Hi Everyone, I'am new member here and would like to know if when replacing the wheel bearings does the hubs needs to be replaced also. Is it also recommended that the left and right side be done at the same time? I took my 1996 legecy outback wagon to Big O tire store and they said the hub part is a dealer item and the bearing can be aftermarket. They quated me around 350.00 to do one side. Also my car has 125,000 miles the struts show some signs of rust but do not appear to be leaking. The car seems to ride fine, would I be wasting my money replacing these struts now instead of waiting for something to happen? Thanks:)
