- Highway vibrations since i bought the car( just about to solve waiting final touch)
- Some knocking on low speed gear down or up. especially on traffic car is knocking me


No further issue.
I wonder if these mystery vibrations can possibly come from the driveshaft, guibo. If they can't find/fix the vibration for you, have them look at that assembly. If the driveshaft wasn't properly balanced it will cause a vibration. The faster you go, the more it vibrates. If mine did that, I would Detach the driveshaft from the rear and rotate it 180° and re-bolt it on.
