And be sure to use a quality synthetic or semi-synthetic CV joint specific
grease.  In my 42 years of servicing Lobro CV joints Valvoline DuraBlend
CV joint grease is the best I have found.  CV joints I previously
discarded because of wear that occurred with conventional CV grease have
been repacked with Valvoline DuraBlend and are still running today.

Note that CV joint grease is always enhanced with molybdenum disulfide.

I have no connection with Valvoline.  This is just my personal
recommendation.
