Not another Ranger Slip-Bump thread when stopping....Advice needed

[omega26]

Hey everyone, new member here.

So I recently purchased a 2023 Ranger XLT Tremor, and while on a road trip at about 2000 miles on the truck it began experiencing the characteristic bump from the rear of the vehicle after coming to a complete stop. The harsher the stop, the worse it felt. When accelerating from a stop, it felt less apparent but still present. I experience no noticeable vibrations or shudders while traveling at speed.

What seems different in this case is that after taking it to a dealership and having them grease the slip-yoke, it seemed to do nothing at all. It was still present and didn't feel reduced at all. And the bump is present every single time unless I come to a very gradual stop.

I am now at about 6000 miles and have taken it to another, much larger dealership. After looking at it they ordered a new driveshaft (backorder, no ETA of course), and when I asked for the fault they found they stated there is "excessive play in the carrier bearing." If this is truly the issue, would greasing the slip-yoke at least have some effect on the problem?

I guess my question is, are there alternative causes to the bump when stopping problem experienced with Rangers? Just seems really weird to me that greasing the slip-yoke splines wouldn't at least reduce the issue, and if that didn't affect it at all I am skeptical that a new driveshaft will fix it.

I am wondering if there's something else going on, like the rear suspension extending during braking as there is forward body pitch and that its sticking or otherwise creating a bump. The bump for me seems to happen right after the vehicle returns to level just after the forward pitch from braking.

I have had similar observations that the more aggressive the stop the worse the thump. Could be the amount of extention of the rear suspension. I have had one other thought. Does the Torque converter lock in first gear? If so, when does it release on stopping? If it releases to slow the drive line would stay loaded too long and when it released it would cause the thump. Just a though, may be wY off.

Mine DOES NOT DO IT in sport mode , just in D or Tow , clunky downshift most likely ...

The carrier bearing is a softie
If too soft you're drive shaft will go out of alignment and give you all sorts of things to complain about through various modes of twirling.
It would be nice if an aftermarket bearing could be installed that's stiffer, and we could see if its a positive change or not. Some people elect to completely remove it with a solid driveshaft.
I think mentally my brain has compensated for it and I manipulate my breaking pressure to mask it happening.

 

[omega26]

Mine seemed to do it in Sport mode and when manually cycling gears to keep it in 1st and then brake. Checked this to see if it was just harsh downshifts.

Thanks for the feedback @Wang.S, do you happen to know if the ranger driveshaft assembly includes a new carrier bearing or is that a separate part number? I emphasized to the dealer that the Tremor has a different driveshaft so hoping they order the correct one.

My driveshaft seemed to be able to move laterally what felt like almost 1 inch each direction pretty easily in the carrier bearing but I have no comparison for what's normal.

I've stated in another thread about the driveshaft, that Ford has one on order for me in backorder status also. My issue is rattling/tapping noise when accelerating mostly. It just seemed to start all at once at around 10K miles. The previous owner had it for about 6K miles but pulled a heavy trailer with it through the mountains of West Virginia. I'm thinking he traded it in needing more towing ability. He had added a trailer break to the vehicle which I'm grateful for. It's possible his actions helped expose this weakness, but then again, I'm just thinking out loud.

I have a 2022 4 door thats doing this. Its done it for a while and i always assumed it was the transmission. Its really noticible sometimes, sounds like i have something in the bed that is flying forward and hitting the front of the box. Its a very pronounced thump though and it does not always happen while stopping, sometimes it will make the thump after its almost settled. I still feel like its the transmission trying to shift. Once or twice its almost felt like someone bumped me from behind. I would like an actual solution though, and not have to replace parts just to have it continue.

I want to add my truck has 11,300 miles roughly on it and its been doing it for the last 5k/ 6k miles

is this just a Tremore issue, for the most part its Tremore owners I have heard this from? I believe your drive shaft is different in the Tremore ....
I have a 21 XLT Sport FX4 I have less than 20k I drive and tow "a lot" I use Sport mode while city driving, it has been nothing but a smooth ride?

You have made a great point of possible cause that I never thought of, Rear End extension.
For my 22, it’s only been noted a few times - Feeling of something hitting front end of the bed.
And yes the thump is more at the very end of forward momentum.
Since I have not had this issue on a continuous basis, never really put a lot of thought into it and have just figured to do the slip yoke lube if ever it became annoying.
I will say I have not towed yet, but occasionally have a small load in the bed.
The truck drives way better with a load, more planted. I did swap out my rear shocks for the 4600s, got rid of the annoying bounce.
I guess take it out to an open parking lot and play with different braking ways both with and without a load- being attentive to the rear drop/settle.
As this feeling for me is more felt like someone kicking my seat back.
I would think driveshaft thump would be more felt in your floorboard.

Mine drives and shifts more solid with weight. Even 300-400 pounds in the bed makes a big difference.

try shifting into N before coming to a stop and see if it still has the thud and slaps. might be the harsh down shift like mine has. if it does not do it in neutral it may help diagnose.
worth noting ive been through a few of the center support bearings in 34k miles lol.

Thanks for all the feedback everyone.

I know I have seen a poll on here trying to see if this bump phenomena is more prevalent on Tremors vs. non-Tremors, but I would love to see if Ford collects service data on this. Different suspension and driveshaft on the Tremors.

I have messed around with my truck in manual shift mode enough and this doesn't appear to be a harsh downshift issue, but maybe braking while in neutral would rule out the torque converter release as a cause?

I might also have someone jump up and down on the tail end of my truck while I listen to the suspension to see if that makes any noise. For what its worth, the dealership greased in between the leaf springs in case they were making the noise. Didn't have an affect.
