    I have a 97 SL1 and was wondering how you know if your motor mounts
    need replacing. The car idles kinda rough and has more vibration in
    drive now compared to what it used to a few years back.

    1) If you haven't changed them before, then they probably need to be
    2) From your description, the upper motor mount (actually called the
    torque axis mount or TAM) would be the first thing I'd check.
    3) If there's more than about 1/4" gap between the metal and rubber
    parts of your TAM, it's bad.

    Are the mounts available from a parts dealer or only from Saturn?

    Don't know. I bought mine from Saturn. It's actually just one mount,
    and I paid $94.75 for it with tax and new, longer studs. They told me
    it had been redesigned, and the studs had to be changed. Hopefully that
    means it will last longer.

    I had to change mine on the 98 SL at about 100,000 miles. Didn't notice a
    lot of vibration, but my mechanic suggested the replacement due to age &

    got mine from advance auto it was $56 dollars.. There is also a lower
    transmission mount on the oppisite side that I would change also.

    You probably do need an upper motor mount especially if it's never been
    changed out. In my experience it's an every 3-to-5 years thing.

    Vibration is probably the upper motor mount. You can probably see a gap
    in the top as it has collapsed.

    Clunking on acceleration is one or more of the lower motor dogbone
    mounts or the transaxle mount. Here what I saw was swollen rubber parts
    from previous oil leaks on my wife's 92 SL1. You can see these mounts
    by taking off the wheel well cover.
