hey guy got a 2005 cobalt ss. i get this hard clunk when shifting and running over bumps. already replaced control arm bushings. now when i have a buddy hold brake and move car the whole strut tower moves??? is this a sign of a blown strut or the strut tower??? what are the symptoms of a bad strut mount?? would a bad strut mount move the whole tower??

 

are the strut tower bolts snapped ?

check the 2 bolts that connect the strut to the Knuckle ....

the clunk is prbly your endlinks, one might be broken if it moves, take a wheel off an look.

 

the end links look good not busted. the tower bolts look okay but i need to tighten them down and see if they spin to check to see if they are broken. just weird on how the strut moves near the knuckle

 

make sure you torque them, they should not move at all.
