Ford F-150 (2004-2008) :: Rear End Starts Locking Up When Put Truck In 4wd
Oct 18, 2015
When I put truck in 4wd rear end starts locking up. Take out of 4wd its fine. Just put 2 quarts of fluid. They didn't have the 75-140 so I put in 85-140 was that bad. Had rear rebuilt a year ago. Mechanic said he had to put a different gear assembly because ford didn't make the original any more. Ever since this was done rear just never seemed right. Now in 4wd if I go straight it's fine but as soon as I make a turn rear locks up almost coming to a grinding stop.

I just bought a 2007 fx 4 with 116000 miles it has the triton 5.4. I know I test drove it good etc well I am out of town with work right now and drive it on a 400 mile trip and noticed that when you are in overdrive and going up a small incline it acts like the truck is locking up, if i get on the gas a lil and make it shift it stops.
The truck shifts smooth and everything on this truck is tight no clunks or nothing. Ihope its not the transmission and sometimes after putting it in park and idling and turnings steering wheel it will start idling really rough . What could this be only does it speeds 50-57 like i said if i make it shift it stops....

Read a few references but nothing seems the same as what I have... 2001 Ford F150 Larite 5.4L 4 x 4
When slowing down, at speeds of 3 to 4 miles per hours truck starts to shutter. It is not an engine issue, nor a brake as it will occur with brakes on or not applied. Engine is running smooth, seems more mechanical that fuel or brake related. Shutter is not slight either.
Both CV axles, hubs, rotors and upper and lower A Frames have been replaced. Shutter was happening prior to the replacement, they were replaced as preventive maintenance. Shutter is profound enough to shake the mirrors. What it can be.

I'm posting this for my neighbor who has a F250 that's 8 years old. He has replaced many parts, engine from what I know but now when he starts the truck it starts fine but as soon as he starts the truck, the brakes lock up. He can't move it. He hasn't had the chance to move it because the brakes lock as soon as the truck starts. It starts fine and idles fine but can't move because the brakes are locked. Tomorrow the tow truck will haul it to the ford dealership so they can look at it and run the diagnosis computer on it.

I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?

I just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.

I have a new to me 2005 F150 with 86,000 miles. When I am driving through town at a low acceleration or a constant speed at between 40 - 50 mph the truck starts to sputter and kick a bit. When I give it some gas the problem goes away. This gets worse when I pull my bass boat, and starts at around 30 mph. When I hook it up to a reader I get a P0316 code. Only code I get.
Also when I am driving through my neighborhood between 20 - 30 mph I get a noise that sounds like there is a plastic bag stuck under the truck. I have checked under the truck to see if the firewall is loose anywhere, but could not find anything. Other than those two issues the truck runs great. What these problems could be?

This is concerning my little brothers truck. It is a 2008 4.2 liter with around 55,000 miles on it.
He drove it to work today, and called me this afternoon saying that the truck starts then dies a few seconds later, and the battery light illuminates. He and a coworker checked the battery and connections....cleaned off corrosion on terminals, battery reads 12.xx volts without a load on it, it is the original though.
As of right now he is changing the fuel filter which hasn't been done yet. I also know of issues with the fuel pump driver module. I remember checking the one on my 2005 back when I owned it. As I recall it causes a no start condition, but would it cause a start then stop condition like this? He will check this when he is done with the filter.
Anything else that we can check in a parking lot to try and at least get it home?

I have a 2008 xlt with a 3.0. In the little over 2 years I've had it, most notably in the past year, I have replaced the front driver side ABS sensor 8 times. This is getting extremely cost, and outrageous. Every month or so, the ABS light comes on and the ABS starts locking up when I am driving it. Every time it does it, I have to take it back to the shop for diagnostics, at a rate of nearly 300 a pop. As you can see, the bill for this one damn sensor has become outrageous.
Every time, the same fault code comes up. Drivers front ABS sensor. Putting on a new sensor fixes it, every time, but only temporarily. I have had the tone ring replaced just to make sure that wasn't it, and every single time it's always been the sensor itself.
I have tried various brands, including a couple of OEM a pop to make sure it wasn't just lower quality parts, and I have the exact same result every time. I have noticed it seems to do it most notably during extremely wet conditions, or heavy snow, although a couple of the times it started acting up in the heat of summer. I have even attempted cleaning the abs sensor to make sure it wasn't just dirty, to no avail.
As I mentioned, only replacing the sensor makes the issue go away, and when I am driving the abs system engages at random times if I leave the light on for too long without fixing the abs light.

I have an 04 F150 5.4. Anyway drove truck about 200 miles this weekend. When I got back home, unloaded truck, noticed a fluid leak on the ground in the rear of truck. Upon further inspection, appears to be leaking from where the driveshaft meets the rear axle...looks like there's a gasket or yoke in the rear of the U joint? a little fluid dripped down and ran down to the lower portion of the "pumpkin" and made a quarter size oil patch in front of my house.
I would have definitely noticed such a stain before, since I park in the same spot at home and work every day. I drove to work today (14 miles) and looked under the truck for 15 minutes after I parked, don't see any drip, but do see remnants of a leak all over the front part of the rear axle. No way has any fluid leaked on the ground before, I 100% would have noticed a stain.
Thoughts on a fix for this? I had the clutch packs redone about 3 years ago under warranty, truck has 88k miles. No shudder when I drive from the rear axle, I'm assuming there is fluid in the rear gears, as a substantial leak I for sure would have seen on the ground. leak is 100% NOT coming from the seal on the rear axle, but in front of it where the shaft meets the axle. Possible that driving on the highway at 75MPH for 2 hours straight caused this leak, as my drive to work is mostly stop and go, both ways.

Ok I have a 2004 F150 Fx4 ext. cab. I had the truck for sale and due to something coming up I was unable to sell it. Kinda wish I did now. But anyways the truck was running great up until last week. I was drove it to work which I normally dont do. On my way home the rear end was making a weird noise. Kinda like a brake sticking. I tapped the brakes a few times and it seemed to work. Then a mile down the road it was doing it again without me trying to come to a stop and the back end was shaking. I pulled over and crawled under the truck to see if a u-joint was going bad. Everything seemed good. It never happened again until today.
This morning I hoped in the truck and went to my parents house. Its about a 5 mile drive and truck was acting fine. Came home and it was still fine. A few hours later I figured I would go up to the fire department I am on and find something to do up there. I got in the truck and didnt make it 5 feet from where I was parked and there was this bad noise followed by my whole truck shaking. It felt like the truck was going to fall in pieces in my driveway. I stopped looked around and didn't notice anything wrong. I figured I would just try to drive a little bit further and it was even worse. So I put it in reverse and it was normal. I put it in Drive again and thought my teeth were about to fall out of my mouth.
What could cause this? I know my transmission was leaking some oil from where the gear shifter comes out. I would check the trans fluid and add some if needed. I drove it up to the fire hall Monday night and did notice a slight burning smell but that was the only time I smelled it. Could it be the transmission?

my front brakes have been locking up here recently. I think it my be due to a blockage in the resovior. I had taken it apart upon the first spell of it locking up, had my buddy press the brake pedal a few times with the lines from the res disconnected and it seemed to be be a little clogged at first and then freed up once it was stepped on hard a few times. So i reassembled the system and bled the brakes out and it seemed to be fine for about 70 miles or so. Then out of no where it started locking up once again.

In removing the COPs on my 2004 F150 Lariat 5.4L for a spark plug change, I noticed that the locking tab on one of the electrical connectors that plugs into the COP is broken. The previous owner had a zip tie on it to keep it on. Can I purchase a new connector and splice it on so that I don't have to use a zip tie? If so, what is the part number?

I have a 2004 Ranger 4x4, 4.0, auto and have trouble with the back brakes howling, locking up and generally driving me nuts. I've replaced the drums, shoes, cylinders, emergency brake cables and all the hardware. We've bled all 4 numerous times, blown out the lines, looked for leaks and done all we can think of. What am I missing?

this is my brothers truck 05 f-150 4x4, i put brakes front and back and flushed the system about six months ago now. the other day when he was coming home from college the front passenger tire locked up. he drove it home and i went over took it apart nothing was sticking put it back together and it was fine. now today he call it stuck again so i just pulled it apart, pads are now purple from the heat, pins are free, caliper moves i put a small piece of wood in it and had him press the brakes the caliper moved out and i pused it back in, reinstalled everything and its not stuck no more. what do you think is causing this? my uncle says it could be the abs box acting up, when he bought the truck my dad made him buy the extended warrenty but he wont pay the 100 dollar deductible because this past winter we all went out in the two foot of snow and he got stuck so i pulled him out and our dad says thats what f$ucked his brakes up so now his is pissed. so how can i fix this for him? oh it only has 42k on it

I have a 04 F250 6.0 and change transmission and transfer case. Now all of a sudden the rear passenger tire is locking up but the rear driver side still moves. I've dropped the carrier and the ring and pinion looks great and so does the spider gears ... Need on whole new rear....

Ok, So, Im 40 miles from home stuck in ice and snow in a hotel.. (my wife works close by- thought it would be safer than driving in the 10 inches of snow we got 3 days in a row) so, I go to pick her up tonight and I engage 4hi.. I hear the click and the light comes on.. but no clunk of the hubs locking.. I drop it in 4 lo.. it shifts in low.. but the hubs are not locking..
I hear a ticking sound as I drive and when I put it in 2wd it goes away. I turn off the truck, turn the wheel hard both ways .. get out and I can physically turn the drive shaft and I hear the ticking in the hubs. If I read correctly when the truck is off these should be locked?
is it possible the vacuum is not releasing? I also get the groaning when I start up of the air diverter.. that im told is operated by vacuum.. so I am guessing I have a vacuum problem??

My driver door on my 06 F150 crew cab stopped locking/unlocking recently. I purchased a new actuator and installed and it worked great. About a week later it stopped working again. But then in order to unlock the door from outside you had to turn key and pull on handle while the key was still turned. I was about to break open door again when it made a strange electronic type sound when I was leaving for work (when auto lock activated). After that it started working again - for 3-4 days. Now it stopped working again. I can open door fine from inside but lock won't stay unlocked. As soon as I release handle it locks again.
