Do you grease pack wheel bearings on a 92 Toyota corolla?

I have a 92 toyota corolla and I'm replacing one of the front wheel bearings. My ? is do you pack them or are they pre lubed?Do you grease pack wheel bearings on a 92 Toyota corolla?They are a sealed bearing. You can grease them all you want. Your not going to get it in past the seal.Do you grease pack wheel bearings on a 92 Toyota corolla?there is factory grease on them but that is so they don't rust. Definitely not enough grease as what you need in the wheel. I would put a gob of grease in the palm of one hand and grind the bearing into the grease with the other hand to really get it in there. Also, the race(where it mounts onto) needs to be cleaned of old grease and dirt and new new new. Better to overgrease than undergrease.
