Will This Work

[Doug1810]

I found a 350 dodge not sure of the year thinkin 92 318 4x4 4. 10 gears. the int parts are better than mine. want to make my 89 a 4x4 would use this frame axles. will the tranfer case work ? i have read the trans will not i think . what about the radiator sup ? i will be makin mine i/c so would i have to buy a diesel radiator support ? he want $800 for the truck . is it a good deal ? or to much work . I will be makin the cummins 4x4 some how i just though this would be a good and easier way . Thanks

The axles and frame are both lighter on the gassers, but, it will work to swap the Cummins into as long as you are sane with the driving and power.



Transmission won't work, tcase will if it is an NP205, radiator is way to small from a 318 so use yours or a new one.



If you get it cheap, its in decent shape, and your right foot has some control it will work fine. Good luck.

Thanks . the axeles are dana 60 4500# front and 6200# rear i think . the tranfer case i did not see what it was . May be i should look for another donor truck . I use my truck not to hard but dont want to break it .

BUY IT NOW!!!!! If it has a dana 60 front(verify it), it may have a dana 70 rear too, beings its a 350!!!! At the very least, you can use the rear diff from your cummins truck. These are the same parts on a 3/4 ton diesel truck. Dunno about the t-case, it may be a 205. You'll have to id the trans and t-case.



FWIW, a dodge dana 60 front, of that vintage will part out for around $800-$1000 depending on geological area. Heck, a running 4x4 no matter what condition, or rating, is $1000-$1500 around here. I'm going out on a limb here also by saying, the radiator support may be just like the cummins trucks, again since its a 350.



Go back, and buy it.

Calm down Michael. Most likely it is a ball joint Dana 44 front. I agree if it truely is a D60F, then it's worth $800. If not, PASS. All that is good for you is interior parts. Nothing is worthwhile for diesel parts. D60 rear, pass, D44 front, pass, NP205 will work with an automatic diesel trans, not a getrag. The trans won't work with the Cummins engine, pass.



The best and easiest way to make your 89 a 4x4 is to buy another truck, already a 4x4 and diesel.

 

[Simplysmn]

Yeah what he said buy one already complete By the way I have 1 forsale thats already done complete and running just needs a new owner lol

 

[Doug1810]

I will check for the d60f . I am starting to agree with buying a 4x4 ready to go . I just thought i could save some $$$ this way But now im not sure .

All 350 Dodge 4x4's have Dana 60 fronts, the rear could be a Dana 60 or Dana 70. Only if it is a 250 should he worry about the front end, unless of course someone swaped the front for a lighter duty one. Either way check to make sure, but it should be a 60.

 

[MMiller]

Come on, he said its a 4500# front axle, unless its been swapped its a dana 60 front. That alone makes $800 a good buy. Dana 44 fronts were never rated at 4500#. It will most likely have a 205, that will at least spline to an automatic cummins trans. Yep, it probably has a 60 rear, but thats easy to change, and it sounds like he already has a 2wd cummins truck, so he already has a 70, albeit maybe a 71. I could possibly have a 70 rear, beings it a late model of the old body style and a 350.



You know me Bill, I'll calm. Probably shouldn't raise my voice on the internet though... ... . :-laf

Thanks for the info guys . My 2wd has 3. 08 gears so iwould probally have to use the other rear 4. 10 i think or change my 3. 08 to 4. 10 or the front 60 to 3. 08 . The truck should be stock it was a factory work/plow truck and was in an wreck and that is how my freind got it . I think if i could i should make the front 60 3. 08 with a 4 speed auto it shpuld make a good combo . I dont haul to heavy . but what do you guys think . I also beleive i read NP205 on the tag under the hood . but cant remember .

the np205's in gas 350's are 23 spline, to be used with a diesel transmission would require the input spline be changed to 29 spline. As previously said, you need to crawl under the truck and make sure its a dana 60. And if it is, it has 30 spine outboard axles, rather than 35 spline, unless a previous owner has upgraded to 35 spline axles. you also need to verify the ratio of the front axle to see if its the same as, or different from your existing dana 70.

the frames on 3/4 and 1 ton gassers are 7 inch the same as diesels, as opposed to gas 1/2 tons. if it was me, I would convert your diesel to 4wd, since all you would have to do is change out the front axle, change the input shaft to 29spline of the transfer case and bolt it in, and since you're mating shaft to shaft you will need a 29spline coupler. since the frames are both 7 inch the cross-member support will work.

 

[Simplysmn]

the 205 from a gasser is the Same spline trust me I am useing one and did nothing to it but slip the coupler on shaft the only difference I saw was the back yoke for driveline takes a bigger joint but that will not hurt what so ever if you are looking at down time for your truck then buy one complete and ready to roll it will save you a lot in the long run

Correct me if I am wrong but the 5 sp 205 is the one that is a 29 spline count . that would be the only reason to have to change shaft .

Yep, manual is 29 spline, auto is 23 spline.

Dana 60 front is a dana 60 front. No OEM's used 35 spline outer shafts. A 1992 gasser 60 front is going to be exactly the same as a 1992 diesel dana 60 front. The 205 like I said above will likely spline to an automatic cummins transmission. I do agree, that it will likely not spline to a getrag.



If you are wanting to run 3. 08's, just pass on this truck, and look for a dana 61 front with a 3. 08 already. Or you could buy this truck for parts, and look for a guy that has a 61/71 set, and will trade. Most around here will agree that a 3. 08 won't go into a 60 front, and nothing will fit in a 61 front except a 3. 08.



You should decide what you want the end result to be, then start looking for parts. If you want 3. 08's a OD and 4x4, maybe you should start looking for an old 89-91 with a 727 4X4. If you want a 4:10 geared trailer puller, then that is the front axle you want. If you want to run a automatic, thats the t-case you need. If you want to run 3:55 gear middle ground, then those gears can be put in that dana 60 front with just time in setup and a ring and pinion.

I guess i need to decide what the truck is used for witch is mostly work around the house so 4. 10 should make it a great work horse . If i want great mpg i should get a moped :-laf. The info is great guys thanks i just wanted the 411 before i ran blindly into a brick wall. Now its time to pick a direction and charge . Any body know a good place to get a 47rh 4x4 core ?
