Abstract
A delashing assembly includes a tightening device for tightening a nut in relation to a main shaft supported on bearings and a wireless interface, wherein torque information is received by the tightening device over the wireless interface. A main shaft and main nut assembly, as well as a steering system, may include the delashing assembly. A method of delashing the main shaft and main nut assembly includes providing a tightening device on a first end of the main shaft and sending torque information from a second end of the main shaft to the tightening device over the wireless interface.
