Thanks. I looked at them, and the upper ball joint appears to have a torn boot.
I'm going to have to wait until I have an assistant to try and and pinpoint it for sure.
The frustrating part is that it is an intermittent problem. I just tried driving around for half an hour to try and reproduce...
2005 Liberty Sport, 180k miles. It is in stock configuration, no lift.
When I turn the wheels to the left, I get a sort of creaking/knocking sound. It only happens when turning left, and only happens when I turn the wheels almost all the way to the left.
The noise is exactly the same whether I...
Sorry, I don't think I was clear in my post above - I replaced the spark plugs because it was idling a little rough. Changing the plugs didn't make any difference, but it wasn't really all that bad at the time.
Looking at the Autozone website, I used either Autolite Platinums or Double...
Any idea why it would suddenly throw a CEL for an evap leak at exactly the same time as it started running rough?
It seems like too much of a coincidence.
Is it possible that it is giving the wrong code for some reason?
The old plugs looked ok but were mismatched and incorrectly gapped.
I used one of those spark plug charts and I think they were fine - I just did it as a routine maintenance thing.
I also replaced the pcv valve at the same time and changed the oil.
I can't remember what plugs I put in, but I...
I'm not having much luck lately :(
Last weekend, my 2003 Liberty 3.7l started shuddering at idle and the check engine light came on.
Went straight to Autozone for a scan, and the code was for a misfire (I don't remember exactly what code it was).
Their computer recommended either spark...
I've had so many things go wrong with my Liberty in the last two weeks that I've been spending money I don't have. I don't even know how I'm paying my rent tomorrow.
It was either buy it online for $5 or pay around $20 from a parts store.
I have coolant in my trunk and I've been checking...
Correct pressure?
Uh oh, I didn't know there were different ones - I just ordered a cap for a 2003 Liberty with a 3.7l engine.
How do I know if I got the right one?
Yup, mine is definitely bad. There are a few cracks around the other seal too, so definitely time for a new one.
I'll be watching my coolant level like a hawk until Wednesday, which is when the replacement comes.
Thanks, new cap on order.
Would that explain my coolant loss, or do I have a blown head gasket?
I wouldn't be surprised considering the luck I've been having lately.
I've been having a hell of a time with my 2003 Liberty 3.7l lately.
In the last two weeks, I've replaced the belt tensioner, power steering pump, spark plugs, and I need a new fan.
Today I got a CEL for a misfire. I've replaced all the coil packs hoping that it will cure the problem...
So guess what?
IT WAS THE FAN!!!
I've spent so many hours searching for what it could be and worrying that I would need to make repairs I can't afford right now, and all this time it was just the fan kicking in.
There's definitely something wrong with the fan - there's no way it should sound...
I have a small emergency kit in my glovebox that contains a whistle.
We had all these problems with the Jeep (bad tensioner and power steering pulley, and now this mystery sound) and then we heard a rattle.
My wife was like 'What the **** is it now?!"
Turned out it was the pea in the...
That certainly makes sense, and a bad bearing in the fan motor would make a sound that appeared to be coming from the general area where I'm hearing it.
Are there any other rotating components that do not vary with engine rpm?
The AC compressor works off the drive belt - I already tried taking the belt off and the sound still happens.
This rules out the AC compressor, power steering pump, alternator, water pump, tensioner/idler pulleys as the cause of the sound.
I'm going to feel pretty dumb (but also VERY relieved) if its the fan.
I don't have a mech fan, just the standard electric one.
Does the fan come on every time you start the engine?
I was under the impression that it was temperature controlled and only came on when needed.
Are there any other...
I've been thinking about this some more, and maybe it will help if I make a list of what we know:
The sound seems to be coming from the front of the engine.
It is not caused by an accessory, because it is still present with the belt removed.
The sound starts a second or two after the engine...
Yes, it's the tuning fork type humming that I'm talking about.
Definitely not the water pump, as that was ruled out when I removed the belt.
I have replaced the spark plugs and changed the oil, but the sound was present before either of those, and has not changed since doing it.
Oil level is...
Thanks for the help so far, but I guess you would find it easier if you could actually hear the sound!
I recorded a video just now.
I'm afraid the camera on my phone is terrible in low light, but the sound is the important part.
Ignore the bang at the start, it was just me banging on the fender...
