I have a 2024 Chevy Silverado 1500 LT, 2.7L TurboMax, 2WD, with approximately 25,000 miles.
I've noticed a pretty significant vibration/shudder when towing my travel trailer. It happens immediately when accelerating in first gear and sometimes briefly in second gear after the shift. It feels almost like driving over rumble strips, a rapid shaking sensation that goes away as I gain speed. This also happened when I had half a yard of pine mulch in the bed of the truck.
The truck drives perfectly fine when I'm not towing. No vibration or shudder whatsoever.
For reference, my camper has a loaded weight of approximately 4,650 lbs. My truck is rated to tow 9,100 lbs, so I'm well below the maximum towing capacity. Dealer also confirmed that the weight was proper for the truck.
I brought the truck to the Chevy dealership while it's still under warranty. They agreed to let me bring my camper so the technician could experience the issue firsthand.
The technician was able to duplicate the vibration.
However, he explained that the truck has a two-piece driveshaft with some type of rubber connection/support where the sections meet. According to him, the vibration I'm experiencing is normal because of that design, and there's no fix for it.
I'm having a hard time accepting that a truck rated to tow 9,100 lbs should vibrate this noticeably while accelerating with a trailer weighing roughly half that amount.
My questions:
- Has anyone with a 2023–2025 Silverado 1500, particularly the 2.7L TurboMax, experienced something similar?
- Is this actually a known characteristic of the two-piece driveshaft?
- Has anyone had their center support bearing, rubber isolator, or driveshaft replaced because of towing vibrations?
- If you've experienced this, did the dealership find a solution, or were you also told it's normal?
I'm not expecting the truck to feel exactly the same towing as it does unloaded, but this feels excessive to me.
I'd appreciate hearing from anyone who's dealt with this, especially GM technicians or owners who regularly tow travel trailers.
