It's an easy job to pull at least the upper triple off and have a look. If water got in there they could easily be corroded. You'll want to know before trying to re-torque them. Something happened in there to cause clearance issues and I'd rather find out in the garage with a beer, than on the road at 60KPH.
IMO, I'd just buy new tapered bearings (they are cheap) and swap them in while it's apart. No harm done.
