2008 5.4L triton. When I'm in the snow or mud and engage the 4 wheel drive I hit the gas and I can hear what I think it is the hub spinning but it will not turn the wheel. Hoping it is not my transfer case...
View 3 RepliesI have a 2005 F150 5.4 with the 3.55 LS rear end. I just changed the diff fluid to Lucas 75W140 synthetic and added 4 oz of Motorcraft friction modifier. The gears looked great when I had the cover off. But now my truck only seems to want to spin one tire. It was on a ice covered road so it shouldn't be that one tire was catching more traction than the other. Could a simple oil change cause the limited slip to stop working?
View 4 RepliesWhenever I am driving 60 km/h or more a loud noise seems to come into play. The noise sounds like a really loose ball bearing spinning. Then sounds like a turbine slowing down when going 30 or under. The only issue is the noise does not go away until the truck shifts down into 1st gear. And when doing so the truck jerks enough for everyone in the vechile to feel it. This problem only seems to come when it's rainy or slushy outside and even then does not happen very often. I have had the truck to ford and another mech. Nobody can seem to pinpoint the problem. 2006 f150 5.4l ....

View 1 RepliesTruck shifts great from 2 to 4h to 4l and back to 2. However, at random times - any speed - usually when slowing down - I hear/feel something engage and there is usually a ratchet sound. I figured out its the 4x4 - if I switch to 4h then back to 2 quick, it stops. What the heck.

View 3 RepliesFor the last little while I have been having an issue with the 4wd in my 2006 F-150 with about 93k on the clock. Sometimes it would engage when I switched to 4H/4L and other times it wouldn't. A friend of mine works at a Ford dealership and said it could be the vacuum solenoid on the firewall going bad. So I bought a new one and as I removed the old one, noticed debris in one of the inlets. So I cleaned that out and neither old or new solved the problem. Then I went through ALL of the vacuum lines and found some debris in parts of them....
Cleaned them all out and still nothing. Then I got to thinking it may be the ESOF motor on the transfer case. Checked to make sure there was power to the plug, which there was. Removed the motor and turned switch, and the motor seemed to be working. Reattached the motor and the 4wd would engage/disengage without problem. Pretty much everywhere I went I would check it and it worked fine . Then all of a sudden it didn't . So I took the motor off, turned selector and it worked fine. No issues yesterday at all.
So, I am not sure if it is the motor going bad or not. Could there be a contact problem? I talked to a mechanic this morning and he told me to drive around with it in 4H for a while because more times than not it doesn't get used enough. I'm just not sure what could be going on...am I missing something?
I have a 2007 ford f150 and the 4wd will not engage at all checked vacuum lines they all look intact wondering if it could be the IWE solenoid and is there any way to test the IWE solenoid ...
View 5 RepliesI have a 2005 f150 and it will not engage the front hubs. It is a manual shift on the fly not electric. I have done some checking and this is what i have found so far. Pull the lever into 4H, dash light comes on, IWE's do not lock onto axle. Same for 4L. The transfer case does come in when lever is pulled into either 4H or 4L. Front end up on jack stands, engine off. Turn either wheel and axle turns with it as it should. Start engine, turn either wheel and it is free from axle, as it should be. so there is vacuum going to IWE when engine is on. Not sure what to check next. Is the vacuum solenoid on the firewall bad?? Is there something not getting activated when i pull the floor lever back?

Running down the road at 44-MPH. Pulling 5,000lbs. Engine died just after turning on the air conditioner. (Not sure this is relevant.)
Would not start. Turned the key - the starter would engage, but the engine would only turn maybe a quarter turn. Try it again engine turns. Try it again and now it only clicks. So, I
-Replaced the battery. Same symptom. Will only turn the engine 1/4 turn.
-Replaced the starter. Same symptom.
-Checked oil. Clean. No Water. No gas smell. (200 miles since last oil change)
-Checked coolant. Clean. No Oil.
-Charged the new battery and tried again. Same symptom.
-Checked and cleaned all grounds and battery cables. Same symptom.
-Checked that the transmission is shifting though the gears. Seems fine.
-Removed serpentine belt. Check all pulleys, and accessories that are driven by the belt. Everything spins quietly and freely.
-I put the truck in neutral and tried to spin the crank pulley with a 2 breaker bar. It wouldn't budge.
Am I missing something? I fear the engine is seized or hydro-locked. If hydro-locked, wouldn't I see signs in the fluids? Can the pistons be hydrolocked with fuel? Not sure what to try next.
2006 Lariat 4x4 Troubleshooting. My front wheels wont engage when I select 4H or 4L. No dash lights are ever lit.
I read up and understand how the system works and plan to replace the solenoid, transfer case motor and both hub actuators. I swapped out the solenoid and wanted to test that it was functioning properly so I followed the video below:
YouTube........
With the engine running and selector switch at 2WD, I pull the vacuum lines off and can feel vacuum at the supply. I then hook up just the supply line up (to the bottom port) and expect to feel vacuum at the other solenoid port (top port - what I would call the outlet) and cannot feel any vacuum.
This has halted my repair attempts as I am not convinced this is functioning and would pull in the actuators if they were functional. I know it's a small vacuum from a small orifice but I would think I should feel it by hand, no?
The solenoid's electrical connector is plugged in during this as well. I get the same performance with the old solenoid and the new. If I bypass the solenoid I can feel vacuum at the front wheel hubs.
Should I try a third solenoid? Seems unlikely I would have 2 bad ones...No OBDII codes at all. What to try next?
I have a 2005 F150 113,000 FX4. When I put the truck into 4x4 high the light comes on and the front driveshaft engages. Same with 4x4 low. the problem is that the hubs never actually lock. When I move forward in some mud or wet grass the right front hub makes this grinding noise like it is actually trying to engage but never does. Same with 4x4 low. I do not have any weird noises when I drive in 2wd.
View 6 RepliesI have an automatic 2004 f150 fx4 with a 5.4 engine. I just bought the truck and noticed the other day that when I shift into reverse, there is a 1-2 second delay. Sometimes it will shift quicker than other times. Drive seems to be a little more swift I think. Everything seems to run smooth and the shifting is very smoot other than the delay. Is this normal or what could be some of the causes. The previous owner has the ATF changed this pst summer and it looks and smells fine other than maybe having to much fluid.
View 2 RepliesI have a problem transfer case 2006 f-150 , it tries to engage once in a while as I am driving and makes a terrible noise . I pulled the vacuum lines off at the hubs on each front hub and it stopped trying to engage. What the problem could be ?
View 1 RepliesI have a 2004 FX4 4x4 ... Four wheel drive is not working!!!!! Turn the dash switch to 4High or 4Low and the lights come on in my dash gauge cluster. So my 4x4 lights come on as if the 4x4 is working but my front wheels do not turn. What I have done:
Drove the truck forward while I watched the front drive shaft going from the transfer case to the front differential. Did this in 2WD and then in 4WD high. While driving forward in 2WD the front drive shaft did not move. Once put into 4WD high and driven forward the front drive shaft was turning. I guess this tells me that my transfer case and shift motor are working?
I jacked up my driver side front wheel and turned the tire by hand while the truck was running in 2WD. The tire spun freely and the CV axle (half shaft) did not turn. Then turned 4x4 dash switch to 4WD high and turned the tire again by hand and the CV axle turned while turning the tire. I guess this indicates that the IWE actuator was working....I guess???
Repeated the process above for the front passenger side of the truck and the tire would always spin freely regardless if in 2WD or 4WD. I could not get the CV axle to turn while spinning the tire on the passenger side when the truck was running and switched to 4WD
I checked the vacuum solenoid near the battery mounted on the firewall. The vacuum line supplying vacuum to solenoid was working and pulling vacuum. I did a series of test in conjunction with the dashboard 4x4 selector and the Vacuum Solenoid seemed to be working properly.
Crawled under the truck while the engine was running and pulled the vacuum line off the nipples of each IWE Actuators (drive and passenger side) put my finger over the lines and felt decent vacuum at each end of each vacuum line.
So dash switch and 4x4 light works stays on solid and bright does not flicker
Vacuum solenoid and vacuum lines seem to be working
Transfer case and shift motor seem to be working
Driver side IWE actuator seems to work
Front passenger side Actuator does not seem to be working??? Why I am so confused about this is because in HOURS of Internet research it seems that this Actuator is not allowed to engage by vacuum pressure. When I disconnect the vacuum line to the passenger side actuator I expected to hub to lock, but it did not, the tire would turn but the CV axle wouldn't? If I replace the passenger side IWE actuator will this fix my four wheel drive? Or is there something else I am missing??
Have 2005 F150 5.4L 4WD Unit is trying to engage on all left hand curves and occasionally on straightaways, it has been doing this for about 1 month on left hand curves but just the last week on straightaways when it does it on straights you almost have to stop the tuck before it quits, has 70,000 miles and never been abused.
View 1 RepliesJust recently replaced the driver side 4wd actuator. When testing the system to see if it was working, I noticed that in 2wd everything seemed to be in order (wheel spun without the half shaft, no grinding noises on test drive, seemed good to go).
However, when I switched to 4hi, the dash light "4HI" would come on but the wheel still spun freely without the half shaft. When the truck was off, the wheel and half shaft spun together as they should when vacuum is released from the actuator. When I switched to 4lo, the dash light did not come on and the check engine light came on. Pulling codes revealed P0171 and P0174.
Could these codes be caused by a bad solenoid? Is the solenoid not switching the vacuum off and that's my issue? Are there other possibilities?
had issue/backed into garage door with rear of car---car will now not go into gear--gear shift will not engage. can manually engage with button, but, will not do normally. abs break system light now on. what do I do?
View 2 RepliesI have noticed that my 2008 Prius does not always engage EV mode (after I push the EV button) when the battery is green (nearly fully charged) and speed is well below 45 km/hr. Message displayed is "switching to EV mode is invalid now". So it seems there are factors at play other than the speed and the level of traction battery charge.
What these are? Is battery temperature monitored? Will the operation of the air conditioner affect it? Most times it doesn't but I wonder if under certain circumstances it might.
I use it at times if I am going up a slow speed incline, often from a standing start, knowing that there will be plenty of opportunity to recharge shortly after.
Weather here is pretty warm- around 30C maximum during the day.
I have a 2008 F250 XLT. When i am driving and turn the wheel a squeak is noticeable while the tire is spinning. as i speed up the squeak gets faster and slower when i slow down. I have it narrowed down to the right front tire but cant figure out what is causing it.
