The whole vehicle vibrates and shudders at highway speed with now warning. It now feels as if the rear axle in moving, give an odd sensation when applying the gas pedal or taking your foot off the gas pedal. I am a technician by trade, so I put the truck up on the lift at my shop and have noticed the pinion in the rear differential has significant up and down movement. After researching a bit, it seems the pinion and ring gear gall themselves, I'm not sure if the pinion bearing failed causing this. Or if the ring and pinion failed causing the bearing to fail. At any rate there seems to be a lot of individuals with my experience, a quick search online may provide a scope of the issue.

Takata recall.
With my foot on the brake, I put the truck in reverse to begin backing out of a driveway. I applied a little gas to slowly backup around the turn in the drive. As I was rolling backwards, I had my foot on the brake because I was navigating past other parked vehicles. As I was clearing one of the vehicles, the truck suddenly jolted backwards hitting a tree. So then, with my foot on the brake, I put the truck in drive so that I could pull forward away from the tree. As I began to press on the gas pedal and the truck instantly thrust forward, hitting another tree, stopping the truck & knocking the tree over. It happened with such power that the wheels spun down into the mulch bed before I was able to brake, put the truck into park and remove the keys to turn it off. While the damage on the back bumper was minimal, the damage to the front of the truck was extensive & the insurance company declared the truck a total loss. There was one other time, while on the local highway at a stoplight, with my foot on the brake, that the truck began to thrust forward on its' own. After it first rocked forward, I pressed the brake all the way to the floor which prevented it from actually moving forward any more. Once the light turned green, the truck seemed to return to normal functioning. This incident occurred around the time I was due for a tune-up so I figured it was a fluke and would have been resolved with the tune up.
Driving along and suddenly the engine reved and the transmission was no engaged. I pulled off the highway and turned the engine off and started again with no problem. Since then, my transmission has quit while driving several times. I did discover if I turned the od odd it would work but has no overdrive. Fortinately, I was able to pull over and not have an accident. This is a dangerous issue and needs to be addressed by ford with a recall and repair.
I own a 2004 f-150 with 120,000 miles. When I am stopped and start to turn the rear end makes a horrible shaking noise. I have owned this truck for 40,000 miles and it has always had this broblem. If fords company slogan is built tough then this types of problems should be recalled. It seems majority of 2004 owners are having the same problem
80, 000 miles on the truck, and it now needs its rear differential replaced for the 6th time. On top of that , now the cam phasers are going bad. Can't drive it now again as it may leave me stranded in an intersection again. I drive 7 miles each way to work, and occasionally use the truck for vacations.
My truck gets up to about 50 MPH then acts like it goes into neutral , no power to the back wheels. I've noticed that more than a few 2004 f-150 owners have the same complaint. Has any investigation been done and if so what were the findings. I live on disability social security and can't afford to have a transmission repaired.I was on a paved road at the time.
Takata recall : truck is slipping in forward gears and the reverse will not move even if u you rev it up it's like it's in neutral. All this happened when I was leaving work to go home
Grinding in rear axle assembly, differential needs rebuild,57k...
Unknown. Major popping in rear end while turning. When truck is in park I can roll it back and forth a good 10 inches in both directions.
Vibration at 45 to 55. When cold strong jerk in rear end area and sometimes on turn to right. Also comes in at times when going to passing gear. It is a differential issue more than a drive shaft issue. All u joints are tight. No imbalance in drive shaft. Have gone to special teflon gear oil... This appears to be design and possible safety issue.
112,000 and sent the truck in for a humming noise . The whole rear end needed to be replaced. The truck has had only highway driving with no off roading. Differential oil replaced every year.
Took truck to get tune up but was told I couldn't get warranty to help pay for service badly needed and due to that I lost work and was almost homeless but ended up getting help from my mother for tires that took 5 days and was a big headake at wallmart but that's another thing .its a long story but I'm doing my best to have a decent running truck that I can rely on to keep jobs.I just want it fixed so I had to become a mechanic just to find out there is a recall on theses motercraft 515 spark plugs and would like help to get copinsation and have repairs that is needs attion asap .long story short I love my ford truck and learned a lot along the way please help.
Tl* the contact owns a 2004 ford f-150. After exiting the vehicle with the transmission in park, the vehicle suddenly began to drive in reverse. The contact was able to get back inside to stop the vehicle. Upon inspection, the contact discovered that the shift lever became disconnected. The cause of the failure was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 138,000.
Within a few weeks of purchasing my vehicle in february after pulling into a parking lot the check engine light came on. I also noticed it was making a ticking noise like a diesel engine but it's not a diesel. I went to get the codes and found it was a retarded variable valve timing issue code p0022. I looked online and went to multiple shops and mechanics to figure out the problem. After paying to replace the vct solenoids it was apparent that that was not the issue causing the timing problem. For weeks I noticed the truck shaking and at one point it actually stalled as I was pulling out of a parking lot into a busy road and it stalled as I was going into the road which caused the on coming traffic to slow and stop to avoid hitting me in the middle of the road. After spending weeks in the dealership service shop and a large sum of money they found they needed to replace the engine entirely. I have witnessed this issue happening to many many others online and in person who have the same year range with the 5.4l 3 valve triton engines. This is absolutely unacceptable for so many vehicle to have the same issue especially when it has under 100,000 miles. It is not only very poor quality for such a large price but also a safety hazard to the owner and others around these vehicles.
The rear differential acts up and prevents the truck from accelerating properly. Stutters all of the time and has a mild misfire and what sounds like knocking.
I noticed that the cruise control started shutting off without ever touching the brake pedal or off switch. Then sometimes it would work fine for a few minutes then just shut off. When it does that it will not come back on again till the next day. I then checked the console shifter, I was able to shift of park with out pressing the brake pedal and even engine in off position. I am worried that the truck may jump out of park and run off and hit something or someone.
Original owner of 2004 ford f150 fx4. From stop the rear end will vibrate as I accelerate. It's been doing it for quite a while. I believe it started around 40000 miles. I only have 54000 on it currently. So it has been like this for at least 3 or 4 years. It sounds like this is a pretty common issue. Does should definitely fix this known issue.
Truck rear end shakes violently upon acceleration at any speed or from a stand still. I had the rear end serviced and had the fluid flushed, but it only corrected the issue for a short amount of time. As time goes on, this issue only worsens. Ford has issued a service bulletin for a defective clutch pack(s) in the rear differential, but not a recall. This makes the vehicle feel unsafe and makes acceleration uneasy, especially when merging into moving traffic.
Tl* the contact owns a 2004 ford f-150. The contact stated that while driving at 45 MPH, the vehicle decelerated to 30 MPH without warning. The contact was able to drive the vehicle. The contact performed a diagnostic and found that the transmission needed to be replaced. The transmission was not replaced. The manufacturer was not made aware of the failure. The approximate failure mileage was 90,000.
Officially logging a well known problem with the 2004 f150 driveline. It has done this to the point of transmission replacement due to wear on the shaft. The driveshaft is not serviceable at all and was never lubed from the factory causing binding on the slip yokes which in turn causes swing bearing wear, u joint failure and to the point of transmission stub shaft wear ultimately causing failure. There seriously needs to be accountability for these due to the severity and liability. We owned the truck new and have driven with this problem until now. I hope to see a recall soon as tsbs are no help to the customer and most dealers do not even know that these parts are unserviceable. As a life long customer, thumbs down on ford to allow this to go on.
I have a problem it pops up saying transmission fault and I want to fix it so help me please!!
Heard an exhaust leak and thought is was a muffler. Mechanic looked at problem and alerted me to the fact the driver side exhaust manifold was rusted and warped. There is also some damaged bolts being rusted or broken off. Truck is a ford f150 heritage 2004, with 23,531 miles. Dealer will not repair due to out of time warranty.
While starting from a dead stop noticed a rumbling sound coming from the rear end. I had the rear differential fluid replaced, u-joints checked, and brakes inspected. (have had this done 3 times in the last 18 months at a cost of several hundred dollars)I mentioned this problem during a casual conversation with a friend who happened to be a retired ford mechanic. He told me that while he was with ford as a mechanic he replaced or rebuilt numerous rear slip differentials, and that it was a major problem especially with the 2004 f-150, and that I should investigate it further. I went on-line and found many many complaints about the 2004 f-150 regarding rear slip differential \with very expensive repair problems. Obviously ford has known about this problem for a very long time, and has done nothing about except to offer lame excuses and charge exorbitant prices for repairs. I am concerned about the rear end locking up at highway speed and causing a fatal accident. Why hasn't a recall been required?
Experiencing shudders and shakes when accelerating.
Malfunctioning differential- when starting from a stopped position, (especially from a turn) vibrations occur and posses a risk of a potential failure when pulling into oncoming traffic.
This is a recurrence, paid for it the 1st time. After driving a few miles and coming to a stop the rear differential chatters really bad until the vehicle has finished cornering.
My rear end differential - axle went out and it's making a noise and feels like my rear end is lose when I drive down the highway almost feels unsafe but it is too pricey to fix I feel I should be something ford should fix or recall.
Tl* the contact owns a 2004 ford f-150. The contact stated that the driver was exiting a parking area when a loud noised was heard from underneath the vehicle. The contact inspected the vehicle and found that the drive shaft was fractured in half and caused damage to the fuel tank and muffler. The vehicle was towed to the contact's home. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure and current mileage were 146,000.
Had a loud whinning noise I could hear when driving, but when I let off the gas it wouldn't be as loud and pretty much go away. It was not tire noise or hum. Just hit a 100,000 miles and the noise had gotten a lot louder. I read lots information online and found it to be the pinion bearing. Took it to local repair shop and they confirmed that the pinion bearing had gone bad. This is very surprising that so many 2004 and newer f150 owners are having this same problem and nothing is being done by ford. I think they are turning a blind eye because of the cost of parts and amount of time of labor. Besides the pinion bearing, also had to do other bearings and seal. Truck is not driven hard at all.
