Small puddles under the front diff and ON the front diff. Coolant level slow drop. I figured "water pump". 4.0 with 146k. Have a new pump, pulled the fan, shroud, belt...weep hole is dry, bearing has zero play, and i mean ZERO. Looks like a weep/seep at the upper rad hose where it connects to the thermostat housing. Worm drive hose clamp was goofy taking it off - the screw backed out instead of loosening the clamp. Pulled the housing and cleaned it, doesn't look cracked. At this point... *her* 06 TJ, coolant leak, what would you do?
