D35 for D44

I have a friend who wants to trade me a D44 with a 28 spline and 4:56 gear for my D35 with 4:10 gear (not sure the spline). But here is the problem, the lug pattern on the D44 is a 5on5 will my wheel fit on the lug pattern? I believe that my wheel is a 5on5 1/4 (or whatever it is stock) its a 1998 4 banger. I was going to regear but if the D44 will work then I won't!

Honestly I would by need wheels if I was in the situation. But I'm guessing since both of them are Dana and both I'm guessing are stock axels from jeep. They will be the same.

Honestly I have no idea why your friend would trade you. That's kinda of a not so smart move. But I guess it's to teach it's own.

That was actually my next question the D44 is from a 80's model monte Carlo. Will it fit in the jeep? And he is building a dirt track car and wants it to be light as possible cause it's only going to be running a 350.

the stock bolt pattern for a Jeep TJ is 5-4.5, if it is 5on5 you can get spacers for the front and adapters for the rear, here is the thing, why is he willing to trade you? to me I would questions the motives, and do you have 4.10 gears in the front? if not your going to have to 2wd with no front driveline in it until you gear both to match, you cant just leave it in 2wd, you have to remove the front driveshaft if the ratios are different

What is that D44 coming out of that it only has 28 spline axle shafts? MJ? XJ? Im drawing a blank on what D44 had only 28 splines.

Two things of note.. Your wheel bolt patern is 5x4.5 so it won't work on that front. Also your front and rear axles have to be geared the same so if you change from stock in one axle your gonna have to have the other axle regeared as well if you want to use the 4wd.

The only D44 that is a bolt in for you is the TJ/LJ D44 which has 30 spline axle shafts. All other D44's that you will come across will require fabrication to make work. You also have to consdider the drive shaft as well

My opinion pass on this

You don't have to remove the front driveshaft, but you can't use 4wd. If no power is being applied it doesn't matter what the ratio is

I would pass as 28 spline 44 is not much better than your 27 spline dana 35. Plus you have to get brackets etc... welded on, unless I missed that part.

Yea that's prolly not worth it. Tell him to go buy a new axel or go to a junk yard.

This is absolutely wrong, if you dont have lock out hubs, both shafts turn inside the transfer case, if those shafts are turning at different speeds you will have problems, if you have 2 different ratios one of the driveshafts need to be removed to avoid damaging the transfer case.

there is no power to the front output until its taken out of 2wd as far as I recall.

the NP231J is a shift on the fly, have you ever heard a gear grind when shifting to 4wd? why do you think that is?

Alright I have seen some right and wrong answers here.

A Dana 44 out of an 80's Monte Carlo would work in your Jeep...however, you will need to fabricate mounts for control arms, spring perches, a re-gear for the front axle or the rear will need to be done, the bolt pattern is also wrong. I'm not sure how wide a Dana 44 from a Monte Carlo is but it's a good bet it's not the same width as a TJ axle. It can be done but it's not free and will cost a bit of money unless you can do most or all of the work yourself. My advice is to pass on it and look for one from a TJ.

As for the four-wheel drive you can leave the front driveshaft connected even if the axle ratios are not the same in both axles as long as you do not engage four-wheel drive. Yes the front drive shaft will spin but you are disconnected inside the transfercase while in two wheel drive.

Because your front and rear driveshafts are turning the same speed when your axles are geared the same as long as you aren't spinning the rear tires faster than the front. The transfer case also is synchronized internally similar to a manual transmission. Now that is the case for high range but when shifting to low range you need to stop or barely be crawling less than 3 mph in most cases.

There is a "Mode shift synchroniser" that can be easily damaged, as well as then damaging the main gear, chain and shaft, by the two shafts turning at different speeds.

I know about regearing the front as well and I was planning to regear. And I will be doing all the work. Ok so since I'm not going to go with the monte Carlo D44. Should I consider the ford 8.8, or the super 35 kit? Or should I continue looking for a D44 off of a jeep? My only draw back to the ford 8.8 is having to regear that as well because I really want either the 4:56 or the 4:88 and the ford 8.8 is a 4:10:1 which is what I have now that I want to get rid of. I do have all of the proper tools and equipment to do the job.

the 8.8 is the most popular choice, its a tiny bit narrower than the Š-35 but I think only 1.5" or close to that, they are tough, thats what I would do in your place, then you have matched ratios until you get the gear sets to do the regear.

Chances are you would have to regear a D44 as well, right? Not sure why that's a downside to the 8.8.

Only real downside I see to the 8.8 is it's just a large axle. But, you get more strength than a D44 so you could argue that the increased size is worth it if you're moving to larger tires. A D44 is certainly easier since you don't have to worry about welding up brackets and such, but unless you can get an amazing deal they're usually overpriced (at least in my opinion). Personally, I've got an 8.8 sitting in the garage waiting for a free weekend to get swapped under the Jeep.
