The Dexter Trailer Hub # DX46XR uses a 2.72" grease cap. We do sell a cap in this size. For that I recommend the Trailer Hub Grease Cap # TRU66FR. This cap is made for an easy-lube axle, so it includes the cap and the removable rubber plug.

Answer 7

For a 5,200 lb trailer axle hub with 6 lugs the correct size dust cap/cover is 2.44 inches like the TruRyde cover part #DC250L-DCRP. Sounds like what you ordered was the version for the 8 lug hubs which is a slightly larger size.
