Wheel bearings

["Jon" <jwilliam@ns1.water.net>]

Last inspection I had the mechanic informed me that the *pop* I heard 
coming from the right front tire was a wheel bearing.  He predicted 
that it would get noisier and start to howl after a while.  His 
prediction was dead accurate and so I was wondering how difficult it 
was to change a wheel bearing.  Do I need any special tools?  I 
guess I should change both front or is that unnecessary?  Is this a 
job for a mechanical newbie or should I let a mechanic do it?  The 
Bentley procedure looks deceptively simple but it also includes 
special tools.

TIA
