Ford Super Duty (1999-2016) :: Thump / Bump While Accelerating
Aug 21, 2016
So lately I have noticed that my 99 F-250 has a bit of a "bump" while accelerating. Think of it as accelerating with a trailer and something is loose on the hitch, making a sort of bump or thump. I talked to the guy at the parts store and he said to put it in neutral and wiggle the driveshaft up and down, side to side.
When I did that it moved up and down, but not side to side, but I'm not sure if that's because it's just positioned that way or what. The wobble was coming from the slip yoke back by the rear diff. Is this something I should be concerned about? Also, I have an ext. cab and short box, 1 piece driveshaft.
Here's a video (a very crappy video at that), not sure if it gets enough info through or not but hopefully you kinda get how much play is in there.

My F-250 super duty has a bump thump when I stop if I release the the brake it goes thump bump? Does not do this if I put it neutral. Seems to do this in Acceleration from a stop, shifting goes bump sometimes, When hitting rough roads does not seem there bump thump suspension issues?? Already greased the drive spline joint the same, checked if there is anything loose nope, checked spare tire secure , 75,000 miles stock shocks?? something in the transfer case?? The rear end just had the seals replaced??? Tranny is secure??

I have a 2008 f-350 diesel, with 33k miles, I am getting a light thump or thud from the passenger side in the engine compartment, It does it when the truck is NOT moving as well as when it is moving. It use to do it only periodically but now it is doing it about every 1-2 minutes and it happened 3 times while we were sitting at a stop light.

Got in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...

2002 F250 SD 5.4 V8 here....cruise control doesn't work!!
-I've checked fuses 27 and 34. Good.
-I've done the self test. All lights flash with no codes given.
-I've replaced the pressure switch at the end of the brake manifold. All good.
-Horn works.
-No ABS lights or check engine lights on.
When I press the ON then SET...the guage illuminates on the dash and there's a slight 'thump' from what seems to be the area of the cruise control box under the hood (I'm driving so I'm assuming it's it).
Am I missing something here?? Can it be anything other than the box itself?

I was driving my 1999 F250 5.4 Triton last week, after noticing a thump while backing my small boat down the ramp (sounded like u joint) I went and parked. When I got back in the truck it starts fine but when I shift into reverse, it's staying in drive, anywhere I put my shift lever..... It's in drive! I even noticed that even all the way up into park it feels like it's in drive, but with something holding it back. If I give it gas while in park it will go forward! I have tightened the two torx screws under dash, pulled cable off and tried shifting by hand (clicks like switching gears, but still in drive) pulled pan, everything looked good there, fluid is nice and red, smells good, no metal in pan? It's the 4r100od tranny.

When I am driving and hit a bump in the road, especially when the rear tires contact it square. I hear a clunk at the rear end. Sounds like suspension, loose tailgate...
My truck is a 2016 F250 Crew Cab Short Bed. It has a factory installed fifth wheel hitch. I have looked at the obvious, spare tire, loose bolts... I removed the tailgate and it still makes the sound. I removed the insert in the receiver, still makes the sound. No goose neck ball in fifth wheel hitch. Checked bed bolts. Cant find it. Drives me crazy.
I also have a 2008, exact same truck, 200,000 miles, no clunking. I have driven in my friends 2014 F350 Crew Cab Long Bed, it clunks. Dealer pulled a new truck off the lot today, took a drive, it clunks. Dealer can't find it and confirms there is a clunk.

My Bump Stops have completely dry rotted and fell off the truck. I have an 08 with a 2 inch leveling kit, I already did all the body bushings, as they disintegrated as well. Should I bother replacing them? I highly doubt that I would ever bottom out that bad that I would need them?
If I should replace them, then where did u guy's get them and should I go with the Neoprene like I did with the body bushings?

I have an 09 F350 (116,000 miles) that I have only owned for about 3 months. I got it pretty cheap but it did have a front end issue. Drives fine most of the time but hit a bump just wrong at highway speed and it goes into a shake and wobble that feels like you just blew a front tire. Took it into my shop, not the dealer and was told I pretty much need a front end rebuild. Kinda what I figured I would hear.

I purchased the truck from a used car lot about 3 months ago and after driving for a few thousand miles I am feeling a slight wobble after hitting a bump in the road. Here is my truck set up:
- 2011 Ford Lariat F250 4X4 FX4 6.7 ltr
- 67400 miles
- Tires stock and great tread
- Rancho steering stabilizer kit
- Rancho Shocks
- Rear air bags
It does appear one of the rancho stabilizer dampers is leaking slightly. Why would the previous owner install a rancho stabilizer kit? Is it because of the rear air bags?

Got the death wobble, had everything replaced. Wobble was worse, upgraded track bar. Then no wobble but bad bump steer. Put on new OEM track bar.
Ok but still if I hit a hole on the interstate I get death wobble and little mini wobbles on any bump. What is the permanent fix for this other than selling the truck?
2011 6.7L FWD Lariat, upgraded exhaust and Def removed.

2000 F350. 4x4, V10. 153,xxx miles. Here's the story. Whenever I hit a little bump in the road, I get a vibration directly under my feet and in the gas pedal, NOT in the steering. It will go away pretty quick or when I hit another bump. It only happens when the front driveshaft is not spinning. Hubs locked in in 2WD, it doesn't vibrate. Hubs unlocked and in 4x4 High it doesn't vibrate.

I bought this truck a little over a year ago and have put almost 30,000 miles on it. When I bought it, it had a clunk from the front end, but only when I went over a significant bump. It was most pronounced when I, for example, hit a speed bump at an angle and the body rocked back and forth. It's steadily been getting worse and now it's fairly concerning. It happens on pretty much every bump now. Additionally, I've developed a fairly significant shimmy under braking and a vibration over 65mph. I got into a fairly scary shimmy when trying to slow down as I was going down a mountain a few weeks ago.
The other day I started getting a grinding noise from the front right. It goes away when the brakes are pressed. I don't know if the grinding noise and vibration/shimmy are related to the clunking or if they are the result of a separate issue. I have plenty of brake pad and rotor on all corners and there is no perceptible play in any of the front end components (wheel bearings, ball joints, tie rods, shock mounts, etc.). I suspected the leaf spring bushings, but I supported the truck by the frame and still got no noticeable play when jerking things around by hand.

Problem: 55-60+ mph hit a bump front end shakes violently. Slow down to 40 mph it stops. DOES NOT happen every time, and may only happen once a week, but when it does my whole front end feels like it will come loose.
Solutions to date that have not worked:
1. Rotate and balance tires. (tire shop)
2. New shocks. (me)
3. New steering stabilizer. (me)
4. Changed ball joint and bushing in track bar. (Dealership)
5. Check ball bearings and seem to be ok. (me)
6. Check tie rod ends and are ok. (Dealership)
The only other options people have given me:
1. Dual Steering Stabilizer. (Have had truck since Jan and hasn't done it in about 19,000 miles. Why would it need it now? Truck has 109,000 miles on it.)
2. New tires. (If it were the tires wouldn't it do it all the time? )

I have a E99 F350 7.3L 4x4 I know some or most of you have already probably replaced this part and or pulled a front axle shaft out. So here is my question...In the pictures provided you can see what I think everyone is calling a "Dust Seal" and as you can see it is bad and making a very terrible noise when i hit a bump...I was wondering what parts I would need to replace this seal? I tried looking it up and just get lost in all of the other things....I have found write-ups for the axle being removed while changing ball joints but none by it self to just replace this seal.

I'm completely aware a lifted truck will not ride factory and most likely ride harder. But this is ridiculous.
So I bought a 8" super lift for my F250 7.3 2000, although the price is very cheap at that shipped to my door debating if I have messed up either with the brand or somewhere because I feel like I went from a casual ride in my lovely 7.3 to feeling like a horse carriage of a few century's ago.
Lift is setup with lift leaf springs in the front, one add a leaf in the rear with a block, and 4 new shocks and all the other hardware included to do the lift.
I'm wondering if it's possible the springs are installed wrong, or the shocks are just that bad or if there a weird issue I've over looked.
Tire pressure is set to 35-40 psi all around on toyo open country mts, (which I was running before the lift so that hasn't changed) but I mean this is so stiff that when I hit a bump my steering wheel jerks and I feel like my suspension has absolutely no flex in it. Debating on returning to stock or not at this point...

My front driver side wheel is making a clunk noise when I hit a bump. I replaced the wheel bearing hub assembly and discovered both axle seals were bad.

I am a recent new owner of an 06 f350 Powerstroke. Steering Box developed a leak so I decided to replace the box and go ahead and do the pump and hoses while at it. Pump would make some noise so i figured I'd just do it all and be done with it or so I thought. The job was a pain, much harder than the pump and boxes i've done on the older 7.3 powerstroke.
Anyways, used all OEM components (pump was a rebuilt rotorcraft, can't buy new anymore) and everything seemed great for about a day. I tried to bleed the air out per standard practice of turning the wheels with the truck off the ground. At startup and during the first day it had almost no noise at all and the steering felt much easier than the old pump.
Then the pump started to develop the standard annoying ford power steering whine that I hear all the time. Drove it over the weekend on a 160 mile trip and the noise just kept getting worse. As of tonight I can't turn the wheel if the truck is stopped even with my foot off the brakes.
I used synthetic ATF for fluid and there is absolutely no foam or aeration in the reservoir. Good news is I don't have any leaks but the bad is I now don't have power steering. It does make a much louder whine or squeak when I hit a large bump turning, I guess that's just the sound of the pump being stressed more. I am guessing the pump just crapped out but before I do it all over again.

I've got a 2008 f-250 extra cab. A small bump will cause the rear driver side door to pop open. What I have to do to fix it, I don't want the grandkids falling out.

I am experiencing what feels like a "bump in the rear" when initially starting from a dead stop. It feels like a car behind me tapped the bumper or that the truck "hunkers down" first, then moves. Tranny seems fine also. Once moving, there is no problem whatsoever. There atre no noises, leaks, or other symptoms. Also, when coming to a stop, it feels the same way just before the truck completely stops. If I drift forward a little, then apply the accelerator, it does not "slip" or hunker down.
Took it to the dealer and they claim that they can't find anything wrong and may just be the suspension releasing? The truck does this whether loaded or not?
