    Knocking noise when gas pressed. remove no 4 injector plug and goes away mostly. Just had Head skimmed, valves sorted & bedded in, newe gaskets, etc. Not made much difference

Have a 2004 jeep grand cherokee and when i push on the gas peddle it makes a knocking noise and the heater seems to have gone out at the same time


Heater 'gone out' = low coolant. Knocking noise = internal engine damage? Maybe low coolant = internal engine damage.

I hear a rattle noise while driving my 2000 jeep grand cherokee , it sounds like a loose ring , it gets louder as i press the gas any sugestions as to what this be


Check your cattalic convert inside comb have come loose if so need to replace the unit and check muffler for noise matterial from convertor may also gone into muffler but maybe its only muffler or maybe only convertor. Another posibility check A/c clutch assembly maybe is coming apart or sloppy and likes to ring bells sound like.Turn on Ac if you have if the nosie is gone then you need a clutch assembly for your AC

My manual 5 speeds only makes bearing noise when at highway speeds . repairman says it is a bearing but i thought a throw out bearing only makes noise when pushed in ,


Are you sure hes not talking about a wheel bearing for your front wheels. A throwout bearing will sometimes make nosie like a rattleing if it is not engaged. When engaged it will sound like a roaring nosie. I would check in to were this nosie is coming from first.

2006 Jeep Grand Cherokee just started making a clicking or rattling noise when starting up. The noise isn't audiable when driving. I've checked the oil level and it is normal. It is time for an oil change,...


so it goes away after a bit, that could be cause theres no oil on the top part of your engine, thats normal. wait till it gets older, it will be louder.

I have a 1999 Jeep Grand Cherokee Limited that is making a rattling/ticking noise under the hood and I cannot figure out what it is! We did an oil change and added Rislone, it quieted it some but not...


how many miles on it,sounds like lifter noise which is normal for high mileage jeeps,but if you have over 140k it is not a good idea to run synthetic oils as they are thinner than conv oil and it might start to consume oil.
