How Can I find Rear axel ratio?

[LI Camper]

How can I find out the rear axel ratio on a 04. 5? I have looked in the truck manual and the build sheet. On the older trucks it was on the plate in the front of the truck but I can't find this info anywhere. This is a 4x4 quad cab LBW. Thanks

Open the glove box, there is a sticker on the bottom with your truck options, and gear ratio.

Thanks, I had the same question.

for future in the case of not finding the sticker or on a different truck:

if the rear is open diff. ( no limited slip or locker )

Jack up one tire , either side, mark the drive shaft so you can see the mark from the tire. spin the tire 2 complete turns, while counting the turns of the driveshaft.

If the shaft makes just over 4 turns you got 4:10 s'

if it makes 3 1/2 turns you got 3:54 s'



Now for limited slip rears jack both sides of axle so both tires are off the ground. Spin the tire 1 complete turn while counting the turns of the driveshaft.



Hope this wasn't confusing
