So like many things it started simply enough. I had replaced the tires on our New To Use 5ver. While I had the wheels off I thought I should check the brake shoes. Once the drums were off I saw that the bearings could use some new grease. Fronts are easy enough but to do the inner bearings you must drive out the oil/grease seal over the bearings. First one popped right out using a just right sized socket to drive it out. But the second one the bearing cage broke and so now it was a deal of "well might as well replace all the bearings."  And thus started a long weekend of multiple trips to the auto parts store. I used O'Riellys because they could turn the rusty drums to make them clean and round again. They had the outer bearings and races, and got the grease seals in the same day. They even lent me a bearing driver kit that made putting the new races in super easy. But the inner bearings they sold me didn't come with the races in the package and when I found that out, they told me they could get them in by next week! So i tried other stores and found the whole bearing and race package at Napa, for less and a better SKF brand at that. OK, now we are cooking. But as I closed up everything I found that the grease seals are a real PITA to get in and buggered up the first two I had got at O'Riellys and so back to Napa for better seals again cheaper. The one thing that I hadn't found yet was the long skinny cotter pins that are needed to lock down the castle nut. So a trip to Lowes where I scored the last packet of 1/8 by 2 cotter pins for $0.75. Now it's all back together, brakes adjusted, just waiting to lower the trailer off the jack stands and torque the lug nuts.

So here is the moral to this long story, after two days and three stores, I now have new greased bearings. Scamp sells the complete Kit for wheel bearings for much less money than the collective hunting and foraging that I had to go thru. So IF you know you are going to be redoing your bearings, just order the kit, it's all there including the new washer and cotter keys, and you know they are the right parts.
