2000 Ford Ranger:
Body Style: SUPER CAB PICKUP
Engine: 3.0L V6 EFI FLEX FUEL
Drive line: 4 WHEEL DRIVE
Brakes: 4wd anti-lock brake system
Odometer: 106,000
I've had this vehicle for 2 years and have been pleased with its performance--when the wheels don't lockup occasionally--after sitting overnight. The incidents in the past happened about 6 times over the first 18 months, but are more frequent now.
During one episode this winter, the rear and/or front wheels on the driver's side would spin on the ice--depending whether is was in 2 or 4w drive--but the passenger side wheels would not turn at all. The low range 4wd light remained on in this case, even when I switched to 4wd high, then 2wd high (I had parked it the night before in 4wd low-range).
We jacked up the passenger side to try and manually rotate the front wheel...barely moved and the front drivetrain and axles budged with the wheel movement. The engine was off, the transmission in neutral, the setting at 2wd, and the parking brake off. After we pondered our options for an hour, we removed the jack, out of curiousity, started up the truck and backed up with no problem! Did we manually unlock some problem? Locked auto hubs?
Last Monday, I took the extra precaution to take the truck out of 4wd and into 2wd high range, back it up about 20 feet, go forward again, then kill the engine and set the parking brake. To my dismay, I found the truck locked up again this Wednesday morning. We had one of our typical snowstorms that dropped the temperature from 70 degrees on Sunday to the low 20's on Monday when I ran the truck into town in 4wd, high.
I was ready to check the fuses after leaving the truck in the sunshine for 5 hours, but decided to see if it'd move first. It did!
my front hubs wont connect. when i shift into 4X4 high or 4X4 low you can feel the the transfer case hooking up but the front wheels wont pull.
anybody have any ideas about what could be wrong

Well I got the above problem fixed. After Taking off the shift motor and taking it apart I found out that the Electric motor had water leak into it from the "O" ring between the motor and gear housing,Thus causing the armature and magnets to rust together,siezing it up.So after getting it apart and getting all the rust off and getting it all cleaned up then applying some waterproof marine grease to the unit,and then sealing with RTV high temp black silicone adhesive where the housing come together.along with sealing any place that might leak inside and out,I put the motor back on the truck and it works as good as new now.
good luck,
Kevin
Now it will not go into 4 wheel drive(hi or lo).The lights on the dash light up when it is started,they work when you turn the switch from 2 wheel drive to 4 hi and lo,but the eletric shift motor doesn't turn.
I installed a new electric shift motor,but it doesn't do anything either.There was a wire from the transfer case to the old shift motor.I stripped the wire on the plug going up thru the floor (black I think) and still nothing.
What else can I try now.
Thanks for any help.

I checked the fuses in the cab and under the hood,all looked fine.

Start the truck, both 4x4 indicators come on momentarily, then go out. no response from the switch at all, no indicators come on when switched to 4hi or 4lo. fuse in dash good for 4x4, as is 20amp under the hood. checked for power at motor-nothing in any switch position. removed motor, supplied power, works in both directions with no trouble. Disconnected battery to power down and "reset" the 4x4 module.....still nothing. anyone have any wiring diagrams on how this system works? I'm wondering if the sensor/contac ring on the motor is bad, but need to know how to check it. Hate to buy either a motor or a module and not be able to return them! any help greatly appreciated!
You only need to lock them in when you want 4x4 and you will still need to use the switch on the dash to engage 4 wheel hi and 4 wheel lo.
I know that when you shift it into 4x4 the transfer case motor engauges the transfer case, which in turn locks the front drive shaft..
Now here is were I am lost, The front shaft is locked in,but I can still turn the CV's and the wheels spin free when holding the CV's. I have vacume to the Hub's. Now do the hub's have anything to do with the Front diff locking in and powering the front wheels,or should the front diff be locked in and the (CV's can't spin) with the front shaft when in 4wd.
How does/is the front diff engauged ?
I lifted the whole vehicle in the air, started the truck , put it into 4wd and everything turned with the exception of the wheels. But when I put the vehicle down and locked into 4wd the driveshaft is locked in and turns but the Cvs/front axles can spin free
I worked on an '01 which has Ford's latest setup (cv front axles with no disconnect other than the t-case) My parents had a '94 with auto locking mechanical hubs (still different from yours). You have managed to get a model year with what i would consider (and many, many others!) to be Ford's worst idea! (SORRY, but its true!) Here's what i found on your system:
Your hubs are called Pulse Vaccuum Hubs (PVH) and are found on model years '98-'00. Basically vaccuum is supplied to each of the front hubs, which locks them in. They work off a vacuum pump which is supposedly located under your air filter box. Check to make sure it is working; if it appears like its working go on to the vacuum line(s)? that lead to the front axle from the pump and check for any leakage. Next check the front hubs. The locking hubs are the black caps in the center of each from wheel ..they snap on and off..(hard to take off without breaking a few tabs, so be careful)..There are seals on these hubs, one or both may not be holding the vacuum created by the pump. If you have a leak anywhere, the hubs are rendered useless. Best bet is to replace with manual locking hubs or this will be a continuous headache. Search AVM hubs on the net, you’ll be able to find Manual lockouts for it.
