Ram shakes at all speeds

[dmcmd]

Hi all,

I hope someone on here has had this same problem as me and can help me out. I have a 2022 Limited 1500 that I bought new 7/22. For the first 4000 miles it was perfect. Then it started having the problem where it shakes at all speeds, slow or fast. It’s not teeth rattling, but it’s definitely noticeable. If I drive down my street (which is smoothly paved) it feels like I’m driving on a dirt road even as slow as 5mph. I took it to a tire shop and had the tires rotated and balanced, and that did not help at all. Then I took it to a dealership in town (Houston) and they checked the suspension and told me it was working normally. Then I took it to the dealership I bought it from a few hours away and they told me they think I’m feeling the MDS kicking in, and the truck is normal. The problem I'm having, though, is that it didn't used to drive like this. It used to be smooth as silk, and now it's not, so I don't think it's normal. Also, I took a friend out in it and he agreed there's something wrong. I put it up on jack stands at all 4 corners today and ran it in both 4wd and 2wd and I couldn’t get it to shake when it’s not on the ground. I pulled the fuse for the ABS and traction control and drove it around and it still shakes at low speed. Anyone have any ideas? And anyone know how would I get in contact with the regional service manager to discuss this?

Thanks,
Darren

Have the tires road force balanced. There is a chance you have a slipped belt in a tire that a normal balancing machine won't pick up.

Take it to the dealer.

Outboard the frame rails there are some active dampers, used to cancel out vibration caused by cylinder de-activation switching to 4-cylinder mode (ECO).
Try this:
When you put it in Drive, activate manual transmission shifting mode and set the upper number to 8.
Now you have disabled cylinder de-activation, what they are calling MDS.
Drive it around and see if the symptoms disappear. If so, now you know it's probably the mass dampers or their activation circuitry.

Mark the tires and rims too. A lot of places get way to liberal with the mouning lube and the tires walk on the rim and undo the balancing, particularly if you brake hard/late especially right after mounting.

But it's so new, defineitely take to dealer and demand a road test with a tech to show your exact concern so it's not a we couldn't duplicate crapshoot.

what truck do you have?
meaning what package
what engine
etc

They were not road force balanced. I took them to Discount Tire and had them balance and rotate them. I would imagine they didn't do anything special. I would have no problem buying a better set of tires for this truck if I knew that was the problem. It currently has Bridgestone Dueler H/L Alenza 275/55R20 on it.

Take it to the dealer.

I've done that twice now. I guess I'm in for a third time...

My truck has passive dampers on it rather than active dampers. I guess there was a shortage of the active ones when it was built. I have switched it to manual mode and driven it and it does the same thing. And, since the dampers are passive, this should have been happening since day 1 if it were an MDS issue. The shaking started at a little over 4000 miles.

I did that after I had them balanced by Discount Tire. They haven't moved at all. I'm going to have to take it to another dealer and see what they say.

Only other thing I could think of to ask them to check is the runout on the tires, make sure they are round and that none of them are dented or malformed. Both the tires and the rims. Radius and lateral runout.

Thank you for that. I may see if I can swap the wheels out to see if that changes the shaking. If it does, I'll buy some aftermarket wheels. I'd hate to spend a few grand on wheels and then have it not fix the issue.

 

[dmcmd]

Thank you all for your thoughtful replies. I appreciate your help.

The CEL came on last night, so it looks like it's going back to another dealer.

It seems like this problem on my truck comes and goes somewhat. There are times that I'm driving it and there's obviously a major problem, and at other times it seems ok. Yesterday, I went over a set of train tracks that are in bad shape, and afterwards the truck seemed normal for a while. I wonder if there's something in the suspension that could be sticking? I'm going to test it like this a few times to make sure it's not coincidence...

Thanks again,
Darren

Are you driving in 2wd, 4 auto or 4 high? Does it shift smoothly and quickly between them? Any difference in the modes? Don't use 4hi for road driving, but ok to test it for a few minutes.

You could look at the driveshaft and see if you've picked up some crap, but it would've beaten you to death by now.

There's been a few people who got empty transfer cases and rear end cases with no or very little fluid from factory.

Only other thing I can thing of that might feel weird is if the spare tire is loose and is wobbling around back there. Drop it and raise it back into place securely.

I spend the majority of my driving in 2wd. If it's raining or wet, I switch to 4 auto. I haven't used 4 high or low except for testing. No difference in any of the modes.

I've checked both front and rear driveshafts. They look ok. That's actually why I put it up on jack stands and ran it. I figured if it was something rotating that was out of balance I'd feel it. Since there was no shaking, I'm more inclined to think the problem is suspension related rather than rotating body related. But an out of round wheel that's balanced could cause the problem, as you mentioned before.

I haven't checked the fluid level in the cases or the spare yet. I can certainly do those things, although I hate to take the plugs out of the cases. I guess it's not a big deal to do. So far, I've managed to not get dirty

Thank you for your help!

I've read that entire thread. The problem that I am imagining is happening there is a shake at certain speeds which is due to a harmonic of some vibration that they haven't figure out the cause of yet. I had that with an Oldsmobile 98 I had about 25 years ago. I got it to 65mph and it would shake like I was driving over rumble strips. But it would go away at about 70. So I drove it 70.

My current problem is at all speeds. I'll drive down my street at 10mph and it feels like I'm on a dirt road. I can be on the highway and it doesn't really get worse, it's just there.

I guess it could be RPM related. I need to spend some more time testing that.

Thanks,
Darren

If you could find a way to safely lift the truck with all 4 wheels off the ground you could run it at speed and see if it still occurs. But that's really dangerous and I doubt any shop would do it for you. I wouldn't trust just jacking up the truck on stands either. If you only did the rear wheels, I'm pretty sure traction control or ABS would freak.

Maybe find a dyno shop that is setup for AWD so the rollers move all 4 wheels.

This sounds very familiar to my 19 ram, except I knew mine had a issue from day one as I bought it out of state and had to drive home over 1000 miles. So I was tired but I told my buddy around the end of our 13+?hour trip that something didn’t feel right with the truck, felt slight vibrations/ wobbling like through the whole truck and he said he thought he could feel it even in the pass seat! After driving around town for a few months as it was winter time, I didn’t think much about it. As soon as I drove on the highway I noticed it right away again! So I went to the dealer 1700 miles. Dealer told me they have never seen a new truck so out of balance, out by 2 oz. + all 4 tires, the truck had never been off road, driven hard, hit curbs etc… from there the nightmare began multiple trips to dealer with same issues, many new parts. Lied to about many different things, no loaners. Talked down to by dealers and people at ram cares, I realized real quick that no one cared. Long story short I jumped through their hoops, it was long a draining. Dealers were trying to tell me it was mds, I’ve driven mds vehicles for 12 years, that’s not it! Finally after 3 dealers, 1 independent tire shop, I got no where. The wheels and we’re off that truck 25 times in a year with only 8000 miles, tires balanced 7 times, one dealer even tried saying that was normal Finally ram sent a specialist out to the dealer, after three days many new parts, I could still feel the vibration. I told the dealer that day this is enough, it’s not fixed and you will be hearing from a lawyer Now I finally got their attention!!! Ram said to give them a week, at the end of the week they called and said they will buy it back with a 100% refund and they did. To this day I still believe it was the wheels, not the tires! But dealer said they swapped the wheels and tires with no fix! I still believe no one had or has a clue as to what caused my issues. The specialist from ram did admit that there was something wrong, just didn’t know what? This was after ram cares and dealers told me there was nothing wrong, it’s drives as it should just drive it. Tires would not hold balance over a few hundred miles! GOOD LUCK
