Unfortunately, they didn't find the culprit. The shotgun approach certainly brought in new parts that are tighter and not worn. But which fix had the most bang for the buck? If the steering damper was still tight, as he said, then that wasn't it and the new dual steering stabilizer setup was a cost that could have been avoided.
Nonetheless, it was an instructive video. I learned how the additional caster is set among other things.
He likes to spend your money for sure! I do agree the dual SS was overkill but at least he fixed the problem unlike Ford. I also found it interesting that the tie rod is the same part # they been using since 2006.
Fixing the problem is the goal. If I had recurrent death wobble, I too would be saying, "Just fix it. I don't care how."
Surely there are aftermarket parts that are tougher than the OEM parts.
I don't mean to bash those guys but saying that only OEM brake rotors/pads should be used because of the automatic braking seems to discount all the math that goes into automatic braking. It also assumes that aftermarket rotors/pads would have a longer stopping distance. While I have no insight into how Ford programs the automatic braking, I have to wonder if they assume that every vehicle that rolls off the line brakes exactly the same. Ideally, each vehicle would brake the same, but the on-board computer is smart enough to figure out distance between objects and the brake force necessary to avoid an accident, no matter whose rotors/pads are on the truck.
Stock 2017 with 28K miles. Made an appointment to have my tailgate recall taken care of and before the appointment I had the DW. When I delivered the truck for my appointment, I told them do the DW and handed them the TSB. I picked the truck up and they said they replaced the steering stabilizer as they “tested” it and it failed. They made no mention of changing anything else and they did not do an alignment. The truck seems to drive much better.
2017 F250 with 6.7, SRW, Lariat FX4. Stock everything, no mods, no changes to drive train or suspension. I experienced the DW at ~18K miles going ~70MPH, I wrote it off as a single occurrence. About a month later it happened 3 times in 2 days, once at speeds <20MPH. I took the truck to the dealer where it was purchased and they had it for almost 4 months "waiting on parts". I finally got the truck back and the steering is noticeably tighter and no DW since (now at about 21K miles). Supposedly all they did was change the steering dampener however I am not 100% confident that is all that was done considering how tight the steering feels now. Time will tell if the DW comes back...
