Two technicians are discussing wheel bearings. Technician A says that conventional tapered roller bearings as used on the front of most rear-wheel-drive vehicles should be slightly loose when adjusted properly. Technician B says that the spindle nut should not be tightened more than finger tight as the final step. Which technician is correct?

Question

Both technicians are correct. Tapered roller bearings should have a slight amount of play when properly adjusted to allow for expansion as they heat up. The spindle nut should be tightened finger tight as the final step to ensure the correct amount of play.
