Front right bearing and strut

I have a 2003 Toyota Celica 4 cylinder car. Recently I had my right front passenger strut replaced due to leaking of the hydraulic oil. Coudnt make it to Firestone autoshop so I took it to lil autoshop near my house. They replace the "strut" and the "bearing". After that, I took it for test drive on highway and car starting shaking around/at 80 mph. Plus, I hear some kind of "grinding" noise from the front right side of car. Took it to Firestone, did the wheel balance and wheel alignment and the shaking went away but the grinding noise I can still hear lil bit. Is the noise coming from the "bearing" that the lil autoshop replaced wrong or does it need to be greased up before installment? I think the lil autoshop did a mistake when replacing the bearing. Any advice? Thanks :)
