Timmmmmy Posted March 4, 2014 Share Posted March 4, 2014 jeep wrangler TJ DANA 44 diff set complite 4.10 - $180 http://vancouver.en.craigslist.ca/van/pts/4356135080.html I found a Chrysler dealer ship selling this. They said its from a very low KM rear dana 44 axle off a TJ. I am wondering if this diff will fit my factory Dana 44 that came on my 89 Comanche Metric Ton. Now IIRC the only TJ to have 4.10 stock would be the Rubicon, also would the carrier not be lockable? What am I looking at here? Apologies for the lack of better info or if the answer is obvious, not the most knowledgeable in this area. PS you may remember asking gearing questions last year as I was about to pull the trigger and ditch the 3.07's. Long story short thousands needed to be put into the trucks engine and transmission... It was bad year for maintenance and I could only spend so much in a year in my truck. Hoping this might save me some money and let me re-gear this year. Thanks in advance!

87Warrior Posted March 4, 2014 Share Posted March 4, 2014 Seems like a waste of $$$. Even if the gears are 4.10, very few shops will set up used gears. You would also need new bearings and seals. Not much value in the stock axle shafts or diff cover either. You can install 'thick' cut 4.10 gears on your 3.07 carrier. I will be installing a TJ Rubicon rear locker in my MJ when I get to that point in my build. The TJ Rubicon locker/carrier came with 'thick' cut 4.10's from the factory as it has the 3 series carrier. Link to comment Share on other sites More sharing options...
Timmmmmy Posted March 5, 2014 Author Share Posted March 5, 2014 So I spoke with them again. They said it was from a Rubicon and has an air locker. The guy who is a heavy duty mechanic assured me they would fit my 89 D44. But I'm not really sure what it would take to set up the locker. I'm not the most mechanically inclinned and would be having a mechanic do it. Their is a guy who installs (Even used) gears for very reasonable prices. so its an option. It would be nice to have a locker but it sounds like it would be pricey and complicated. Also the previous poster mentioned running 4.10 gears on my current carrier but I beleive the carrier break is below 4.10, I would need a new carrier regardless to run the 4.10's. If its not to chalenging to set the locker up I might consider it otherwise I will let this pass I think. Link to comment Share on other sites More sharing options...
87Warrior Posted March 5, 2014 Share Posted March 5, 2014 You can install 4.10s on a 3 series carrier, if you use thick cut gears. This is how Jeep did it on the 3 series carriers. This will not work in the D30.http://comancheclub.com/topic/34433-gear-questions/ From out very own: Yes I do. :yes: 4.10 D44 with Yukon "thick" gears, Honda Passport Trac-Loc limited slip 2.72 - 3.73 carrier. No problems. A Rubicon locker is worth what that dealer is asking, if it is not broken. The Rubicon REAR carrier is a locker AND a limited slip. You get get the best of both worlds. However, they are not known for strength by folks to run locked all the time. However, I have not broke a rear rubi locker in my 03 rubi. The Rubi carrier is a 3 series, so gears that are higher numerically than 3.73 must be thick cut.You will need to install an NPT low pressure nipple for the air tubing into the housing center section and will need to create a small notch the into the right side bearing cap for the locker air diaphragm.You will also need to supply wiring and a switch for the low pressure air pump and the tube between connection points.If none of that scares you, you should be fine with the install.. To activate the locker, it is most simple to find a stock TJ Rubicon locker pump. When powered on, the pump will pump up to the desired 5psi to lock the locker and maintain that pressure. When you want to unlock, simply remove power the the air pump and it will bleed off the pressure. New TJ Rubicon locker pumps sell for about $150 last time I checked.

Timmmmmy Posted March 5, 2014 Author Share Posted March 5, 2014 Hey Warrior, I really apreciate you posting that. I'll talk to my gear guy and see if he is up to this. If it works I would be getting a locker out of the deal in staed of just a re-gear. This may be a dumb question but could I just instll the diff without hooking up the air lines? Would it function as a normal or would it need to be hooked up? Its my daily driver so if i could instal the gears and notch the bearing first. Worry about installing the pump and running lines afterwards. I can't have the truck down for more than a day or two. Might be an option. for me. Thanks again.

a4xnut Posted March 5, 2014 Share Posted March 5, 2014 I've never seen the TJ Rubicon's D44 locker, but I've seen D44 Powr-Loks, TracLoks, Detroit Lockers, True Tracs and open carriers with and without lunchbox lockers... and that picture in the OP's link looks an awful lot like a standard D44 open carrier. In the pic, there's also what appears to be a crush sleeve. I know the aluminum D44's in ZJ's have a crush sleeve, but XJ/MJ/CJ/Ford/Chevy/ International/Dodge D44's do not. I don't know which way the TJ went, but if it's got a crush sleeve for pinion depth adjustment, I wouldn't think the pinion would work in a shim type housing. I wonder why they are selling the carrier bearing caps with the gears. Those caps are matched to their housing, so it's unlikely they would be any good to anyone anyway. There's also a dirty/rustly looking piece with splines that I'm not sure what it is... it reminds me of a spool, but with only six bolts in the periphery, it wouldn't be a spool for a D44.

Just make sure you put some sort of plug in the air line. You don't want water or dirt in there. Link to comment Share on other sites More sharing options...
Timmmmmy Posted March 6, 2014 Author Share Posted March 6, 2014 Thanks for the replies, I'm going to stay away from this one. Turns out it isn't a dealership selling this like I originally thought. I'll keep looking or just go with new parts. Thanks for the help guys. Link to comment Share on other sites More sharing options...
FrankTheDog Posted March 6, 2014 Share Posted March 6, 2014 Pretty sure that's from a D44A from a WJ. The rusty splined 6 bolt piece is the driveshaft yoke, CV style. The cover isn't a standard 44 shaped cover. The carrier is definetly a stock open carrier. Nothing special to see here folks, move along. Don't bother doing business with who has it either. They either don't know what it is or just trying to make a quick buck. Link to comment Share on other sites More sharing options...

I thought that might be what it was, but hadn't seen one and when I googled Dana 44 yoke, nothing that looked like that came up. Link to comment Share on other sites More sharing options...
