 3.55 open gears.
