• ◆ It is always necessary to measure radial run-out when thrust tube has been removed. Affix a new coloured dot and remove the old colour marking.
• ◆ If a new propshaft is installed and if the marking on the flange shaft of the rear final drive is no longer visible the position of maximum radial run-out must be determined and marked by a coloured dot.
