The bolt that holds them is very tight, but very tight, but there is play there and it moves up and down on that bolt if I rock the wheel. Is that normal or should there be zero play? Both wheels demonstrate this issue. The left wheel tends to rumble or vibrate more noticeable when I ride, no issue wit the right wheel, and maybe I mostly hearing it against the fender. But when I hold the wheel as described it's the disc rotor which restricts the movement. I"m worried this is dangerous and, if so, don't know what needs to be replaced or fixed. My mechanic is not a recumbent mechanic, just a talented regular bike mechanic. Appreciate any help asap. thanks.
I'm not a qualified trike mechanic, so the best I can do is point you to the recumbent trike forum where you can find some real help:

Good luck. On first read, it might be the ball and socket part of the tie rod attached to the kingpin or something like that, which is worn out. Or maybe this is the dreaded "death wobble" of a front end that is not aligned properly? But those are two wild guesses.
