Ford Super Duty (1999-2016) :: 2008 - Clunk When Starting Or Stopping
May 15, 2009
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...

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.

My rear wheel bearing are a little loose. This afternoon while diagnosing a squeak in the back I found this. While pushing the truck side to side there is a clunk and when you lay your hand on the tire you can feel it, bearings are loose. Nothing during the operation of the truck to give this away, truck runs and drives as it should but I need to check it our before something does go wrong. What I'm looking for is a torque / preload that the rear wheel bearings need to be set at.

I tow 10-15K; 6-10x per month with this truck. I can feel the braking ability starting to drop off so I want to get them done pretty quick. I am more or less happy with OEM performance but if there is a better value, and with my SO starting to haul the horse trailer around.. I wouldn't mind upgrading.
What is worth the money? I'm fresh out of school trying to figure out what the best value is.
Calipers?
Rotors?
Pads?
Brake Lines?
What would provide me with a noticeable improvement without breaking the bank?
Last question, could worn rotors cause vibration/shaking in the steering (primarily when turning ramps) at 50-60mph? Tires are brand new, problem showed up before they were replaced.

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 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.

New issue I've discovered , when stopping , the RPM's drop down to 500, truck acts like it wants to stall , then goes up to 750 RPM's . Then it's fine . Doesn't hesitate when accelerating . Idles slightly rough after start up , about 30 seconds . I've checked the air filter , cleaned the IAC and MAF. Fuel filter is only a year old . What I should check next ?

Recently purchased 2006 F-550. Noticed the brakes seemed a bit squishy and weren't stopping the truck as well as I thought they might. Looked under the car and saw this at the right rear tire. Give it to me straight, doc.

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!

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?

I need to solve tranny problem, it started out a while back, would not shift back into drive after stopping at stop sign (after driving fine for about 20 miles) thought maybe dirty filter so did fluid and filter change seemed to work for a while then started again noticed it was mostly after using cruise control, but u joints were very bad, so replaced 2 of the 3 and worked fine for about a thousand highway miles, then got really bad. Now when I check the tranny fluid cold and /or hot it is way up on the dipstick. Took to ford dealer in ladoga, lied and said no speed sensor codes, but list on the paper he gave me had all kinds of abs and a p500 code.

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?

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.

Whenever I take off from a stop or slow to a stop, there's a clunk in the drivetrain. It feels like a bit of play before the drivetrain engages and when it releases...torque converter maybe? Taking to the tranny shop soon...

So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?

2009 F350 4x4 DRW. Just replaced rod ends, drag link, sway bar bushings and end links, ball joints, and shocks. I have a clunk when the axle travels downward on bumps. The only thing I see is that the tie rod assembly will rotate easily by hand and I can make it clunk when I rotate it. It does not rotate in the ends, the ends rotate with it. Thinking this may be flopping around over a bump. Does tie rod rotate easily?

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.

I just got my truck back from the dealership where they said they tightened the nut on my pitman arm and now when turning either left or right when I approach full lock there is a massive pop or clunk that comes from the steering box. I have crawled under the truck and watched and felt everything as the wheels turn and the draglink, tie rod, sway bar links and cv joints as well as the front drive shaft are all fine. The noise is definitely coming from the top end of the pitman arm or higher. What it could be or how to fix it? I have an 03 6.0l f250 with a 4 inch lift all new springs and new sway bar

The last couple of weeks a new clunk has appeared on my F350, 6.2 CC LB FX4. If I've been parked for a while, when I drive off, within the first 30 yards or so there's a clunk. Seems worse when I've turned sharply out of a parking spot. Sounds like the rear diff or drivetrain... I have a locking rear diff. Is this engaged or disengaged while "at rest"? Could it be that its slow to unlock when I start?

I have a 2002 F-250 7.3 Powerstroke 4x4. My truck has developed a "clunk" for lack of a better term when accelerating from a dead stop. It is not a shudder as it only happens once within a few seconds of depressing the accelerator and then goes away until the next time I stop moving.
It feels like either something in the drivetrain is not engaging right away, or something is releasing, like a stuck caliper or something. From the way it feels and what I've read so far about the TC/Trans, I'm assuming it is something worn in the drive-shaft/rear diff.
But it needs brakes badly (already have all new rotors & pads ready to install) so maybe a caliper is sticking when depressed and then popping loose under initial acceleration? I think this is unlikely but possible.

I had a pretty good clunk going on and found the passenger tie rod was shot. The rest of the steer components looked fine. Fixed it and still get a nice bunch of clunks. Went over the steering again with someone rotating the wheel and didn't notice any crazy movements. The drag link twisted a bit but the joints looked solid compared to the tie rod which was completely shot.
So I decided to dig into it today. Looked again and nothing. So I took it into my back yard to drive over some humps left from stump grinding. Clunk, clunk, clunk. I stuck my head out the window and wouldn't you know it the sound seems to be coming from the rear! Took a pry bar to parts like the sway bar links, shocks, etc.... can't detect anything. Maybe a u-joint? Gotta dig in I guess.
Also my rear springs creak like nothing I've ever heard. Dirt roads it's just creak, creak, creak.
