Shimmed 3mm then huh? wow that is like NOT MUCH LOL. Probaly found the mount was lose or something, your engine could have turned upside down right in the engine bay or fallen out right on the road. Good thing you caught this man. Great info on this forum big time saver resource if you an issue and you get the standard oh that is normal for this truck from your dealership.

Just dropped my truck at the dealer. There is a bulletin on this vibration issue. I saw some of the paperwork and it said something about re-centering the engine/transmission on the mounts and shim the motor 3mm.

 

So they're gonna work on it. I'll report back after.

Does your truck have the rough idle when it's been running for a while? My truck does it after it's been running for a while and I come to a stop. Also it does it when there is incline. Did your dealer pull up the bulletin? Thanks

 

Planning on taking it tomorrow morning.

Yes. The bulletin says it's caused by the motor and transmission not being centered on the mounts correctly. This causing resonance aka vibrations. They need to measure to recenter and then use shims to space the motor mounts 3mm.

 

It's not really that the engine is idling rough. But mine had a vibration when in P, R, N, D. Was more prevalent after the truck was at operating temperature.

 

I forgot to write down the bulletin number. But just take it in to the dealer and ask them to look it up. Luckily, my dealer is very helpful and responsive

Thanks. At the dealer now said they will take a look at it. Hope they don't give me a hassle. Did you get your truck back the same day?

No. I just dropped it yesterday at 2:00. After about an hour my service writer came and said he wants to give me a loaner. I hope to get the truck back today.

fondupot,

 

Service guy asked me if i was going to wait for it.... that it might be a 3 to 4 hour job. Asked the service guy if he can pull up the bulletin but said only the techs can. So we shall see.

yea hopefully I hear back from them today.

Service guy just came in and told me they found the bulletin and have started working on it. Said it will take a little while... so i believe you will get yours today. I'm waiting here on mines so shouldn't take more than 3 or 4 hours i believe.

Got the truck back already just under 2 1/2 hours. Got home sat there for a few minutes on the incline and idle wasnt rough. And seems to have fixed the issue. Wont know until later today for sure when i drive it for a while.

Did they find anything wrong and what corrective action was taken?

Just went to the dealer and told them that after my truck has been running for a while or reaches normal operating temperature, it idles rough.... i showed them what fondupot posted about the bulletin of the shimming the engine 3mm and they looked up the bulletin. They went ahead and fixed the right side of it engine mounts by shimming 3mm between the engine and the plate??? Ill check when i get home. But ive been driving for awhile now and it seems to have fixed the issue

Got my truck back too.

 

Honestly, feels the exact same when sitting at idle. The motor isn't idling rough, they checked for stored misfire codes, so I guess everything is fine.

 

But they did the bulletin re-centering the trans and motor mounts and shimming the motor mount. Feels exactly the same though.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By KARNUT · Posted

      Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Chuck FB · Posted

      Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL.

      Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
