For many years SVX owners have felt the consequences of not repacking the wheel bearings with grease before they were installed. They were originally sold packed only with only a substance that protected the metal surfaces of the components in the bearing between the time of manufacturing and were sold to the consumer, and installed.
It would make no sense to just install them without making sure they are correctly greased. What "some guy" that answers the phone at "tinkers" said would never be good enough for me. That could even be where that old saying "not worth a tinkers damn" came from!
Considering the history of problems from not flushing the bearing out and installing them the way they are when sold. I for one would take the little effort required and make sure it is correct. Too expensive and time-consuming if it isn't done correctly.
But... that is just me.
