    Some 2021-2022 F-150 Raptor vehicles built on or before 16-Jun-2022 may experience a clunk, thump, and/or rattle noise from the front and /or rear when going over bumps. This may be due to a concern with the shock absorbers.

    Refer to Workshop Manual (WSM), Sections 100-04 and 204-00 to perform the appropriate noise, vibration and harshness (NVH) diagnosis and inspections. If diagnosis leads to a shock absorber, replace only the affected shock absorber(s).

    I had to split it up due to size
    Hello @FordTechOne

    I am having issues with my 4X4 always that I start up my truck 4H engages by itself but the 2H light remains, after 7 minutes it disengages and it starts working normally. I used FORSCAN and my ECU sends the signal "NO" to the IWS which remains in "YES" but it won´t follow the command even that I tried to control it and press "NO".

    How are you determining its in 4WD? As mentioned, IWEs will remain engaged after startup for a few miles. That means the axles and front driveshaft will be turning during that time. The TCCM will likely ignore any scan tool IWE solenoid commands due to the start up strategy.

    Hello I’ve seen you on a lot of posts and you seem to be knowledgeable about our trucks. I have a question about the Gen 1. When shifting from gear 1-3 there’s a buzz like sound, my question is, is that normal? It’s noticeably louder when the ac is on. I’ve own it for a yr now. Any insight to what it might be? It’s a servo like buzzing sound.

    Hello, does the noise start immediately after shifting into drive (1st gear) or only once you’re moving? Transmission Shift Solenoid A is On in gear ratios 1st - 4th, so if it’s only occurring in 1st - 3rd, it’s not likely shift solenoid related.

    Thanks for the reply. Only once I’m moving. I’ve watched a few videos on YouTube of Gen 1 Raptors and I’ve heard a similar buzzing sound whenever they’re shifting. Whenever you get time May you please watch a YouTube video Specifically a video by Kevin Bridges “We put a Corsa exhaust on the Raptor”. Skip to 6:40 and listen to a sound on 6:42 when his truck shifts. That’s the sound my truck makes.
    Can you tell me if there is a way to just have 4H in normal mode in a 21? My 19 I could just turn the knob, I can only find Modes on the 21 4A in slippery mode, allows you the briefly spin before it kicks in. I have a long steep hill to my home

    I just looked in the owner’s manual; if you push the 4H button on the top right of the drive mode dial it won’t go into 4H?

    I read that probably 6 times, then reading your response I ran out and realized those are buttons! Crap, thank you it works!
    What are the new cam Phazer #. I seem to remember Q or something?

    There are 2 different part numbers (intake and exhaust) but the newest version of both end in suffix “CD”.
    The nut had not been previously removed and was a Nyloc flange nut. The threads looked "OK" and went together smoothly. I wonder how long it was loose. Thanks for the reply.
    I have a question.
    We were out at the Mojave Road and my friends 2020 Raptor SCAB had the UCA ball-joint nut come off. I found the nut and installed the UCA. Is there any "standard" repair on that type of failure or is it open to the Tech?
    I would NOT fell comfortable with just retorquing the nut.

    Was the nut previously removed? The factory nut has a nylon insert; it should never loosen up on its own. If the threads are undamaged, the proper repair is to replace the nut and torque it to spec.

    I've had these start to walk off on a couple trucks when we have been out west. We would check them regularly.
    My engine blew at 91K Miles. Told a valve broke off and went through the cylinders into the block and turbos. Luckily it covered under my 100K Ford warranty. The dealer says there are no complete engines available so they are ordering a long block and all the other parts separately. My question is are the techs specifically trained to build an engine as well as the factory ?
    FordTechOne

    Yes, technicians are trained in engine disassembly/assembly. However, there is no “building” required with a long block; it includes everything except for the intake/exhaust manifolds, fuel system, and accessories. You will never get a complete engine under warranty because it’s not necessary when the existing components can be reused.
    Started a conversation with you but not sure if you got it so I started another one.

    Sorry if it's a duplicate.
