[2kTrailBlazer]

well i dont know if you have the same set up as a 2000 blazer, I own one, i also just replaced both half safts, i actually did the whole differential...but anyways i had to take the whole spindle off. bearing and all. and the hole ur talking about ?? im assuming your talking about the bearing...Im not sure.. you may also have to take your shock out on the right hand side again im not sure if you have the same setup as mine... take some pics maybe easier to help you . you can try to just remove the bearing assembly... again, if its the same as mine, 3 18mm bolts hold it on from the back.. goodluck hope this helps a little.
