Ford Super Duty (1999-2016) :: Loud Thunk / Shudder And No Gear
May 4, 2013
I just broke my 2000 F350 7.3L 4X4. I never had any shift problems in the 3+ years I've had this truck. 3 days ago, I stood on it to enter the freeway, it dropped into passing gear, then a loud THUNK, a shudder, and no gears whatsoever. I coasted to a stop, checked to make sure the transfer case hadn't jumped to neutral, ran the tranny through all gears, and nothing, truck wouldn't move.
I took the tranny pan off this morning and its clean, just a little fuzzy on the magnet but nothing more than normal for 3 years and 200k miles without service. At this point, I'm thinking its the torque converter let go and won't pump fluid. Tranny Shops only want to sell you the whole assembly, not fix the problem.

The Truck: 2011, 250, 4x4, Super Cab, 6' box, 6.2 with 6R140, currently 40K miles. It did have an 8' plow on it. An 80 year old gent plowed his personal 200' driveway with it for 2 winters before I bought it. You can tell the truck was taken care of, or I wouldn't have purchased it. I have all the service records. He had his local dealer do all of it. Plow and all the controls were removed prior to my purchase.
Scenario: Trucks cold (summer ambient). Driveway has a grade down to road. Doesn't matter if I am nosed or backed in. Start up, back/pull out of driveway on to flat road, and very slowly take off. The 1-2 shift produces a lose thunk sound and sensation, very faint not loud. Almost Like a lose motor mount. Only will do it once, only on the first start and 1-2 upshift. Ive tried to reproduce it after the first occurrence, no luck. If you gas it under the same circumstances it wont do it.
It doesn't necessarily feel like an internal trans problem. More of a "somethings just lose enough to shift or move" problem. Sounds like somethings hitting the frame, core support, cab floor on this slow 1-2 up-shift. Its upfront passenger side. I've spent several hours under it looking for lose items witness rub marks etc...to no avail
Again it only does it after it sits or upon the first start in the AM or when leaving work PM. Not when its warm.

When decelerating from 40-50+ mph, I sometimes hear a ticking sound, like a clock winding down. The ticking gets slower and slower and then when I'm around 10 mph, the ticking abruptly stops and I hear and feel a loud/strong clunk.
It doesn't happen every time I decelerate, but it does happen a few times every time I drive it. Once in a while it will happen when slowing down from slower speeds, but only after I've been in stop and go traffic for a while.
I read about the slip joint grease problem, so I tried that, but my problem is still there. It's a manual transmission, 4wd, 5.4L F-250 Super Duty standard cab, long bed.

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.

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.

I have a 14 F250 Superduty with 6k miles, it has started a shudder around 40-45. It only does it briefly if I let off the gas and then accelerate it goes away.

My truck seems to shudder between 40 and 60 mph when it's in OD. If I turn off OD it seems to go away with the increased rpm's. Although I can't be sure if it genuinely disappears or if I just don't notice since I'm at 2100 rpms instead of 1500. Trans fluid is clean. Is this a common problem in these trucks? Just filled up from flat E the same day air temps about 4 deg. Truck was fully warmed up. Does this sound ignition related, tranny or fuel related?

Driving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.

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 have a 2010 f-450 with 87K miles. 6.4 engine, auto trans, 4wd, and 4.11 rear. All seems fine in the earlier gears....in the later gears...at around 40mph...there's a very noticable shudder...enough to cause you to slow it down...since the shudder shakes the truck...then at about 35mph...it stops. repeat the speeds...shudder repeats.
Trans fluid is clear and all vehicle fluids and filters have been changed during the 4000 miles I have owned the truck....with the correct fluids, filters, and additives. There's also what sounds like a coasting whirling noise in the torque converter area while in neutral....which may or may not be related.
The last time all was normal...a bang .....as if I ran over a cinder block (which I did not) occurred...leading me to believe a bolt or part sheared. There is no metal in the magnetic drain plug of the tranny filter.
There are no codes indicated other than ODBC drive cycle incomplete. I do not see any obvious damage on any of the universal joints...

I just bought my 2015 F350 long bed Platinum a month ago, and the first trip with my 12,000 lb. 5th wheel had a vibration when starting out, but only from a stoplight with some acceleration or an incline, not at level slow startup.

My vehicle had a shudder which felt like driving over a rumble strip. It would usually occur after hitting a small bump at around 35 mph and hearing a clunk underneath. The shudder lasted just a few seconds. Checked the whole steering, suspension, chassis, drivetrain, u-joints, rear e-brake shoes etc. Finally found that the RF axle shaft could be moved up and down excessively in the steering knuckle. Removed axle shaft, R&R u-joint, vacuum hub seal and the torrington bearing in the hub. (used to call it a spindle bearing) ...
There was a little bit of wear into the stub shaft where the spindle bearing rides. That removed the play from the axle when it was all re-assembled. I was very happy until about a month later when it started doing it again, but not as bad as it was originally. I think maybe the stub end of the axle shaft needs to be replaced due to the wear in it. I don't want to just throw a somewhat expensive part at it without some info about "superduty shudder".

My 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)
Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.

Truck is 2011, F350, 4x4 CC Long box with a 6.2, 124,000 km on it. Was driving home last night towing my jet boat when I heard a sudden noise from the front end, kind of shudder, first reaction was a flat so headed to the curd. No flat, nothing running hot, no play in wheels, all looked good underneath the front end. Pulled out and drove away, got about 15 km and it happened again, looked all around nothing obvious so pulled out and drove home (25 km) no issue.
This morning wanted to investigate further. Drove truck down the block and heard a definite rotating type sound. Not a grinding more like a scrape sound. After a minute it went away. Went into a parking lot and drove in tight circles but no strange noise. Found that the auto locking hubs were not working but hub would lock in manual. No strange noises with hubs locked in either.
Jacked up truck rotate front wheels, no sound and no play or wiggle on either side. Pulled the hubs and the passenger side had water in it. Hub was not rusty but it didn't look as good as the other side. Not sure how water got there as I have never driven in water, although I am not original owner but have had it two years and put 25,000 km on it. Could the water have gone in deeper and caused a bearing to fail?

I have a 2006 F250 Lariat CC FX4. I bought the truck with 68,000 miles about 3 months ago. This is my first 4WD and I'm wondering if I need shocks.
I know how to check on a car but this suspension is too stiff to push down a corner so how do you test? Or do you just go by the age? At freeway speeds when I hit a bump I get a bit of a shudder that makes me wonder if the axle is hopping.
If I were to replace them are the Rancho shocks OK for a replacement? I will spend very little time off road and mostly use this truck for boat towing and hope to buy a travel trailer down the road.

My '11 F250 stock w/airbags has a mild shudder when I let off the gas approaching a stop light. If I air the bags up to about 20 lbs it appears to go away, or at least is undetectable. I don't notice this if travelling at a higher rate of speed on a highway but only when slowing down from a lower speed (<40 mph). What this could be?

2008 F250 Crew Cab 5.4, 79K miles, had new brake pads installed at 40K miles. Recently, I noticed front end shudder and some pedal pulsation while braking. It started kind of sudden. My first thought was a warped rotor.
When I took things apart, I found passenger side front rotor was cracked and the caliper pistons were rusted and falling apart, the old pads were only worn about half way. My thoughts on a bad rotor were confirmed, and then some.
I replaced the broken caliper, both front rotors, installed new pads on all four wheels, and bled the brakes. To my surprise, the brake shuddering did not go away. I'm stumped.

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?

I have a 99 f250 4x4 super duty. Just started getting a loud squealing noise off and on in the front end. Changed the ujoints and axle seals on both sides. They where all in bad shape. It still makes the noise off and on while in 2wd. If I lock the hubs in it doesn't. What it could be ?
