Are the front axles and drive shaft "engaged" (ie: being turned by the front wheels) while in 2WD?
If so, is it a worthwhile investment, *gas milage wise*, to get a setup that includes manual locking hubs?
TIA
PS: I've just finished my second full tank of gas. The first one I was *trying* to get good milage and got 14.x MPG. (A/C ON most of the time, little highway time.) The second I was lead footing it all the time and got 13.x MPG. (A/C OFF most of the time, a lot more highway time this time.)
I was a bit surprised. I thought I was going to hit single digits :/
I plan on installing a washable air filter (K&N or the one of the other brands now available), and am thinking about replacing the axle/xfr case fluids with "Royal Purple" lube. Anyone have experience with this stuff?
I also found a tire size calc
And, lastly , I've lost my reference to this: My Cherokee is an XJ, right?
(Again, TIA)
