You can check to see if it's the mains bearings by getting
under the jeep and trying to move the hb forward and back
from the engine. it shouldn't travel more than about 1/16"
The signs are
worn belt (from misalignment)
rough idle (since it's not balancing properly)
rubbing bits (like your fan blade hitting it)
The HB is two bits of iron sammiching a bit of rubber.
That rubber is what cracks and slips.
