Rumble strip noise?

Coming from the front right, I occasionally hear what feels and sounds like I'm going over a rumble strip along the edge or middle of a two-lane. It's at various speeds, and seems more likely to happen on slight curves. I'm thinking wheel bearing, but would welcome any other ideas. Thanks in advance for your thoughts!

That is most likely torque converter lockup starting to slip or fail during engagement.

It could also be a sign it is time to replace your transmission fluid especially if it is the older fluid before they made the change to the newer fluid.  The older fluid if I recall seems to absorb water and would cause the same symptoms. My 2018 I bought as a certified pre-owned had the older fluid. The dealer had never run it up to the transmissions operating temp and didn’t know it was having the problem. After I made them aware and raised a stink about it they had it flushed and the fluid replaced with the new fluid pretty quickly.  The problem went away. That was 2 years ago.

It is definitely worth a fluid change.  Caught early enough you can save it.  Just don't keep driving it that way.  If it comes back soon you can try an additive (Lube Guard 63010) to buy some more time.

That new fluid for the 8 speed transmission only. 6 speed takes the Dexron 6 fluid.

If the rumble is from the converter, I'm pretty sure it's too late for a fluid change to help. How many Miles on transmission

One year old transmission rebuild, stem to stern. I've had it back to that shop, who have a good reputation, and they deemed it fine. To me, the rumbling does not appear to be shift related.

 

It's frustrating because the noise only exhibits itself occasionally, and of course never with the mechanic in the truck! My guy is looking at the wheel bearings today, so maybe I will know more after that.

 

Thanks again!

My guy ruled out wheel bearings...goes to show what I know!

 

He "re-learned" the transfer case and front axle lock up, and we're both hoping that solves the issue.

I've only driven it twice since, without no noise recurring, so my fingers are crossed.

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
