Wheel bearings, dragging brakes, and low tire pressure are the key culprits. I normally get almost 20mpg and ran 8 on my last tank because i have one wheel bearing growling. I have the parts, just haven't had the time to replace it.

"Little" things can make a huge difference.

Gonna grease them inner spindle bearings whilst yer' in there Hoxviii ?

Go for synthetic grease too

Of course. No reason to go that far and not at least look at them. they're only about 8 months old, but since there just really isn't any place to keep a good amount of grease they do tend to dry out prematurely.

I replaced them when I swapped the TTB in, but the wheelbearings are the same ones that were in my red truck when it got wrecked, so they have about 50k on them.

Sounds good Hoxviii

I replaced my original wheel bearings(?) about 5 years ago with American made Timkens. Turned out to be the same price as off shore units anyway.

I remember somebody here mentioning a way to drill for a zerk fitting to fill the area around the inner spindle bearings.

A lot of people

driving any kind of car/truck would kill for even a 10% improvement.

Most of us have Broncos with older plug wires and ignition components. Even the best of us will get at least a 10% improvement with this $140.00 outlay in parts and a half an afternoon's labor.

I have seen a lot of guys get 25%, 50% and 68% better mileage from this trick.

It's getting to the point where the parts required are almost the same price as a tank or two of gasoline.

No question a better Y-pipe and more efficient cat are number two in mileage increases and should be done as soon as the "Sixlitre tune up" has saved you enough gas to afford the Y-pipe.

It took me a year of improvements, but when I started I was getting 11 mpg and when I finished I had hit a record 21.6 mpg.

More importantly I could get 16-19 mpg during every day lead footed driving.

Don't delay do it or order the parts today !
