Question Axles

I'm relatively new to 4 wheeling so excuse anything stupid I say. I'm looking to do an axle swap to upgrade the stock axles on my XJ. I was told that jeep put Dana 44s in XJs with tow packages for several years. I was curious what years, if they did at all, and if so how do I recognize them?

If someone thinks this is the wrong idea please tell me. Any advice would be great. Thanks.

There were I believe about 2 years the XJ had the D44 rear axle you speak of . '87-'88 I think .The cover is not oval , but more asymetrical diamond-like .
They are a less common (not exactly rare) part to find lying around since many Jeepers are incremental up-graders and that is one of the most obvious step one upgrades . Not a bad choice at all "IF" you just happen to find one easily / reasonably priced .

Another popular choice (and very common) is the 8.8" out of an Explorer . '96+up models had disk brakes , and the 8.8 is slightly stronger . the downsides being ; slightly shorter in width (about 5/8" per side) , re-welding spring perches is also likely needed . All things considered , I did the 8.8 route and 5 years later I'm very happy with it .

As someone else will certainly mention , learn to use the "VERY HANDY" search function , this subject has been covered in insane detail about a billion times in this forum .

That 8.8 swap is awesome! Use the super 88 kit, you'll get rid of those c-clips, get alloy shafts and best of all bring the track width out 1 1/2"

Can I do that for the front and rear or do I need to only worry about one or the other?

1987-1990 in the US. Although they supposedly were used longer according to Dana, except they overlap the introduction of the Chrysler 8.25.

would the Chrysler 8.25 be a good option as well?

Well, I'd consider the 8.25 a half-step between the Dana 35c and the Dana 44. If you have one already then fine, if you don't then look for a real upgrade like a D44, Toy 8", Ford 8.8", 9", Dana 60, etc... Now if you have a 8.25 already then I'd skip the D44 and go bigger.

There are a lot of other things to consider like bolt patterns, full-width, brakes, etc... but they can all be worked around. It just depends on how strong you're looking at building it.

You're going to have to ID a Chrysler 8.25 by it's looks. All of those 'numbers' are Dana/Spicer' Bill of Material numbers.

Honestly though, I wouldn't even bother with a 8.25. There are other axles out there that are plentiful and stronger.

If you really want a 8.25 though, they can be found in '91 and up XJ's with the 4.0L with the Tow Package.

Dana 30 is the only front axle available in an xj , but for a pile of cash , you could buy a tj rubicon dana 44 front axle and install it pretty easily .

35 inch tires are too tall for a dana 30 front with any kind of abuse , and the dana 35 is to small for a stock tired xj .

The trailer package dana 44 xj is available in all xj years ,basically ,I've only found 1 in the junkyard (pick a part style , not a regular junkyard ) in 25 years of going , so I'd look to buying one private party if I wanted one , it would be easier .

The exploder rear is way easier to find , one note on the 8.8 that has not been mentioned yet in this thread :It has to come out of a V-8 exploder to have 31 spline axles , V-6 8.8 's have smaller 28 spline axles .28 spline axles are not inherently bad , just undersized for the same cash lay out for axle .

Actually a JK rubicon axle would be a better option, just need to find a rear with the matching lug pattern.

If you are looking for a cheap Chrysler 8.25 I have got one that I would part with, I would guess though that shipping would be more than it is worth.

Yeah, JK's use a 5x5 pattern instead of the 5 x4.5. Adapters to make the axles match are out there.

My 8.25 looks much different than the one pictured. It is not rounded at all, but is straigh across the bottom.

You might be happier with 33's. Less lift, less axle drama, and you only lose 1" of height instead of 2" like most people think.

the reason I wanted a 5.5 is so I could end up with a rubicon express long arm. Is the shorter lift, like the 4.5 that isn't a long arm, gonna be able to provide the same flex. I thought 35s would be the best option, but I would easily go with 33s. Whats the best option for this set up axle wise?
