Well here we go with part 2. In this video we repair the viscous coupler and get this Kia back on the road for a fraction of the cost of replacing the whole unit!

    The driveshaft buthurtness comes from phasing, not balance, necessarily.
    If a certain "drive line"
    Of components had to be phased and tested and re-phased to find it's optimum feel without fighting itself, it got marked by it's selling dealer, back in the day, ykno, when Richard petty drove a Ford Talladega, the pickups were a good example where the phasing being marked and noted, before servicing its parts, was applicable.
    Without it, the truck would hump and thrust. And that could be bad. You would have to "find the phase"
    Newer ones could be assembled 180° out of phase within the joining of halves of the shaft. I saw a Boeing guy accidentally do this once and give up.
    The wise old man showed me the simplicity of correction perching it on sockets on the floor, first right, then wrong, then right again.
    Savvy?
    Happy motoring.
    With your….engine.
    In your motorcar.

    Just one thing, the new bearing has covers on both sides like those used on a mower-deck spindle.
    On those, they fail fast for lack of lube.
    All the lube they have was there during bearing assembly.
    If you can remove one cover, grease it, then reinstall that cover, it can last longer.
    If it was a mower, you can leave the inner halves of the upper and lower bearing's covers off and facing each other, the bearings can be greased occasionally, by pumping the cavity full where the spindle runs within.
    On the Kia automobile, you could reinstall the bearing cover, then assemble the unit with having packed that bearing, otherwise, it's a matter of time, climate, and miles driven.
    Your automobile doesn't cut grass and get rained on like a mower, so….
    I would have greased it before and put that cover back on over the grease and then driven it into the coil housing.
    Just had to point that out. Front wheel bearings on FWD are sometimes supplied without really being greased right also.
    I bet you get into those and grease them.
    Just like everybody else who does a good and thorough wheel bearing press apart, replace bearing, and back together. With your added grease,
    They last alot longer and it keeps water out.

    That means blessings to you, or so I gather

    Eric there's nothing like the fact that you can stick it to the man at Kia and tell him to keep their $1400 part

    The Factory just wants you to throw whole assembly's at it. Mercedes is the worst.

    So I know instead of replacing you've torn apart the old coupler and repaired it. This coupler seems to be a common weak point on the 2nd gen ('07 – '12) Santa Fes. I currently own a 2011 that I just had to replace the AWD viscous coupler for the 2nd time in under 6 months/21k kms, thankfully it was replaced under warranty because of a rear-end accident that happened April 2021. However, the new coupler only lasted 3 months before it started showing signs of failure again, shimming/bucking/kicking while under acceleration, and randomly while pulling away from a stop sign/light. It's been mentioned to me in a Hyundai owners group that when replaced, the computer that controls the coupler may have to be reset, so that it knows it's working with a new unit, and not an old one with half worn clutch packs. The replacement was done by an independent shop and not the Hyundai dealer, but there was no mention of having to reset anything by way of computer. SMA, do you know if this person is correct? Is there a procedure that needs to be done, likely by dealer level scan tool, to reset something?

    That's crazy. That lady has a one of kind fix only because someone cared enough to not just stick her with a $1500+ bill just because. What do you think the other Kia Sportage owners are thinking if they see this video? wow.

    Thanks for going this extra mile ! I’m sure the customers appreciate it !

    these 2 'viscous coupler' videos are your best videos that i've seen ……it shows how reliance on experience and remembering basic tried and tested techniques plus attention to detail leads to success 9 times out of 10 …..well done

    Poorly designed part.

  23. Avataaar/Circle Created with python_avatars Richard Crouse says:

    I like the design of that seal. The inner surface that goes on the yoke before the main part of the seal goes in the housing acts as a sacrificial piece so it will be damaged instead of the yoke shaft. Great idea.

  24. Hi Eric, great job and very helpful for my own Hyundai Santa Fe, which is doing terrible “cracks” from the rear diff when turning.
    I just removed the rear coupler like in your video.
    When moving the “propeller” (in dismantled state, not connected to power) the coupler is closed and the second side is also rotating.

    Is this the indicator, that’s it’s broken?

    I guess it should be open, when not connected to electrics.

    Thanks for your help!
    Greets from Germany!

    Hi Eric ! I notice you didn’t fill it back with oil .. I’m in the process of putting mine back together and I’m honestly stuck on how the hell to put that 150ml back in there other then tilting the Sportage on its back so the oil stay in the bol .. any tip ?

    Learn a lot watching you dismantle and renovate the “unserviceable” part. You are a tremendous teacher.

    Good to see you working on something you have not done a million times. I liked the view from the "top of Avoca", too. The landscape reminds me of northern Maine.

    good money save on bearing and seal replacement.
