2005 Equinox LS shuddering on highway
2005 chevy equinox ls fwd. this just started a few days ago. ill be on the
highway and all is good. then all of a sudden the car shudders like crazy. feels
more from the rear end but im not sure. even my rearview mirror vibrates. im
only going 65mph. i slow down to 55-60 and it still does it. then after a few
minutes its back to driving normal again.

tires it would do it all the time. not sure need help
