c2050 squeaking noise only in full color

i have replaced the lubricant bars of all color pcu's with the new springs.
No good.

As I said earlier in this thead the best way is to simply replace the PCU & fit the mod springs while you're at it. Or as I do simply explain to the user due to the age of the machine they will have to expect a few minor issues!

I'm not experimenting with this issue anyome, you should not. You must replace all pcu's.
