How far in the tube is the seal? There might be one on the retaining plate that bolts the axle to the tube, but I really do not think that I have a seal inside of the tube. Everything else on this car was wrong when I got it, so seals missing would not be a big shocker. I'll pull one of the axles this weekend and take a look. With the lack of a working motor, it should free up my schedule a little.
