Dodge Duramax
As Ford bought Cummings some time ago. I had heard that Ford was going to use the Cummings. I have seen nothing in writing.

Dodge Duramax
I have the 2000 Dodge 3500 quad cab. I drove the Dodge and a Ford crew cab back to back at the time I bought it. The dealer was Ford, Dodge and GM.
The Cummins definately has more clatter on the out side but I liked the noise better on the inside. I went with the Dodge mainly due to the fact I did not want the old twin I beam for the road. If I was buying four wheel drive I would have gone for the Ford as it was the better deal, option for option.
If you are buying a large truck for pulling why are you considering an automatic? Part of the advantage of the diesel is the brake horse power in the motor. I would not be without it for hills.
I personally would not go for a Duramax. I guess I am like the semi owner, I am not going to invest in an unproven motor, especially in a company with GM's track record.
Would I pay 3800 extra for the risk?
Here the 3-4 year old GMC and Chev Diesels are about 4 K to 5 K less than the Dodge or Ford.Where is the value?

All I can say is I have 2 year old 3500 Ram with the Cummings and it has never been in the shop for repair. I have not had any recalls. I have the heavy duty rear end in the truck, but as the earlier post state the torque of the cummings will tear things up.
My previous truck a 97 Ford was relatively good, but had a few recalls and I had to rip apart the rear end before 60K to replace a 2 dollar outer end seal.
I would believe that if you can not keep the rear end in the Dodge that there something else wrong with the truck.
Like doctors these days mechanics are a little short on diagonsis and logical thought. Any difficult problem I have had with a car I have had to diagnose myself. Keep at them till they get it right.

Keith;
All brands have problems and defects from the factory. Unfortunately, with the complexity of cars these days, few people, are capable of diagnosis.
For example, I have a old Volvo on which we are the second owners. Once we bought the thing at ~ 100,000 miles a sharp right turn will give a bang once in a while. I suspected a lower right ball joint. Checked it and found slight play in only one axis. Not common for wear related failure.
In going through the service repair, I found that the previous owner had problems keeping the tires in balance and aligned. Symptoms of the problem persisted back to 30,000 miles or less. She had taken it in numberous times.The dealer is a larger dealer in AL with professional staff and also has the MB dealership at the same location.
The jist of what I am trying to say is it does not matter the dollar value of the car the odd defect will escape detection, and despite the best mechanics training they may not be able to spot it. As they say physician heal thy self.
Unfortunately, it is much worse when the physician is the diagnostician. To think Holmes was patterned after a physician.

Well if we want to get into it, I have a couple of Toyota stories to tell, so I don't think anyone is beyond reproach. As I know the Volvo well I have stuck with the Volvos. Not too much to relearn on a new car. Unfortunately the newer ones are all front wheel drive so, I will be looking for a new brand.

Keith;
If you still have the truck, provide us with the details of the problem, repairs and current problem. We can see if our collective minds can traack down the real root cause.
Maybe you can start a new post under Dodge - Dogs etc.

OK Keith lets get started.
1) What engine in the truck? Is it manual trans?
2) What was repaired in the first instance, shortly after you got the truck? The rear end? Did they replace the rear end or only the guts?
3) On the second repair did they replace the rear end or only the guts?

The only thing that appears to be common to the failures is the rear end housing. Todd may have struck the nail on the head in his first post.
I would suspect that the casing is machined or cast incorrectly. They kept replacing the guts but the wear is caused by the incorrect alignment of the shafts. Todd?
The only other thing would be an out of balance drive shaft but I think the U-joints would go first and that would not explain the first occurance.

It is definately in the geometry of the crown an pinion gears, but it is difficult to know what it is. It seems funny that they have assembled it twice and not had any tell tail binding . I would assume that the casting is placed in a boring machine an all three surfaces are drilled and bore at once. The machine set up must be wrong to get it incorrect or the casting was not filled correctly so that a mounting point was incorrect.
To see the type of failure you are experiencing the pinion gear must be contacting the crown gear incorrectly. I think the pinion shaft would need to be at the wrong angle to the crown. If the input shaft were high or low you would have difficulty assembling the rear end. Could could get the same effect it the propeller shaft are missaligned in the housing but the method of manufacture would still allow the proper centering of the bores with the input pinion bore.
Again this is likely a Dana problem and the rear end should be returned to Dana for analysis of what went wrong in the manufacturing technique.
