I'm wondering if someone can give me advice on this problem - Recently my
engine started vibrating excessively (esp. at higher speeds), whether in
neutral or on the freeway. I checked my right engine mount, which was soaked
in oil from an old cracked breather hose leaking on it (which I fixed) and
had the rubber tearing at the edges, so I replaced the mount. The left mount
appears to be in perfectly good condition, dry, and with shield in place.
However, the vibration is still there (although to a lesser extent, so I
guess the new mount helped a little).
So now I'm wondering if I should have replaced the left mount as well, even
though it seems to be in perfect working order, or if the engine shocks are
to blame. How can I know that the shocks are bad? I couldn't tell if they're
leaking anything because everything was so greasy down there (although I
cleaned it up now).
