Ford Super Duty (1999-2016) :: 2004 - Loud Rattle Under The Hood When Lift Off The Accelerator Pedal
Oct 29, 2014
I bought a 2004 F250 super duty 4x4 with the 6.0 a couple weeks ago and have a few questions. Hopefully all of these things are normal, but I thought I would ask you experienced drivers.
1) Occasionally while driving when I lift off the accelerator pedal I can hear a sort of loud rattle under the hood. I assume this is the turbo shutting down? Is that normal?
2) 4x4 and locking hubs... I have the 4x4 hi and low switch on the dash. Do I need to also manually lock the hubs to go into 4x4? After reading the manual it seems like I can just turn the dash switch and they should automatically lock, but I'm not sure. The hubs are not marked, but going by the pictures in the manual I think I know which is "lock" and which position is "auto" or off.
3) Front wheels hop at full turn. I expected wheel hop in 4x4 or with the hubs locked, but even in 2WD with the hubs in the auto position the tires still "hop" or knock a bit at sharp turns. Is this normal?

I got to replace mine because the hood won't stay up on it's own and is heavy to lift. I was wondering if these things fail often. Mine is an '08.

I have a 2004 Ford F250 Turbo Diesel, egr delete, headstuds, intake, dual stacks, etc and when i turn my wheel a loud whining noise comes from under the hood, I noticed it put tension in my brakes. When I accelerate it gets louder and when i let off the gas it goes away... i checked my fluid in my steering pump and it was low so i put some more in and the next day it was all sitting under neath the truck.... any quick fix or do i need to replace the whole pump?

Truck details:
2008 f350 6.4 290,000 klm
DPF and full EGR delete
K&N intake
IDP custom street tune
Loud squealing noise that happens when cold or at temp.
2000 to 2500 rpm's to 3000 rpm then it goes away
Happens only when accelerating over 50% anything under and the noise doesn't happen.
15 to 20 pounds of boost
Turbo sounds good
No codes
All plumbing looks sealed and tight
Fuel coolant res is full and clean
I'm thinking it could be the lift pump dying or having trouble supplying the fuel demand. Started after I did the cold air intake....

I have a 99 F250 7.3PSD; I upgraded the tranny cooler after an episode of overheating while backing up a hill.
The truck has done well, hauled a few tractors with it, but recently I have noticed something that seems scary. When going downhill, I often relax on the accelerator. Usually there is some passive engine braking as happens with any auto tranny. Recently, the truck just coasts - it is as if you feel the tranny shift into neutral and you just coast, except I didn't shift. While this is happening, the accelerator pedal will not rev the engine. You can put the pedal all the way down -> rpms at about 6-800. No response.
At the bottom of the hill (so far) the engine gets louder. the rpms drop, and the accelerator works again. Every time, so far. But, if IO am going down hill, and want to accelerate to execute a laneg change or something - I can't. AFAIK, everything A-OK after the new tranny cooler. levels, etc.

I was driving, Iput the brakes on then suddenly I heard a loud bang and brake pedal went all the way to the floor. I knew there was something wrong with the brakes, parked went and checked the passenger side rear brake caliper was ripped off which made a hole through my rim and also ripped off the brake lines. I need to get the part but I don't know what its called. See the pictures....

Recently on two occasions I pressed the accelerator clear to the floor with no response. After shifting into Park then back into Drive it drove normally for about a week. Now it has stalled out and was very stubborn to restart. Once running, the accelerator will sluggishly rev the engine while in Park, but in Drive, will not respond. TPS sensor or something else?

So last week I installed a 6" lift and once we got it done I could barley turn right at all. So I decided to put a drop pitman arm on yesterday with a buddy, thinking that was the issue. But I still have the problem, and I very badly need to fix it and don't know what it is. Turning left is completely fine however. It feels like I'm trying to steer an 18 wheeler right now.

Looking to upgrade my tires and would like to go a hair bigger but nothing radical. I have the 20's now, what's the biggest size I can go to with no lift.

I have a fabtech 4 link 6" lift on a 2008 6.4. The lift kit used to sit level but the front is sitting lower now. How can I fix this?

So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?

I finally got my lift installed the other day from PMF. My question is how do I get my pinion angle corrected on the front drive shaft? I know Trevor sells a Tcase clocking adapter may have to go that route IDK Unlike the rear there's only so much pitch you can put on the front axle until it causes issues with steering. I was thinking of going with an aftermarket front drive shaft designed to handle harsher angles.
I live in the mountains and after installing the lift and pulling a trailer on some of theses steeper gravel roads I can feel a harshness or something coming from under to front of the truck. I'm unable to post pics since I'm back on the road but I can visually see the front drive shaft angle is definitely not in line like it was.
I'm currently running PMF 2.5 alpha with a 1'' spacer and 3 link kit up front and 5'' progressive leafs and traction bars out back. I was able to fix my rear shaft angle using shims on my carrier bearing ( not really a big fan having 1 1/2'' of stacked shims BTW ) ....

I have a 02 f250 powerstroke and I wanna put a suspension lift kit on it I wanna go with a 6 inch lift but I'm afraid if I go any higher than a 4 inch I'll have to change to much. What I would have to change and if I would have to extend any of my brake lines also the truck is a cab and a half with an 8 foot bed so I do have a carrier baring on the drive shaft would I have to change anything with that?

2003 f250 6" lift on 35s. How to lift the suspension to change out spring bushings? Was thinking using two chain falls on tow hooks on the front, any easier, safe, cheaper way. I have a farm jack but need to weld a plate on bottom of it for more support...

Put in 2.5" leveling blocks under front coil springs. Now I hear a clunk nearly every time I turn to the right. Why this might be?

Just installed a 4" lift sunday, with a BDS drop pitman arm and then i retorqued it to 185 ft/lb. I now have this extremely low speed (<2mph) or stopped clunking whenever i turn the wheel. I just replaced the upper and lower tie rod that goes from the pitman arm, and its still doing the same thing. Steering box is shot?

When installing front lift shackles, do you place jack stands under the axle, or the frame? I can't really find an answer. I assumed the axle, but i saw a thread and from what i could see it looked like it was supported at the frame and the axle was hanging free in the air. Just want to be sure before i start unbolting the stock shackles tomorrow and kill myself.

I don't know whats up with my new truck, its a 04 f250 scsb, 4x4, 5.4l with 61k orig miles on it. Truck will stop on a dime, has NO pedal sinking, but it takes about 3/4 of the pedals travel to apply pressure to the pads and have the truck stop, sometimes if I push the pedal down then let up and push it again the pedal wont travel as far, I just flushed the system today, no air in the lines, is there a bleeder on the abs? truck has 4 wheel abs...

Intermittent accelerator problem: no response, just goes to idle. Runs perfectly with no other issues but zero response when the accelerator it pressed. There seems to be no pattern to the problem as this happens at any speed/position on the pedal. When the accelerator goes out the check engine light in the lower left corner comes on. All fuses are good.
Symptoms began a month or so ago feeling like an occasional 'hiccup' or hesitation. Symptoms occurred a few more times until a couple of weeks ago (Friday, 2/20/15) when it left my son stranded a few miles from home. He was able to limp it to a parking lot and we left it over night and went and towed it back to the house the next morning. The truck started and ran fine just no accelerator so we towed it idling so we would have power steering/brakes, etc. As we neared the house the engine light went out and the accelerator began working and he was able to drive the truck the remaining 1/2 mile home.
Most all of the research I did came back with the Throttle Position Sensor as the culprit. I was able to order one (the complete accelerator pedal assembly that is*) at a Napa store in a nearby town and picked it up on Tuesday (2/24). As soon as I installed it everything worked fine.
As an aside, I have read a lot about the mid-2001 switch from the units with the TPS (Throttle Position Sensor) and IVS (Idle Validation Switch) as separately connected units to the 'new' style where these parts are combined into one and there is a single 5-wire connector. Being a 2002 there was no question as to which one I had. Just be aware of the difference. Also, this part is simple to change. The connector has a clip that you pinch down on with your thumb and then pull off. I use my little electric impact with 1/4" extension and a 10mm socket. Zip, zip, zip an you're done. It takes me longer to get my tools out.
A few days later on Friday (2/27) it presented the sporadic accelerator symptom a couple of times again but was able to get the truck home. The next morning I unplugged, cleaned (CRC Contact Cleaner), and dabbed into the connector a small amount of dielectric grease to insure good connection. (I had read that in my research as well). That seemed to work beautifully and he said it ran fine all day and until the next afternoon (Sunday, 3/1) when it began acting up yet again.
I continued to research and could find nothing that would suggest anything other than the Throttle Position Sensor. I read that some other folks had gone through a few of the Napa/aftermarket units though so I began thinking that maybe I had just gotten a bad unit.
