TSB 20-2277 2019-2020 Ranger - Shudder/Vibration When Accelerating From A Stop

[navsnipe]

Or… get a Ford tech to measure your operating angles and report to Ford Cust service. That was going to be my next move. A quantifiable proof that it’s out of spec so they’ll have to do something.

I've been through that whole process starting in September just after i bought my Ranger with tsb being done three times with the last at a different dealer. I was pretty active on this thread with the details. I'm just tired now. I do a ton of stop and go on my commute and just want smooth.

Does yours have the shudder?

Actually it does but so slight I don’t think about it. With a 100 lbs in the bed it’s gone.

I've succumbed. I called my dealer today to facilitate warranty repair for this issue, among others. I'll update the thread with our findings, good or bad. I adore the truck so I'm hopeful a resolution comes forth.

I put a 70lb sand tube bag in the middle of the bed length-wise. The shudder is tamed quite a bit. Thanks for the info.

Update on my 2021: After a 700 mile road trip (odometer now 1800mi) that included off roading on hard, rocky terrain, my shudder has suddenly reduced by about 50% on its own. If it stays like this I'm not even gonna bother taking it to the dealer like I was planning on doing.

Sandbag solution was short lived. Temps hit the low 80's and it seems the warmer it is the shudder is more pronounced. Sick of this crap.

I have to wonder if a class action suit is the answer.

In my opinion they take a few years to see any results and don't always get the problem fixed. Sometime they only provide limited compensation for any out of pocket expenses towards repairs.

I was notified of the results of a class action suit regarding a 2010 Audi A4 that had an excessive oil burning issue about two years after I got rid of it. The mandate forced Audi to replace pistons and rings on affected engines. They dodged the issue for on 2009 and 2010 2.0 turbo engines for quite a while.

I am tired of it as well. Mine shutters about 99% of the time. I have had the TSB done twice with little improvement. My shudder severity varies all the time. As the amount of fuel on board changes, so does the shudder. When it is cold outside, the shudder is sometimes worse. In other words, it varies all over the place depending on conditions. The TSB cannot be the fix. I am not a mechanical engineer, but it seems as the load changes, so does the driveshaft angle. So, what good is it to make the angle something specific and then have varying load conditions that change that angle?

I was also getting the dreaded clunk when stopping and starting recently, I don't use auto stop. The hotter the worse it got. Saw another thread regarding driveshaft slip joint lubrication. Didn't feel like dealing with the dealership bullshit so I did it myself. That is all good now but the shudder still remains.

I wonder what the difference is from the trucks that don't have the shudder. I have driven three 2020 Rangers including mine and they all have the shudder to some degree.

I also have felt a "clunk" when stopping and starting here lately. I thought it was just a fluke, but maybe I should investigate it a little more.

Look into driveshaft slip yoke or slip joint lubrication. There are ton of YouTube videos for the F-150 on it.

Has anyone disconnected or removed the rear driveshafts and gone for a drive to see if this eliminates the shudder and vibrations ? How tight are the ujoints - is there any binding or notchy feeling to them ? I have seen tight ujoints cause all kinds of steering problems in front axles and create a shimmy from just having one tight cup.

 

[P. A. Schilke]

Hi Folks,

I was wondering if maybe the Tremor driveshaft with the Rear CV joint might work for those cases where the shimming was ineffective. I think the rear axle companion flange is the same, but it is a guess on my part. Further research is needed to see if the Tremor and non Tremor driveshafts would swap out... Just a thought....
