Ford F-150 (2004-2008) :: 4x4 Engaging And Disengaging On 4 Wheel Hi
Apr 29, 2012
My '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 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?

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?

"Sometimes" when I start my car (2015 2.4L GL base) there is a clunk like something is disengaging or engaging i.e., torque converter or transmission.......??

I have an '05 Pathfinder w/ 93k miles. Recently noticed a uneven feel in the power steering, most noticeable at slower (less than 30mph) speeds. Feels like the power steering pump is intermittently engaging/disengaging. As I turn the steering wheel I feel random "tight" or "hard" spots in the steering. Similar to what you would feel if the wheel was against a curb and you were trying to turn into it. Doesn't make any appreciable noise, but can just feel it in the steering wheel.Checked power steering fluid, no issue. Replaced power steering pump, had no effect. Power-flushed the power steering system, had no effect.Oh - and my wife says she hasn't hit any large rocks, logs, or potholes recently!

I 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.

I 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.

2006 F150, SuperCrew with 5.4
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.

Here 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 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 own a 2002 Chev. small blazer with 4 wheel drive available. Largest V-6 available. There is a clunk sound I can hear and feel as this vehicle is shifting OUT of 4 wheel into 2 wheel drive. Going from 2 to 4 wheel drive is perfect. First mechanic (test drove alone) said he would have to tear apart the front transfer case to determine fault. 2nd mechanic (with me along) did power brake slow turns in parking lot. Said the electric shifter was bad and would have to tear apart the transfer case also. Neither mechanic put the vehicle up on a hoist.

I have a 2008 F-150. When moving gear selector from park to either reverse or drive, trans has a delay engaging. After engagement, it runs fine, shifts ok, downshifts ok....

Since new in Jan 04, the trans will disengage, the tach will shoot up and then BANG engages as though I put it in nuetral & then back in drive. Third time to the dealer last Friday and all they want to do is "flash". It did it again as I was leaving the dealer. I have had this happen at 55mph while passing & warmed up but bostly while cold at low speed. 1st or 2nd gear.
I haven't seen any other complaint like this but this is a safety issue.

I have a 2000 F-150 4x4 and the four wheel drive isn't working properly. It does work,but to get it to engage I had to drive in reverse for a couple feet then it locked it and everything was fine,pretty sure that isn't normal. What could be wrong with it? As soon as I turn the lights up on the dash,but the front tires don't spin.

I just got a 99 Ford f150 with the 4.6. I am having problems getting the four wheel drive to engage. I turn the on the dash and the lights come on for four high and for four low. I have a 00 four by four and it works fine, so I know how to work it. In the 99 I can hear the transfer case engaging and everything clicks just fine just like it's going into fourwheel drive, but the front end is not pulling. The front drive shaft is turning but still the front end is not engaged. What the problem may be?

I have a 2005, I purchased new in 2005. I now have around 120,000 miles and have had no problems - just oil changes and new tires.
I was driving on the interstate in MS and all of a sudden all these lights come on on my dash including the triangle that means take it to your dealer immediately. The car sounded funny acted funny and accelerated funny. I was closer to home so I came home and called the dealer. They said to drive it in but if it started acting up to pull over and they would come get me.
When I cranked it, it sounded like I was pushing the accelerator but I wasn't so I cut it off then cranked it again. I drove it very slowly cause it was acting weird.
I drove it home to discuss it with my husband and to do some on-line research here. So 2 - 3 weeks later my husband decides to look at it and by now the little battery is dead - it is the original battery too -btw. So I bought a new toyota battery (the little one). My husband hooked it up to see if the car would crank. It did but all the lights on the dash lite up again including a couple new ones!

My selector switch does not light up when engaging four wheel drive on my 98 f150,could this be my GEM module gone bad ?

My 4 wheel drive is not engaging on a 2001 F150. The indicator lites on the dash illuminate to suggest that the truck is in 4 wheel drive but sigh...it stays in 2 wheel drive. No gross sounds and the indicator lights are not flashing. Could this be a fuse or a relay issue of some sort. What else should I try?
