While my wife was doing a load in the dryer, it started making a loud noise like the drum was rubbing or out of balance. After taking the drum out, I found the two drum rollers were stiff and hard to turn(culprit found). After I took the first roller off, I cleaned the inside of it with Brake Cleaner as well as the post it spins on. After doing this it now spins somewhat freely. Can I use some kind of lubricant(ie...Prestone Silicone Lubricant or Vaseline) on it to help it spin? I will try to post pics in the comments
