2005 Dakota 4.7 harmonic vibration by mladanye
Jan 26, 2008 (6:29 am)

I have a 2005 Dakota 2WD Quad Cab 5-speed automatic with a 4.7. I bought it new. After owning it 1500 miles or so, I noticed a vibration through the cab, very strong, at 72 mph in overdrive, and 59 mph w/ overdrive off, both at 2200rpm. I brought it to my selling dealer, who agreed that the noise and vibration did not feel normal. Their technician, over the next two months of service visits, replaced the flexplate, torque converter, short block (they said maybe the crankshaft was machined improperly), harmonic balancer, driveshaft, complete exhaust system, and three of the four tires. A lot of wasted warranty time and parts, as it still has EXACTLY the same noise and vibration at the same speeds. It does not do it at idle - I have to be driving at road speed, and the vibration is stronger under load, like driving up a long steady hill. Any similar complaints - ideas??

will a 1993 3.9 V6 dakota engine interchange with a 1995 3.9 V6 dakota engine? If so what all needs to be changed to make it work?

The only vibration I had with my Dak was one of the Ujoints on the rear axle wore out. It was replaced under warantee.

i'm stumped...please help by mailee75

Hi all, i'm having troubles with my dakota...it's a 94 sport, 3.9 automatic 2 wheel drive.
 
so, when i start the truck, it shimmies n shakes, if you give it gas while still in park, it has a high pitched whine that accelerates and goes down with the engine....can't figure it out....when you drive, it seems to be sluggish, like somethings holding it back, tranny seems to shift when it suppose to but hits hard and winds out a little when goin into 3rd....tranny fluide is full and doesn't look or smell burnt. we recently put on new brakes, rotors (on front), and rims with wider tires off a durango...but do not have a lift on it yet, so the tires rub a little, but they don't seem to be the problem as this is going on when the truck is in park and you give it gas.....
 
also, it's not throwing any codes....
 
 
 
any suggestions on what to try or what it could be? thanks in advance

I've recently become a Mopar enthusist since my Procharged 383 S-10 was spanked by a 95' dakota with a procharged 360. With the S-10 days left behind I purchased a 94' dakota SLT, and with all the mustangs running around un-cheked I'm ready for a possible swap from a 318 to a 360 (bad valve knock!) But everyone warns me and no-one will help! Will some one help Me put these mustangs to rest! I just need the recipe, I'll cook it.

How about this K-car? I was present to watch this happen. The crowd was laughing until the lights turned green.
 
Keep in mind that car in the other lane is a REAR DRIVE Toyota Supra with a turbocharged, twin-rotor Mazda engine.
 
That K-car is 4-cylinder FWD WITHOUT nitrous and it can blow away hondas, mustangs and most any other car. It is inexpensive to make those K-cars go fast. (just add turbocharger)

i forgot you will also need a harmonic ballecer the 360 is externaly balleced allso the flex plate if you use the one off your 318 you need a wait on the coverter .I just built a 93 360 but i used the stock intake do to funds .had to port the intake to match the 360 head ports .that is starving the pore girl but still runs good put stuby headers on and had custume exaust duels with hi flow converters and aero turbine mufflers igot a picture of the truck in carspace. hope to see what yougot see ya

I almost forgot! What about the motor mounts? Do I have to mess with relocating them or do I just get 360 mounts and button it up?
