[V8] Bad Front Wheel Bearings(non Audi)

[toml99 at todomundo.com]

It's not an Audi, but my 2004 Chevy 2500HD Duramax started a shimmy  
on the highway....went away with braking....took it in today to have  
the tires rotated(and while it's up) shake the front wheels.......one  
had 1/8" slop...other was about 1".....68K totally stock....bearings  
are "sealed spindle unit" and are about $450 each from the dealer/ 
others....I've got a set coming(timken original).....for $180/each   
free shipping........Common problem apparently....Aren't you glad you  
don't own a vehicle "built like a rock"......Tom
