Just had my newly installed front end aligned by my local shop. Looked under there today and staring at me was all the brand new components and all these nice grease fittings and none of them had any grease coming out of them?
IMO, a "good" mechanic will wipe clean the zirks after greasing so dirt and grime doesn't accumulate on the grease fittings.. So it could be they were greased and wiped clean.
Try putting some grease in a couple and see if they are dry.
