The modern solid axle and IFS trucks come with unit bearings. While not bad, they are strong and require no service, they force the front wheels to turn the axle shafts, ring/pinion/ and front driveshaft even when in 2 wheel drive. Several manufacturers (my choice was spyntec) make old school hub conversion to allow you to disconnect the front hubs therefor only spinning the wheel/tire, not the whole front end.

The water/meth is a bit of a jump of the gun. Most tuners will require 93 octane for the greatest gains. Here in Cali 93 octane is rare. Running the Water/meth will allow me to run the 93 octane tune while still using 89 octane fuel. Plus the computer will begin to sense the extra fuel over a few cycles and cut back on the injector pulse using less fuel. Hence better MPG.

Keep in mind, none of these mods are cheap (Hubs $1700, Water/Meth $600, Tuner $450), but if you plan to keep your truck for a long time, or plan to lift it (larger wheels and tires) they help you maintain your fuel economy.

Example is I am running 35" Cooper STTs and am getting 12.5mpg mixed daily and 15-17mpg freeway (weather/traffic dependent).


If you look close you can see that my hubs can be locked or set to free

I understand now. I don't know about doing the water/Meth add on. But the Hub conversion sounds like a good idea. I haven't had the power wagon long obiously but your MPG doesn't sound like that great of a improvement over stock?

Its not, but others running 35"s and lifts are running way less than stock.

Thin about it this way. I may only be running 10% better mpg than stock, but others with my tire and lift combination are running 25% less than stock.

Get yourself a good tuner to start. Not only can you open up the power a little you can adjust for tire size, gearing, etc. You can also use it to read and clear trouble codes. Its a good investment.

got a cheap mod for ya (costwise). get some good steel screen. like you use on a screen door or house window screen. attach it to the backside of your grill to keep dirt and debris and bugs from clogging the radiator and other cooling systems. i got my pw used and it took me alot of work to clean out the fins, they were plugged solid and the truck was overheating under normal highway driving. it was the rad being plugged.
also i would remove the cable on the winch and go with a good high quality synthetic rope made for replacing the steel cable. if your gonna do some hard wheeling with lots of big rocks i'd recommend some diff protection plates or bars. they look kinda goofy but i had them on my 97 cherokee and i beat that rig like it owed me money. lol but the diff protection save me more times than i can count. and pw axle housings and diffs aren't cheap. just my 2 cents. and of course the manual hubs would be a good investment as well.
