Lonestar Vibration

In terms of the driveshaft, back in late 2023, I took it to my local drive line shop and they did the following repair: Front shaft: replaced midship yoke, stub, steady bearing, nut, and washer due to being worn out, mid ship yoke seized on stub. & Rear Shaft: Replace 1 - u-joint, slip and spline due to excessive play in slip and spline.

The truck vibrates, regardless of whether I am pulling my b-trains or bobtail.

I also couple of weeks ago took my truck to another local mechanic who does drive line work and he checked the main(long driveshaft) and said that there is play and that it needs grease. I did not take it back to him yet, because I was experiencing vibrations last time as well when I had fresh driveshaft work done.
