#4035 of 4362 Front Passenger Dash Noise 2005 Dakota
Feb 06, 2006 (5:42 pm)
My 2005 Dakota has a rattle noise in the front dash on passenger side. Sounds similar to a loose screw vibrating, wobbling, snapping sound. Dealer checked outside plastic molding on bottom windshield outside on passenger side. Checked wiper blades, not the problem. Then dealer thinks it is in the windshield. They have a windshield company remove windshield and reseal it. That helped some to reduce noise, but still there off and on. Can hear it with radio on and driving 30 to 40 MPH. Gets irritating to hear this. It starts and stops on a whim or bump, not a constant rattle. Anyone else have this or a fix? Dealer asked Dodge Tech support they say they don't know any other Dakotas doing this. Dealer has had truck in their shop for 10 or 11 days total in 4 different visits.
#4036 of 4362 4.7L Ignition Noise
Feb 07, 2006 (4:27 pm)
Over the past few weeks I've noticed what sounds like an intermittent ignition noise coming through the radio on my 4.7L. I varies with engine RPM and goes away when the engine is turned off. With coil on plug ignition on the 4.7L, there aren't any plug wires to replace, so I'm at a loss where to start looking. I suppose it could be a bad plug (just replaced 3K miles ago) or coil module. Anyone have any thoughts? Thanks.

I would suspect, as you do, either a coil or a plug but also would look for a bad engine-frame ground. Did you use dielectric grease on the plug boots when you installed the plugs?

Are you hearing a "crackling" sound or more of a "whining" that increases with engine RPM?
A "whining" sound is the ALTERNATOR... not ignition.
In any case, I would recommend that you pull off each ground lug one at a time and file down to bare metal below each one. (I even soldered the wires to the lugs just to make sure corrosion would not get in the crimps.)
#4039 of 4362 Down and out on dodge dakota in Alabama
Feb 07, 2006 (5:57 pm)
I purchased a 1995 Dakota extended cab truck third owner
since bought new. after two months of daily driving I heard
a clicking noise coming from engine,but the noise did not
sound deep into engine.so I tore down front of engine to
timing chain found that the upper bolt in cam shaft which,
holds upper timimg pulley on shaft was loose.I replaced both upper and lower timing pulleys.Also replaced tensioner
also.put back together and drove for two more months without any trouble. I traded it to a friend of mine for
a full size chevy Z71.To cut to the chase since my friend
has had the truck this problem has happened twice.The last time I tore down the truck for the third time,I replaced the bolt rethreaded shaft and used red thread locker and
also used a lock washer.Problem is still happening seems
as if it wont go away.If any one has had simular problems
please HELP!!! I do not wish to end my friendship with this guy over a truck I offered to trade back but he wont
have it.Down and out!!

Yes, I have used dielectric grease on the coil boots. Also, the noise is a crackling sound, not a whining sound. When the weather warms up again, I'll check the engine grounds. It is an intermittent sound. This morning, it didn't do it. Also, when it does do it, it sounds aperiodic. So, it doesn't appear to happen everytime a particular coil/plug fires.

I'm assuming from your previous post that you hadn't noticed this noise before you changed the plugs. What is the mileage on your truck?
I agree with bpeebles about the grounding system but could still be a coil or plug, most likely a coil if that is where the problem is. A coil, if arcing intermittently, wouldn't be noticable as a dead miss in one cylinder would. Look at the engine running after dark and see if you can see any arcing. Also pull the plugs and examine them carefully and see if you see any evidence one of them is misfiring.

I have the same problem and Bro, I don't know about you but, I didn't pay for a new vehicle that shakes and wobbles! I am EXTREMELY P.O'ed.!!! I am being told that I can claim the Lemon Law which I am strongly considering unless, thay come up with a solution. The bad thing is that they have to log a certain number of complaints before they will do something about it!

After re-reading your posts, I am thinking that one of your coils may be arcing around the base near the sparkplug.
Also, perhaps the shape of the insulators on your new sparkplugs is not "sealing well" on the ends of the coils.
Pull each of the coils off and look for carbon-traces. Perhaps even hand-fit one of the sparkplugs to a coil to see how well the seal fits.
Thoroughly wipe clean the plug insulators and coils with IPA (IsoPropal Alchoal) incase there is some kind of conductive coating you cannot see.

Bpeebles, I haven't had any experience with this type of ignition system until I bought 06 Dak. Perhaps I am still stuck in the old days but don't really like the coil on plug system.
Has there been much of an issue with arcing/misifring etc?
Haven't noticed many problems posted on the forums but really curious about the system.
What has been your experience with this type ignition?
DustyK, You can weigh in on this question also.
