Chevy put them on trucks for a lot of years. I'm not sure about the measurements on them though.
:cool:

If you're asking about a front axle, I don't think so, but don't quote me on that. For rears, all J-20's with qtrac had pass side drop.

All 79 and earlier trucks that had D60 rears are pass side drop regardless of whether they came with a QT or D20 x-case. If you mean front D60 then no, you'll have to look at other makes besides Jeeps.

no, jeep never had a factory pasenger side drop dana 60.the best bet is the chevy pasenger drop dana 60.they are however high in price,expect to pay anywhere from 600.00 to 1000.00 for one ,then you need to do some modes to make it work.they are also set up for spring over.

dodge used a pass side drop d60 as well. from what i can gather,dodge used external lockouts for awhile before switching to the internal style like chevies. im in the process of trying to aquire a dodge 60.i figure having a d60 sitting there is good insureance that my 44 will hold up smile.gif

international also used a pass side drop,and im pretty sure they used d60 and 70 front axles.

I'll scrap the idea then...I don't thing the D44 would last long with the weight of a Cummins 6BTA overhead.

why not? what do you plan on doing with it? i dont think the weight of the engine will bend the housing,if thats what youre worried about. as for the axleshafts,R&P,how often will you be pulling a real heavy load in 4wd?

beefing the rear would be your biggest concern. i have yet to have any real trouble with my front 44. oh crap,maybe i shouldnt have said that- wheres some wood? smile.gif

A Cummins 6bta weighs around 1000 lbs dry with no accessories. You don't need to pull a heavy load to break things, 400-500 ftlbs of torque multiplied by a transfer case will do the job easily. Sounds like a good swap if you can do it. Which trans are you going to use?

-joe, I was under the understanding that J-20s with a d20 xcase had centered rear D60's. I could be wrong, but I remember Rusty Jeep saying something about that.

Someone correct me if I am wrong but I think the "centered" rears on the J20's are actually slightly offset to the pass side :D

Glad, check out -joe's reply. Up until they started to put the New Process cases in the J20s the D60s were offset to the pass side.

I would however like someone to clarify -joe's statement that even the d20 tcase came with the offset axle.

If that's the case then all I would have to do is find a T18/d20 that was behind a 360, and then modify the driveshafts accordingly? This is a swap I would like to do, but am unsure about the axles. I do have a drivers drop HD44 and a centered D60 from an '84 J20, so I do have that option as well.

My setup is a different critter all together....centered rear Dodge Dana 60, Dodge Dana 44HD front(I think anyways..could be a 60). Yes, the Jeep Dana 60 is a little offset, but not near the Q-track's offset...at leats that's what I've found.

Listen to me, I know the truth. I just went to the garage and measured the axle from my 1972 J-4000 with the Dana 20 transfercase. It is a Dana 60, 5 bolt, semi-floater. The pumpkin is offset to the passenger side by 5".

Rande, so does the d20 use a front pass. side drop as well? If so then my assumption about just swapping out tranny and tcase with modified driveshafts would work?

I posted earlier about getting a part-time kit for my qtrac, but I would really like to have a manual tranny, and for the cost of the kit I could probably find a t18 and d20 to throw in there.

Hump, Yea the D20 has a pass front offset. I also want to support the claim that the D60 rear has a pass offset. I have an 8 bolt full floating D60 rear and the diff is shifted to the pass side even though the D20 has a centered rear output.

Scotty, are you saying that dodge makes a D60 pass offset FRONT axle? If so year and should I look for?

Thanks

Any Dodge diesel 4 wheel drive from 89-93 should have a D60 with a passenger drop.

Thanks for the info frozen! Now for a couple of more questions. smile.gif Could you use a centered rear D60 behind a d20 tcase, and would there be any advantages over an offset D60?

I read your sig, and it says that your d20 is behind a TH400. I didn't realize they came that way. What would I have to do to put a d20 tcase behind my TH400 until I would aquire all the parts to go to a manual tranny(T18)?

You could certainly use a centered D60 behind a D20 t-case. This would improve your driveline angle a bit if you plan on lifting it. Otherwise it probably won't make a whole lot of difference.
You should be able to just find a T-18/D20 combo and drop it right in, provided it was behind the same motor as yours. Bellhousings and everything are the same, as is the crossmember I believe, though that will probably need to be moved. Easiest thing to do would be to get the T-18/D20 from a long bed pickup and just grab the driveshafts too. Be a direct swap.

As for the TH400/D20, they were available from something like '70-'73. They used a special adapter that's getting pretty rare and can be expensive. Personally I'd get the T-18, that way you're pretty much gauranteed not to break it. (pretty much, not totally, ;) )

Although I would recommend a dodge or chevy front 60 with disks, there was a D60 front under a production jeep..... the M715! DENNIS

Would gas tank to driveshaft clearance be an issue when using a centered axle on a previously offset rig?

Someone in AZ is selling 2 TH400 - D20 rigs on the classifieds right now :D

I second the idea of taking a good long look at the gas tank to make sure the driveshaft doesn't hit when using a centered rear diff. Just a thought.

I have my Dodge center diff 60 and it doesn't hit the tank in my J4000. I don't know about a Chero, Wag, or newer J. On second thought....maybe you should look. :cool:
