Both my axles were recently replaced and upgraded to the Ez-Lube hubs.
Trailer is a Sierra 38SP, 2006. It has alloy wheels with center caps. No holes in them to access the Rubber Cap or Zerk fitting. Meaning I have to remove wheels, which to me defeats the purpose. I asked the installer if we could just cutthe centers out of the dust covers to allow access. His response was No. I then asked if there were any dust covers designed for this and he said he hadn't heard of any.
Does anyone know of dust covers designed to access the Ez-Lube??
