Front Top Plates Bushing Noise

For three consecutive years I’ve had the same problem which basically is, that my front top plates bushing are rattling when the car goes over road cracks or bumps and therefore needs to be greased or changed due to our (Canadian) extreme weather conditions
(-10 F winter/ 90 F summer) But this year, I lowered my coils and GM says it will no longer cover the charges to fix my top plate bushing problems.

Does anyone have that problem?
Is there a way to avoid that problem?

Please provide feedback ….

Thanks
