It's good to know I've got plenty of life left in my 10 year older XJ. Replace your belt and the squeal will disappear.

Drove home, later that night tried to start it and it clicked once and then after that no sounds at all. The lights in the car do not go on or nothing on the dash, no sounds or lights. Disconnected the battery cables and mad sure they were clean, put back on and when you open the door the lights in the jeep are on. You turn the key and you see the cluster light up and here the door chime. Try to turn it over an you hear once click and nothing else. The light s are now off again in the car and no lights or sounds on the dash. Tried to jump start it Nothing. disconnected the negative cable on the battery and put it back on , open the door and and lights are back on, turn the key lights on dash are on again and door chimes, but only clicks once again and everything is off. No crankin action at all. Help What should I try.
Pull the cover off your relay/fuse box in the engine compartment. Look where your leads from your battery are going into that box giving it power. That's the cover that comes off not the main cover, under it are positive and negative terminals. I bet those are corroded. They're easy to overlook because they're covered up by that plastic cover.

I did. I have come to the conclusion that it's a design flaw. The way the belt routes around the crank is only about 90 degrees instead really grabbing that crank pulley by wrapping around it like 180 degrees like every other belt routing diagram I've seen. There is no other way to route the belt to get that good 180 degree bite on the crank. It is highly unlikey that any of the other pulleys are misaliged since that would be very noticable given the idler is tighened down after adjustment. Only thing to do is tighten the **** out it with caution.

Check fuse #17 for the O2 heater relay before moving forward on any O2 sensor replacement.

You could look here for ideas: http://www.jeepforum.com/forum/f46/x...-xj-xj-184475/

Put some belt dressing on there. It'll either fix it permanently or just make it not squeal for a little while

Remove the starter and check the solenoid.....or it could be the starter motor. The click is probably the solenoid working and the starter motor is shorting out. My bet is the starter is bad.

After 290,000 miles it's doubtful it's a design flaw. Mine has never squealed in the 22 years I've owned it since new....as long as the belt is in good condition and properly tightened. Have you ruled out worn pulley grooves? There are tools that can check this.

Well now that's a thought. If my crank pulley is not within spec I wonder how hard it would be to pull it off. Where can I get a gauge to check it, and the other pulleys?

Hope this helps if you have not fixed the problem yet.

If vehicle exhibits a rough idle, and if a misfire of cylinder #3 is observed following a 10 to 20 minute hot soak, perform the Repair Procedure.

Parts required:
56028371AA Ignition Wire Shield

Repair procedure:
1. Cut insulator sleeve, p/n 56028371AA, to make two (2) insulator sleeves
about 25-30 mm (1 in.) in length.
2. Install one sleeve around injector #3, with the slit on the upward facing
side of the injector. Install the other sleeve with the slit on the downward
facing side of the injector.
3. Confirm sleeve is flush to intake manifold surface around injector.
4. Check injector #3 wire and ensure that the injector is rotated to a 2
o'clock position (from driver's side of vehicle).

Thumbs down My turn signals are messed up!

I have a 2000 jeep cherokee, both of my turn signals have been slowly going out over the past 6 mo and have finally died. It sounds like it could be a short but i'm not sure. Whats weird is that my hazards work fine. I replaced the fuse and still nothings changed.

Plz help!

Fuel pump.

Hes only asking $700 for it because of this issue. Any suggestions of what this is?

Thanks for the help. By the way im a noob here. However ive been creeping for months, just never posted up. DOn't have anything to show....

Sounds like heavily worn track bar bushings... have someone steer the jeep while you look underneath what is bad..cheap fix.

Engne hot, measure the sensor output volrage, should be something between 0 and 1 volt. There are three wires, one is a ground; the other is +12 for the heater and the third is signal so you can't go wrong.
