This is the third rear axle bolt that has broken on this truck. It was found during a flat repair.

The the head of the rear axle bolt on the passenger side has sheered off. This is the bolt which holds the rear axel shaft connected to the brake assembly. This broke at least 2 weeks before it was officially discovered on August 9th of 2022. Ford has yet to provide a clear date on when the replacement part will be provided. They claim the enter axel shaft needs to be replaced and that the replacement SHOULD come off of back order at the end of October 2022. They told me this same thing back in August, that i would have my part by the end of August. The internet is ablaze with this issue.

On 10/22/2022 I took my truck in to the Ford dealership for oil change and tire rotation, upon rotating the tires the technician found the axle bolt on the rear drivers side was sheared off and part of the bolt was still in the axle. The dealership kept my truck and ordered a new bolt and gave me a vehicle to drive. My truck has 26,744 miles on it. I am concerned after reading many posts on Ford forum this will continue to happen after warranty expires. Some of the posts stated Ford dealerships were replacing the axles. Please advise thank you

The passenger side rear hub bolt sheared off. My mechanic found it while rotating my tires. I called the Ford dealership and they advised me that I am not to drive it and have it towed for repair. I tow a travel trailer which is within the limits of the truck and I'm thankful that it was not a catastrophic failure that caused the wheel to fall off and cause an accident.

Vehicle lurches forward when transmission is in drive position, when stopped with foot on the brake. It is very forceful and feels like being hit from behind. It could easily cause a collision with a car stopped in front of my vehicle.

I took my 2021 F150 Powerboost with Max Tow package into the Ford dealership for service and to inspect a noise coming from the driverside rear wheel. When the wheel was removed the source of the noise was confirmed as a sheered-off axle retaining bolt. I was told by the service department the truck was unsafe to drive. I am unsure if this nut holds on the wheel hub assembly but I'm guessing it could lead to loss of power in the affected drivewheel or loss of the wheel altogether. Upon doing some internet research this is quite a common issue with the 3/4" floating axle that was new to the 2021 model year for the Max Tow package. This is an issue with the drivetrain of the vehicle that could lead to safety issues for the occupants and others and should be recalled with upgraded/redesigned parts.

When I come to a stop, my truck will try to lunge/jump forward after a few seconds. It has been happening for a few weeks now. This could result hitting another car in front of me or potentially a pedestrian if I am stopped at a cross walk. I took it a dealer yesterday and they confirmed the problem. They attempted to reprogram it and said it fixed it. Later that night and again this morning, it did it again.

The rear axle bolts sheared off for unknown reasons. The symptom was a metallic rattling noise from the back of the vehicle - the noise was pieces of the axle bolts bouncing around inside the wheel center cap. The bolt in questions holds the rear axles in place. Vehicle has been at dealership for 2 weeks as they said it was a common problem that is a safety issue. Said it was possible for one or both of the rear wheels to fall off if I had continued driving it. Obviously losing one or two wheels is a huge safety concern. My dealer said he has seen this exact issue 4-5 times on similar trucks. Vehicle is less than 9 months old and has less than 13,000 miles on it. Vehicle is being repaired under warranty but using the same parts.

A noise being heard any the rear-end of the truck. Upon taking the rear tire off for investigation a bolt head was noticed in the center of the rim. This bolt came from the axle. The bolt in question holds the axle in place, if driven for a great distance then a chance of the axle floating towards the gear which could have caused a major safety concern for the occupants of the truck and anyone on the road Truck is currently at the shop, but dealer is replacing parts with same components. No root cause has been found to address concern. Other side of axle could reflect the same condition

I brought my truck in for routine maintenance oil change & tire rotation and was notified by the dealership that the right rear axle bolt was broken off and that the axle needed to be replaced and that it wasn-€™t safe to drive it until it was replaced well here-€™s my problem I didn-€™t know it was broken or unsafe to drive and had I not brought it in for the oil change early I would still be driving it like that this is a serious problem which could result in a loss of control and accident I-€™m not the only one that has had this happen I-€™ve researched it a little and found multiple people on an F150 forum that have had the same experience

There is a fairly common issue where there are bolts at the end of the rear axles (P/N 19S426) have the bolt head shearing off and rattling around inside the wheel. I had one such broken bolt. The issue is large enough that hundreds of owners are reporting this on Ford Truck forums, namely on the 2021 Ford F-150 Powerboost with the Max Tow Package like mine. Ford needs to recall this.

Passenger rear axle bolt broken. This seems to be happening only on Max tow equipped vehicles, LOTS of them.

- Warwick, NY, USA

The bolts that holds the wheel assemblies to the axle have both broke off. Right side in February and the left side in September. It allows the wheel and brake rotor assembly to move in and out on the axle shaft. The only thing holding the wheel on the truck is the brake rotor assembly. It was found during a tire rotation.

9.75HD Rear axle retaining bolt sheared off.

No part failure confirmed by Ford. Transmission has very hard downshift at highway speeds from 10th gear to 8th gear under moderate throttle causing the rear wheels to chirp. Had this happened during cold months it could have caused me to spin out. Ford states transmission is normal yet previous TSBs show consistent issues with the 10r80 transmission from My 2018 and up in regards to harsh, delayed shifts. No warning lamp other than traction/stability control flashed. I have had the dealer look but was told it is normal as with other drivers. I can't understand how chirping the tires on a down shift under moderate throttle can be considered normal.

Rear differential, passenger side axle bolt broke off. I removed the right rear wheel after hearing a metallic noise while braking to inspect, as soon as I removed the wheel a broken head bolt and washer fell out and you can clearly see the other piece of the bolt is still in the axle shaft. I am not sure if this bolt breaking off could cause loss of wheel or axle. But now my brakes are making noise, I believe as a symptom directly related to this issue. I looked up 2021+ F150 forums and customers with this max trailer tow axles are experiencing the same thing. I took the vehicle to the dealer today to get this inspected and am awaiting an update. The only indicators of a problem was loud metallic noise while braking, and a slight ringing sound while driving without braking. It was all sounding in the rear of the vehicle.

When in regular use of this hybrid Powerboost F150, the truck lurches forward on electric motor power as if you just got rear-ended. This happens every single time you have to come to a stop for more than 5 seconds. The only way to avoid this issue is to drive in"tow/haul" mode which keeps the truck's engine running. This defeats the purpose of a hybrid truck, and you have to remember to switch the running mode from normal to the haul/tow mode. This lurching had to be causing extra wear and tear on the drive train parts. Apparently the problem is a faulty "Transmission Fluid Auxiliary Pump". Many of us on the Ford F150 forums are waiting on our dealers for this back ordered pump. Apparently Ford continues to build vehicles while falling to provide a replacement pump" I am concerned as to the design of this pump as well. My"new" truck only has 7800 miles on it, a little over one year old, and the pump is defective. Is this going to be a reocurring problem" This is a safety issue and should be addressed ASAP. Thank you for your attention to this matter..

My 2021 Ford powerboost Lariat lurches forward when at a stop in normal drive mode, it feels like someone rear ended the truck.This is a safety hazard if I don-€™t have my foot pressed hard on the brakes I could be launched into on coming traffic or hit someone crossing the street.

I took truck in for an oil change and the service sept advised me that during the tire rotation they discovered the Axle bolt sheered off of driver side rear axle from normal use of truck. Dealer said ford advised them that the truck must sit till the axle is replaced due to it being a safety hazard to drive. My truck is now sitting at dealer waiting for a replacement axle.
