Lawrie and everyone else who responded - thanks! Now one last question:
When re-torquing, what is the preferred method. In the past I have gone
from bolt to bolt (in appropriate order), and slightly loosen the nut, then
re-torque to 50 ft. lbs. Is this correct? Is it recommended to loosen then
torque?
Regards,
Chris
