Kid, the last Blazer I owned was a 98 TrailBlazer I think. I went to put the bearings in the front, and snapped off a wheel lug or two. Get the wheel off, and find that my 2WD had 4WD hubs, doubling the price. Then I found out, there were 2 years that used special hubs made in Canada, special order from the dealer only, double the doubled price. Won't ever own a Chevy again.
