Hey guys i have a pretty bad vibration when i hit the 60-65mph mark (bobtail only haven’t tried a load yet) if i go above/below that is not as bad. Just change my rear tires, breaks and all 4 seals. I also have new breaks in front. Freightliner Cascadia.
Get under it and shake them and if has the non grease able U joints shake them harder and look carefully at them there shouldn't be grease getting out of them as they are sealed for life?
