Hey gang.
Back to my son's 2001 Grand Prix GT with the 3800 motor.
He's got a "shaking" that feels like the motor, not suspension/front end, that starts around 45mph,
then lasts until 55mph or so, where it smooths back out.
When I say shaking, I mean far more than just a shimmy - its a very pronounced shake.
So far, we replaced:
front sway bar (it was broke)
both motor mounts (trans mount was completely blown out, other one actually was in pretty good shape - replaced
both anyway)
right and left tie rod ends
top torque strut - it was broke
4 new tires
front end and rear end alignment
However, the shaking still continues.
Anyone have any other ideas as to what it might be? We've kind of run out of ideas here.
Thanks!
