Ford Ranger 4x4 Problems



  • I was wondering if the hubs from ebay fixed your problem. I have a 97 that does the same thing you mentioned, I have automatic hubs, can I change them to manual or should I go back with automatic?
  • I have a 1997 ranger 4x4 with automatic hubs, everything is working on the 4wheel drive, except the hubs are not engaging. can these be changed to manual hubs or should I go back with the automatic hubs. I found some manual hubs on ebay for $265, it comes with a conversion kit to change them over.(not sure if that works) or I can get some rebuilt automatic hubs for $225.
  • I went to the Ford Dealer today . I took my Wife and engaged the 4x4 on the way in. She also noticed the Bump noise. The Mechanic took it on a 15 mile Ride and Could not hear any Problem. Ran a Computer Test on it and said that the 5 & 6 spark plug /wires were showing up on the test.... I said I would Do the Work. I pick up Plugs & Plug Wires. Change out 2 Tonight. 5&6 . Will Change out the Rest Tomorrow. He seem to Think that the Engine was Lugging down when in the 4x4 Mode causing a problem. ?
  • I had a 98 Ranger and it would do the Same Thing. It would Read that it was in 4x4 HI and not engaged. I t was bitter cold out that Winter . No Garage and the Pneumatic part Froze up. When it Thawed out it Worked. I had a Friend who was a Mechanic and Said just get the Hubs that you Manually Lock in / out . Just a Thought.
  • Still working on the 4x4 Problem. Changed out 4 of the 6 Plugs/ Wire so Far ... 2&3 are a Real Bear to Get To. Anyway It Ran smoother but still front end noise only when engaged in 4x4 . Runs Great out of 4 Wheel. ???? III JOHN 2
  • i have a 97 ford ranger when i turn knob nothing happens even the lights on the dash don't light up 4 the 4wd just recently had my bro put a new transfer case motor on still nothing when he had raised the truck the only wheel that spun was the driver side rear he had looked up online about the problem and someone had said about the shift module (located in the dash) we r both rackin r brains about this can someone help i have a feeling i'm just gonna have 2 do a process of elimination
  • I had the same problem with my 02 ranger. It took me 2 years to figure it out with out paying a ton of money to someone. But my problem was the 4x4 control module, located under the passenger side kick panel. Simple to remove kick panel and module(2 screws). Module costed me $180.00 through a friend who works for a dealership. But since I put it in, I have been able to beat the piss out of my truck without worring about getting stuck!!! Extremely happy with my ranger again. I was thinking about getting rid of it due to all the 4x4 problems I have heard about. GOOD LUCK!!!!

    I found your site yesterday and it was useful to me. It helped me hone in on the problem with my ranger. So in appreciation I would like to let others know what I found.
    I have owned my ranger since new, it was in garage at night until last year and the 4X4 worked until 2 months ago. When it failed me I called dealer who said that the shift motor on transfer case was probably bad - cost to replace about $400. After researching this I bought a rebuilt motor, installed it and still had the problem. But by this time, I was suspecting a different problem because sometimes it worked and sometimes it didn't. After reading the threads on this site, and another, I tried disconnecting the battery and resetting the electronics. Still would not work all the time. About a week ago I noticed that it would not work when it was cold but would work after I had driven it for 30 minutes. At first I thought it was the shift motor warming up but I now know it is the control module. I proved this by waiting for it to be cold (less than 40F), seeing that it didn't work then warming the CM with a hair dryer. I took the panel off to expose the CM when I warmed it. Now I am trying to buy the CM off of Ebay. I suspect that some of the other folks who have had problems when it snowed, etc may have the same problem. I also wonder if I have had the problem for awhile but that it didn't show up sooner because the Ranger was in the garage.

    See my previous post. Got new comand module for 4X4 control, 2001 ranger, from Ebay. This fixed my problem. I hope this helps others. It only takes 30 minutes to replace.

    same as all the others, nothing happened when the knob was turned to 4x anything, i took the motor off the transfer case, checked all the mechanical involved and found nothing wrong. after reading a few comments i went and pulled out the fuse(15amp) that went to 4x4 module battery feed(B+). i left it out for about 5 min, while it was out i checked the 10 amp fuse to the 4x4 mod(run/start). nothing wrong- put it back. before i put the 15amp fuse back in, i put the switch to 4x4high and then started the truck, THEN i put the 15amp back in... bam!! finally got my 4x4 back and it was free!!

    I purcahsed a set of manual lockking hubs for a $164.00 from Tellico 4 x 4 and installed them and everything works great. I have to manully change them when I want 4 wheel drive but at least I have 4 wheel drive now
  • Get your 4x4 control module checked. That was my 4x4 problem. Works great now.
  • I have a dilemma. According to my VU meter the voltage making it to my fuel pump is about 8.5 volts compared to the 12.5 volts at the battery. I don't understand where the missing 3.5 volts are going to. I tested the fuel pump it works fine. I checked the fuel interia switch, which is also fine. and I replaced the fuel relay switch under the distribution box located in the engine, just to be safe.

    this really isn't related but the fuel filter was also replaced.

    One day while driving down the road the truck just quit on me... I didn't lose power the pump just stopped pumping. At first I thought I needed a new fuel pump, but like I said it works fine. I'm apparently short on voltage by 3.5 volts.

    Is anybody aware of this problem ever happening and if so what caused it?

    Lots of problems on Rangers with the fuel pump relay. Bad contacts inside might let the pump still work or be dropping some voltage there. The relays are usually beside or inside the fuse box under the hood. There are from 1 to 3 identical relays there. You can swap them around, but a new relay is only about $25.

    You did not take the measurement with the pump running, did you? This might not show total voltage since some would be dropping across the pump when running.

    hi, i have had the EXACT problem! dad was a ford service manager for 35 years..
    he put his best mechanics on it..they heard NOTHING...oasis compute..told them Nothing...! many more knowleageable mechanics, and specialists..still nothing!...finally my dad rode with me and heard it....I test drove with a local mechanic...and sure enough it bogged down after the "thump" sound in the sand...he replaced the engager motorr..This .only made it worse. Afer that, they completely broke down my transfer case and front differential....he could find nothing wrong there!..PLEASE let me know if you were ever successful in getting this fixed...and especially, what was wrong!,, and how they fixed it! this point i would just be happy knowing what has broken!!
  • Hello,
    I ended up Changing the Plugs & Wires out. That seemed to Help. Lugging Down. I haven`t used the 4x4 Since Winter Time. I did try it in the Spring but I was on a Rough Road. I couldn`t Tell. I will have to Check it Again before Winter. I will let you Know soon if it is OK . Have a Great eve.

    if you have auto lockouts on the front axel, that is most likely problem. get manual lockouts and problem should be solved.

    if you have auto locks outs on the front axel, that is moslt likely the problem. the auto ones are infamous for that. install manual lockouts.

    fluid is over filled or you have a plugged filter
