Review on Timken 30205M Wheel Bearing Race by Mark Meyer

I used these bearings to replace crappy Chinese bearings that originally came with my Harbor Freight 4x8 folding trailer with 8" wheels. The same bearing is used in the 12" version from my research. These Timken bearings are made in Poland and are of good quality. You will need 2 of these blocks per hub, 4 total if you are changing all the bearings on a trailer I would advise getting a brand name bearing like Timken for trailer bearings as it is a HUGE problem if they fail, especially with custom made bearings like these , which you will NOT find in an auto parts store in such quantity that you have to drive again.
