    Or you might have failing, failed, CV joint.

    This is my 1st time driving my 2004 Ford Explorer in the snow. I went to put in into 4 wheel drive this morning and there are no lights or anything that goes on my dash to let me know that i am in 4 wheel drive?? IS this normal?

    NO, it's not normal. Your 4WD isn't engaging, most likely the shift motor on the transfer case is stuck or no longer working. It's about a $400 repair, but fairly simple to do. Very common failure on aging Explorers.
  • this may a little too late but your brobleem is a sensor on the back of the transfer case. you have to remove the 4wheel drive motor and then the 2 sensors I got mine from a junkyard for less than $10. it is an easy fix. good luck.
  • On below freezing mornings I will try to start my ford explorer and when I turn the key it barely wants to crank. a couple of trys later and all it dose is crank until the battery dosent let it anymore. so I put cables to it from my wifes car and keep trying. In order for it to start I have to pump the gas peddal until it starts. After this ordeal which has taken almost an hour it will start the rest of the day with no problem. Just wanted to know if it could be the starter or the fuel supply? Can someone help? Thanks.

    It sounds more like the battery than the starter. It's possible that the starter is worn out and is pulling too much current from the battery, yet not spinning fast enough to start the engine, but cold temperature in the morning decreases the cold-cranking amps a battery has to begin with. If it's weak, it'll do what you're describing every time. As it warms up during the day, it would naturally do better. I would replace the battery first.
  • I have replaced the 4wd computer, the motor for the 4wd, but the lights still dont even tell me if its on 2wd or 4wd and the 4wd dont work?

    I have a 2003 Ford Explorer that has trouble getting into 4 wheel drive in the snow/rain. It will slip when accelerating in snow. Most issues are accelerating from low speeds but it has slipped going as fast as 60 MPH on a rainy day. This may have led to transmission failure, just replaced my transmission so I want to get to the root of this before it snows again. Until reading posts on here I honestly didn't even know there was a 4x4 light so I guess that does not come on ever.

    Thanks in advance for any advice!

    Starter commutator brushes are to worn, $4.00 DIY repair. Poor or low battery and the starter solenoid would be clicking in and out.
  • When I hit 56 mph or there about, my Ford Explorer misses/jerks. It's when you accelerate to 60 mph, it's when you drop speed at 56 mph or so, it misses. It also does it somewhere in the 40mph range (the exact same speed). Any idea what's causing this or what to do to fix it?
  • nvbankernvbanker Posts: 7,285
    Doesn't sound like the engine - it should be RPM sensitive, not speed sensitive. That leaves Transmission. Any idea which gear it's in when it does that? Could be a clutch issue between 4th and 5th (overdrive)...

    wwest? Any ideas?

    I've seem failed motor mounts cause that effect. Our '95 LS400 exhibited those same symptoms due to loose rear diff'l mounts/cushions
  • UPDATE: It's basically a bump or it feels like an engine miss but we've determined it's not an engine miss. We unplugged the 4WD actuator on the transfer case and it stopped doing it. Could it be a wheel sensor or a selector switch? It does it in 4WD automatic. When we unplug the 4WD actuator, it doesn't do it.
  • wwestwwest Posts: 10,706
    Check the rear diff'l, motor, and transaxle mounts. If the motor or diff'l is able to rotate in it's mounts even slightly during acceleration or decel the transaxle vehicle speed sensor will give momentary eroneous speed readings causing the transaxle to shift in and/or out of lock-up.

    On the other hand at ~40MPH the "auto" 4WD system should NOT be engaged, perhaps that is part of the problem.

    Since the 4X4 spline/dog clutch cannot possibly be used how is 4WD "automatic" implemented in an '04 Explorer...?
  • Im have 4x4 issues. When i bought it it wouldn't go in to 4hi or 4low and no lights when you turned the knob to eachone. I changed the electric motor and volia i have 4hi and 4low lights..... but the front wheels they do not turn.... this is my issue i dont think its the transfer case because i can feel it shift into low when i turn it to 4low.....i also noticed while in 4hi if you tromp on it i feel a cluck or jerk like its slipping in and out of 4x4.....any suggestions? Would the TOD (torque on demand) relay have something to do with this? And another thing does anyone know how the front wheels lock up, does it have locking hubs or is it in the front axle?

    You need to take your Exploder to an EXPERT R/awd/4WD/4X4 mechanic/technician for repair, possibly, but most certainly for a detailed TUTORIAL on the subject at hand.
  • I've seen this on an 04 F-150. Using the tach, check the RPM at 56 MPH. Now find a section of road where you can hold it in 1st gear and do a very gradual accel through that RPM point. (Not too fast or you'll drive right through it.) If the miss occurs at that RPM then you may have an issue with the Crank Position Sensor (CKP) wiring.
    There's a variable reluctance sensor. and it is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft . The sine wave output is via a twisted pair, but if one wire is open or grounded then a miss will occur due to the designed CKP software edge transition.
    At low speed it reads all tooth edges, but as speed increases it has to shift to counting every other edge. The software designer picks an optimal transition RPM, and all is good unless one CKP wire fails. Then the PCM goes through a momentary reset which ends up as a miss.
    It usually won't hurt the vehicle, it's just annoying when you drive at that point. Look for pinched or corroded wiring between the PCM and CKP sensor.

    Again, your expertise is respected and valued, but your insult to owners by calling their truck an "exploder" is not appreciated nor respected. Must you? The visitors here may have a problem, may not even be happy, but it's their car. They chose it, they own it. And they may like it. I've had 8 of 'em. Some were better (140,000 trouble free miles) than others (65,000 trouble free miles), but I do love the superior design of them since inception. Which is why I'm on my 8th one.

    I have pretty much zero respect for GM, but I don't insult the owners.
