From what I understand the reason for the increase from 118 to 160 ft/lbs is to actually force the hub further onto the spline. At 118 ft/lbs the hubs were moving in on the spline due to driving/cornering leaving little or no torque on the nuts. The increase forces the hub further onto the spline so that no more movement can take place, allowing the nut to maintain proper torque.
Mine were tightened to 160 ft/lbs several months ago and are holding fine without Loctite. Previous to this, they continued to loosen at the 118 ft/lbs setting.
I'm keeping an eye on it and will add Loctite if they ever loosen again.
