Replacement Bearing Kit for a Harbor Freight 90154 Trailer
Updated 11/04/2025 | Published 10/02/2025
Question:
I have a Harbor Freight trailer, item number 90154. What hub assembly is compatible with this trailer? The bearings show 30205/P6, QYDB, and ZM stamped on them. I also need to know which grease seal is compatible as well. Thanks

Hey Kevin!
Your 30205 bearing number isn't a common bearing type, but that's pretty normal for a Harbor Freight trailer.
If you can measure the spindle on your axle at the specified locations in the attached photo I can see if we can get you setup with some replacement bearings and grease seals.
Let me know what you find and I'll be more than happy to help out!
