To say nothing has gone wrong would be a lie, but the few that have were not that bad.
When I first bought the truck it was well neglected as far as regular maintenance, but otherwise very solid.
All it needed was new belts, hoses, brake kits, complete fluid changes, a few light bulbs, and new tires.
At 150,000 I replaced the universal on the drive shaft.
At about 170,000 the front end / steering components had to be replaced due to normal wear.
Minor rusting on the rocker panels and in the bed, but not bad for a vehicle in New England.
The Cummins turbo in this truck is an unstoppable power house, if only it were a manual with 4WD.
Outside of general maintenance the hardest thing I had to do was adjust the valve clearance and lash. It took me almost six hours to get it right.
The fuel economy of the diesel is worth the price at the pump, $1.51 per gallon, but 600 to 800 miles on a 22 gallon fill up is all right with me. That exceeds factory numbers by a decent margin.
I have a 1991 Dodge diesel pickup truck. Great truck!!!
It has a lot of power, but the best fuel mileage I have gotten was 21 mpg. How did yours get 27?
Last night my front right wheel nearly fell off while I was backing out of my driveway. How lucky I was that I was not going fast. The swing arm just broke into two. An hour later, and a skillful tow truck driver, the truck was moved and the street unblocked. I noticed that at 170K you had the steering replaced. Is this recommended, common? My 1991 D250 has just about that many miles.
I recently bought a 1991 dodge diesel, 4x4, 5spd, with new rims cnc'd by nitro. The guy also put a 4 inch exhaust system with no muffler. It's extremely loud and suprisingly quick. So quick that even my mom in her 2004 6 liter was surprised. Granted everything that can be done has. The ford now has 675hp, and 894 fpt its pretty ridiculous. But I'm just puting in my comment to encourage people to take there old diesels and PUMP THEM UP. They will surprise you I promise, and at the moment I'm trying to put together the club SACTO TORQUE together, but it will probably never work. thanks.
I have a 91 with 210,000 miles. Max mpg is 23.5 with 2wd, 5 speed. I also had a 93 350 DRW with same specs and got 21 mpg with that truck. No offense, but 27 mpg??? I did lower control arms @ 200,000 miles. Engine still runs like new. I used to think this truck was powerful until driving these new electronic motors with over 300 hp and 600 ft/lbs. When towing a heavy trailer (over 10,000 lbs), I wish it had an extra gear between 3rd & 4th. Or perhaps a 2 speed rear would help. No rust on mine. People always ask what year it is. Looks like new.
I'm worried about my 91 Ram diesel automatic transmission with overdrive. I've heard some horror stories. Any comments on how to protect my trannie?
I have a 1991 dodge cummins the guy I bought it from put a banks stinger kit in it and for a short while stood at my house while there I had him turn up my injector pump up a little and I pulled the mluffler it now has 250+ hp and about 560+- tq just sayn turn up your older diesel youll love it.
I recently purchased a 1991 dodge d250 with the cummins and let me tell you these are the best diesel on the market for the age and mileage. I would recommend them to anyone. This truck runs like new and has over 260,000 miles on it and still gets 22.5 mpg.
October 19, 2007 I own a 1993 and a 1991 1ton and a 3/4 ton dodge with a cummins. I get around 23-25 mpg. I have a bosch fuel pump with the marine injectors. It is a monster if you need it to be. It is nice to own a real truck and not a grocery getter. Is there anyone else who has the marine injectors? What say you?
OK so I am curious how you get 27 mpg???
I have a 1991 5spd and am running it stock, and am getting 22mpg... does Banks make anything for a 91, and what's the best way to turn it up?
Does anyone know where I can get parts for a 91 Dodge diesel?
I have a 1991 2wd Dodge with the Cummins. It doesn't have an OD trans, but it does have 308 gears. It also has 224,000 miles.
I changed the turbo housing to a 14cm, removed the muffler and put Ex. to rear with only 3", and installed a K&N air filter and it runs 25-26mpg if I say under 60mph. And 26-28mpg if I use biodiesel. It will still pull a big trailer, but the auto trans is not that great, but it will still get 17-18mpg when pulling the trailer. Motor is the best thing about the truck.
Also, do not lean against the body; it will dent very easy.
My 91 D-250 has a 5.9 gas with O.D. trans. She's not the prettiest but is unstoppable. 302,873 miles.
Original engine, trans rebuilt at 215,000. Gooseneck & Fifth wheel and bumper pull hitches. 4:10 Dana 60 out of a 76 Power Wagon.
I call her Timex. Takes a lickin keeps on Tickin.
Shes even been down the 1/4 mile at an amazing 14.2 with 290,000 miles!
Hail Mopar!
