Blown Strut Mounts
Bushings wear up at a much higher rate. The strut is not leveled. The strut might pop-out from the base, damaging your hood.
Stock / OEM
Check your springs, shocks, and the shock observers for failure or signs of excessive wear.
Lowered / Aftermarket
If your car is lowered and the strut mounts are regularly failing, you may want to consider running a set of KMAC camber plates. Be warned that the camber plates will redirect some of the force back to other components. Make sure that your strut tower is structurally sound.
When it comes to parts, the brand matters. Always use OEM strut mounts, do not use aftermarket parts. Especially if you have wheels that are over 17 inches.
