Remove the spindle/knuckle from car.
Take new bearing, new snap ring, and knuckle to shop for press out of old hub and bearing. When looking at the bearing look in the bore and you will see where the inner and outer races meet (groove)... take and slide the races apart (they only move a weeeee bit) and get some real bearing grease and start packing it into the groove to get real grease into the ball/race cavity.
Then press bearing into the knuckle, install ring, then press hub through bearing bore, install back onto vehicle.
Reason is, bearings is supplied from vendor, and nobody "specs" and actual lubricant to be used, so they get installed into the vehicle with some kind of white butter stuff that aint worth what it made of..
Some Kendall 427 Blue or Mobil-1 synthetic grease will do the job... though I have Mobil-1 at home, and shop has Kendall 427.
