    Many times the squeal in the belt area is caused by the idler pully. There is permentantly lubricated bearing that does dry out and squeal. If you have a good belt properly adjusted and sure it is not slipping spray a little WD-40 on the back of the pulley and if the sound changes replace the pully as a unit or if you have the skills change just the bearing. I have done this on my own XJ my daughter and my sons. Good luck and keep JEEPIN.

    I have an 05 JGC with the 4.7, 5 speed tranny, 2wd. My problem is that when I go into reverse, it make a loud clunking noise like the universal joint(s) are bad. Anyone else have/had this problem, and if so, what was the cause and how did you fix it??? Thanks for any time and info on this. Just to let you know, this vehicle has only been driven on the street, and NEVER thrashed on, although I do "blow the carbon" out of it every blue moon or so. ;)

    Thanks for the link. Mine is different, it only does it when I go into reverse. It don't do it in Drive, nor does it do it while I'm driving, only when I go into reverse. It sounds like it is the universal joint, but with less than 30k on the odometer, I can't see it going bad. The Jeep never see's any rain, because it never rains here to speak of. I guess I'll get it lubed and tell them to make sure they get the uni joint real good. If it does it after that, I'm off to the dealer with it. Thanks for the time and info on this, it's greatly appreciated. :D

    could be where the drive shaft goes together the splines get dry and donot move freely when you put jeep in reverse the axel will shift a smig ane pull on the splines try to lube them and go from there

    That makes sense. Thanks for the reply, I sometimes worry where there is no need to, but I would hate for it to drop while my GF was on the highway doing 80mph. I gotta crawl under there and see if I can fine the grease zerk, and give it a shot to see if it helps any. Thanks again for the time and info, it's greatly appreciated. :)
  • I have a 1994 Jeep Grand Cherokee Laredo with the 4.0L inline-6 with around 75K miles. It doesn't get driven very much, it sits in my driveway at home while am at school during the school year, and recently when I started it up after it had been sitting for a few weeks it started making weird noises. There is a faint clicking/rattling noise that comes from the engine, almost makes the engine sound like a diesel. Other than the noise, there are no indications that anything is wrong, the engine runs smoothly and the power delivery is good. The oil pressure does run slightly high (3/4 of the dial for the first 15 minutes or so that the car is running), but I did just have the engine oil changed, so that might account for the higher than average oil pressure. I was just wondering if anyone might have any idea as to what might be causing the noise? Thanks for the help.

    Heres what I did on my 2002 jeep with the same engine : drain the oil, take some carb cleaner with the little tube attached and spray the cleaner up towards the oil pump pickup screen,let the crank case drain well,I added 1 quart of Riselone and topped off with 5qts of 5w-30 oil.I used a good anti siphone oil filter. I had the same proplem as you 1 year ago and never had the problem come back ! Hope I was a help !

    sounds as if you lifters are bleading down
    i would try a can of SEA FOAM in the crank case to see if will clean lifters
    or turn up radio

    I have a 2004 JGC and when backing up I hear a loud squeaking noise? It only happpens when backing up NOT when going forward. It also happens when the brakes are NOT engaged. Thoughts?

    Thanks, tidester, but none of those are like what I am experiencing.
  • tuggajbtuggajb Posts: 646
    when you reverse and just touch the brake dose it go away?
  • jeepinsljeepinsl Posts: 5
    No. In fact, it makes the noise as I am letting off of the brake as well as after I let completely off of the brake.
  • tuggajbtuggajb Posts: 646
    ok try and put the emergancy brake on a little and see if noise goes away

    My '01 JGC Laredo made the same noise, replaced the front hub bearing and the noise continued, replaced the same hub bearing again and it hasn't done it for the last 2 years. I think maybe the dealer replaced it with a new/bad part as they were footing the bill for it. Hope this helps.

    Has anyone had this problem with there jeep?When I am driving around 60mph there is a popping sound coming from the front end when I throttle to go faster then it goes away and comes back around 70ish when you start to throttle at first it only did it going up hills now it does it all the time.I climbed underneath and found the tie rod end worn I thought I solved the problem but it is still there.The drivers side boot is torn I am leaning towards that or the hub bearing.I also notice short drive shaft from the front end towards the back has end play in it.Need some advice before I start changing everything just like the jeep dealership would.....this maybe quensidental(sp)but the problem started shortly after having the dealer replace the radiator fan.......
  • tuggajbtuggajb Posts: 646
    first what year jeep

    torn boot could have ruined your axel shaft will need to replace that shaft rebuilt one is ok

    drive shaft should have no play when you wiggle drive shaft look close at where it hookes up to your front axel housing if flange moves in out or up down have bad pinion berrings will need to be fixed soon

    thks tug..
    the cherokee is a 99.the boot is torn I will be taken it apart this weekend.Driveshaft there is endplay but no up and down play what so ever....I am starting to wonder if they sound is caused by a pcv valve or vacuum leak as it seeemed to happen only when you put a load on the vehicle.I havent been able to find part #s for the pcv it is cheap enough and the jeep has 120m.on it.....
  • tuggajbtuggajb Posts: 646
    realy should not have in out play in front drive shaft eather
    look real good at front flange by punkin an the flang that goes into trans fer case

    when you put load on jeep pinion move in if you have bad berings in punkin
  • jsimjsim Posts: 6
    I will do that tug,thks.......I was under the jeep last night and now i found another problem,hope to hell this is the original problem.The pinion shaft coming out of the rear diff.is totally loose it has unbelievable amount of up and down movement.I went to jeep dealership and ordered a seal and crush spacer.I am going to see if this tightens it up.I am scared ...... less that there maybe alot of damage in the rear end.I will post next week after vacation how it turned out,if that was the problem and it was transferring to the front.Then I will do the boot on the front axle after checking the bearing and hopefully the jeep will be as good as new.Price for a new rear end in canada is 3750...lol from the dealership that is not installed
  • jsimjsim Posts: 6
    hey gooo did you ever find what the problem was?Mine is doing the samething.Only when accelerating
  • tuggajbtuggajb Posts: 646
    have all the spec on install of crush sleave and such?
  • i have a 2003 jeep grand cherokee with a 4.0l. when put into reverse regardless of appling brakes or not the truck makes a very very loud squeek also. i have traced it to the transmisssion or transfer case, but cannot figure out what it is. it drives me CRAZY!!!!!!!
  • jeepinsljeepinsl Posts: 5
    Have you taken it to a transmission shop to get an estimate for repairs? I want it fixed! I am tired of people looking at me while my car squeaks as I back up!
  • I took it to my local jeep dealer to see if they could figure it out and they shrugged their shoulders and said they would have to tear it apart and try to figure out what it could be. they were clueless about the noise. i posted a forum on here back a few months ago and got no responces from anyone, so now there are two of us with this problem. sorry i have no info for you. i changed my u-joints and it stopped for a week and a half and then started doing it again????
  • tuggajbtuggajb Posts: 646
    I would not think it is the trans or transfer some where in the u joints area
