man I truly am learning stuff the hard way. I got rid of the old calipers already so I will have to go get a new one....sucks.
about the races, I am not sure about that. Maybe they asked about it? I dont remember but I just reused the old bearings on the new racings. But now I have new bearings on new racings. Just how it came to be I guess.
Man it's ok. I'm a pac rat.. my wife gets mad because I dont throw old parts away. I always kept them for a just in case scenario. I would follow Erik the Awful advise. Whenever your ready to mess with it. Btw it happens to all of us. One of my dumbest moments was one day I got new steel rims for the truck. Few month later I started noticing a clunking sound that I only got when it was wet. Drove me insane. Checked everything on my front end replaced parts that looked warn... I was clueless... could not find the clunking and mine is 2wd so no front CV joints.. my wife was like try swapping the tire. Didnt listen for a few weeks. Finally I gave up and said screw it so I swapped the tires and sure enough she was right.... turned out one of my steel trims weld was cracked and was making that clunking sound... felt dumb and wasted so much time. Learned my lesson.....
