#4551 of 4608 1999 Jeep Grand Cherokee Knocking... by 5moremiles Sep 23, 2009 (9:19 pm)
I have a 4.7 that was knocking at 2000+ RPMs, was told to replace main bearings, I did so, the main bearings had no sign of wear, however as i Rotated the crank during removal of the first bearing, both of the thrust bearings fell out, upon visual inspection, both thrust bearings have signs of wear and metal gouging. Is this my problem, and what is a thrust bearing in an engine for? Replies to this message: loosenut (Sep 23, 2009 9:55 pm)

Replying to: mr_smith (Sep 22, 2009 6:49 pm) I don't know about the 2006, but my 99 was doing that, and after going through throttle body, fuel filter, and tune up, I was told to replace camshaft sensor, I did with great success, did the job!

Replying to: 5moremiles (Sep 23, 2009 9:19 pm) -a thrust bearing-ifin i demember korectlee(sorry,my poor attempt at humor),-ANYWAY; is to keep the crankshaft-or camshaft- from moving forward or back-front to rear,if that's the bearing i'm thinking of.. -the last time i dealt with a thrust bearing was in my -64 air cooled bug..in that motor,they had what amounted to washers that went behind the flywheel..you'd stack them in there,till the shaft only moved about .003 -thousants-cause heat expands-etc.. ---i could be wrong..also,haven't looked into how a thrust bearing sits in my jeep engine,or how to service/replace it..good luck !
#4554 of 4608 -98 gcl,5.2-dana 44 axle bearing noise. by loosenut Sep 23, 2009 (10:16 pm)
when gas hit 4 bucks,got a great deal on this old jeep.. i've fixed the broken windows(pax side 1/4 ,and front door glass),-ever since i've had it,the rear axle "whines",but hasn't gotten any louder..i think it's the pax side bearing,but-of corse-every service dept wants two grand to rebuild it,witch i feel is overkill if the only thing really wrong is that bearing.. --anyone else out there in cyberspace had a similar expierience with that series-all time-all wheel drive,aluminim casing-dana 44? -also,when changing the back parking brake-the wear pattern on the shoes was wierd,like the axle wasn't setting in the right place.. --ain't got money to waste-as this thing's only getting 12-14 m.p.g.at best,and the tank is always hungry,so i don't need to throw away money i aint got.. --anyone else had this problem?

Replying to: a72rose2 (Sep 25, 2009 6:47 am) as far as running-sounds like a plugged catylitic converter or muffler..also,try putting marathon premium in it for winter..that cheap crap that smells more like kerosene than gas is why you get to tune it up twice as often as i do --that 10/20 cents per gal doesn't add up to mutch savings when ya figure in things like that..ya get what ya pay for..bla-bla.. --seriously,try a good thorough tune up..probably hasn't been done since new..ya gots ta do th maintenence on em,or they run like--that-till they leave you walking to the next exit!!

Replying to: louieco4 (Sep 21, 2009 8:43 pm) If you have fuel and spark at the cylinders, then I would have the "timing rechecked" to see that its on spec,

Replying to: quietstorm242 (Sep 22, 2009 5:51 pm) If you have the 4.7 engine, try having the throttle body cleaned, this causes low idle and stalling, (known problem).
#4560 of 4608 Jeep Grand Cherokee 4.0L petrol straight 6 - HELP by placesinfrance Oct 02, 2009 (1:05 am)
Ok, I need some serious help!!   I have a 2003 Jeep Grand Cherokee 4.0L petrol straight 6, now I have been suffering with a loud tapping noise that I would normally say is the tappets, but this only happens when the engine is cold then gets louder then just stops when the engine warms up, the tapping does not fade away, it just stops dead!! like a switch has turned on! got to add that you do not hear this when you 1st start up, only after a few seconds (10-15) the tapping starts.   But also when the engine is warm, you can hear this tapping (not as loud) in cycles, see if i can put this in to words!! the tapping starts off softly then builds in loudness, then just stops, again like a switch has tripped, then it does this again and again!!   Have had this checked by Chrysler - !!!! no help yet!!   Can anyone HELP!
