Your first bearing pack should be done soon, I did mine at 15 months and about 4500 miles. Found leaking seals and loose bushings in the actuating arm. Dexter replaced the complete assemblies under there 2 year warrantee program. Contact Dexter directly, I filled out the warrantee form online with pictures, they responded quickly, the only question I asked was; Is this a safety Issue? End of conversation.
Sorry about the upside down picture!
