Help PLEASE - Manual Hub Question

[se7en]

I have a 2000 ford ranger equipped with non vacuum actuated hubs. The truck is continuously getting 10-14 mpg. I'd like to know if I can put manual hubs on the front so I dont have to have everything engaged and spinning constantly.

If anyone knows of a solution to this please provide a link or some more information

Thanks for any help

If you don't have the vacuum hubs then you have a live axle setup so your tires and axles are spinning continuously which would account for about 1 -2 mpg. To put on the manual hubs you are going to have to swap over your front end from the live setup into a hub setup (basically taking the axle shafts, hub assemblies, brakes, ect from a truck equipped with the IFS PVH hubs and put it on your truck.)

theres something else there man than just the hubs. i get 15 city with 4.10s and 33s with my 4.0 the lockung hubs will help but if you getting 10 mpg there might be another issue lurking with your truck

spinning the front shafts constantly only accounts for 1/2 - 3/4 mpg

Because that the loss I see on a TTB 4.0 Ranger

Your CV joints are far less "lossy" in terms of rolling friction, so I doubt you'd see much gain in mileage in exchange for your loss of rolling friction.

IF you are insistant however you can stop spinning the front driveshaft and internal T-case pieces by swapping in the front diff from an explorer that has the Center axle disconnect... that would have you spinning the halfshafts and spider gears, but not the front diff, front driveshaft and T-case chain...

you'll also have to create some method of engaging and disengaging the CAD.

There are a whole collection of damned good reasons why ford gave up on the pulse vacuum hubs.

You can switch over to the 98-00 PVH system by switching your axle shafts and wheel bearings to those from a 98-early00 truck. AVM makes manual hubs that replace the PVH crap.
However, this is still NOT a good system, and the only reason I would recommend it is for installing an aggressive front locker in a truck that gets street use.

BIG NO NO on PVH..

The earlier auto hubs aren't electrical at all, purely mechanical
the electrical part is all in the transfer case.

But you are right in that they didn't work for shit.

"auto hubs" are for people too stupid to lock their hubs before they get into the truck or too lazy to get out and lock them.
