noise is complex. the FSM chapter 0? IIRC # is noise and is lacking.
1: find what area makes that noise, its not hard, there are cheap tools to do that ,try a wired or wireless sonic- ear. they cost about $50, you can even have friend drive and you listen.
2: you can use a rubber hose to ear to find the source. (under dash) under hood? (header shield behind exh manifold tubes cracked?)
3: if in the engine bay, you can drop belts. or put pressure on all (levers) to all engine mounted devices, to see if this pressure, stops the rattle. (shim the cat shield?.)
4: Ujoints, feel them flex them look for red rust dust , wicking from joint seams. they must not have play in the STAR. to yoke at all.
5: some 3speed, 2wd the tail shaft bushing fails, yes, a crappy bushing sold for 99cents too. 3sp is no class act.
you can drop all drive belts, even the water pump, start engine and test for 1min, so it dont overheat from dead cold.
the stethoscope (HF for $5) you can listen too all accessory bearings, they purr , listen to them all , you will see who sounds wrong fast.
I can drive and listen to gear box out shaft bearings, or axles. with the electronic ear. even driving.
last , i dropped in a new motor. and it started and run perfect but the banging sound, was the same as the last motor with a bad #4 rod bearing, MY HAIR stood on end.
the exhaust flange device was cracked and i missed that. the collector was boucning against the header,
also next kick 16v had 2 broken main intake main air pipe mounts broken, not only did it bank but sucks air and wrecked the MAF readings.
use levers and shims to find offending parts suspect.
jam them in and see if noise abates or changes.
the tools are worth 1/2 hr , shop labor, so IMO , are free. (and at the end, you get to keep the tool. and could sell it, and make all this free) Amazon sells them.
one such tool is the Steelman, 97220
