What's it worth? MJ D44

I paid $100 for my 4.10 8.8 complete, you just have to do the legwork at the local junkyards.

 

You pick the axle out of a pile of axles, or pull your own, and you can get it for $100 to $150. You go to a salvage yard and they pull you one off a sheld, you'll pay $350+.

Why pay that when you can get a Ford 8.8 with discs, 4.10, and limited slip for $100 to $300? Much stronger than a D44.

 

Because the MJ D44 is bolt in.

 

Much stronger is highly debatable....

The axle shaft strength tested by Warn Ind:

F8.8= 6,500 (lb. ft.)

D44= 4,600-5,000 (lb. ft.)

D35C= 4,000-4,300 (lb. ft.)

COT: Continuous output torque rating

MOT: Maximum output torque rating

 

(Numbers from January edition of Fourwheeler, page 60.)

Dana 35 rear axle COT: 870 MOT: 3480

Dana 44 rear axle COT: 1100 MOT: 4460

Ford 8.8 28spline COT: 1250 MOT: 4600

Ford 8.8 31spline COT: 1360 MOT: 5100

Dana60 semifloat COT: 1500 MOT: 5500

Still have to discuss the tubes in the axle housing.

 

also- I have sold over 25 XJ/MJ D44s, and about 12 8.8s.

 

Whenever I go to the JY I see about 10% of the 8.8s with broken axleshafts. I have yet to see a broken D44 shaft in the JY.

 

Torque in a fixture isn't real world. (And I highly doubt the 28 spline would have a real world torque rating over a D44)

well since its literally a DIRECT swap in, id say priceless lol.

I think this is the best answer thus far. I am not a hardcore wheeler and I doubt I will ever brake the D44 (heck I am yet to brake my welded D35) Not to mention the D44 is a dirrect bolt in. no fabbing or adapters required.

I have seen a lot of parts breakage on the trail. As for what is stronger the 8.8 or the d44.. I don't know, but I know I wheel the piss out of my rig with an 8.8 and no failures. I also know of another guy with a d44 in his tj who broke the pinion with less then 10000 miles on his rig.

 

 

The plus to swaping in a 8.8 is they are cheap, have disc brakes, and come with a lsd and 4.10 gears.

 

The d44 you will have to more then likely swap gears (140 for gears plus time and labor.. did I mention the install kit), add disc brakes... figure a couple hundred for that.. and then add a LSd ... another few bucks. You tell me what is better

Seems to me like one 1/2-ton axle's not gonna last much longer than another. If you're gonna bust a 44, do you think an 8.8 is gonna be unbreakable for ya?

 

I think things like locker, gear, and brake selection are bigger deals, and just finding a nice conditioned axle. All this is not considering if you're planning on throwing bucks into things like chromoly shafts though.

I have looked into doing an 8.8 and it is not just buying the axle and putting it in. Most if not all I have come across need brakes. If the hardware is not missing it is worn. Also, so what if you do not currently have 4.10 gears up front? Then you need to swap those out also to match the rear. As I stated in my first post (titled MJ D44 what's it worth? not 8.8 or D44?) the D44 I am getting is the same ratio I currently have, has good brakes and is a dirrect swap.

Well when I can find 31 spline shafts at the j-yard all day long.. It don't seem like much of a problem.

 

Scrambelr you are right.. for you the d44 is a direct swap, and seems like the easiest option. The 8.8 is what I am running, and has proven to be a strong axle for the style of wheeling and driving that I do. As for the 8.8 not being a direct swap... it isnt far from it. brakes are easy to overcome, and there are plenty of good condition 8.8's in the j-yard, d44's are getting harder and harder to find
