Ford Super Duty (1999-2016) :: Thump / Bump While Accelerating

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.

Ford Super Duty (1999-2016) :: F250 - Thump While Backing Up - Loss Of Reverse And Park

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.

Ford Super Duty (1999-2016) :: 2011 F250 - Rear End Shudder When Letting Off Gas While Stopping?

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?

Ford Super Duty (1999-2016) :: 2002 F250 4X4 - Front End Shaking And Brakes Began To Intermittently Hum When Stopping

Problem started with the front end shaking a little bit when braking like the rotors needed turning. Then the brakes began to intermittently hum when stopping. Then my ABS light came on. Put the truck up on the stands and disassembled the brakes on both sides. The ABS sensor was chewed up on the driver side. The less than year old hub felt sloppy so I changed it. Put everything back together.

New hub came with new ABS sensor. Went for a test drive ABS light is gone and I no longer shake or experience the hum when applying the brakes. However now when I go to stop right before I come to a complete stop the driver side (new hub/spindle side) I hear what sounds like the grade school class clown making a fart sound with his mouth, and the truck pulls to the driver side. Is the ABS system malfunctioning or is this a caliper issue? Calipers look like they are OEM.

Ford Super Duty (1999-2016) :: 2001 F250 - Rear End Slip / Bump When Initially Starting From A Dead Stop

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?

Ford Super Duty (1999-2016) :: AC Not Blowing / Small Thump Of Clutch Engaging On Compressor

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...

Ford Super Duty (1999-2016) :: Slight Thump From The Area Of Cruise Control Box Under The Hood

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?

Ford Super Duty (1999-2016) :: 2008 - Clunk When Starting Or Stopping

I have an 08 F-250 CC SB 4x4 Diesel truck that has since new clunked when starting out from a stop and/or coming to a stop. I have 16k on it now and am getting really tired of dealing with it... The clunk starting is when I let off the brake and just apply the throttle. It feels like something slips and then clunk.

The clunk when stopping is the same as starting, except when coming to a stop.This is unloaded or when loaded w/ cargo and/or trailers. I know I can go to the dealer, but I don't want to un-spartan my truck for this...

Ford Super Duty (1999-2016) :: Clunk At Rear End When Hit A Bump

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.

Ford Super Duty (1999-2016) :: 2003 - Hard Steering Whilst Stopping Or Slowing Down?

I have a 2003 f250 with the 7.3 power stroke in it. It is factory height on a set of 285/75 16 tires. It already has a reman steering pump and I replaced the steering gearbox today due to the truck having a little slop in the wheel. Since I bought the truck it is dang near impossible to park in a parking lot and almost impossible at a stop sign or being stopped to get it to turn whether I'm on the brakes or not it doesn't seem to make a difference. What else could be affecting the steering on the truck? All the steering components are good. I'm about by to the point of just selling the truck because it's that hard to steer. Especially trying to back a trailer is hard too.

Ford Super Duty (1999-2016) :: Grinding Noise In Left Front When Slowing And Stopping

TRUCK: 2003 F250 S/C Long bed 4x4 7.3 Diesel

PROBLEM: grinding noise in left front when slowing and stopping.

Starts as a howling noise, turns into a grinding as you brake and come to a stop. I feel it in the pedal and as it slows it feels like metal to metal brakes

WHAT HAVE WE DONE: Replaced both front hub assemblies (MOOG)... Replaced dust shields, rotors, calipers, pads as well as all new brake hardware.

At any speed when I brake hard it grinds and howls, I have taken out the 4x4 locking hub assembly and it does not change the situation. I am stumped!

Ford Super Duty (1999-2016) :: Bump Stops Rotted And Fell Off?

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?

Ford Super Duty (1999-2016) :: 2009 - Over Bump Wobble And Shake?

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.

Ford Super Duty (1999-2016) :: Grinding Noise And Clunk Felt In Brake Pedal Upon Stopping

I have a 2005 F-250 4x4 and recently i noticed a grinding noise while driving and then when I come to a stop I hear a clunk and the grinding stops. It sounded like it came from the driver side wheel so I changed the wheel bearing assembly. About 3 days later it started again. Now it sounds like it's coming from both sides. I am at a loss. The hubs are unlocked. It's hard to describe the sound but to me it sounds like 2 gears with a large chain rotating on them. I hope that made sense. The clunk can be felt in the brake pedal.
