Cassette moving on freewheel issue

Was having crazy shifting problems after a solid crash at Creek last week. Went to check my indexing yesterday and noticed the cassette actually moving laterally a few millimeters everytime I shift, particularly on the larger side of the cassette. Thought the cassette might just be loose...but it’s not. Is my freewheel shot? Should mention this is a SRAM GX 1x11 setup... I haven’t dealt with that XD driver much as I’ve always owned Shimano.... Any suggestions?

Which hub?
My CX bike had a plastic spacer which got crushed, replaced it with metal solved problem

It’s a Formula hub...came on the bike and I’m not real familiar with the company.

Actually just made some progress and other strange discoveries.... the end cap of the XD drive body was loose and the entire drive body and cassette assembly slid off the axle as one... put it back in and tightened up the axle now the play is gone. the weird discovery is that something has banged up the splines on the free hub and I can’t get a cassette tool to insert now...so it looks like this cassette/drive body will have to be replaced together when the time comes.

-Some hubs the endcaps can loosen a little bit. Easy to check by hand when putting the wheel back in when taken out. Just turn clockwise to see if they tighten.
-OEM Formula hubs (are there other types?) are known to have broken axles. Sounds like this isn't your issue if you were able to tighten up the endcaps and solve the problem.
-Banged up splines is extremely common. A higher end cassette that there's a big aluminum carrier helps. My thought is if the splines are banged up, I push/hit/hammer the cassette on harder, it's damaged anyway. Only real downside is it's hard to get it OFF.

Yeah I think the main issue was the end caps. I did end up hammering the cassette tool in a bit and now I don’t think I’ll ever get it off the free hub again. Good news is the play is gone and everything feels nice and snug again. It’s not 100% yet but should be able to get there with a little more tweaking.

Anyone recommend a better quality XD driver body that’s compatible with the GX 1x11 cassette?

Use these tips with a large grain of salt, as all of the bikes and spare wheels in his place are currently broken.:)

So this was the first thing I saw on Instagram today. I think we’re on to something here...

This was mid stage at EWS and he still took 5th. Smash your wheels with a hammer and you, too, can be a winner!
