Cadillac Repair: Replacing 95 Deville Front Wheel Bearing, sway bar bushings, wheel alignment

Question
How difficult is it to replace the front hub/wheel bearing assembly? I'm killing 2 birds with one stone. Abs speed sensor and bearing at same time. Is it 4 bolts plus axle nut, and reverse to install? Will it need a wheel alignment?

Secondly, previously replaced one bad sway bar (Z shape) link and now sounds like rapid fire over some road conditions. Right side link looks good. Would you suspect sway bar bushings since the link went bad originally?

Thanks, Ed

Answer
The hub and bearing is actually very easy, you will however need a very good air gun, i doubt you can crack the center nut yourself. I needed a 350 ft lb snap on gun to crack it. Check the bushings if you suspect it, i would say yes it sounds like a bushing, or simply a bolt it loose.
