Gunner357 Posted September 16, 2011 Posted September 16, 2011 I have a chance to get a rear MJ dana 44 for $125 I don't know much about axles but it this a good swap and what is disco
Boots Posted September 16, 2011 Posted September 16, 2011 That's the axle I swapped into mine. It's a good axle and that's not a bad price either.
Incommando Posted September 16, 2011 Posted September 16, 2011 That is the most desirable rear axle and that is less than half of what I usually see them go for..
mvusse Posted September 16, 2011 Posted September 16, 2011 I have a chance to get a rear MJ dana 44 for $125 I don't know much about axles but it this a good swap and what is disco That is an incredible price for a 44. Jump on it before it's gone or the owner comes to his senses. A disco is short for a central axle disconnect. A vacuum system to disengage the passenger side axle shaft on the Dana 30 front axle when in 2wd. It had problems (vacuum lines get caught off road and ripped off leaving you in 2wd) and two piece shafts with the larger u joints you want are hard to find. It is relatively simple to get rid of it and run a single piece shaft, though.
STERLING STINGER Posted September 16, 2011 Posted September 16, 2011 Lucky Ive been hunting for one for like 6 months now!!
ParadiseMJ Posted September 16, 2011 Posted September 16, 2011 Gear ratio? What's your 30 running, if you have a 35 in back gear ratio has to match the 44. Just sayin' If you have to change ratio that $150 can get expensive fast.

The central axle disconnect on the D30 is usually just referred to as the CAD.
HOrnbrod Posted September 17, 2011 Posted September 17, 2011 Yep, that's an excellent price for an MJ D44 axle. I found one closeby in TN for $225 (also came with an extra Trac-Lok diff), mileage unknown, which I thought was a good buy. I had to go to 4.10 so I knew I'd have to regear BUT I wasn't counting on the bent left axle shaft, ruined axle bearings, pinion leak, right side axle leak, etc. etc. So yeah, I had the whole thing rebuilt, and the cost can add up fast. :eek: Such is life.............
High2by Posted September 17, 2011 Posted September 17, 2011 That's a killer price for a MJ D44!!!!!!!! Good find!!! :cheers: We have a PAP just a few miles from me. You can get a 31 spline 8.8 with an assortment of gear ratios, disc brakes, and even some with limited slip diffs for less than $100.00 out the door and since I haven't been able to find a deal like this one........in forever, I think I'm gonna opt for the 8.8. Straight bolt in is always the way to go when available.

Please consider a Ford 8.8 with disc brakes as considering I spent over $400 on my MJ D44, with a 3.73 gear ratio, I have seen Ford 8.8 axles go for under $200 ready to install with some welding and many with no issues.HTH Dog
HOrnbrod Posted September 17, 2011 Posted September 17, 2011 Naw Joe, I'm glad I held out for an MJ D44 in spite of the problems I had. I wanted to "keep it in the family" so to speak and never considered a Ford axle. :ack: Oh, wait! I've got Ford Exploder disk brakes on it. So much for keeping it all in the family. :doh: :agree: w. Joe.
mvusse Posted September 17, 2011 Posted September 17, 2011 Say Don, why not dump those Ford :ack: disk brakes and install a a set of ZJ ones?
HOrnbrod Posted September 17, 2011 Posted September 17, 2011 I used the Ford brakes on the D35 years ago because the Teraflex conversion kits were cheap then. They are easily swapped over to the D44, and knowing that some day I'd get the 44 someday, I went with the Exploder disk set. Suppose I could have used ZJ brakes too, but the Fords were an easier option at the time and the cost was about the same. :cheers:
Gunner357 Posted September 18, 2011 Author Posted September 18, 2011 just found out more info on the mj dana 44 Welded spider gears, LSD carrier is cracked Pinion gear is missing a chunk Housing and shafts are good w/ complete brakes and e brake cables so what do you guys think is it still a good deal :hmm:
mvusse Posted September 18, 2011 Posted September 18, 2011 Seems like you got a housing with brakes and shafts. Everything inside the diff would need to be replaced. This would be carrier, gears, master install kit and possibly seals.
cweemanrun Posted September 18, 2011 Posted September 18, 2011 find a 8.8 out of a ford explorer they are just as strong as the dana 44

What difference does that make, Don? The pinion gear is missing a chunk and the carrier is cracked...

What difference does that make, Don? The pinion gear is missing a chunk and the carrier is cracked... Regearing = new gears = easy chance to get new carrier, especially since the D44 has a carrier break..
HOrnbrod Posted September 18, 2011 Posted September 18, 2011 ^ Yep, that's the difference. If he's planning on regearing to 4.10 he'll need a new carrier anyhow. Unless he uses thick gears.
mvusse Posted September 18, 2011 Posted September 18, 2011 That's what I mean. If he keep the old gear ratio he needs new gears and a carrier. If he regears, he needs new gears and a carrier. No matter what he does, he still needs gears and a carrier.
HOrnbrod Posted September 18, 2011 Posted September 18, 2011 Okay, we meant the same thing. :cheers: Either way, $125 isn't a bad deal IF the axles are okay. Sounds like this D44 has been rode hard and put away wet a lot though............
