Question.
Okay, so this is starting to make my head hurt... JK it was already hurting.
At this point I'm not sure exactly what it is that you are working with or asking. I'm going to try to help you out a bit though.
So on my ranger my driverside locking hub is broken but my passenger side is just fine
What do you mean by your driver side is broken and how do you know that your passenger side is just fine? Is the driver side physically damaged or is it just not working?
does that mean that when i engage the 4x4 im technically usinf 3x3?
Actually no, that would be a 3x4 as long as all 4 tires are still on the truck, which I'm kinda wondering about at this point. Seriously though, due to the way that everything functions, at this point it's probably not even a 2x4.
What you need to understand is that on most axles have an open differential and do not send power to both wheels. An open differential naturally sends all power to the wheel with the least traction, that's why you get a "one wheel peel" when trying to spin tires. Some axles get a locker or limited slip device installed in the differential which transfers power to both wheels evenly (locker) or to the opposite wheel when slippage is detected (limited slip).
I don't know if your truck is open or limited slip rear differential, but so far as I am aware every 4wd Ranger left the factory with an open front differential. What does this mean to you? With the removed/broken front driver side locking hub removed, the front driver side axle shaft shows no traction, therefore when you put the truck into 4wd all power to the front end is being sent to the driver side. What that means to you is that at the moment your truck is at most a 2wd
IF you have a limited slip rear axle.
If so what if i lock the driverside manualy woyld it work? The locking hub on my driverside will not lock or anything so i took it out and i was thinkibg if i was to put it back and just manually lock it would it work.
First off, why do you think that the driverside hub will not lock?
How do you plan to lock it manually? If buying the aftermarket locking hubs, they come as a pair one for each side, so no point in installing just the one.
There are two mods that can make the factory hubs either permanently locked or manually lockable, but they are band-aid solutions at best. Before trying either one I'd suggest doing some more troubleshooting and making sure that the hub is bad. Usually PVH hub (factory hub) problems are caused not by the hub itself, but by a vacuum leak either in the lines or a seal in the front steering knuckle. If you still have issues after the trouble shooting, procedures for either mod (and troubleshooting) can be found in the tech library.
