Wobbly Cassette

So I’ve switched out my son’s drive train. Changed from 9 speed to 10 speed. But I’m left with a wobbly cassette. Pretty sure I need to stick a spacer behind the cassette onto the freehub. I tried with a 2mm spacer but could get the last cog on. I’ve ordered a set that includes a 1mm and a 1.5mm spacer. I’m hoping this should solve it. But am I missing anything else?

    I had to put a 1.85mm spacer on a road width freehub to fit an 11speed mtb cassette for the same reason.

    A narrower spacer width would do providing the small cog still sits a little bitfurther out from the end of the freehub which allows max thread engagement and proper tightening of the cassette without the lockring bottoming out first.

    Thought I’d give an update. Spacers were bought and tried but then did nothing. Turns out the cassette was wobbly due to a knackered freehub. Had to get the LBS to take the freehub off, then began the process of locating new one. Found one (eventually) on Amazon! It was a Raleigh freehub at only £11.99 bargain. Freehub purchased. Thanks Prime for next day. Fitted, greased and all working well. So the lad is back shreading the narr. Ha ha
