What you should do is calculate your wheel revolutions per second and driveshaft revolutions per second at the speed where you experience the vibration. It's best to break out your spreadsheet for this. You will have to account for the specific tire you are using in order to calculate...

Best thing to do is perform a frequency analysis at the speed you are feeling the vibration the most. This way you can determine the source of the vibration (normally wheel and/or driveshaft). There are many phone apps that work quite well for this that utilize the accelerometers in your...

That is crazy logic. So if your truck is behaving the same as the other defective Rangers on the lot, "there is nothing further we can do"

Normal characteristic of the truck is to vibrate........ Nice one Ford.

I have been on back order for a driveshaft since late November 2020. I'm supposed to finally get my part allocation next week. I had a persistent vibration at high speed and the dealer found 1) one bad rim and tire (they replaced both) not within spec as it took excessive weight to balance and...

I think for some, the problem may exist from the start, but until you consistently drive at the conditions where the shudder appears, it may not be noticed initially. Also, the faster the acceleration, the more pronounced the shudder appears. Do those that accelererate very modestly made not...

No, most are seeing this at stock ride height. Dan

Can you send me info on your best pricing? Thanks, Dan

Mine was very consistent. I'm still waiting for a replacement drive shaft since mid Dec. I elevated through customer support to see if they can help expedite. The wheel and tire that was replaced took care of the majority of the vibration. Dan

I've got the stock 18" wheels that are part of the Lariat w/sport package. Road force balancing is where pressure is applied with a roller to simulate the truck weight on the tire. This more accurately reflects the balance under actual use conditions and can be affected by small changes in...

My truck has been plagued with both the start-up shudder as well as a high speed vibration. For those that have been following my previous posts, I have an update. Previously, I had been to the dealer 4 times in an attempt to eliminate the shudder and high speed vibration. It got to the point...

How much gap did you have between the wheel center bore and the hub? Dan

And why should he sell it? Some of us plunked down a fair amount of cash and happen to like the truck otherwise. Perhaps Ford should get off their collective asses and figure out what the hell is going on with these trucks.

My feelings exactly. I filed a complaint with customer service after the first four or five attempts at one dealer did not fix the shudder at all. Their response to me was "take it to another dealer". I was really not in the mood to hear such a brain-dead answer. But, just to comply with...

Yep, there's several here that have already gone through the TSB with limited or no improvement (I'm one of them as well) Dan

Ok cool. Let me work on this and see if I can get something to you. Thanks, Dan

According to my phone........ "The standard Slow-motion mode allows you to record all sections of a video at 240 fps. ... The Super Slow-mo mode, on the other hand, lets you record approximately 0.4 seconds of video at 960 frames per second with 12 seconds of playback." So it appears my phone...

Don't have an iPhone but my Samsung will record in super slow mo. How long of a video do you need, just a certain amount of frames? Dan
