It's been posted several times that some new vehicles had Perma Seal installed in the tires, which can cause serious vibrations, at speeds over 65mph, due to accumulation of the gel in one area. The fix reported was to swap the wheels and tire with ones that do not have the flat repair Perma Seal installed.

Hi All,

i know its illegal to drive at 80mph or above and it does not happen often, but when the flowing traffic is over 80 on a 70 limit the new 2023 Limited with less than 1000 miles on it is vibrating. I can feel it on the steering and the floor.

Went to the dealer Sheehy Ford Gaithersburg and they said they cannot test anything more than 65mph and below 65 its fine. So they are not going to fix anything as they cannot replicate it.. What happens if this vibration slowly starts popping at lower speeds in the future?

Any advice will be greatly appreciated.
Do what i did and you drive the car with the tech. I had the tech grab the steering wheel and he could feel it. But they still didnt fix it said they road forced balanced and said it was road sensitivity from the 22" wheels. Just short of chocking this SOB - i told him he was an idiot and i went to another dealer and they are working on it

Vibration is one of those things that is very subjective, so what may feel like "a lot" to one person may feel like "nothing" to another. People also have different expectations, it's not necessarily logical to expect a vehicle as huge as an Expy to ride a smoothly as, say a Lexus LS.

My 2007 navigator vibrated at high speeds over 65mph. Road force balancing fixed the issue

That is so very true. Sometimes my wife can feel the vehicle vibrations I'm chasing and sometimes she can't.

Our 2004 had a very poor set of Continental tires, one was terribly out of round. Finally the regional Ford mgr just gave me a check to get my own tires with my word that I would not come back to a dealer about the tire issue. I knew how to balance tires and they didn't like it. The funny thing is it wasn't noticeable for like 2 couple months after purchase. I think clearly things change, but some of it may be that we have to get used to a vehicle before we notice abnormalities.

This is common on these trucks. It's all over the 4th gen forum. The common fix is getting all tries road force balanced, however the trouble is getting a shop to do it for you.
Completely agree. Discount tire does RFB and my Ford dealer does as well.
