Default Noise difference between different JR NES-537 servos

I just bought 6 JR NES-537 standard-sized servos. 3 of them have very quiet movement, however the other 3 are noticeably louder. Should I be worried about the noise difference, or is this fairly normal between different servos?

Opened the servos up and regreased them with white lithium grease. Everything is good now.

537's are the cheapest servos JR makes. You get what you paid for. The molding of the cheap gearsets are not perfect. The growl noise is caused by the teeth "bottoming out". On metal gears servos this may sound more like a gritty noise. Adding grease sometimes helps, but the best thing to do is just use the servos and as they wear in, the sound will get quieter. The grease Dennis at Horizon told me they use is Tamiya ceramic grease. Only use a tiny bit. The good news is, I have never heard of this noise causing any problem at all.
