I've got a lifted 2006 F150 crew cab lariat and I understand mileage is poor 10-11 per mile. 35" tires under a pro comp 6" lift. I have changed out my plugs twice last year and am still very under powered. What else can i do? I also have a clunk when i accelerate, sound like the rear end or drive line possibly. Had my transfer case replaced recently by ford and don't remember the noise prior.
View 11 RepliesI drive a 2006 F-150. I'm new to the forum and already found some good info on the annoying tick coming from my 5.4.
I have recently purchased a ski boat and lately when towing my boat and coming to a stop I feel as light movement coming from the rear of the truck that feels like something slides forward slightly. When I accelerate "it" slides back and if I accelerate quickly, "it" makes a loud clank noise.
I have ruled out hitch, receiver, ball, anything from the boat/trailer etc... It is coming from the transfer case/ spare tire area under the truck and it only appears to do it (or to where it is noticeable) while towing the boat.

View 5 RepliesIve got a 04 f350 that after u shift into 4hi or 4lo when u accelerate it it makes loud clunk noise in fwd or reverse hi or lo. With hubs unlocked it still clunks. Have checked, wheel bearings, axle U-joints, and driveshaft joints all good. So I am thinking I've got issues in t-case. Popped drain plug out and wow that dex merc 4 looks nasty. So thinking I need exploded view of transfer case.
View 4 RepliesI have a 04 4.6 f150 4x4. I have had some off road wear on the truck but put a stop to it here recently. I have replaced ball joints , struts , sway bar linkage , hubs , and now have a clunking sound going over every bump no matter the speed. Everything is tight underneath while stopped, other than the front driveshaft. It seems to have too much play to me? What it could be ???
View 8 RepliesWell this weekend I'm doing quite a bit of work to the truck. My tires and exhaust got delivered last night, now I'm just waiting on the leveling kit. Here's my issue:
For a little while now (5k-ish miles) going in and out of overdrive the tranny makes a clunk noise during the shift. Time to change the tranny fluid and filter? I am making a trip up north on Sunday and don't want to have the tranny the bed on the way.
On saturday I am doing the leveling kit (2"), brakes, exhaust (MBRP), and new tires (325/60r20 Terra Grapplers). Should I go ahead and do the tranny fluid and filter while I'm at it, or just wait till I get back. I am figuring on about 2k miles throughout the trip.
Yesterday my 5 year old daughter was "driving" my 07 S-cab 4x4 while I was installing steps on the rocker panels. (yes the engine was off and E-brake on). Anyways as she was steering rapidly from R-to L ther is a noticeable steel-to-steel banging coming from the box area. I could feel it too in the steering.
I started the engine, and steer R-to L, and no more clunk. Shut it down and there it is again. It goes down the road very nicely with no issues. Is this a "normal" situation, A "clunk,, clunk, clunk" when steering back and forth with the engine off, or is something need attention?
Have a 2004 Fx4. Lately its been shaking violently when i accelerate. When I turn the overdrive off it stops.
View 9 RepliesI have a 2004 f150 4x4, When I put it in four wheel drive everything fine until I make a sharp turn. It's not a little wheel hop its a loud clunk that feels like the tire comes off the ground. I changed the cv axle from the side that seemed to be doing it but it didn't work. Could it be the actuator?
View 1 RepliesAs I said when I take off from a dead stop I can feel a clunk or a bump that feels like it is coming from the rear wheels. I can feel it more than I can hear it, although I can hear it a little. It is difficult to describe this. It is only for a second and kinda feels like the rear wheels have no traction then it bumps and takes off. If I ease into the accelerator I can avoid it, but I don't have to hit it real hard at all to get it to do it. I am sure it is not u-joints as I put a brand new drive shaft from driveshaft specialist on in the spring.
View 3 RepliesMy 2005 150 4X4 made a "clunk" noises several times when in 4 wheel this last weekend.
Sounded like the transfer case wasn't fully engaged.
This was after doing numerous 3 point turns on a dead end road to turn around. A real nightmare, cliffs on one side mountain on the other.
when we got back to relativity flat ground it ran fine with no more "clunking" noises.
It has 95K of hard miles on it. We didn't want to get stuck out of cell phone range, so we headed home.
This morning as I was driving to work, my truck hesitated as I tried to accelerate from a stop sign. I pressed the pedal and nothing, almost felt like it was going to stall. After about 3 seconds it started driving again and I had no further issues. It seems to only do this in the morning when it is cold. It has done this a couple of times before, but usually it recovers almost immediately. I had no CEL come on. 2007 F150.....
View 1 RepliesMy f-150 has an intermittent rough idle and consistently runs rough when you accelerate quickly. Vehicle is not throwing any codes?

I have cleared these codes and reset the main computer the truck barely starts and will not accelerate...could the spark plugs be an issue...
Well I have had a completely dependable truck until today. I was driving my truck on the way home, its an FX4 with only 33K miles on it that i have had since new. I went to accelerate to pass some cyclists (not a hard acceleration) and the vehicle cut off seemed like it kind of bucked a little as if it was shifting gears hard. I got a service light but what was weird was the gauges worked and the RPM still showed 1000. I did have power still though as the radio was on. The only thing that is currently wrong with the vehicle is the odometer gauge is out and needs to be replaced.
Anyway I shifted to neutral and restarted on the fly and than shifted back into drive and it drove the rest of the way home fine. After i got it to my neighborhood i ran it hard and it did not cut off again. I do not want this vehicle to cut out of me in town in the middle of traffic or while i am driving my 18 month old around and i get disabled with her in the truck. Slug of water maybe? I filled up on monday and still have around 3/4 of a tank of gas. Maybe short because of the gauge issue getting worse? I have the crazy door locks and beeps but nothing else has occurred. 05 F150 FX4 5.4 ....
I just bought a used '05 F-150 and recently I noticed more a shaking I guess you'd call it. When I start from 0 to 80 nothing seems wrong, but when I slow down to coasting like 40 - 45mph and accelerate to 50 - 55 mph it shakes or acts like its having a hard time shifting or its skipping. And it doesn't happen till after I go past 40-55mph range and I've tried it in overdrive and out of it.
View 3 RepliesWife was driving 2008 w/70k miles, powered off completely in middle of street, coasted into parking lot. No warnings or lights on dash. Unable to shift to park. Won't power on to acc mode even. Interior lights etc work fine. Battery measures 13.6, 14.2 at front terminals? Slight burning smell from engine compartment possibly right side. Disconnected battery for hard reboot, no change. Unable to read codes as won't power on.
View 19 Replies2006 F150 FX4 5.4L, 118k miles... At highway speeds (45-50) and (55-60) as I am slightly accelerating it feels like the transmission or maybe ignition system is skipping a beat. Kind of feels like a small bump. I replaced spark plugs with motocraft about 35K miles ago and recently all transmission fluid via cooler line. Had some concerns about system flush so I just drained and refilled entire system via cooler lines. I have read that it could be my COP's ...
View 7 RepliesI picked up my 2005 F150 4x4 last winter. It has 135k miles & a slight tranny problem.
When cruising around 45 mph - right between where it wants to be in top gear or not - if I slightly accelerate the trans BANGS between the two gears.
I mean repeatedly bangs - it is not a smooth shift where it can't decide which gear to use - it is a hard BANG where it can't decide which gear to be in.
What gives? I can usually stop it if I turn on the towing button - shutting off high gear.
When I accelerate from a dead stop I have this squeaking that comes from the back of the truck that goes away after a few seconds. Then when I get up to about 50mph I have this really annoying vibration. Its not a real heavy vibration but it is there. I am thinking it could be the universal joints, am I way off here or what?
View 6 RepliesI bought a 2005 F150 supercrew w/ 5.4 Triton engine brand new. It now has 16000 miles on it and all was well until...
I was driving to work 2 days ago and all of a sudden my truck started acting all weird. I couldn't accelerate and it seemed as though I was driving over rumble strips. I went directly to the garage and they told me that 2 fuel injectors mal-functioned and that flooded everything with gas. I needed 2 injectors and 8 spark plugs. The next day the garage called and said that they replaced the parts but now there is a terrible knocking noise and that I needed a new engine.
I am not a car wiz so what other things should I be aware of? What other questions should I be asking?
