Ford Super Duty (1999-2016) :: 2004 F350 - Loud Clunk Noise In Forward Or Reverse Hi Or Lo When Accelerate
Jan 24, 2016
Ive 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.

It seems its the 4R100 tranny non pto of course and 2wd version. I drove down the rd. after bleeding the brakes, new caliper front right, came home let it idle for about 10 min, shut her down. Went to move it about an hour later, it went into reverse no problem, then when put it in Drive it revved like it was in neutral. There was no banging, no clunking, nothing to make it seem like something catastrophic happened.
I then did a line pressure test and Reverse was fine 200 psi for sure, in drive mode however it was low like around 50 but had to rev real high to get it to 150 like 3/4 pedal and it would want to seem to go forward at a crawl but nothing more. Next I did the obvious and cheked the fluid, it was about 1/4 quart low so added a bit. The fluid did not stink and was beautiful red like new.
I then tried again... no dice same scenario. Then took off the pan, no metal chunks and virtually no dust on the magnet??? Ok so I figure maybe something with the shift valves? Took them all off and the accumulators as well, all check ***** were in place and all valves moved freely.
Now onto the the solenoid pack, checked all per manual for ohms and all were perfect reads at about 27 Ohms, except the EPC solenoid that is the big one on the pack, it should read about 3-5 ohms but this guy is about 12.5 ohms.
I spoke to a tranny shop in town and they said it would not be the EPC and that I could "unplug" the solenoid pack and It would still move forward without it but not to drive like this as line pressure would skyrocket?
Why this thing would have 200 lbs pressure for reverse and so little for forward I mean? that should mean that the pump is working great, if there was a broken something metal I figured I would hear something rubbing or banging or see some shavings? Can this be a "worn out" valve? or gasket issue?

So the other day i opened the door and heard a super loud clunk noise come from the door and when I turned the car on and pulled hte window down it wouldn't go down all the way, only about 75% of the way so I assumed like BMW cars the window motor died but oddly it continued to go up and down just now 100% down.
Then 3 days later when I came to drive the car again the window went down to the 75% mark and now its jammed there with no movement even if I tried to lift the window up myself. Usually a broken motor allows this to happen but since it isn't budging I am wondering if its an electrical issue with the power window button more than the motor?
I say this because when i try to lower the passenger window from the driver side it works than out of no where on the 3rd time it wont move at all than 5 minutes later it will move or if it doesn't move I just go and pull the window down from the passenger side then I come to the driver side and try it and it works again than it'll stop again. So maybe its the power window control buttons on the drivers side that's failing?

It's an 04 F350 6.8L This past winter when it was cold I would start it up and it would rock forward and bounce back as is you shifted in to park while rolling. Now that it's warmed up it won't jerk forward but the whole body shakes only at start up. As much as I like the idea of of the raw torque being so powerful the truck twists with power I don't think that's the case.

I just bought a 2004 f350 4x4. There is a horrendous clunk coming from under the cab as soon as I steer and at certain rpm while driving straight. I have researched this topic for hours and everyone says sway bar links. Well here's what I have done so far and the truck still has the same terrible clunk. New sway bar links, new sway bar bushings on axle, new front drivers hub, new front passenger hub needle bearing, both front dust seals on axle, greased all ujoints and balljoints, tightened up some bolts for the dual steering stabilizer, and shook the heck out of all other ujoints and the cab mounts and they all seem good...

My issue, just purchased f250, 2004, v 10, manual transmission, state vehicle with 32,000 miles but was a plow vehicle for localRMV lot, that said, great shape and runs strong but I get a clunk and shutter when I am in reverse and only when I push down clutch before stopping. Doesn't do it starting forward or reverse, only reverse and when I push clutch in before stopping. Did have a friend drive and looks like the transfer case is moving, as if mounts or bolts are loose. Does this make sense and could bad slip joints be putting excess torque on ?!?!?

I took my truck to an alignment shop to have him look over my truck to find a steering wheel jerk and a loud clunk noise. He believes it's in the transfer case driveline. Said to remove the driveline then drive it around and see if it goes away, if it does then that's the problem. So to the question, how to properly take this out? Do I need to make marks with a paint pen anywhere to line things back up or does it matter?

New truck 11000kms ago thats done medium amount of work but nothing heavy or sustained for long periods of time. I get the feeling of clutches slipping especially when truck is cold but also when normal temps. Doesnt make any weird noises or anything. I can really notice the difference in torque if in manual mode being much better, but still not perfect if i stomp on the gas pedal and go through the gears in manual mode will still slip. Also is really harsh shift if i come to a halt in 3rd manual mode with the brake pedal depressed push minus button the truck makes very loud clunk noise into gear 2 then 1. Took it to ford they couldnt find anything ? Thinking of trying another dealer.

One of our trucks, 2004 F350 Powerstroke, my company truck, recently the last snow even we had, my tow haul mode would pop on and off almost evertime I shifted from drive to reverse while plowing. I didn't want it on, it just kept poping on and off. Thought maybe the button was stuck, but it moved like normal. My other thought was there is a loose connection in the shifter or column causing it to go on and off.

Have 2001 F-250 7.3 PSD, automatic, ESOF (had to replace the original hubs with Warns)have kept up the maintenance,oil, grease, ATF fluid & filter, truck has been virtually trouble free. About 2 weeks ago I decided to go across an area of the lawn, as I was going (in 2 wheel drive)I felt the tires spin a little so I stopped got out and locked the hubs, got back in truck turned t-case to 4 high. had to rock the truck out of a damp area but nothing really.
So I got back to where I came in at (in reverse about 100') stopped put it back in 2 wheel drive, tried to go forward, very difficult, sluggish, got back in driveway had to back the truck in, will not go forward at all now. Checked all fuses, rapped the the t-case motor, no codes. So I thought I'd move the ruck, have a winch that will pull it out by the barn, I could not even move the truck forward by pulling it with a winch. As I said have never had any problems with truck. Transmission fluid is good, clean no burnt smell.

I have a problem. 2002 F-350 4R100 tranny. Put a reman transmission in about 30000kms ago. pulled excellent with no problems. shut it off for night. In the morning it had absolutly no forward and a little bit of slipping reverse for a few minutes now it is totally dead. No movement either way. The OD on off flashed a few times but not anymore. Put a Genisys scanner on and no codes at all. What could be the issue?

My 2001 F250 5.4 has started to make a screeching sound. It only happens when it is in gear (auto) moving forwards or in reverse, and increases in pitch relative to engine speed rather than road speed, and is much more noticeable under mild to moderate acceleration. Maybe I actually mean transmission input speed?
When simply maintaining road speed, it is almost silent. Anyway, if I drop it into neutral while driving, the sound stops, and starts again when I put it back into gear.
From the drivers seat and with the windows closed, it sounds as though it is coming from the engine bay at steering column height, although this is really tough to gauge while actually looking where I am going. With windows open, it comes from both sides of the vehicle.
1st thought is tranny......
2nd thought is a water pump bearing, although there are no apparent cooling problems or leaks.
3rd thought is the alternator bearing, although there are no charging problems.
I say alternator because I recently changed the serpentine belt and noticed that the alternator made a very faint screech-like sound when spun without the belt on it. The main screech was there before I changed the belt. Maybe it gets really loud under load?
So I'm kinda scratching my bean and wondering what expensive piece of mechanics I'm going to shell out for next. If it's #2 or #3, I can do those myself, but if it's #1.... it likely means more money than I have to spare.
I did wonder about removing the serpentine belt and driving a very short distance (end of the driveway and back) to see if I can remove the pulleys, tensioner or other belt driven parts from the equation. Maybe this is not such a smart idea. I'm somewhat at a loss right now.

Was pulling passat home 50 miles round trip this saturday and downshifted into 3rd. As the gear engaged it let out a loud clunk locking into 3rd gear. was able to find neutral after a day but slammed into gear just idling. Can find neutral on pattern but not actually get there....also drags right rear tire upon disengaging clutch.

I have a 2003 F350 6.0 King Ranch. My first diesel truck. Bought it in March 2016. One owner with 102000 miles on it. Has a Bullet Proof oil cooler and 4 inch exhaust. Truck ran great until a week ago. Now, under any hard acceleration it blows out blue/gray smoke and does not seem to have as much power. Coolant level is constant and I cannot find any traces of water and oil mixing.

2011 F-350 XL, I can hear a squeal coming from the front brakes when rolling forward slowly, believe the pads are dragging on the rotors. If I touch the brake pedal the squeal stops as it does when I turn the wheel. Took the calipers off and greased the slide pins and put it all back together, still got the squeal. What don't I know???

I just picked up a 2003 F350 4X4 5.4L it has 130k on it. It drives ok, it doesn't seem to be able to accelerate very quickly and one thing I noticed is when i go into reverse it seems to stutter or feels like it scoots a little bit.

I have a 2005 king ranch and have a clunk coming from the back over bumps/heaves in the road. It doesn't happen all the time but often enough. I just replaced the shocks, that worked a little but didn't solve the problem. Now thinking rear sway bar end links? Anything I can check/inspect?

I drive a 2006 Ford F350 4x4 Crew Cab. I think the radius arm bushings on my truck are bad. I get a clunk going over bumps on the left side in the front end.
I'm assuming it is the bushing in the rear of the radius arm, but I haven't taken it apart yet because I want to have the parts in hand. I ordered a bushing, part number 5C3Z3B203AA. But it looks too small when I hold it up to it. What is the part numbers for the radius arm bushings?
Or am I looking at the wrong thing for the clunking in the front end? I just did the ball joints with Moog both sides top and bottom. The shock bushings look alright. I have replaced the front sway bar bushings thinking that was it. What else could it be?

I continuously read that people with 6.2 F250s averaging 13 mpg or so in a combination city/highway driving. This 2014 4x4 barely has enough power to move itself (honestly, I'd rather have my Ram 1500 back) and barely gets 10mpg. Basically have to give it about half-pedal to even get up to freeway speed and floor it if i want to pass anything. Is it just that much of a POS or does this not sound right? Other than a massive "clunk" sound when shifting from reverse to drive or vice versa, no indication of any problems.

I have read the older posts here on the super duty ford 4x4 system. At 60,000 miles I noticed what sounds like a gear or bearing noise, or even a whining noise like you would hear from mud grip tires, coming from the front end area, while driving back from Kentucky to Georgia. I have quiet running street tires on this pickup.
I have a 2004 F350 crew cab XL, automatic, 4x4, limited slip axles, 430 gearing and a V10. This truck has always been extremely quiet on the highway. This noise I described above has increased and the truck now has 70,000 miles. I have the factory 4x4 dash switch in my truck cab for the 4x4 engagement. I always thought the dash switch engaged and disengaged the transfer case, and locked or unlocked the automatic hubs.
The service guy at the dealer now tells me that the dash switch only locks and unlocks the front hubs, and the front drive shaft and front differential are engaged full time. So, after checking my tires for defects, and for any play or bearing noise in my wheel bearings, I am looking at pulling the drive shaft out keep the front differential from turning, to determine if I have a bad bearing in the front axle assembly.
Now I read some of the posts here, and they say that with the dash switch in "2 wheel drive", the transfer case should be disengaged and the front drive shaft and front axle should not be turning at all. What is turning up front with the 4x4 disengaged on the dash switch ? I'm afraid to drive my truck out of town now and I need to isolate this issue and get it repaired. This has been a great truck and it's very reliable.

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?
