I have a pd sander that when you first set it on the wood, it takes off in a random direction.  You have to apply pressure to get it under control.  i need some advice on how to correct the problem as it did not do this when it was new.  I’ve checked the 4 plastic extensions, none broken.  I’m wondering if the bearing is bad or if the sanding pad needs to be replaced.  They both look fine now.  Thanks for your help.
