Guys 88 xj 4.0
can not pinpoint belt squeel... So far i have replaced ps pump, idler, water pump
and belt
The squeel is a high pitched and increases with RPM then drops off after a certain RPM .. it is very loud... nothing is binding and i can not figure out what its comming from..
Only bearings left are the mechanical fan and the alternator... I dont like to replace parts like this to find a problem.. its no fun... but i am ready to let the stealership find the source... any ideas or hints... i tried listening around the bay for the sound couldnt hear the exact source though it soujnds like its comming from the water pump area
with the fan belt removed i freewheeld everything and nothing seems to sound... another thing i tried even was "motoring" the engine with negative results
