Ford Super Duty (1999-2016) :: F350 - Loud Clacking Clunking Sound Coming Directly From Trans
Feb 12, 2014
With the tranny in neutral and clutch out is when it is the loudest. With the clutch in their is 0 noise. The sound is a spinning clacketing sound best I can describe. The clutch is 2yrs old and was installed by a local shop using all OEM parts, the fluid level is perfect and looks brand new. The sound has come on gradually over the past 6 months but now can be felt thru the floor at the top of the gears as a rumble. The funny thing is that their are no performance issues like grinding,popping out of gear,hard shifting,etc.
This is not rolling gear mesh it is very loud clacking clunking sound coming directly from the tranny, not the transfer case, nor rears or u joints. This is standing still. Sometimes it will be a little less loud if I roll to a stop in neutral with the clutch out as opposed to gearing down to a stop push clutch in goto neutral and letting clutch out.

So, I have this problem that comes back when the temperatures drop below about 20 degrees F. The truck is a 2012 F350 diesel with 15k miles and has done it since it had 3,000 miles on it. When turning in an intersection, or just moving the steering wheel left to right, it makes a clunking sound up in the front steering area and you can feel it a little as well. I have taken it to the dealer and they tightened the body mounts, but that did nothing. Once it warms up, the sound is gone.
This, coupled with the rear end clunking loudly over every bump and pothole when it is cold out, makes this truck a real noisy/annoying vehicle in the winter.
Here is a video of the steering noise, it is louder in person: [URL] ....

I thought there was a v10 specific superduty section like how the psd does, but my thread went in the "performance, engine, troubleshooting" section.
I wanted more exposure than that particular small viewed area.
I don't have a video of the noise, but my 99 f450 v10 5spd has some iffy noise coming from the front. I've read so many threads on this and they either end with "my motor had 1-2-3 bad pistons" or "my flexplate was cracked" and all that dealt with chain tensioners were never finished.
I know what piston slap sounds like (worked on many cobras and lightnings with forged pistons that had it) and have experience with bad wrist pins and broken piston skirts, and this noise doesn't sound like any of it.
Noise is a loud clicking/clunking/Detroit diesel idle noise. When you rev the engine up it doesn't lighten or get better, only worse as rpm goes up. Oil is terrible looking, I'll be getting that changed this week.
Story on truck. I've had this thing for 4 years with blown motor. I got a buddy that acquired a parts truck and he said it ran good. I dropped my truck off and he swapped the engine. I got my truck back running, but with this engine noise. He said it needs to get run some more and change oil.
I think it's timing tensioners, my buddy says it will come out of it, a mechanic friend says it's going to blow up "because they all do" and I don't really want to replace the engine again.
If it's tensioners, how big of a job is it. I have the cam clamps and crank stop and the ford tools to make sure crank and cams don't rotate while apart.
I'm just 650 miles from my truck and may need someone else to do the work. Which sucks.

My 11 cc lb 4x4 6.2 has a clunking/loose sound coming from the front end. It is prominent when going over small/medium bumps but not so much large bumps. I have had my local dealer and a couple local shops look at it and they all say everything checks out. It definitely seems like something is loose in the front suspension. I just put new Gabriel max control shocks on all four corners. I have no play in wheel bearings or ball joints. Tie rod ends also look fine.

I have a 2003 Ford F450 super duty xl. At first there was a loud clicking sound coming from under my dash. I charged the battery up and the sound went away but the truck will fire up but not turn over and start. I thought maybe it could be the relays but the clicking sound quit.

I have a 2002 F350 with the triton 5.4. For the last week it has been running like crap. I just did my plugs about a month ago. I don't know if it's a miss fire or bad fuel or I don't know what it could be. It's a popping sound coming from my exhaust and when it happens I lose power. It happens off and on. One second it will run fine and normal and the next runs bad. What it could be. Today I just changed my fuel filter and added STP octane boost and fuel injector cleaner. Haven't seen a difference yet.

I have a 1999 f350 v10 stock truck. It has plenty of power when it's cold out or raining or I'm on backrooms or highways but if I drive through town on a hot day the transmission kicks bad I have changed the fluid and filter, it also seems to shift at a high rpm from 2nd to 3rd. Unless I you let off quick and go back on kinda like engaging a 2 speed rear end. Does it need a bigger trans cooler or is the trans shot

2002 F350 Super Duty 7.3 Diesel.Transmission trouble. Came off interstate - took foot off throttle at yield and hit gas as turn was clear. Did it fast and felt like hit wall. Immediately lost transmission engagement. Trans did not reengage until below 20 MPH. Tried to speed up and disengaged at 20 to 25MPH - just free wheel - engine wine. Went to 1st gear and would come up normally. Shift to 2nd and could get up to 30MPH and probably higher - didn't push. Shift to drive and trans disengage. No trans fluid leakage and level looks good and clean. What to look for? 126K miles.

I have a clunking noise that I can feel directly under the floor board that definitely seems suspension related. It is getting progressively worse, it's not constant but it is magnified when hitting bumps, pulling out of driveways etc. I have jacked the truck up and tried to simulate the issue with no luck.

What this clunk could be?? in my truck in signature, 2003 F350 CCLB 4x4, 4" lift. its only low speed, on very light bumps. really does it when the truck flexes, like turning into an elevated driveway or something. driving me absolutely insane the last few months. it sounds like its coming from right under my feet
-removed front shocks and drove
-removed front sway bar and drove
-front wheel bearings are new and tight
-front leaf spring, rear upper shackle bushings are new (thought that was problem..no)
-front leaf springs and bushings are new, although i suppose its possible to have a bad bushing already
-removed traction bars and drove
-removed front track bar and drove, but going to try this again.
-all cab mounts look ok
-took out cab mount under drivers foot, and cut down the metal piece a little...read about it on another thread on here. no change
-made sure my gooseneck ball couldn't rattle
-steering box is new...thought that was it
-steering shaft is solid
-transmission mount bushing and crossmember feel tight
-lubed front driveshaft slip joint and it doesn't have any u joint play
-rear shocks seem ok but haven't removed them yet
-fuel tank is solid
-rear driveshaft has new carrier bearing and u joints, all is tight
-exhaust is not hitting anything
-u bolts all tight, spring bolts are tight
As you can see, I've been through damn near everything. my only thoughts right now is a possible bad cab bushing, or bad leaf spring bushing...as it sounds like its right under my feet. and when you flex the truck, it makes all sort of popping and clunking noises. i had the truck on my buddies lift and we went under it for an hour yesterday looking around with no luck. only thing i found was a bad traction bar bushing but we removed them and it still does it..
Most noticeable at the end of the video...it sounds exactly like a bad sway bar bushing but that's not it...

The trans temp guage on my '08 F-350. V-10 started acting erratically, and the wrench icon popped up on the display. i crawled under the truck to look for the sending unit and it's lead. i assume that i found the lead. it is encased in a corrugated sleeve, and appears to be a vaccuum type tube and boot connector? the boot still had a small round gray cap plugged into it. it appears that the cap was never glued (go figure) upon assembly. i have tried to reach up on top of the trans to find the sending unit to figure out the best angle of attack. i can barely touch it with the tip of my finger. going with mechanical guages is out of the question at the moment, so i'm wondering can it be driven any distance this way, AND any schmooze tricks developed to get at the sucker without dropping the cross member or exhaust????

I have an isspro sensor that I need to install on my 4r100. I have it all installed except for the actual sending unit. My question is where is the best place to put it?
I've watched multiple YouTube videos and it seems a lot of people use the test port on the driver side above the linkage. I found out the hard way that it is a very poor choice of location. A lot of people say that the best way is to drop the pan drill a hole and weld in the bung? I was wondering would it be possible to put it on the "out" line on the transmission oil headed to the cooler? 01 f-350 7.3

I replaced the sensor on top of the water pump and the gauge still doesn't work. I tested the gauge by unplugging and grounding out the wire and the gauge goes all the way up. What I can try next. I didn't get a Motorcraft sensor so I'm going to go get one of those tomorrow hoping the duralast wasn't correct even though it looked 98 percent identical to the original. 7.3 lite diesel.

Truck: 2001Ford F350 5.4 auto 4x4
Issue: Engine seems to free rev over 2500 RPMs. Barely hits 50 MPH. Revs fine in park, no power in gear. At 1/4 throttle it will move, but sluggish at best. Once you get around 2500 RPMs it stops accelerating and just revs. Does this in every gear, and gets worse the faster you go. feels like its stuck inbetween gears almost. No CEL's
Replaced: MAF, TPS, Trans fluid and filter, fuel filter, cleaned intake system, fuel system treatment, O2 sensors. Trans fluid was dark, but no burnt smell.
I'm about to pull the exhaust and look for a clogged cat.

I have an '06 F350 dually with a 6.0 diesel. I bought this used about 5 years ago and for the most part have loved it. i would always smile on the inside when i heard people bash the 6.0...i thought i got lucky....until today.
140k miles. recent oil change. all is swell...until this morning. Stick in key and turn it. glow plug indicator comes on...all lights come on for a few second....wrench, abs, dtc etc....wrench shuts off...glow plug light comes on...4 or 5 seconds later wrench light comes back on....turn key and NO CRANK.
All fuses are fine...starter cranks if i jump the solenoid...but it won't start. Miles to empty and everything else is just dashes hit the OBD and it says "engine sensor data error"/ "trans temp error" ...

I have a 2012 F250 XLT crew cab, longbed truck. My problem is wind noise, it seems to come from the windshield directly in front of the driver side. I plan to use some blue tape to cover the area to see if I can find the problem.

2012 truck, started making a noise today. I cannot tell what it is, but seems to be coming from the passenger front suspension, its a crunching/light clunking sound, happens when going over bumps, when the truck pitches one way or the other turning, and coming to a stop....
Truck has 6k miles, I did a quick visual inspection this afternoon, didn't notice much, but the sway bar endlink looked a bit odd though, not sure if normal, its gota little bend too it and seems to just contact the vac line mounted behind it, seemed unusual...
Maybe its its just one of the crappy rancho branded shocks is junk?

2002 F250, 8 inch lift w/ 37's ... Manual locking hubs ...
Ok so my truck has no issues in 2wd even with hubs both locked or when in 4x4 hi/ low with hubs UNLOCKED.
BUT as soon has 4x4 system is in action as I idle forward there's a massive clunking and binding sound like a sledge hammer bouncing off my front diff./ drive shaft. But there's no physical binding of any components that I can see! Just a rhythmic and consistent thumping.
When you turn the wheel either direction the sound intensifies. I even dangled from the side steps as my buddy rolled forward to observe the situation.

I have a 2007f550 auto trans with a flashing tow/haul light and a code of po791 coming up. Flashing light will clear in k/o position and remain off until placing selector in drive,after two feet or so of travel,an audible clunk and the trans acts like it is in third gear. Reverse is no change and highway will not shift into o.d. The iss "A" is listed as the culprit but ford doesn't list a iss a.

I have 99 f350 v10 4x4 and trans shifts great under light rpms but 2-3 shifts very hard. At wide open from about 35 mph it will shift down and take off like a bullet but wont shift until I lift my foot and then it bangs hard from 2-3. All other gears are smooth. I did some searching and have found some threads saying it could be an accumulator spring that is broken? Truck has 115,000 miles on it. love the truck but want to fix this before it does some damage.
