Just saw this on http://www.machinerylubrication.com/...e-right-grease
Greases containing moly are recommended for roller bearings subjected to very heavy loads and shock loading, especially in slow or oscillating motion such as found in universal joints and CV joints. If such greases are used in high-speed bearings, problems can be experienced with roller “skidding” where the bearing roller fails to rotate through the full 360 degrees due to reduced friction. As a result, the roller develops flat spots, and its service life is reduced.
some truth to what you say
yet the high speed you speak of resulting in ' skidding ' happens
with HI output / HI rpm engines & drive trains
actually directly related to ' loading '
observed far above what you could Ever achieve with an FJR
' lithium soap grease ' doesnt fare nearly as well
as other type o grease on 200 HP + / 200 mph + bikes
there again NOT an FJR !!
some grease actually Fail under those circumstances from Heat !!
thus the advent of ' Ceramic Bearings '
sometimes the splines in actually get slightly twisted from
torque or abuse resulting in binding .................
seldom happens from normal operation
splines straight = good
splines slightly twisted = NOT Good noticeable on
disassembly ................. seldom needs repair
[ parts need to be replaced ]
not drag racing or doing rolling burn outs = NO worries!
with bmw's steel parts would rust & bind severely affecting
rear suspension travel otherwise few ever notice
