Stay away from bearings made in China.

Mobil makes a good quality synthetic grease made for bearings and sold in grease gun cartridges, popularly available in most auto supply houses. All old grease must be removed before regreasing the wheel bearings.

Search the archives using the keywords "bearing preload" and you'll get a lot of information that you need on this subject.
