#4738 of 5143 Re: 2000 Jeep Grand Cherokee Limited Quad AWD front end noise whine howl. [dan7jeepman]
Apr 08, 2010 (7:12 am)
I had the same problem on my 1999 4wd GC.You are hearing noise from the front hub bearings. Mine started getting noisy at 135,000 miles. The recommended method to check them (jacking up and pulling sideways on the wheel to check for play) did not indicate they were bad. But, I suspected them anyway because whenever I would spin a front wheel by hand, I could hear the noise (same pitch, but not as loud).
I put the best bearing assemblies I could afford on it (Timken, purchased through Autozone around $80 each side), and the noise completely went away! For these hearings, you buy the whole assembly, not just wheel bearing like on a car. These assemblies are very strong.
When I removed the old bearing assemblies, they still had grease in them and still turned freely, but I could feel needle-spaced racheting on the left one when turning then slowly by hand. So that was the problem. Always replace them in pairs. Good luck with your Jeep.

Hi guys, I need help with my 4.0 please. I'ts got 135,00 hiway miles on her. Very good shape yet. When I go out in the morning it starts first thing fine and dandy[ If the battery's not dead, just replaced it but it still drains], But when I stop somewheres and come back out it starts but runs very rough, like it's not running on all cylinders. If I drive it a block, it settles down and runs fine. It seems to need to be driven a block to sort itself out, it won't settle down just sitting and running.
I tried some tune-up things- plugs, wires, fuel filter- runs the same. This problem is not consistent, it's not every restart.
Thanx for any help--Bob

Get the Haynes manual and do all the emission control checks. Check for vacuum leaks. In addition, something may be draining your battery overnight and/or alternator output may be inadequate. Vehicle should run off the alternator, but if it cannot provide enough current, engine will draw from the battery.

Thanx for your reply. In reply to the emission control part, what item would cause the jeep to start like it's running on 3 cylinders, yet run perfect after 1 block? I believe I wrote that in the post.

I have a 2000 Jeep Grand Cherokee Limited 4.7 . I have recently had the motor rebuilt. and they tell me, my pre cat and aft cat are plugged. It is very expense for these. I also live in San Diego, Ca. So, the dealer is the one that carry the cats. I need other place or someone who can sell me there used ( but good ) Catalytic Converter. I have found after market cheaper. But they won't ship to California even if they are OB-II. Can anyone help me.

Yes, I am interested as well. This happens in my 2000 JGC occasionally, especially when it is warm. Cold starts don't have the issue most of the time.

cali emissions control board are the strictyest inth land,
lived in lala land for 8 yrs,and-no-NOBODY will sell you used cat converters..it's illegal,plus,the platinum in those makes th resale value utrageous..
my best sugestion..
first,is th exhaust on th car> if they're off,take a soft-brass HAMMER,and knock th crap out of them.. i found a old ford aerostar i got way cheap..would start,but when you'd try to accelerate-even in park,it'd die.. went to the exhaust pipe,and listened--it was TOO quiet.. figured it was kinda like "th bananna in th tailpipe" syndrome,where in fact-=like most american drivers-they "baby" their cars,and seldom clear out th exhaust-by "kicking it in th butt"every now and then..add to that,the cheap CRAP they sell us for gasoline,and the converter gets plugged..out of shear desperation,i climbed under it,and took my 28/oz framing hammer-and tried my best to knock a hole in th converter...th metal(after th shield came off),was so soft,it wouldn't make a hole..ten minutes of really hitting it,i gave up-for then..just to try it,went and started it up..a HUMONGUS cloud of coal black smoke came out th tailpipe,and that van never ran better!!...i did give it a new o2 sensor,but drove that truck till th wheels fell off-for over five yerars !
you might want to try knocking th crap loose,maybe put a new muffler,as those are only $50 buks or so,some new o2 sensors,and give THAT a try !
#4745 of 5143 99 Grand Cherokee won't turn over
Apr 19, 2010 (8:53 pm)
Hi, I've recently had trouble starting my Jeep, as soon as I put the key in the ignition all the gauges come on as normal and so do all the lights and all other minor electronics but when I turn the key absolutely nothing happens, the jeep doesn't even try to turn over, someone mentioned that a key gauge is supposed to light up when the key is inserted but I haven't seen one light up.
These are the things I've already checked out.
-Jump started the jeep with no luck
-Checked the starter fuse
-I've also bridged the starter with a screwdriver which worked for a day but since then I've tried doing the same thing but it doesn't work.
Any help would be great. Oh yea ever since I've had the jeep there are times that I have to push the gear shift in park a little more and it would start up right away, but that won't work either.

Try ebay motors. I've been buying a lot of parts there. I've seen new converters for sale. If you find one and it's not an oem fit, see if a muffler shop can make an adapter. You probably could use a new muffler or brakes. Ask them to install new cats as part of a pkg.
I don't know what kind of reception you are going to get if you ask them just to install your new cats
#4747 of 5143 Starting then running rough???
Apr 29, 2010 (6:54 am)
I have replaced the battery, alternator and belts...Each morning the Jeep will crank, but will not start until I hit the gas pedal. Once it gets going, it will not idle so I have to keep the gas and break pedal held to shift into gear, which at this time still has a hard time going. The weird thing is when the Jeep is driven somewhat, it will start the next time throughout the day no problem??? I only have this problem in the mornings, but it seems to be getting worse. Has anyone else had this problem and if so how did you remedy this situation??? Please advise!
