Thanks. I'll be checking this out tomorrow. The bolts were taken out already. I didn't really get a chance to mess with it. The dude working on it said he couldn't get it apart. I figured I'd ask someone before I messed with it.
I apologize I can't answer your question, but check on www.355Nation.net for a positive answer. Its a site dedicated to Colorados/Canyons and there is a ton of useful information on there about those trucks!
Thanks for the info. I was able to get them off. The truck was originally from Michigan, so there was a little rust build up on the hub and spindle. It just needed a little persuasion to come apart.
