need some help troubleshooting a problem

[hotairgypsy]

well for Christmas we traveled to Dallas from abq. 700 mile trip was uneventful until the last 100 miles or so. I felt a new metalish grind in the floor and gas pedal. I can hear it also but do not know where it is coming from. Does vary in intensity with reving the engine. In the last 5000 miles i have replaced the starter, alternator, power steering pump, serpentine belt, and tensioner and both pullies on the tensioner. It did not leave me stranded and we made it here. I let the truck sit overnight and checked it this morning. I remote started it while i was under hood and didnt notice anything out of the ordinary. Took it for a drive and can tell it was still there. Seemed to get more obvious as the truck warmed up. I suspect it is the water pump but do not know for sure. here are some pics of the pump from this morning. I am not seeing any puddles of antifreeze.

You have and side to side movement if you wiggle the fan?

Any chance we can get square on the cluster?

i took off the belt to feel for the movement in the pump and nothing seemed to be out of the ordinary.

I shipped you your cluster and you tracked it all the way to your home town then the post office got them self confused. Until I get it back we are at a standstill. I did my part and shipped it with tracking. I cannot control the people at the post office in your area. You have the tracking number and i have called and am waiting back for a call. I have told you this already. You are more than welcome to call the post office and see if they can get some answers since they are the ones not doing their job.

You might wanna call them back. The postmaster told me a week and a half ago it had been delivered back to you.

Put the belt back on and try to rotate the fan by hand. Should have resistance but should turn. If it's extremely hard to turn or won't turn, then the clutch is junk. I ran into this on an 03. The bearing locked up in the clutch and pretty much welded itself to the shaft. The noise wasn't there at idle but when you revved it up in neutral or got it under a load and got on it, it would screech/grind. Basically what was happening is the belt was slipping on the fan pulley because of the fan clutch being locked up.

i will check that...i am not getting any screeching but the grinding is there...

ok...just checked it with the belt installed and I can spin the fan pretty easy...not a whole lot of resistance. I took it a step further and disconnected the serpentine belt from the crank and started it. I felt great...didnt feel any weird vibration. so the vibration comes on with belt installed and stronger when warmed up. This removes long block, starter, and loose flywheel from the equation it seems...which is great.
