something is wrong with you stuff
it should spin way easer with the hubs unlocked

every jeep and truck I have ever had having the hubs unlocked made a big difference

 

i have a lock right and i can turn everything in the front end by one hub very easily, nothing wrong with it.

one would think amc/chrysler would have had a locking hub option or at least an autolocking hub option if it made such a huge different in gas milage

 

They do make a difference, the reason that they where removed from factory vehicles had to do with cost of building them. And I'd say it's closer to 2-4 mpg savings. Also alot less ware and tare on front end parts...

 

Generally you get 2 mpg

 

huh ok, well can you buy after market brakets to weld to an axle?

 

Yea look into blue torch fab, a to z, ballistic, whatever suits you best. also i think MORE has a kit as well as GenRite

 

Yes you do get about 2mpg better with manual hubs. It's becuase of less drag / friction cuased by having a live axle. When the axle is live the driveshaft is constantly spining cuasing drag, ring gear is turning, shafts, ect. All this is involves work which cost you some mpg. You can save yourself time and money and just take out the front drive shaft to save a little on gas. To me it's not worth buying a new front axle just to save a little gas when you could have used that money to buy the gas its self.

 

Nominated!

 

^that would just about double my current mileage. 33's...stock gears...heavy foot haha

 

i really really doubt you gain any mpg's by having hubs this sounds ridiclous

 

Drive a rig with them. First unlocked than locked. There is a difference and it's more than you'd think...

 

If you want the most bang for your buck and are on a budget. Get a D44 from a fullsize Waggy. It's the same width as your XJ axle at 60". You will have to get brackets and weld them on but, you get a front D44 that you won't break with manual lock out hubs. win win.

 

pretty sure this comes down to ya you get better gas millage in 2wd then 4wd were driving freaking jeeps 1-4 mpg is going to be gone on the trail. if your worryed about the mpg your getting on the pavement your not driving your jeep off road enough.

 

you have no clue what you are talking about
and it not just gas mileage that you are saving
if you have a trail only rig you don't need or want them
but for a multi use vehicle its a big plus

 

It's a plus for a trail only rig also cuase you can use a cheap spool up front and unlock one side to make turns easily
