I took my car (1995 Honda Civic) to a mechanic to fix the front passenger side wheel bearing. After replacing the wheel bearing, the loud noise in the car continued. He did inform me that the old wheel bearing that was taken out was damaged, and was correct about it needing to be replaced. He further inspected the car and concluded that it was the transmission bearing on the same side. So I have some questions; Is there a such thing as a transmission bearing? Would a damaged transmission bearing cause damage to the wheel bearing as well? Also, my front two tires are bald, could this be causing the noise? And would it be efficient to switch the front two tires with the two rear?
The wheel bearing has nothing to do with the transmission. When you need a wheel bearing, it is because you abused the steering system to the point of damaging it, hard turning, pot-holes, curb riding. Transmission has a throw out bearing, a rear main seal.
