Check the axel code Its on a tag on the rear end and inside the drivers door

All it says on the inside of the door for axle is D4?? Does anyone know how 4:10 gears are on the highway?? Whats the top speed?? Do you also have to change the front axle gears too???

You have a limited slip 3.73

Yes, if you have 4x4 (and still want to use it) you need to change the gears in both differentials. 3.73s are a good middle-ground gear for stock tires. No use going to 4.10s, not enough difference for the money.
