Can I swap in a Dana 44HD for my Dana 35?

In a previous post, I determined that I have to replace my rear end as just about all the gears inside are worn.

My current axle is a stock Dana 35 3.73 with track lock. I found an ad for a Dana 44A or 44HD off a WJ. It has calipers, but nothing in the ad about a track lock system. The guy is also selling a locker for it though.

So my question is, would this be a viable option for a replacement? Would it just bolt right in and would the brake lines that feed the drums, also swap over easily to the calipers?

Even if this axle is a viable option, how easy is it to swap a Dana 35 for a Dana 44? Do I need to buy a kit or anything? Sorry for the noob, questions, but I haven't had to deal with drivetrain issues much until now.

You can but i think you would be better off finding a ford 8.8 out of an explorer. The 44a has some issues and a very small aftermarket. The 8.8 has a pretty large aftermarket you can also find them in any wrecking yard cheap.

Another option you have is to find a d44 from another tj or lj and swap that in. If you dont have much to spend you could always find another d35.

If you get a d44 or d35 from a tj its a direct swap. If its any other axle you need the brackets maybe a drive shaft adapter or new yoke.

The D44 HD, more commonly known as the D44a, from a WJ is not a good option.

It is not bolt in.

It has a different bolt pattern (5 on 5) and different width (about 63" WMS-WMS).

As Jonathanjr1 mentioned, the D44a had limited aftermarket support. Only a couple lockers available and they are lunchbox style.

If I get, let's say an 8.8 limited slip, will the limited slip work? Don't I need the right electrical connection?

There are no connections for limited slip, its all automatic. I don't know if ford uses clutch packs or the newer gear type of limited slip but neither one require electric, air, or cable.

In the Explorer 8.8s that are factory equipped with a limited slip, it will be a clutch-driven limited slip.

Ford does use a Torsen limited slip (gear-driven) in some other 8.8s, but not the Explorer variant.

When I said "some other 8.8s", I could have more specifically said in the Ranger FX4 Level 2 8.8s.

Here is info from Torsen on this:
Which Torsen is in the Ranger FX4 - Level 2?
The Ranger FX4 Level 2 comes standard equipped with a pre-loaded Torsen T-2. Ranger production units will start with a 9702 serial number. Click on the following hyperlink How do I decipher the Torsen part number? to view an explanation of what information is found in the Torsen part number on a Ranger FX4 differential.
http://www.torsen.com/general/genera... FX4 - Level 2

Maybe some of the Mustang 8.8s use a Torsen diff, but I'm not sure.

Seems like an 8.8 is likely to have disc brakes. Anybody know the swap procedure there, since I've got drums in the back?

There isn't much of a procedure. There is no need to change anything else (e.g. proportioning valve, master cylinder, booster, etc.) other than whats at the wheels (i.e. drums to disks). Just get the lines hooked up. Well, you might have to get new parking brake cables.
