So I settled on an 07' 1ton, 4x4, dually megacab, manual with the 6.7 Cummins. Hopefully the previous owner knew the fuel filter needed regular replacement.
Thanks for all the feedback everyone. Very helpful and appreciated
Awesome truck... should last you a long time. The manual is the kicker for me when towing, great great stuff there.
OK truck gurus, I have a 2000 Dodge Ram 2500 with a 5.9 liter Cummings engine. I have had it since 2002 and pulled a 7500# fifth wheel with it. I had the transmission rebuilt in 2007 for heavy duty towing, and they installed a heavy duty torque converter at that time along with replacing a couple of the bands . Two years ago I had to replace the fuel injector pump (v44?), a complete brake job including rotors, disks and pads. I have also replaced a couple of brake lines. It being turbo, it tows well and has been a very good truck over the years. I think though it is getting a little long in the tooth so to speak and started looking at getting a new one. The prices for a new replacement seems to be ridiculous to me, being old school and all. It appears that what I feel comfortable with price wise is about a 2010 to 2011 model, but the ones for sale seem to have 112000 and up miles on them. Mine has 128000 miles. It looks, rides and tows well. The problem at present is the wife doesn't want to trust it on long trips anymore, due to the pump going out and long story, but I had to order it myself away from home, wait for it to arrive and get installed etc. Am I pushing my luck with this one by still using it, and would I be better off up grading to a newer version?
I did that math when I allowed a wired shut wastegate that I didn't know about on an upgraded turbo (on the truck when I bought it) blow the head gasket on my '01 3500 dually.
The decision was, fix just the head gasket and bail, or take the time and money at a specialty shop (not the cheapest place per hour. But good!) to go over every nook and cranny of that truck mechanically and fix EVERYTHING (except sadly, at the time, the VP44... but the mechanic was right, you really don't know when they're going to go, and a crappy rebuild will run $2000, a good one can go as high as $4000 with options in between...)
The answer was, direct from the spreadsheet, rebuild it. Because you literally can't get a used one in any sort of known good condition at the low-ish miles mine had for anywhere near the price. And new? Unless you've got money you just HAVE to spend and want new, nope... it's a $50,000 or higher deal.
We put about $12,000 into it. Rebuilt the entire steering system with quality parts, head reworked and studded, new exhaust manifold to put the bigger turbo in a better location, rebuilt power steering pump, water pump, and new BHAF style air intake, were the biggies, and complete fluid changes and inspections on all drivetrain components, and I think we did bearings all around also. I'd have to look.
Even at that price, we still are into it, total, for half the price or less of a brand new one, depending on options and bling.
It has 120,000 miles on the engine and the mechanic said he won't see me for at least 100,000 UNLESS the VP44 fails. Well, it did... in Nebraska... and Dodge wanted $6000 just for the pump brand new... obviously we went hunting for one of the MANY rebuilders and got one from Central Nebraska Diesel, not known for being a high end rebuilder but also not known for junk... diesel trucks work hard in rural Nebraska. Out the door with labor, stuck using a dealership for the work, was about $2500.
Still cheaper than a new truck. By tens of thousands of dollars.
The vp44 requires excess fuel to cool the integrated electronic controls. When the lift pump fails it no longer gets the required cooling fuel and quickly commits suicide. There are no warning lights to let you know your lift pump quit you so a fuel pressure gauge is useful as well
That's a pretty common story, but it was an early theory that turned out, didn't completely hold up. The fuel that was thought to cool the computer and internals of the VP44 later was found not to, especially once better non-contact temperature reading devices came along. Turbo Diesel Register has a lengthy discussion about this in a very old back issue, but essentially everything in the VP44 just gets hot. No way to really stop it, especially under heavy load.
What they did find was the computers in them are definitely susceptible to heat death, and at least one company tried hard to build a "remote mount" wiring harness to move the computer off of the top of the VP44, but the timing problems, and shielding of the cables, meant its nearly impossible to do.
In the meantime, Dodge and Bosch did a little work on root cause and found that clearances inside the pump are very tight and most failures happen at a sudden request to decrease power and flow. The shaft was snapping. They figured out part of the problem was the shroud around the impeller would warp under the immense pressures inside the pump when a sudden decrease of flow was experienced, so all rebuilds and new pumps have different metallurgy in both the shroud and the spinning shaft/impeller.
The whole pump also gets extremely bursty and can destroy itself without a solid minimum of 12 PSI of flow from the lift pump, too... and that is why a lot of people believed the "fuel removes heat" theory for so long. It's really not the heat, it's pressure waves breaking things.
Unfortunately the changes made don't completely fix the problem. But fed with an aftermarket lift pump like the AirDog or FASS, and not the original in-tank pump that loves to fail slowly by lowering pressure over time, setting off a chain reaction in the VP44... the newer rebuilds with the new components tend to last a long time.
If there's one takeaway it's not to go from wide open throttle to none instantly when towing heavy and hot, but we all know people cut anything towing a trailer off, constantly.
Mine went... exactly at that point. Had to let off the throttle towing heavy on a hot day, and it started surging at the end of the off ramp... the shaft was either bent or broken and all hell was tearing loose inside the VP44, literally. It made it another mile and a half until it stopped responding to throttle altogether, truck's computer set the CEL, and shut down.
Filtration, I agree... is fairly weak on these trucks. My AirDog includes an additional filter prior to the engine filter. The previous owner trusted the AirDog filter and water separator alone, the mechanic said "not a good idea" because the engine filter also includes the fuel electric pre-heater, so he put an engine filter back on it, so I'm "double filtered" now, and have two places to trap water, which doesn't bother me at all. A slug of crappy watery fuel from a rural diesel station, will have to get by both to kill injectors.
So... I say keep it. But be ready to put some money into it at a reputable shop that knows Dodge Cummins.
The auto trans can be a minor headache also, but sounds like you did the right things on the rebuild and it'll go a while. I know one local guy who's on his third auto trans, but also above 300,000 miles and tows a lot heavier than your 7500 lbs regularly.
Here's another reason not to jump too soon to the 6.7 engine... DEF. Regeneration. Annoying emissions system whining that it wants things. Heh.
If that were mine, I would easily go for another 100k miles. Air Dog or FASS system, like noted above. If you haven't done so, a front end rebuild is looming, most likely. I upgrade my '07 2500 4x4 to 3500 tie rods, drag links, etc.
I ran my '97 2500 4x4 to 228,000 miles and the young guy who bought it is still hauling his girlfriend's horses around the country. My wife conspired with my cousin to buy his '07 because the '97 clear coat started peeling and "it's embarrassing to ride in this now"
I protested, and still do, but secretly am very pleased with the '07 2500 Laramie... bought it with 88,000 miles a couple of years ago and plan on running it to over 200k or more.
Good to hear your old beast is getting used! I still haven't met the new girl in your life. Haha.
I have a fender that the clear coat has started letting go on, and it's driving me nuts. The '01 will probably go in for a little paint work this year. I'm trying to decide how much of a country redneck I am... trucks out here often don't have paint on half the truck, and nobody minds. Heh.
