Repacking Wheel Bearings
This may sound like a crazy question, but I'm serious. I understand the purpose of repacking wheel bearings (lubrication), but what I don't understand is if I can drive my truck without packing the bearings every year, what makes this necessary with a TT? If the technology is available for automotive, why isn't it applied to trailers? Boat trailers get submerged..makes sense to repack, but a trailer is exposed to the same conditions as a truck/car.
I'm sure I'm missing something....any info is appreciated.
