    Thanks, I've bookmarked this. I actually bought a new "clicky"
    torque wrench when I did the brakes on the Sonata; figured it
    might be a reason why so many people were having warped rotors.
    since I put new rotors all around, I figured it behooved me to
    make sure they were torqued correctly.

    Of course, the first thing that happened after I did the brakes
    is I took the car in for inspection...and they removed the tires
    (I presume, it says they did) and torqued them to heaven knows what.

    When I get it inspected this time, maybe I will check the
    torque. I didn't have the huevos to *tell* a tire shop what to
    torque my wheels to. Still, you never really know, the "tire pro"
    may be some ape who thinks "all lug nuts must be tightened as
    tight as they will go with the pneumatic wrench".

  3. I take a copy of the torque setting into any mechanic I go to.
    Since I mostly go to the same place, the guy already knows the
    settings. He's the one who replaced my tires and rotates/balances them
    as needed. It's a real PITA to use a torque wrench to set them and I
    still think that should be a recall by Hyundai. The damage that can be
    done is beyond just the rotors. It can also damage the bearing, hub,
    wheel rim and cause vibration and shimmy to the steering wheel. It's a
    serious problem that Hyundai should have addressed to each and every
    vehicle with this problem, IMO.

    You did read the manual, right? So you know how to properly store the
    wrench, right?

    This is good, but if the mechanic doesn't already have access to such
    basic information about your Hyundai, do you really want him working on it?
    Why is it hard to use a torque wrench on your lug nuts? I rotate my own
    tires on my Sonata and torquing the lug nuts on a Sonata is no harder
    than any other car I have owned. What model Hyundai do you have?

    How does improper torque damage the bearing and hub? Yes, it can damage
    the wheel rim over time. It is very unlikely to case vibration or
    shimmy unless the overtorque is so high that you break several lug studs
    or the undertorque so low that several lug nuts come loose.

    You seem prone to exaggeration. :)

    Um. If there was a manual, I probably read it. I don't recall any
    specific instructions on storage. I'll check tomorrow. Does it
    need to be set to zero or something?

    Yes, generally you want to release pressure on the spring so it doesn't
    take a set with age and throw off the torque settings.

  8. It's the info that came out on the service bulletin on my 2004 Sonata.
    Bulletin number 04-50-005.
    Most shops don't look up each and every vehicle to see if there's a
    setting for the lug nuts. And I never said it was hard, just that I
    make ANY shop that's going to take a wheel off of my car aware of this

    You said it was a PITA, which generally indicates that something is hard
    to do. If it was easy, it wouldn't be a PITA.

    Then you said there should be a recall. A recall because a mechanic
    can't look up a torque value? Why?

    Do you have a copy of the SB? They really said that improper torque of
    lug nuts can cause all of the issues you listed?

    Voyager, Nov 9, 2009

  10. Yes, the SB says all that. After re-reading it, the only thing it
    doesn't mention is the bearing. As for it being a PITA, it is. But not
    for me, I don't rotate my own tires. I get free rotation and
    It a pain because it's something I have to watch to make sure the
    mechanic does it properly. Here's a link to the SB.

    Seems fairly benign if a little on the sensational side. However, I
    still don't see why it is a PITA. Torquing the lug nuts on a Hyundai
    looks no different to me than any other car. I still don't see the
    reason for your claim for a recall.

    It *is* no different than any other car. It's the mechanic's job to
    know the proper torque or to look it up-- on every car on which he (re)
    installs wheels. Practically speaking, most cars are 80 or 100 lb-ft,
    so remembering the exceptions isn't that difficult. For those that
    have trouble remembering the exceptions, there are books and charts
    that have this information.

    Similarly, a recall does nothing to insure the next mechanic that
    works on your car torques the wheels correctly. If your mechanic
    cannot be trusted to properly torque your wheels, methinks you need
    another mechanic.
