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

[Silverfox]

My 2019 has a stainless shim, but not a half inch shim. More like a 16th of an inch.

So I must have seen that on another truck I test drove. I just checked mine and on the Drivers side I have two shims one around 1/4 inch and the other even thicker. On the passenger side there is only one.

I could be wrong, but I think those shims are to correct the driver's side lean. There was a thread on that but I can't find it.

Finally got a chance to check mine on Sunday. Drove the truck around for about 30-45 min, non-contact temp reading on the pan showed 198f and the dipstick fluid level was at the middle of the diamond, under the 5 mark. Guestimation has that at least 3/4 to 1 qt. low on fluid. There's no sign of leaks anywhere, so it'll be going in to the dealer to have them check it and add fluid so there's a paper trail on it. That way if there are any issues with the transmission later on, I have proof that the transmission was underfilled at the factory.

any luck with the fluid being the possible fix to this?

I have a 2019 2wd XLT with just a 2.5 level spacer in the front. I get the shudder feeling/sound during hard acceleration while turning. I tend to drive it like there’s no tomorrow, but once I felt/heard the shudder for the first time it freaked me out so much I pulled over. Made such an awful noise I thought I broke the tranny. Not something the dealership will be able to replicate unless they’re going to go hotdogging in it. ?

but other than pushing it or having the truck “under load” I don’t have a shudder. Just makes me wonder if it’s going to shit out on me just after warranty. Whether it’s from the fluid or Driveshaft angles it doesn’t feel good knowing it’s more than likely not just hurting those specific pieces of the vehicle alone.

I think I mentioned this in here earlier but my son is a tech with GM and the dealer he works for is also a Dodge/Ram dealer. Some of the Ram trucks have a shutter issue and they drain and purge the transmission fluid and it fixes the problem. That is the official Ram fix for it. Not sure if its the same thing we experience or not.

Had the TSB done today. Better but not gone.

This thread scares me.
I was going to vote: No shudder, but I bet I get it right after voting.
Man, I hope I didn't jinx myself just writing this........

Same as me regarding the slight improvement.

Do you experience any high speed vibration?

No high speed vibration except road surface stuff.

I am planning to buy a Ranger later this year. This thread is concerning.

For those with the shudder, was it there from day one? IE. If I test drive the truck well before purchase, will I know if the shudder is present in that vehicle? Otherwise, is this something that is developing over time?

Thanks for the thoughts.

Mine has been since I got it. I would think if you don't have it you probably won't.

you sure any of the safety features, like traction control etc weren't making themselves known to be active??

yea. I turn the start/stop and traction control off when I hop in every time. I like to push it and feel it. I laugh when crash collision warning comes on ?? I only run with the proximity thang on.

Ford don’t need to know lmfao

I think most of these that exhibit the problem have it from day one. The issue is unless you are on a fairly smooth road and are looking for it, you are likely to miss it initially (especially in a test drive scenario). In my case it was after I drove it for a while I detected the vibration. At that point you become aware of the exact speed and conditions (brisk acceleration will make it more noticeable) in which it is prevalent so it becomes noticeable all the time.

I’ve been following this thread since the beginning and now that I have my Ranger I wonder if we all have different issues. Some people seem to have it at varying speeds while others have it when they get on it hard. Also the magnitude of the vibration varies. I feel it only from a stop at low rpms and it’s pretty subtle. I doubt any passengers would even notice if I didn’t point it out. I’m wondering if those with the more severe cases are driveline related and my issue is normal engine vibration caused by lean mixture tuning by Ford. In which case is normal and most people can’t even detect it.

Same here. I have allot of stop and go on my drive to/from work and plenty if time to notice it.

I went out and crawled under my truck and they definitely installed the tapered shims as the TSB describes. This shudder is definitely less than it was before the TSB work today. I may try shimming the center bearing this weekend to see if it has any effect, it's easily reversible if it does nothing. A few on the forum have had success with it.

I brought my truck back to service on Monday because mine also has a high speed vibration at 80 mph which is driving me crazy (the speed limit here in Utah on the 15 just south of Salt lake City is 80). I can handle a little bit of slow speed shutter (until they figure out a positive resolution) but the highway speed stuff is a no-go.
They are currently working with Ford tech to decide how to address the high speed vibe. The dealer wants to send it out to have the driveline balanced but they need Ford to approve it.
