Finding Axle Ratio? No sticker...

[JCockerill]

Just Picked up a 06 Diesel dodge 2500 HD. Can anyone tell me how i find out about the rear axle, size, ratio, and limeted slip or not? my fuel mileage has been showing in the 13-15 range, seems low. wanted to see what rear it has. thanks

There should be a sticker in the glove box, or on the inside of the drivers side door

sorry, forgot to mention there is no sticker in the glove box or inside the door jam. . only stickers are for the tire pressures.

Unless it's been changed it probabbly came with a 3:73 ratio and a trak-lock LS, I believe it's called. If you provide a VIN to a dealer they can verify it. The LS in these trucks now is a gear type LS which has been around for years and was orginally refered to as a Tru-track.

Give us a speed and RPM and what gear you are in (also need to know transmission) and I can figure out the ratio, assuming that you have stock tires.
