Levo Gen 3 Slip under load

[Titaniumdean]

Hey a problem I had before has reoccurred , I have a slip in the gears under heavy load followed by a large pinging sound coming from the cassette. Here in Germany you lose the bike for about three weeks for repairs so put it in and turned out to be the cassette loose on the hub, bikes done 2000km on original gearing, all good, done about 100km and it’s started again, they said chain and cassette were fine, does this sound like a rear hub issue and is it commonplace? Was considering doing it myself but heard it’s complex?
Thanks in advance

I'd start by using a chain checker to check if the chain has stretched and needs to be replaced. If it's ok, then the next thing I'd do is to clean and service the free hub. There will be a guide on how to do it, based on which model of wheel that you've got. Neither is particularly difficult, but do require some specialist tools. Servicing the free hub does mean a few small parts potentially bouncing around your workshop...

Oh, forgot to add, I'd make sure that everything, including the cassette was clean as well.

Is the bike an eMTB used offroad and done 2,000km on the same chain and cassette?

If so then the chain might have worn past the normal replacement point (0.5% stretch) and progressively damaged the cassette, so in this event it is time for a new chain and cassette.
