The vacumn hubs may not engaging all the way. Did you also replace them with the bearings? They are designed like interlocking fingers and if they have partial vacumn to them it will cause them to make one of the worst sounds on earth. The vacumn is controlled by a solenoid on the firewall with a dual tube to the back of the hub assembly.
