My 2005 Laredo is beginning to make a light rattling noise, and it sounds like it's coming from one of the pulleys. Could this be the water pump going out? The Jeep has 58K miles.

there are 2 engines 2.0 / 2.3 and they both have chains if you are getting a rattling sound from the cover front the guides are worn or the chain tensioner are worn the guides have nylon chain runners on them and if they wear down the chain is rubbing against the metal arm that the nylon is mounted on if this is a high mileage motor I would suspect this because the chain can not be kept tight because of the worn guides have now caused the chain to be slack and its rubbing against the front engine cover but you must be sure before opening it up that its not the water pump or belt tensioner pulleys making the noise if that's what your hearing the water pump will sound like a marble tumbling around in a can the pulley's will sound like constant friction grinding of the dry bearing inside against the bearing race there also may be a chirping sound of the belt being made from it grabbing each time the bearing catches inside and releases the chain will sound like a constant rattling as if you drag a metal chain on a ceramic tile floor and engine running condition will be rough idling and missing a bit especially when you come to an abrupt stop it may stall
there are several items running that can produce a noise
the water pump bearing will be a grumble or a tinny rattle , the idler pulleys will be a rattle, the ac pulley is on a bearing separate to the ac operation and is running all the time and the problem noise could be from that bearing
the alternator bearing will make a medium pitch rumble and if you have a viscous ( clutch hub) fan hub the bearings in it will produce a noise
an accredited mechanical shop will have a stethoscope and a good mechanic will be able to determine exactly where the noise is coming from
The technique I always used to identify where such a noise was coming from was to use a very long screwdriver (2 feet long), while the engine is running. CAREFULLY touch the screwdriver end to each pulley or other object under the hood, and put your ear to the handle. The device making the noise will become very clear.
It could be AC pump/clutch, alternator, water pump, power steering pump, etc.
Automatic or manual trans? Manual trans could be throwout bearing. Other moving parts at idle that have bearings - alternator, a/c compressor, water pump. Auto parts store or harbor freight sells stethoscope to listen to stuff like that. Use it to determine where sound comes from. Careful when using near moving parts.
sounds to me from the brief description like you have either a water pump rattling, or a timing chain coming slack. Is the noise coming from the alternator? Never grease pulleys, ever. also the stop squeak spray is bad for your belts. Don't know why they even sell it. If you listen carefully you may be able to pin point the rattle. Is this a tick tick tick, or a rattle rattle rattle? Does sound like a water pump rattle or timing chain slap though. Hope this helps
lots of parts, alternator, water pump, a/c compressor lower area . many of them are on the serpentine belt. the pulleys and tensioner can make rattles. you need to confirm which part has the rattle or vibration, use a stick or screw driver. touch one end on the part and the other near your temple...any noise/vibration coming through?
fiind which one it is. lower noise on the crank can also sound like its coming from up front and that's a deep rattle.
not likely possibly the cover for torque converter may be loose. if rattling coming from pass. side may be belt tensioner/or water pump. to check shut engine off remove serp. belt check water pump pulley for play by wiggling back an forth do same with belt tensioner. check trans fluid level while on level surface engine warm&running tranny in park. some gm cars have had problems with crank shaft pulleys making rattling noise also.
