Drive Line Vibration @ 75MPH+

[Capecod]

I have Hankook tires not Pirelli but they suk too!! LOL : ) They replaced two of the four original tires and still shimmy/shake. With them replacing your driveline/driveshaft do you think that it being off will effect the differential/transmission/etc... ? All the math matters, I believe. IDK...

What I did to diagnose myself.... Get cruising down the road at speed until vibration occurs...put transmission in neutral.....see if vibration is the same....if it continues the same I would think not the driveshaft and more than likely a tire issue. My truck the vibration issue drastically was reduced when shifted to neutral. I had both tire and driveshaft vibrations. Two separate issues. First the driveshaft was replaced and the tires afterwards. It was a battle and headache to get this done but worth it..

A failing U-joint may produce a load dependent vibration. The above method may not reveal a failing U-joint.

These are brand new vehicles where the problem exists day one. What do you suggest ?

The problem may be a U-Joint. Certainly there are other mechanisms. How do you diagnose a U-Joint? Frankly, the quickest method is to change them out unless you have a sound sensor you can attach (not common). There's one on each end of the propeller shaft. I've done much of the work on my vehicles over the years and when I started getting the symptoms you show (after the first time it happened to me), I just changed them out. Not a difficult job with the correct tools. I'd expect a new vehicle to not have such a problem, but every so often one gets installed and damaged during assembly.

They used a vibration analyzer and sent report to Ford. Ford recommended zero repairs or solutions, said nothing was out of specs. It is total crap as it shakes horribly like a 40 year old truck that all tires are out of balance.

Same issue on my 2024 Plat. I went from a 2021 limited (same basic truck), so I know how it should drive. I went down the rabbit hole to the end and Ford says it is within specs. Apparently within specs. is a worthless statement.

Sorry to hear ..... Sad but true. The way you will get it fixed is spending your own money going to independent shops. You can have your driveshaft balance checked at a specialty shop that does this work. Ford just replaced my driveshaft. The tech told me they don't send driveshafts out to have the balance checked. Investing in different tires and have them road forced balanced at a tire shop other than Ford dealer. Have the tire shop road force balance your existing tires and get their opinion on the tires quality. There is no fix for tires that are way out other than replacement. My dealer told me Ford absolutely HATES warranty claims on tires. Difficult to get them replaced. Best of luck. Total BS on a brand new vehicle.
