i have a 2007 ford truck and the 4wd will not engage the lights come on the dash showing 4 low and 4 high and it clunks when you turn the dial to either 4 low or 4 high but does not engage.
View 1 RepliesI have a 2004 F-150 Non Heritage. The 4WD was working fine last year and is not working now. The light on the dash comes on and I do seen to be getting vacuum at the hub but it is not engaging. Several months prior to using the 4WD I did do some front end work and must have knocked the vac line off. It was off for several months, I reinstalled it and it is still not working.
View 2 RepliesI have 08 F150 that the 4x4 is not working on.The light on the dash comes on and I can hear the transfer case engaging.I checked to make sure that I have vacuum to the switch under the hood and that the vacuum line going down to the front diff is holding vacuum.I'm just not sure how it engages the diff.
View 7 RepliesI have read through the folders and many websites on 4x4 problems. My problem has to deal with my four wheel drive not wanting to engage. It has nothing to do with the front end or solenoids. When I put it into 4x4, hi or low it will not send any power to my transfer case motor. It wont even illuminate any lights on the selector switch. I have checked all fuses and replaced any relays that have to do with the 4x4. Where I should go with this?
View 7 RepliesMy '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.

I just replaced the firewall actuator valve for the hubs, and went to try out the 4 wheel drive. The hubs engage and lock to the axle shaft, the transfer case engages and locks to the front driveline, but the front differential isn't doing anything. Is there an actuator for the front or did something break inside?
I have an 06 f150 xlt 4wd 5.4. I bought the truck about two months ago and have come to realize that my 4wd is not working. The light works and you can hear the clunk but recently we got alot of rain and i was going down a georgia clay dirt road and almost got stuck in the middle of the road. i tried 4hi and 4lo but only the rear wheels would spin. I had my wife put it in 4wd while i looked under the truck and the half shafts do turn in 4wd. which doesn't make any sense to me. I also unplugged to vacuum line from the intake and capped it off to try and let the hubs engage that way but still nothing. why would the half shafts be turning but no power to the front wheels in 4wd? does that mean the iwe's are stuck engaged? Which would explain why they turn all the time. But if they are engaged, whether they are stuck or vacuum leak or whatever the reason, shouldn't the front wheels be getting power.
View 8 RepliesHere is my problem: A/C not blowing cold air, blower motor working fine, checked all relevant fuses for A/C and R202 relay under the hood. Everything is fine here. Next, low pressure switch, jumped, clutch does not engage. Next removed relay R202 (clutch relay) measured voltages (at female sockets) where pins 1 and 3 would go, voltage OK. Jumped where pins 3 and 5 would go (bypass to see if clutch engages) and it does. Appears that the pressure switches check out OK (low pressure and A/C cycling switch - although this one not sure). CarMD unit was used as well, and no codes generated so perhaps PCM is working OK? I'm stumped, as a loss of GND by PCM or perhaps a corroded or open wire issue??
Also, possible the A/C switch on the HVAC control could be bad, but the light comes on, (doesn't mean switch is good necessarily). The rest of that unit works fine, control ***** that is, fan speed adjusts properly, air flow looks good. It appears this is an electrical problem where the clutch is not getting juice but I don't know the source of the problem. However, I also noticed that when the clutch/compressor was running (temporarily as described above) cold air still didn't come out. This, I assume, would mean I would need to add refrigerant or re-charge the A/C AFTER I get the clutch to engage electrically. 2004 F-150 5.4L ....
I have a 2005 F-150 with ESOF. When I turn the switch to 4x4 or 4low the lights on the dash will turn on but the front tires will not turn. I checked all the fuses and they were good. I'm not very familiar with this 4x4 system, what the issue is or on how to fix it?
View 3 RepliesI just put a brand new engine in my 2004 f-150 4X4. Truck ran fine for two days. Yesterday I started the truck as usual put it in reverse. As I was backing up it just stopped running no warning nothing just stopped. All electrical still working fine gauges radio etc. When I turn the key I get nothing no starter nothing. The security light continues to flash slowly even when the key is turned on. Basically the best way I can describe it is. The truck is acting like it is in gear when I turn the key. And the odometer reads check gauges.

I recently starting hearing a beeping noise coming from the inside of my car and then i noticed the traction control symbol on my dash. I looked up the symbol in my manual and found it to be the traction control. However, I am not sliding when this is happening. I am just going around a corner, or in 1 case just merging on the highway. I have had this car for several years and it didn't operate this way, so something is definitely wrong.
One additional piece of information - My rack and pinion steering just got replaced in the last couple weeks. However, I called that shop and they told me the two are not related. I'm not sure, so I just thought I would add that piece of information in case it matters.
I am looking to swap 2007 vin 5 to 2008 vin V 5.4. Just wondering what would need to be changer? Would the ECM need to be replaced? I believe the vin V is flex fuel.
View 3 RepliesPump works fine. Replaced pvh. Won't go into 4wd hi or lo no matter what I try. Even with them in lock. How do I know if hubs need replaced or just hub locks?
View 2 RepliesI'm trying to figure out why my auto locking hubs do not engage. To isolate the problem shouldn't the hub engage if a vacuum is applied to that hub only? A solid 18 inHg is maintained at that hub for over 10 minutes but the selector will not rotate, which suggests to me the seals are OK. What then might be the problem?
View 13 RepliesI am thinking about rewiring the fog lights on my 07 f150 to run some off road lights. Do the wiring can handle two 6" lights? Not sure of the wattage yet for the lights....
View 2 RepliesI have a 2007 F150 (2wd) with 80k. My truck recently was vibrating under braking so i took it to my mechanic to have the brakes fixed. All the rotors needed to be replaced. In doing so, the front rotors were changed out with the kit that converts the front rotor/bearing assembly into two separate pieces to cut down on maintenance costs in the future. With this being said, after getting this work done, the truck didn't vibrate anymore... that is until i got it out on the highway. Now the truck vibrates from about 45-50 and 70-80 pretty bad. The steering wheel shakes back and forth too. I have gotten the tires balanced in hopes to fix this problem which it didnt. What could this problem be?
View 4 RepliesSo last night my trans have out, going up a slight grade, all of a sudden the engine revved and I had no more 3rd gear. I've done some research, looks like rebuilding it is the only option. I've got my Mustang GT to drive in the meantime, so I am thinking of rebuilding it myself. The truck is an '07 F150 5.4 2WD.
View 7 Repliesi have a 2007 F150 Fx4, with 94,000 miles. When I hit the speed of around 40-45 and I step on the gas it starts to chug until I press harder down the it gets out and runs just fine. The thing that confuses me is it doesn't always do it. Id say about 3 times a week. I am replacing my fuel filter tomorrow. I purchased this truck with 85k on it, and this just started happening. The spark plugs have never been changed. And am thinking about taking it in to get those done too. I also tested all my injectors and they are all working. No codes have been thrown either.
View 6 RepliesI have a bit of a question about my 2007 Ford F-150 w/ the 5.4 3V. I don't know how long it's been doing this, I just happened to notice it not long ago. Whenever I rev the truck (doesn't matter if it's in Park or Drive) in between 800-1,000 RPMs it makes a "rattle" type sound - like a "rat-tat-tat-tat" I guess is one way of putting it. It only does it when the engine is hot, it won't do it when it cools down some. The truck has 63,000 miles and I've always ran the recommended 5W-20 weight oil. Engine runs good, no power-loss or anything like that. I have posted a video on YouTube of the sound. If you want to skip my talking in the video to get to the sound, then skip to 1 minute and 40 seconds of the video.

My truck has been jolting lately around 40-50mph. I have done some research, and I believe its one of the coils going out or is out. The problem is I can't get it to throw the ck engine light. So it's making it hard to determine which coil is actually bad. What to do? I honestly dont want to spend the money replacing every coil at this point.
