Hello all,
Scratching my head on this one. 2003 LS v8, the car has of late occasionally produced a very brief shudder and sound, sort of like the sound when you drift onto rumble strips on the side of the road at speed. Only happens infrequently, but spontaneously and without apparent cause. Sometimes it's at highway speed traveling on a straight road, or turning at slow speed in a parking garage, or going over a slight bump in the road in a residential neighborhood. Doesn't last more than a fraction of a second. Can't predict when it will occur but something is clearly causing it. My first guess was ABS grabbing momentarily, but there's never a pull. I thought maybe a blown strut, but they appear OK, they bounce back just fine and aren't leaking so far as I can see. Now I'm thinking perhaps a suspension bushing or some other suspension part is failing, but that's just of course a guess. Anyone run into something like this? Thanks for any insight or suggestions on a potential cause.
