I got this a few times. I tried alot of basic stuff but it doesnt work right away. First off, you look small so you probably dont have muscles ( you might think you do ) but get your dad, or someone alot older that has stamina. Get that person to SIMPLY get a HAMMER, and a FLAT HEAD SCREW DRIVER.
FIRST OFF, BREAK THAT 1/2 A BEARING ON THE OTHER SIDE, IT WILL MAKE IT EASY.
Take that SCREW DRIVER and put it in the wheel through the opposite side of the bearing RING you want to take out. Then, get that person with the muscles to literally place the SCREW DRIVER on the little lip the bearing ring has INSIDE THE WHEEL. And get that person to take the HAMMER, and literally BEAT THE SHIT out of that ring. It will eventually fall out. It might take a few hours..but the wheel is basically new. Plus I NEVER had this problem with eagles, usually just protos.
Good Luck Darth Vador
