Stiff steering after front end re-assembly?
 

My vehicle is a 2000 Volvo S70 and recently I just replaced the front wheel bearings. After I re-assembled everything, my steering is pretty stiff. Before replacing the bearings the steering was was not stiff in any way. Is it possible to over-tighten something that would cause stiffness in the steering? If so, what would cause this so I can back off on it a little bit. Thanks in advance for your help.
