my wifes trailblazer has been making noise on the passenger side and i thought it was the wheel bearing at first but when i checked it it seemed fine. so i took it apart and checked it and it was fine. after spending some time thinking it over and then doing an internet search(how i found the site) i saw some posts about the right side support bearing going bad. went outside grabed the inner cv and it has a good amount of play.i did a search and didn't find much on how hard it was to replace the part as i plan to do this myself. when i called my local chevy dealership they told my that the whole assembly was discountinued but i could buy just the peices to fix it. we'll if anyone can give me some insight i would be thankful.
