The vibration that you are experiencing is not in all RAMs, only a small population. Unfortunately, if you want to completely escape the possibility of this happening again on the next truck you buy, you might consider one from GM because the newer "F" series and Superduties are having a similar problem.
There have been some reports that replacing the U-joints have resolved this issue on SOME RAMs. Others are reporting that a combination of tire and rim out-of-roundness as resolved others. There was one report here in Edmunds about a drive shaft being out of balance.
Keep the pressure on your dealer. I suspect that there may be a combination of component quality issues that is affecting some RAMs with the problem. Having a component issue in more than one area compounds the problem and makes it more difficult to troubleshoot.
Good luck,

After many hours of studying my service manual, I set up a voltmeter and tested the operation of the PCM as I drove down the road. It showed me that when the PCM sent the commands, the transmission did exactly as it was told. Unfortunately, I tried to clean the TPS and only managed to make it worse.
After replacing the TPS with a new one, I was disheartened to find the problem not only didn't improve, but got worse. Now, I knew the old TPS was bad, so I remembered reading somewhere about disconnecting the battery to reset the PCM. I disconnected the positive lead from my batteries for about 1 hour and then reconnected. Like magic, all seems well again. My transmission is shifting perfectly without a hint of malfunction. I guess you could say I did a hard reboot on my PCM and it reset all that it had shut down.
I'll keep you posted, and you can bet that regular maintenance on this transmission will be done in the future. At 265k miles, I'm happy to say that I've spent more on fuel than than this truck cost me new. Well... Maybe I'm not happy about the cost of the fuel, but I am really happy with how great a truck my '96 Dodge Cummins diesel has been and continues to be.
Also, how about safety ratings? Did that generation of Rams get as good a rating as the current generation did? Any input would be appreciated. Thanks!
The V-10 is every bit as solid of an engine as the 360 from which it was derived from. I am not aware of any maladies specific to that engine. In fact, the intake manifold gasket problem that affected earlier magnum 3.9s, 318s and 360s does not seem to be present in the V-10.
I'm not sure about the safety ratings, although I don't think Dodge RAMs stood out in this respect.
Bests,

One thing I do agree with is their rating of depreciation, which shows the RAM as better than Ford and GM variants.
Bests,
Dusty
P.S. Host, my apologies for the subject entry but unlike Dakota there is no "General Topic" category for RAM.
Actually its not that bad on gas, our 99 Ram 3500 V10 4x4 dually gets 14 mpg hwy empty and 8-10 mpg hauling a 12,000 lb trailer plus having 4000 lbs in the bed of the truck. Not too shabby if you ask me. We had a 2001 Ram 2500 V8 (5.9L 360) that was much worse on gas and couldn't get out of its own way.
Also to put it in perspective, my V8 Nissan Titan only gets about 16-17 mpg on the hwy empty and 10 mpg towing a travel trailer.

The molded plastic (currently running one in my '03 Silverado and '01 Ram diesel) are ok. The ridges are quite deep compared to a spray-in and tend to get rocks/wood chips/whatever stuck and nearly impossible to remove. The Ram has a hole cut-out for the gooseneck, and whatever you're hauling gets stuck down under the bedliner. They seem to have held-up fine, but I have no idea what it really looks like underneath. Might be a rusted mess. I like the plastic liner because you can slide stuff in/out real easy, however that's also a negative because then everything slides around and has to be tied off.
My '03 Ram diesel has the spray-in (rhino) and I'm completely satisfied with it. It's sprayed right around my gooseneck so there's nowhere for stuff to get stuck. I've used shovels in the bed hauling decorative stone, mulch, topsoil, etc. and it always cleans up just fine. Is it show-quality clean? No, but it's a work-truck. I DID NOT do the over-the-rail spray-on because I was concerned about fading and such. I put chrome caps over the side rails which makes it easier to slide stuff in/out anyway. So if the bedliner does fade I can't say that I really care. It can't look much worse than how a plastic liner looks after it's beat on for a few years. I like the fact that the spray-on is grippy and things don't slide around. But it's not as easy to slide cargo in/out either.
The rubber mat....I had this in a '95 Tacoma and it was just ok. Obviously no protection for anything but the floor. Worst thing was it would move around on you if you were trying to slide something heavy into the bed. I'm not really a fan of this, although it might be a nice addition to a plastic bedliner since it would keep stuff from sliding around. Roll it up if you wanted to slide-in heavy stuff.
As for resale value, I think the plastic dealer was blowing smoke. I've never met a truck dealer that didn't like to see a spray-in liner. I have a friend that runs a used truck dealership (big, over 100 trucks in inventory) and he says the spray-ins make for an easier sale. Lots of people lift-up the plastic liners and don't like what they see. I've personally never seen one with the mat/padding your guy is talking about.
IMHO, price talks. If you like the plastic features and it's cheap, go for it. I didn't spray my Silverado because for what I use that truck for (very light duty) it's more than adequate and I don't want to spend any $$ on it. It came with the bedliner and I don't plan to keep the truck very long anyway. If you have to buy liner and the plastic is even close to the spray-on then I'd go spray-on without a second thought.
Retail value definitely does not drop with a spray-in liner.
The spray-in liner can fade if it's a color, and the black can turn grey. The seems to affect Rhino more than Line-X. Both are easy to clean. Just hose them out. They are different products with different finishes, you should check them both out.
The only downside for me, is that a spray-in is more expensive than a drop-in.
drop in's are cheeper but do rust the bed and collect dirt. Also cargo slides.
bed rugs are great if you have a shell and are only going to carry small stuff. Used kinda like the trunk of your car.
Spray in's scuff only the paint for adhersion. I would suggest to go with only the under the lip option and get a cap for the edges.
There are so many different brands out there that would make your head swim. Shop around and make them compete for you! Even the lesser known brands have excellent products. Pick one that has the texture you want and a warrantee that will let you bring it back if it gets scratched bad.
As for resale/trade in's.
The local dealers will pull out and throw away drop in's and bed rugs on trade in's.
This bulletin involves erasing and reprogramming the Cummins ECM with new software.
Symptom/Condition:
The following enhancements are included with this software:
Improved Fuel Economy - A new ECM calibration has been developed which should provide customers an average fuel economy improvement of approximately 1 M.P.G.
Reduces white exhaust smoke on cold start at temperatures below 50 deg. F (10 deg. C).
Improves accuracy of the fuel economy calculation in the overhead console display.
Does that help?
and the 5.6l v8 cummins diesel is already being marketed to anyone interested. and i mean anyone. if ford wants to buy it for the f150...then i'll bet cummins will sell it to them! might not make Dodge happy but it could certainly happen...
and the 5.6l v8 diesel is not meant to be a replacement for the I6 cummins diesels. a larger 6 something litre I6 cummins is on the way for heavy duty dodge trucks...maybe even as soon as '06.

This is the 6.7L Cummins ISB, essentially a stroked version of the current 5.9L. The 6.7 has been in use for some time in agricultural apps, so it will have plenty of "mileage" under its belt before it ever gets under the hood of a Ram. In fact, every change to the Cummins has always had a good 2 years of service in another application before Dodge uses it.

Where is it leaking from, and did it leak before? If not, it sounds like they did a poor job on the axle work.
Also, did the axle work help with the vibration, or was it just the driveshaft replacement that improved things?
Finally, the 'lemon laws' vary from state to state, so you'll need to investigate further. However, you should have been given a booklet on the lemon law for your state with your other documents at the time of purchase. The best advice until you take it further, is to fully document everything.
#1. Hesitation when cold. When I first accelerate right after start I get some hesitation. Its especially bad when its really cold or if the old girl sits a few days.
#2. A clicking/grinding noise when I turn. I spoke to the dealer and he said what I suspected that it was the U joint that was making the racket. My question is. Is that a lengthy process to replace on your own? Any special tools required?
Any advice would be greatly appreciated.
Your fuel mileage sounds great to me, and anyway, higher octane has no relationship to higher mpg.
I just took my truck in to have the TSB 18-037-04 done for better fuel mileage and to make the overhead mileage calculator more accurate.
While I was there I was just under 15k miles and they told me that I should have them change my fuel filter for $110.00. Needless to say I told him I would be able to take care of it on my own, he then proceeded to tell me that he has seen people have their trucks towed in after trying to change it on their own because they could not get the truck started. I told him that I would take my chances.
How often has every one else been changing their fuel filter. I just finished doing it and it only took about ten minutes and the truck started just fine.
He also told me that I should have them clean my injectors every 30k miles and that cost about $150.00. I run Stanadyne performance formula with every fill up for the lubrication and have never heard of having injectors on a diesel cleaned.
Thanks for your input.

This is my first post on here and I just wanted to see if anyone is having the same problems I am. I have a 2004 Dodge Ram 1500 with the towing package it has a 3.7L engine. When I cruise at about 47 to 50 mph the rpms will drop to about 1400 and then when I give it just a little gas ( not enough to kick it up into overdrive) the truck hesitates real bad. Almost like taking a 5 speed manual transmission and go 25 mph and put it in 5th gear and try and accelerate. I heard from my personal mechanic that this is a torque converter problem. I took it to my dealer twice and then a different dealer again and they both told me to bad that is the way the truck is. They said the engine is way too small for that truck. I find this hard to beleive as it has a towing cap. of 5000 lbs.
Any help on this?
Thanks Alan
My usage will be primarily commuting with mainly highway miles. Occassional towing of a small 18' boat. Occassional off road.
Here are my questions if anyone can help:
1. I'm leaning towards the std 4.7L for the lower price and better fuel mileage. Is the cost savings and mileage enough to get the Hemi? I had a 97 dodge with the 318 and it was significantly underpowered compared to the 98 Z71 I owned afterwards. I'm concerned about the cost of the Hemi and potential fuel costs, but if there are valid reasons for considering it, then I'd like to know.
2. Is a limited slip differential recommended, and if so, is a 3.55 or 3.92 rear axle recommended? Do the rear axle and limited slip differential go together?
3. Is the new full time 4WD worth the investment, and is it proven, or should I stick with the standard part time 4WD. As I understand it, the new full time 4WD provides 48% of the power to the front tires and 52% to the rear tire. You can still lock it in to 4H or 4L via dash switch if needed. My thougths were that with mainly highway miles, a lot of the newer cars come with AWD, which I was told is the same as full time 4WD, so the better traction and handling seem like a benefit. Maybe not worth the cost, or will sacrifice fuel economy?
4. Lastly, I've just read about the vibrations people have been having at highway speeds with some of the new trucks. Are the vibrations limited to the 2500 series, or a particular engine (Cummins or Hemi), and should I put a purchase off until this problem is corrected if its across the board on all new Dodge Rams?
Sorry for the long email, but hopefully there are others with experience in these areas or who have the same questions.

Do you need a 4 wheel drive? Probably not! If you feel you need 4 wheel drive the part time system is cheaper and has less electronics to worry about.
If you buy the truck with anything but the standard size tires it will require the 3.92 ratio rear end. Limited slip is a good investment anytime in my opinion regardless of 2 of 4 wheel drive.
The 4.7 in a 4 wheel truck would probably feel underpowered but would still work. The mileage savings would probably be 1-3mpg better than the Hemi in any type driving. Probably better if you bought the 4.7 with the 6 speed manual. On the occasional times you pulled a boat the 6 speed would be better to hold it in a lower gear but the auto does have an overdrive lockout button.
If mileage is a concern have you considered a Dakota Quad Cab? Before my Ram I had a 2wd 2000 Quad Cab with the 4.7, 5-speed manual and the limited slip 3.55 rear end. On steady interstate driving I got 21 - 22mpg and averaged overall mid 17mpg. Rick
