The place to be careful is if you swap gears on a 2002-2005. The wheel speed sensor in the rear is upstream of the rear diff on those years. A change in gearing would make the powertrain control module think the tires are spinning at different speeds. This means ABS may kick in, traction control will kick in, and the transfer case will probably have issues.
I have a 2005, and have seriously been looking into 3.73 or 3.90 gearing, are you saying because I am an 05 this is gona cause me nothing but problems?
