There appears to be some play in my DT Swiss 240 freehub - if I hold the largest cassette sprocket I can rock/flex it side to side about 1.5mm. When I opened up and cleaned/greased a month ago I could feel some movement in the freehub body.

Is this normal movement and not worn?
Time for a new freehub body?

240s Road Disc hubs have about 20000km+ of 4 season use.
Dura Ace cassette is 2000km old.

I’m chasing the cause of drivechain noise when in the largest 3 cassette sprockets + little ring + steep climbs. Will be regreasing pedal threads, through axles, axle/frame/dropouts, chain ring bolts, hanger, check b-screw etc tomorrow. Drivechain already spotless. BB pulled and serviced. Thought maybe freehub was part of the problem.

Check your cassette spider. The last three cogs on a dura ace cassette are held together with a carbon/plastic carrier which can crack under extreme loads (i.e. steep UK climbs)

I've cracked one myself - it's a well known flaw. Shimano will warranty it though if you're the original owner.

Yeah, I’d read about that and checked the cassette first thing this morning. Marine greased the splines and between each block of cogs. With that and adjusting the chainset preload things have quietened down a little... for now.
