As the title says, a loud bang occurs and is felt through the rear right, sometimes up through the center tunnel/pass floorpan (no insulation or carpet) over some road bumps. Only a couple months and other repairs later, I am intrigued.

Shock tower bolts are secure, swaybar is clearing.

Mille Grazie
