Engine/Transmission (1998.5 - 2002) 4:10 or 3:73??

[chopperman]

When looking to buy another truck for daily driving and light pulling loads I assume you want the 3:73 rear end gears?? So when looking at the truck how do you tell what gears are in it ? One last question , Can you look in the same place on all the trucks from 01- 05 and find it ? thanks guys as always Brian

Not a good chance to find 3. 73 gears. Stock choices were 3. 55/3. 54 and 4. 10.

Even if you can't find the sticker, there should be a tag on the axle with the ratio on it.

as long as they are stock the sticker/tag can tell you. otherwise assuming its a open diff, put it in neutral, lift one wheel and count driveshaft revolutions against wheel revolutions and divide by two.

Is ratio coded in VIN?

sticker in glove box, tag on diff cover. other than that you're jacking it up and counting revolutions.
