Failed bearings are usually caused by improper install, lubrication or poor pre-load... all fall under the heading of user error...OK.. Its happened again... The Front Wheel bearing is stuffed again..
It seems every 12-16 months I am replacing wheel bearings..
I have never had to replace the wheel bearings so often on any other vehicle before !
Its getting a tad annoying.... 3 sets in less than 4 years !
