Yeh, yeh, I know it's a JK & a CRD so what do I expect. Surprised it hasn't rattled itself apart by now. :smile-new:
I have recently noticed 2 more specific rattles though which I'd like to try to diagnose before something falls off or stops working.
Noise #1
This seemed to be transmission related. I have noticed a small vibration/rattle lately when stopped in D, R, 1 or 2. It is still there in N but much less so. It seems to start a second or so after I stop, as if it's related to the transmission in some way and only rattles when the load is taken off. It doesn't happen as much when in N when presumably the transmission is essentially not connected (my mechanically inept brain's reasoning). It also seems worse when the JK warms up.
It's difficult to pin point where it's coming from as the noise is easier to hear from inside the cab. Once I get out and under the JK there are so many other noises from the CRD that it's harder to hear the specific rattle I'm chasing. It seems to be coming from the front of the JK though, which isn't a great surprise as that's where all the noisy bits are!
It's has also since been masked by another rattle that's developed more recently.
Noise #2
This is a far louder rattle coming from the front of the JK that again only seems to happen when stopped, as if whatever system it's part of is having the load released when I stop allowing it to rattle. It's is much much worse when I use the air con (as opposed to just having the fan running), but even when using the air con, it still seems to go once I pull away.
I had the JK serviced last week (not a Jeep dealer/specialist but a good mechanic) and he thought it was the air con clutch. Would that make sense? He also said that with it doing just over 90000km now that I might as well get a new belt/pulley tensioner etc as well as replace them all at the same time while it's getting done.
Being mechanically inept I have no real idea what these parts are, what they do, or where they are really. I'd be great if I could get some advice as to whether this makes sense and what parts would I need/be advised to change while I'm in there.
I think these are 2 different issues as they sound very different. #1 is gentler rattle that seems to be coming from lower down in the JK whereas #2 is much harsher and seems to come from the front of the JK.
Can anyone suggest who might be good to use to look at these and potentially do any work needed? Preferably northern Sydney. The mechanic I use for servicing is a good mechanic and is more than capable of doing the standard servicing but they won't have done any detailed work on the JK CRD motor before so once it starts getting a little more technical (which this feels like it is), I'd rather speak to someone who knows the JK's quirks. I could take it to a dealer but that sounds like an expensive (now out of warranty) and probably ultimately futile thing to do.
I'd appreciate any advice people might have. It's an MY10 JK CRD Auto if that helps.
Cheers,
Paul
