Good general Dakota parts source: [www.truckaccessories4less.net/dodge.html] "I bought some really nice interior mud mats here, custom fit for $69 set of 4 + FREE shipping." --NOTE I gave some pricing & fit info in quotes.
Good swaybars: [www.hotchkis.net/] "Best fit, performance; but WAY pricier than those included in t&h package when you order truck." --NOTE the cost caveat in quotes & a comparison / alternate.
D / C order & customer status: [www.cs.fredonia.edu/~stei0302/www/DAKOTA/order_status.html] "Mmmm, I saw this somewhere in the regular Topics & thought I'd add it here..." --NOTE I didn't know where I saw it or who wrote it; otherwise try to give credit where it's due.
Early article on Dakota Quad at: [www.trucktrend.com/feb99/la/dakota/dakota_f.html]
--NOTE a simple URL, no explanation necessary.
Great club site: [www.autoerotica_globules.com] "Way boss chic site!" --NOTE the bogus site, which should (and WILL) be immediately BOOTED from this area if anyone sticks something like this in here.
FAQ - What is the yellow goop in the oil filler tube, will it hurt my engine and how do I get rid of it once and for all (if I can do it myself)?
RESPONSE: It's sulfur from the conventional oil 'cooking' and foaming out. It won't hurt your engine. Use a good synthetic with proper viscosity / weight for your climate. Plus, use good filters. --NOTE I wrote this response some months ago but someone else wrote about the lid 'sticking' due to plastic failure of the lid. I wouldn't 'jump' on that since maybe I didn't remember the whole fix (or maybe the poster), and would simply wait for her / him to post & continue the FAQ for this very important item. This keeps the accuracy up.
--If, say one of these is wrong or changed, then another member of our tribe would politely post an update, and I would (since I was the author of it) 'scribble or hide' this post and re-post the corrected stuff... An add-on to, say the proper viscosities for particular climates & temps would be another FAQ. This, then becomes a self-policing area that should always have some very accurate data in it. If members leave and don't update errors or whatever, well that's where I believe, a_j and I come in to 'modify' certain responses with Bonnie's help & spiritual guidance. The 'spreadsheets' will come from efforts like this...
***ABOVE ARE EXAMPLES, FOR ENTERTAINMENT PURPOSES ONLY. CORRECTED ONES WILL BE POSTED LATER, AND I WILL PROBABLY 'HIDE' THIS WHOLE SCRIPT.*** :-)
With that in mind I will attempt to put some posts here over the next day or so relating to some of the questions that I have been regularly asked over the many months that I have been around.
It will start off deliberately basic and I make no apology for that - I want this to be accessible to everyone, not just those of us that have already learned our stuff.
Apologies if it turns into a 'lectures I have given' series over the next couple of days.
What does all this mean? Well it means that the 3.55 rear end (which is actually bigger in technical speak than the 3.92) requires less engine revolutions than the 3.92 to travel at the same speed (assuming that the gear is the same). The result of this is that the 3.55 will be more fuel efficient than the 3.92.
On the other hand the 3.92 allows for faster acceleration, especially from a standing start, because the engine is revving higher, and therefore is higher up the horsepower, and more relevantly, torque curves.
The 3.92 rear end also allows for a significantly greater towing capacity than is available with the 3.55.
What impact does tire size have? Well, technically none. The rear end ratio relates to the axle speed compared to the driveshaft speed so the ratio is unaffected by tire sizes. What does change is the effective ratio.
Larger tires mean that the truck will travel further for every rotation of the axle - because the larger the tire the greater the circumference. This means that a 3.92 equipped truck with larger tires can get similar gas mileage to a 3.55 equipped truck with standard tires, and still retain the performance advantage. Other factors will affect mileage - tire width and increased drag for example, but tire size should be considered when deciding on the rear end for your truck.
Imagine a situation where the right hand side of the truck is off the road, say on a shoulder, and the left hand side is on the road. The road has been salted, but the shoulder hasn't and is covered in ice.
A truck without LSD isn't going very far - a 2wd will have all of the power directed to the rear wheel that is slipping (the right hand one), a 4wd will be no better, again power will be directed to the right side of the vehicle.
However a limited slip differential will force the left rear wheel to rotate. Once the right rear wheel is spinning the limited slip differential will be bought into play, and will not allow the right hand wheel to spin freely, rather it restricts the rotation relative to the left hand side (for example the left hand wheel has to rotate once for every 4 rotations of the right hand wheel - this isn't the exact ratio, but serves as an example).
The effect of this is that power is directed to a wheel that has traction and the vehicle can move.
As with any system, LSD is not a golden tool that will solve any problems that arise, it must be used sensibly, and power must be applied gradually, as any responsible driver will be doing in marginal driving conditions.
Excessive acceleration in a situation that requires the limited slip to operate, especially if the vehicle is not moving in a straight line, can cause the vehicle to spin.
Well, the full time system is computer controlled - essentially the computer is constantly monitoring the wheels for slippage and will divert power as needed to try and provide additional traction. By contrast the part time system is manually engaged by the driver, either by way of a floor mounted shifter or a dash mounted dial (2001 models).
Whilst the full time system can react immediately, and certainly faster than a driver, the down side is that the system is engaged all the time. This means greater tire wear, higher fuel consumption and an increased likelihood of corrective maintenance on the 4wd system, as well as a higher cost of entry.
Arguments have also been made that the part time system promotes safer driving as the driver needs to be concious of the road conditions and shift into 4wd rather than rely on the truck to do it for them. The flip side of course, is that if a driver considers 2wd to be sufficient for the conditions, he or she can get themselves into more trouble than with a full time system.
What is a K&N filter and how can it help me?
K&N is a company that makes air filters. They are wll known for two things - an ability to make filters that allow more air into the engine, and filters that don't need to be replaced, ever (well for a million miles anyway). Best of all it is the same filter.
OK, some details. K&N have two main products for different vehicles, a replacement filter, or a replacement air flow system. The first is a straight replacement for the stock air filter, the second involves replacing the stock air filter with a different style of filter (usually conical) and some ducting. As you might expect the second option is more effective and more expensive.
The whole purpose of this is to get more, and to some degree cooler, air into the engine. Without getting into all of the technical issues, if this can be done the engine can generate more horse power (somewhere in the 8-14hp range), better fuel efficiency, or (with judicious driving) both.
The million mile part comes from the way that the filter is made. Most paper filters quickly become dirty and blocked and therefore less efficient. They are throw away parts and so are replaced with new filters. K&N uses a different approach - when their filters get dirty you simply clean them and replace them. K&N sell special cleaning agents and an oil that is used to coat the filter. For most people the cleaning process is a once a year thing.
#92 of 92: k&n filters (johnboy9 <<A HREF="http://townhall.edmunds.com/cgi-bin/townhall/vprofile?user=johnboy9">http://townhall.edmunds.com/cgi-bin/townhall/vprofile?user=johnboy9>) Thu 17 Feb '00 (08:34 AM)
I understand k&n filter #33-2084 will fit the 4.7 . It is for a Dodge 5.2/5.9 engine . The cheapest I found was at Auto Zone for $45.00 Johnboy9
#94 of 95: k&n filter for 4.7 (keg3 <<A HREF="http://townhall.edmunds.com/cgi-bin/townhall/vprofile?user=keg3">http://townhall.edmunds.com/cgi-bin/townhall/vprofile?user=keg3>) Wed 23 Feb '00 (09:31 AM)
got the k&n in (#33-2084). fits fine (even though its spec 'd for the 99 5.2). dont notice too much difference in the way of low end torque, there might be some increase,i havent really had the chance to test that area of it, but there is definately an increase in power at higher rpms while on the highway. its doing what it should. go get one.
Hope that this helps;

Blame it on the computers. The 4.7 has a very complicated Engine Management System controlled by computers. These computers are programmed to
try and minimize emissions and maximize fuel
economy - and they are really quite good at it -
until someone comes along and starts driving the
truck.
The computers have to 'learn' your individual
driving habits - where do you shift, how do you use the clutch when decelerating, how heavy is your right foot, etc, etc.
The computer can then adjust the way that it
controls the engine revs based on your individual
driving style. However this takes time, and for
the first couple of thousand miles the computer
will make mistakes as it encounters new driving
situations.
The learning process will take longer with
standards than automatics as there is less
consistency over gear shifts, and it will take
longer if two or more drivers aredriving the truck
for prolonged periods - because everyone has
different driving styles.
As the 4.7s move on to second owners, expect to
see a re-learning process as the computer gets used to its 'new' driver.
I'm new around here, so please bear with me.
I own a 00' Quad Cab 4.7 V8 SLT, loaded, 3.55 rear, handling pkg. ect... My question is this..
Has anyone figured out how to override the top speed limiter (97mph) or is this something that all 4.7liter owners are gonna have to put up with?
Any information from anyone would be of help.
By the way, I LOVE MY TRUCK....just want a little more on the top end!
My cruise control didn't set at that speed either.
When I first had it, the engine was slow to fire.
The dealer replaced the fuel pump module and some
check valves from a TSB. No problems for 110K
miles. Then the fuel float sending unit failed.
I had that replaced. Then, for the past few months I have noticed that when the fuel level drops below 1/2 tank it begins to bog down and miss. It gets worse as the level gets lower. When I fill up, the performance returns to normal. I took it to a Dodge dealer; they did the $65 diagnostics test and told me I need new plug wires and clean the throttle body. Before taking it in I had replaced the plugs, distributor cap, and rotor. I replaced the plug wires and cleaned the intake. No change.
I put a gage on the fuel rail and it reads 37-38
psi consistently, at idle and when driving it. I
have not done the volume check.
Should I spend the money to replace the fuel
module ($305 Mopar; $160 AutoZone) ? I've had the tank and module out to see if there were any apparent deficiencies. There weren't any. Can anyone help me?

What recommendations for minimum break-in on a new Quad Cab w/4.7, before towing a 1700 lb pop-up camper approximately 350 miles?
The Sales wiener wasn't any help. As soon as he said, "I think"...I knew I should just ignore him.
Anyway, he told me personally, he thought 2500 miles so you could do that first oil change and get the "chips" out of the engine. I said, "WHAT chips!?!" He was referring to metal chips in the engine from manufacture. I hope to heck Dodge has better quality control than that!!! This is where you visualize me eyes rolling.
Car Salesmen say the darnest things... Hey, that gives me an idea. Maybe a thread to post
Thanks,

down, and do not try to make the engine lug by keeping the vehicle in the overdrive mode, auto or manual. That is my personal opinion. Of course there are guys such as towcrazy2 who can offer advice far more profound than mine.
Bookitty
good luck all,
robert
If your observations are truly correct, there is ONLY one course of action. The problem is related to the fuel delivery system, NOT plug wires or plugs.
I would also suggest a close scrutiny of all fuel lines / hoses. A plugged vent MAY cause a vacuum in the fuel tank under some conditions. Do not forget to check the "Evap. Emmisions System" which controls the venting of the gas tank.
Lets not forget that Dodge is KNOWN to have fuel-pump problems in their trucks. (I beleive that the same "fuel module" is used across much of the Dodge truck lines.)
Have you actually monitord the fuel pressure WHILE THE ENGINE WAS MISFIRING?
thanks for the info on towing. I don't think I'll have any problem as I've put on over 1000 miles in the last two weeks. Whoa...better slow that down! Also, I have the 4.7/auto so I'll watch for lugging and be sure to switch it out of O/D if the transmission is searching for the right gear too often. That's pretty much what the manual says.
towcrazy - any thoughts???
Wow, this Quad is sure comfortable for a long haul. Went over 300 miles today and averaged 20.3 mpg @ 55 - 70 mph. All without getting a backache. That's more than I can say for my (ex)Explorer...

Anyone know what the Fram Oil Filter # would be for an 01 4.7? Looking in the July 2000 Fram book, it appears that the TG-16 is used for most Dodge trucks (as well as my wife's '97 LHS), so I pickled a couple up. Could this be the Chrysler standard?
I'd prefer an answer before I remove the existing filter. It would really suck if I had to put the old filter on with new oil.... :-( Anyone?

I've never even seen a Mobil 1 filter around here (Madison, WI). Maybe I'm not looking in the right place??? Where have you found them?
I'm using Mobil 1 oil and Fram filters in all my vehicles. Is there some data available to substantiate your fear of Fram or just personal preference? I usually use the "Tough Guard" series so it's not bottom of the line, so to speak.
Thanks as always for any and all feedback!

Iowabigguy, I believe I also heard that the Mopar oil filters are just Frams that they put their name on.

I own a 00' Quad Cab 4.7 and all the good stuff!
I was wondering if anyone has any idea how to hard wire an radar detector? Oh, and on a side note, I love this truck!!
Thank you to anyone who can help
I hardwired my Valentine detector as soon as I got my truck. Take off the A-pillar cover (take the screws out on the driver-assist handle). Then you can drop your wire down that corner of the dash and find a good power supply. I tucked the wire above the headliner over toward the rear view mirror and just clipped my detector on the edge of the headliner.
Doesn't seem to be one in the 2000's and there are no 2001's on the lot here yet.
Thanks for your help!
Just wondered if anyone checked any rules or regulations about this type of thing.
Bookitty
good question, first time ive seen that one on here

It is known to be inefficient and it actually is rated with WORSE MPG than the 4.7L V8 HEMI which is perhaps the smoothest engine I have ever encountered.
You asked for thoughts/suggestions...
Ask to test drive some other similarly - equipped rigs on the dealers lot. Try to ascertain if your rig is unusual or "normal" as the dealer would have you believe.
I have heard of a mis-firing injector causing the V6 to be rougher than it should be. I read it in one of the Edmunds forums recently.
Good luck...
However, I will keep an eye on this and report back.
Anyway, I did drive the truck before buying, but that's exactly what I did, was DRIVE it. Not much time at idle on the test drive. It's extremely annoying. I'll give the additive a shot, but the truck only has 2800 miles now. It shouldn'\t be anything like that. I'm still open for suggestions/similar experiences.....Thanks folks...
As far as heater cores go, they seem to be streaky. on the DML (www.dakota-truck.net) a couple of members have had real problems with the cores, losing 2 or 3 in the truck's life so far. The concensus has been that the plastic cores are not reinstalled carefully. If it gives you problems afterward, discuss an aluminum core and see if your dealer will go for it. It's a HUGE pain in the rear to swap a core, and they might be willing to put in an aluminum unit to get you out of their hair after one or two fudged installs.
BTW, check out the DML, it's a wonderful resource and a lot of fun
