Japanese term

回転ガタ

Japanese to English Tech/Engineering Automotive / Cars & Trucks Drive shaft/propeller shaft mechanics
Any ideas on this one?

I know "ガタ" in terms of drive shafts is "excessive play", but I can't find a suitable term
that incorporates "回転"..."rotational excessive play" doesn't seem to be the correct term.

In this case we're talking about drive shaft joints, but I suspect there's a general term that can
be used for "回転ガタ".

Appreciate any feedback

Note from asker:
Thanks for your reply. Yes, I usually use "rattle" for "ガタ" as well. However, in the case of propeller/drive shafts, the term "play" seems to be standard when describing looseness. I finally settled on "rotational play" when describing this phenomenon in drive shafts.
Peer comment(s):

agree Derek Newpor (X) : Both answers seem reasonable. Note Interpress gives "がた" as "rattle", so "rotational rattle" would also work.
