So I took my Shimano Deore CS-M5100 cassette off for cleaning. After putting it back and riding for 20 miles, both the cluster of cogs and individual cogs were able to be moved by hand on the freehub. It was as if the lock ring had come loose allowing the cogs to move within the splines of the freehub. All spacers are present and in the correct place, the lock ring was correctly torqued to 40NM. Even at 60NM, the issue persists.

Thoughts on the issue? Should I even be worried? Solutions? LBS suggested a new lock ring?
