Ford F-350 SD knocking problems

Filed Oct 30, 2026 · Engine · WA

I am the owner of a 2022 Ford F-350 equipped with the 7.3L pushrod V8 engine. My vehicle suffered a premature, catastrophic valvetrain failure involving severe wear and failure of the camshaft and lifter rollers. The dealership diagnosed the issue and performed a complete replacement of the camshaft and lifters under warranty. While the valvetrain components have been replaced, I am extremely concerned about the long-term structural integrity, safety, and reliability of the engine. The mechanical failure of the lifter rollers and camshaft lobes sheds an immense amount of fine, hardened metal debris and shavings directly into the engine oil supply. This metal contamination circulates through the entire oiling system before reaching the oil filter, presenting a severe risk of scoring the cylinder walls, damaging the crankshaft/connecting rod bearings, and clogging oil control solenoids or passages. Despite the component replacement, underlying engine damage or accelerated wear to the block and lower-end bearings may have already occurred due to this metal debris. This defect creates an ongoing risk of sudden, localized oil starvation, loss of engine compression, or catastrophic engine seizure while operating at highway speeds or under heavy load, presenting a clear safety hazard. I request that the federal safety agency ensure its ongoing investigation fully accounts for late-model consumer trucks like the 2022 F-350, and pushes Ford to provide extended powertrain warranties or full long-block replacements for vehicles subjected to internal engine metal contamination from this valvetrain defect.

The vehicle is a 2022 Ford F-350 Super Duty equipped with the 7.3L Godzilla gas engine. This vehicle has experienced recurring, catastrophic internal engine component failures involving the lifters and camshaft, resulting in severe powertrain malfunctions while operating under load. The original factory engine began demonstrating progressive valvetrain symptoms and mechanical ticking at approximately 36,000 miles, which ultimately resulted in a complete engine failure and replacement under warranty at 50,000 miles. A factory replacement engine block was subsequently installed under the Ford Service Parts Warranty. At approximately 75,000 total vehicle miles, the replacement engine began demonstrating the exact same symptoms and lifter failure characteristics. The dealership has officially diagnosed this second engine failure under the manufacturer's Technical Service Bulletin (TSB). While actively hauling a trailer at highway speeds, the vehicle developed severe engine misfires and a pronounced mechanical ticking noise from the valvetrain, creating an immediate and alarming concern of imminent mechanical failure. The vehicle's onboard diagnostics generated critical powertrain malfunction alerts, which were broadcast in real-time via the FordPass application. This recurring failure represents a severe safety hazard. A high-risk valvetrain failure that threatens an immediate breakdown while a heavy-duty truck is actively trailering commercial or heavy loads creates an extreme danger of a high-speed highway collision or roadside emergency. Furthermore, the repeating nature of this failure indicates a systemic manufacturing or design defect in the 7.3L valvetrain components, which presents an ongoing safety risk even after a full engine replacement has been performed.

The truck has a clunk in the steering when pulling trailers and does not do this when not laden. The vehicle has only 2,480 miles on it. I was told at the dealership that this will not be fixed because they are not able to replicate the issue. There is a TSB on the issue: SSM 53169 2023-2024 F-Super Duty - Popping/Thumping/Clunking/Knocking Noise From The Steering Column - Built On Or Before 12-Jul-2024 The vehicle was built prior to 12-Jul-2024.

The contact owns a 2016 Ford F-350. The contact stated while driving 60 MPH, there was an abnormal knocking sound coming from the engine compartment. The vehicle was taken to the local dealer where it was diagnosed and determined that the cylinder was not operating as needed, and there was engine damage. The vehicle was not repaired. The vehicle was previously taken to the local dealer, Summerville Ford (9700 Dorchester Rd, Summerville, SC 29485); where it was diagnosed and determined that there were metal shavings in the fuel system in the high-pressure fuel pump. The vehicle was repaired; however, the failure recurred. There was black smoke while driving and the check engine warning light was illuminated. The contact stated that the turbo charger, body mounts, and coolant pump were replaced; however, the failure persisted. The manufacturer was not yet contacted. The failure mileage was approximately 82,800.

Engine had 77K miles on it and began knocking while towing a 5th wheel trailer. Took vehicle to diesel mechanic and was informed of rod bearing issues with the 6.7 powerstroke diesel. The entire long block had to be replaced due to poor design issues which were corrected with he new long block. Vehicle was out of the warranty period despite only have 77K miles on the engine and all maintenance was up to date.

My vehicle started to shake uncontrollably at 50mph when driving. Research online indicated what people call a "death wobble". I contacted my local Ford dealership multiple times to see if my repair would be covered by Ford. On November 8th, 2022 I turned my truck in and on the 11th I was told what repairs needed to be done. On November 21st, I picked up my truck and parked it at my house. I drove less than 40 miles locally with speeds never exceeding 50mph. On December 6 I began a work trip to Nashville from Killeen Texas. 20 miles into my trip my truck did the "death wobble" with me going 70mph. Two hours later it happened again. I drove all the way to Nashville going 50mph and experienced the death wobble about 8-9 times. Now my engine has a ticking noise that I am certain came from the unsafe, violent, and terrifying shaking of this massive truck.

I experienced a violent shaking that happened to the front end of my 2017 Ford F350 Super Duty truck (with 25600 miles on the odometer). It typically occurs at speeds over 50 miles per hour. It's also happened after going over bumps or grooves in the road. I brought my truck into a local repair shop because an appointment with my local dealer wasn't available until Mar 16th (60 days). The repair shop shared with me that they noticed abnormal wear and loosening of the track bar bushing, damper bracket, ball joints, control arms, shocks and struts. Additional they shared its not safe to drive the vehicle in it's current state. Ford has yet to issued a recall for this hazardous defect. Lastly because they haven't admitted to the underlying issue, OEM parts are my only option. This leads to me spending thousands of dollars with no resolution. I very well could be driving a ticking time bomb again.

Vehicle developed knocking in front end at 5,000 miles. At around 10,000 miles began uncontrollable shaking in the steering when hitting a bump at 75 MPH on highway. This would stop by slowing down to 40 MPH. This continued until the front stabilizer was replaced by ford at around 15,000. Vehicle now has 20,000 miles on it and has again started shaking uncontrollably as stated before. Fords fix is to replace it again with the same part that has already failed twice. I have heard of the same issues from other people is similar makes and models.

At times while driving at 45-60 miles per hour and while in 6th gear (automatic) after the "cleaning exhaust filter" message comes on when it cleans the exhaust twice within a 100 miles, the engine will shake and knocking/spiking noise after the second cleaning. This happens intermittently and I am unable to recreate the problem at the dealership. It doesn't happen all the time but when it does it feels like you have a loose wheel and it will jerking backwards and forth. Ford seems unaware of this problem and has no remediation on how to fix the problem. This started around 8000 miles the truck has 32,000 miles now.
