Red? interesting. Did you get it reanodized yourself?
I've been having troubles with bearings not having sheilds on them, the previous owner removed them from both sides on all bearings, meaning some very stuck bearings after a wet and gritty race day a couple weeks ago. I've now got rubber sealed versions for the diffs and will replace others as I can afford it. It was causing awful handling at first, after soaking the bearings and reoiling them, the big bearings are still bad.
