Put my Trailblazer up in the air again, went to use my 4x4 last night in the snow and no joy. Determined that the transfer case is working as I got it into 4-low with no trouble. So I bought a front axle actuator. Went to install it to find that the actual bearing housing is fractured and the half shaft is laying down from the axle itself. I have no idea why this happened, she runs on the highway and city streets exclusively and No four wheeling shenanigans. Went to buy the part and nobody has it locally and had to order it, not to mention $6-700 pricing depending where you order it from. So I bit the bullet and ordered it with RockAuto.com for $355 and tax plus 17.99 expedited shipping to have it this Wednesday. All told $396. Looks to be pretty easy to replace, just have to bust the ball joints apart and then get to the housing, I’ll replace the actuator motor while I’m there since I already bought it. 170k and it’s starting to nickel and dime me, but I’m hoping to hang onto it for another year and pay down a bit of debt before I upgrade to the new Canyon / Colorado quad cab. Will get it fixed up this week.
