The slewing noise of the HEQ5 can be reduced substantially with some TLC. I replaced the lubricant and adjusted the gear mesh (and especially the play in the transfer gear "bearing"). The mount is much quieter now, even though it still has its resonances at certain speeds.
Cheers

EDIT Oh, you were referring to the noise it makes when you stall it… That one is terrible, I agree. Hopefully not heard very often
