3.6.2021 - Ford F150 purchased at Battlefield Ford (Ourisman Ford), Manassus VA / registered in CT 7.27.21 – inspected by Torrington Ford, Torrington CT for rubbing sound front left side, nothing found / 6,325 miles 2.10.22 – inspected for same issue / nothing found / 16,000 miles 7.27.22 – inspected for same issue / nothing found / 24,000 miles 12.24.2022 – “Catastrophic failure” of front differential / 34,369 miles. On Christmas Eve 2022 myself, husband and son were driving to family in NY when the truck very quickly started to make a severe grinding sound, became unable to steer, loss of control, and started to produce smoke & fire under the hood. We immediately stopped and got out unharmed. Fire was dripping out of the bottom of the truck and smoke/fire under the hood. We were lucky. Firetrucks came but were unable to do anything. The truck's wheels completely seized up - the tow truck had to skid it onto the flatbed. Repaired at Simmons-Rockwell Ford, Hallstead, PA. Complete new front differential and damaged parts in proximity to the failure (pinion gear, axle shaft, etc). 12.16.2023 – Again hearing a sound in front left side while driving; bring to the shop for inspection. Shop confirms front differential is failing again, per Torrington Ford, (where all maintenance and repairs were completed, except for the first failed front differential in PA). Advise not to drive for safety reasons. 52,922 miles. With both front differential failures - no warning lights or messages. Symptoms - a slight rubbing/grinding noise in the front left side of vehicle; “rough” sound while driving. 1st front differential – inspected at 6,000 miles, 16,000 miles, and 24,000 miles. Failed at 34,369 miles. 2nd front differential – inspected at 52,922 miles, failing differential, advised not to drive. Dec 2023 – Buy-back claim filed with Ford Motor Co. Denied - "outside of the 18-month warranty period for VA Lemon Law". Clearly, safety is not a guiding tenet for Ford Motor Co.

My truck has the Maximun payload axle upgrade. The axle bolts on the end of the shaft have broken. I first notice squealing sound of metal from rear of truck. I searched on line for the symptom and found the problem. I then removed passenger rear wheel to verify broken bolt. I took my truck for service to Morries Grand Ledge Ford in Michigan. They verified the problem, told me it was not safe to drive and have ordered parts. They also informed me that the defective axle is not covered by recall on my vehicle. The service representative did confirm that there are recalls for the same axle but not my vehicle.

Intermittent squeaking noise upon brake tip-in started at about 17,000 miles but performance seemingly unaffected. Then at 21,000 miles noises from became louder and prevalent at acceleration and braking. Noticed issue on Ford F150 14th Generation online forum about axle bolts shearing particularly for those vehicles with Max Tow package and that there was a Customer Satisfcation Program 22B34 to deal with the problem. Inspected hubs and found bolts sheared on both sides. Truck at dealer for warranty repair under the CSP.

Planned one week, 1,400 miles roadtrip along pacific coast during memorial day weekend. Before starting our trip I went to rotate the tires and upon removing the rear passenger side wheel a bolt and metal gasket fell out. Issue: Center bolt that locks the brake assembly to the rear axle shaft was sheared off with remaining half stuck in the axle shaft. How was your safety or the safety of others put at risk?: The truck would have been loaded for our week long roadtrip up North. On the way back we were going to tow our 5000lbs trailer. This bolt would have impacted the braking ability, cause damage to the rear axle assembly possibly resulting in an accident. If I didn't rotate the tires before leaving who knows what could have happened especially if I was towing. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Vehicle is currently at a Ford dealer for axle shaft replacement. The service manager had a broken bolt from another vehicle and asked me is this what happened? There are hundreds of F150 owners complaining about the same thing on various forums. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. I'm glad it didn't get to that point. But from all users that had this problem and got replacement axle for what seems like defective bolts I would hope Ford would voluntarily inspect and issue a recall. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No fault lights but I did hear faint grinding sound when the windows are rolled down. I guess the bolt was spinning around in the wheel.

Both rear axle retaining bolts snapped. The only thing holding the axles in was the brake rotors and calipers. Had they not started squeaking and grinding, I would not have known those critical bolts had broken! At the dealership now being repaired. With the same faulty methods and parts. VERY common problem for the F150 Powerboost with the Max-Tow package.

In May 2022, the passenger side right rear axle bolt sheared off creating a squealing/grinding noise from that wheel. The only thing holding the wheel onto the axle were the brake caliper bolts. The repair involved a new axle. In early Sept 2022, the driver side rear axle bolt sheared off with the same results. The vehicle is now in the shop waiting for the parts to arrive. Dealer advised that this is a serious safety issue and requested that the vehicle be towed to the service center.

The wheel hub axle bolt sheared off under normal conditions-dealer was unaware this was even an issue and told me the bolt they found within my wheel assembly and its attached washer was picked up off of the road (road debris) that they removed it and it would not grind anymore. I did basic research as an uninformed consumer and within seconds learned this is an issue on hundreds of other power boost pickup trucks. There is extensive documentation online regarding this issue. I called my dealer who has yet to respond to me. This is a major safety issue-the only thing holding the wheel on is the brake caliper. With as many documented cases as I can easily see online-the fact that my dealer is not aware of this indicates Ford has done nothing about it. This should be a recall. Please advise.

Left rear axle bolt sheared off into the wheel spontaneously. It is available for inspection. . Currently at dealer right now for repair. Dealer indicates vehicle not safe to drive due to potential for loss of wheel, brake components and wheel hub/axle during travel. I have not experienced loss of a wheel while driving luckily. There were no warning lamps/messages etc. No symptoms of the problem prior to failure were noted. The only sign of an issue was loud squealing from the left rear wheel when brakes were applied or when turning the steering wheel slightly either right or left.
