Well, the part I thought was bad, well the fifth or sixth part I though was bad, must not have been, the noise is bad. The only parts I haven't replaced yet is the water pump and alternator. Today I replaced the bearing in the air condenser pulley, not the problem. I only had to go to the bearing place three times to get the correct bearing, in the panel truck. The bearing cost $30, I avoided forking out $300 for a new compressor plus paying for the system to be purged, flushed and recharged. I suppose it'll turn out to be the $165 alternator. I'm about to drive this beast off a cliff somewhere.
Old trucks, it's a sickness-one I hope they never find a cure for!
