Thanks for reassuring my thoughts. My problem is slightly different from OPs. I can see why in his problem, with a bending/broken cap, the slack won't be sufficient thus a replacement cap would be needed.
In my problem, I've already set the slack and tightened the axle; however, I realized the other day my right cap is missing. Upon research I learned I've been missing a nut on both caps; they've only always had one. I ordered replacement parts but wanted to make sure it was safe to continue riding until they came in.
