    Thanks. I found my answer. The 4x4 actuator on this particular vehicle is located inside the transfer case, hence the $555.00. Apparently I was following the (my) wrong direction ordering this part.
    Appreciate all the videos you put out!

    @Redlinesixtynine You're welcome. Thank you for checking out our auto repair videos. At the current time we do not have a video on that particular repair.

    You may want to inspece the front differential and also the front axles, to see if anything needs to be replaced.

  • @1AAuto
    @1AAuto  Před 11 lety

    You would want to check for leaks as well as test all of the actuators out to see if they are functioning correctly with 12 volts.

  • @1AAuto
    @1AAuto  Před 11 lety

    It may be the actuator. You may also want to check any electrical connections or vacuum lines associated with the system.

  • @timeless6964

    Good to See, it is Not a vacuum unit!!!

    You may want to join a message board for your vehicle to see if anyone else with your particular year vehicle has ran into the same issue, and what they did to resolve it.

  • @1AAuto
    @1AAuto  Před 11 lety

    This video shows you how to replace the actuator. Was it a different year that you were looking for?

  • @Redlinesixtynine
    @Redlinesixtynine Před 12 lety

    Again. I appreciate these Envoy vids as they are a great help to those of us repairing them.
    What about that heavy bearing on the side of the oil pan, that the front axle runs through. (it sits beside this actuator). Do you have a video of that repair/replacement ?
    Thanks.

  • @1AAuto
    @1AAuto  Před 12 lety

    The scanner would have to be a Tech2 bases scanner which normally runs on the cheap end for $1000 and the top end which is $10k. Most likely you will have a hard time finding someone with the correct scanner outside of the dealership.

    Thank you for taking the time to make these videos. I used your brake tutorials and they made the job super easy. My question is do you have a CV axle DIY video? When I did the front driver side brake there was CV grease spattered all over the frame. I didn't check the condition of the boot because I didn't want to risk getting the grease near the brake components so I don't know if I need to repack it, or replace it. Thanks again!

  • @1AAuto
    @1AAuto  Před 12 lety

    You may want to check the power going to the blower motor to see if it's working.

  • @1AAuto
    @1AAuto  Před 12 lety

    The issue could be the actuator but your best bet would be to bring it to someone that can read the 4WD trouble code that keeps appearing.

    We currently do not have a video specific to the axle. Here's a front hub video though, that will give you a good idea on how to get to it. Hope this helps you out. czcams.com/video/yZ13Qet234c/video.html&feature=plcp

    If you follow the video you shouldn't have any issues with making the repair yourself.

    I recently started to hear minimum grinding noises coming from the right side of the vehicle. I was told that the actuator "could" be trying to lock-in during a bumpy road. I went ahead and disable the actuator from the power source to determine if the sound would come back. Opinion, is this ONE way of disabling it and will it function properly? ( I realized that once disable. I would no long have the 4WD function)

  • @Elnenezx12r02
    @Elnenezx12r02 Před 4 lety +1

    Is there any indicator on the dash or a check engine light code that will come on to let me know the axle actuator is bad?
    My trailblazer doesn't feel like the 4wd is kicking on and she fish tales alot just taking off.
    I need help

    hey man i have a question i have an 03 trailblazer i replaced the actuator (thx by the way i learned by watching this video) anyways when i put it in a4wd hi or low you can hear the actuator working but the front wheels dont spin and every once in awhile you'll hear a clunk sound when i engage the 4wd any ideas on what it can be ??? thx in advance ...

  • @smokedawgracing

    Hello
    My actuator has fluid coming out, does that mean i have to change the housing also?
    Thanks

  • @heretohear8662
    @heretohear8662 Před 12 lety

    Dealer told me I needed the front fork actuator and when I went to look it doesn't exist. I can see that what is there looks as though it is a universal part that was machined for a fork actuator, but just nothing there... any ideas??? It is a 4.2 Buick Ranier CXL AWD

  • @djkaanco
    @djkaanco Před 11 lety

    any idea why oil would be leaking from where the actuator goes into the disconnect? is there a gasket there or is it just a worn actuator? and what kind of oil is in the disconnect? transmission or motor? it seems i have to change the gasket for the disconnect as well as there is a small leak there as well.

    • @nickhutchins4239
      @nickhutchins4239 Před 7 lety

      I don't know if it's a transfer case control module problem or actuator problem, maybe something else?

    My 2004 Trailblazer won't come out of 4LO, would this be the front actuator?? It won't shift into any other mode 4AWD, 4HI, or 2HI.

    • @1AAuto
      @1AAuto  Před 6 lety

      +Dalton Baumann It may be due to a bad 4WD actuator. You may want to see if it is working properly. 1aauto.com

    @welchtommy Před 10 lety

    I replaced my actuator and when i did i added some grease to the hole it goes in
    could to much grease be causing the actuator not to return to 2wd?

      It may if enough of it got into the hole.
