Why Truck shaking & vibrating and excessive noise under truck, diagnose truck vibration while driving, bad ujoints on truck cause shaking and vibration in truck.
No caps over spring brake cage hole will allow dirt and salt to get in, and can cause brake failure. Little things like this and not greasing can cause big failures.

I notice strange lines like scratch marks on my rear drive axle super single tires. More lines on driver side tire. The front drive axle tires are perfectly fine. Just wondering whether this could be a differential axle issue? Any thoughts? Suggestions?

I was having the same problem. I watched a video leveling the drive shaft by regulating the leveling valve. In the Freightliner Cascadia there has to be a different of 2 inches 3/8 between the mounted in the chasis and the leaf spring. Mine used to have almost 4 inches and it started vibrating at 60 miles per hour up to 75 m/h. Great help from the presenter, if the vibration is in the steering wheel, it may be the bad alignment in the front tires. If the vibration is in the passenger seat, it is the drive shaft that is not aligned. The airbags are too high.
