Hey guys, im new here and just bought a 1999 jeep cherokee classic with 161,000 miles. My question is the engine or an accessory has a loud weerrring sound coming from it. Any place i should look first?


Also i have a ses light on and no overdrive sometimes, any ideas would

 

Might be your a/c pump goin out and welcome to the site i'm sure some one will help you better than i did

 

Mine is quite loud as well i have located it to the AC pump pulley if you can lube it up it might help sometimes dirt and crap gets up in there

 

Welcome to CF from Dan in Tenn.! It could be any one of your accessories. An old way to isolate the noise is to take a 2 foot piece of stick or whatever and, while watching out for the belt, hold one end to your ear and touch the other end on the AC compressor or whatever(stay away from the belt). Sound will travel through the stick extremely well and by going to each accessory in turn, you'll find the offending component. My late father taught me that over 40 years ago.

 

Check the wee plastic idler pulley first... I bet you don't go any further

 

my bud had a squealing idler pulley before we set out on a two hundred and fifty mile trip. two hundred and forty miles into the trip while im driving behind him i see his pulley com flying out from underneath his f150 and she was flying almost creamed a honda civic long story short fix it

 

I have a similar sound but it sounds like it is coming from the clutch fan.

 

found out what the noise was today. I was driving down a back road and it started squealing really loud, then the alternator froze up, threw the belt and ripped the fan shroud off Went to the local oriellys and got all new stuff, $243 down the drain.

Anybody have any ideas where i should look for my random no overdrive (sometimes its there sometimes not)?

 

Check for any stored codes since the light has been on. Procedure given here> http://jeephorizons.com/phpbb/viewtopic.php?t=2719

 

Well at least you have 2 less things to go wrong for a while.

 

the overdrive may be an nss problem, it controllls all transmission functions
