    Farook I would suggest just finding a D44. Not worth it in my opinion to do the 8.8. If you want the discs it would be easy enough to grab them off a ZJ.

    i just sold a dana 44 from a xj.
    i was under the impression the 8.8 is stronger r&p
    same bolt pattern, thicker housing, and some with gearing to
    match my 96 cherokee which i think is 3.54
    also there is no carrier break so all gear sets will fit the carrier
    and ive hear that the currie hi-9 uses the 8.8 gear sets.

    + it will be coooll

    Found some info on Pirate.

    8.8
    Benefits:
    Larger ring gear
    Thicker tubes
    31 spline
    Availability
    Disc brakes

    Disadvantages:
    c-clip
    Less ground clearance
    Not exactly Jeep width
    Not bolt in, so you better learn to weld and get good at it



    D44
    Benefits:
    Bolt in available
    More ground clearance
    Larger aftermarket support

    Disadvantages:
    Drum brakes
    30 spline
    8.5"? ring gear
    Smaller tubes
    More expensive if you are getting one from a TJ

    I know when I did mine I needed a Spicer adapter at the axle. Not sure if you will run into this with the XJ but due to the pumpkin being offset on the 8.8 I required an SYE and Double Cardin shaft. Personally I gave up and said f it and went with a Super 35 that's what was in it when you went for a spin way back when.

    Why are C-clips a disadvantage? Is it that they aren't strong enough to hold the axles in place?

    ^because if you snap a shaft the axle is no longer retained in the axle housing.

    Disc brakes make the c-clips a mute issue. The real downside to C-clips is if you have a lunchbox it can be a PITA to remove a shaft but with practice it gets easier.

    I finished my 8.8 swap about 2 months ago. I had a 29 spline 8.25 that I didn't want to sink money into. I had a XJ 44 lined up for $300 bucks. The decision came quickly once I spent some time comparing the 44 and 8.8. Side by side the XJ 44 looks like a toothpick.
    The disc brakes are icing on the cake.
    Including locker, diff cover and new everything at the ends I put about $1300 into it.

    ^ya but not all 8.8's come with disc brakes. I know i'm nit picking but these are things to consider. I am a firm believer 35's and down build what you have 37's and up time for 60's.

    Pretty sure a super 35 will run you about 1300. its easier aka less headache.
    For my self I think thats what I would do. Putting an 8.8 in a wj would be a pia.
    Largest tire size for a wj is 35s ...
    I know 8.8s are easier to put into a vehicle without abs or speed sensors in the rear axle

    one more thing if you do decide to put in a 8.8 get one out of a 98 and newer with trac lock, and i belive they are only about an inch wider

    Ya that was what I was asking - the discs will hold the axel in if it is broken. In this conditon, can you limp home or are you better to throw in the towel completely?

    ok, bit of false info in here;

    - discs will NOT retain the axle shaft, have a look, the caliper bolts are 10mm I think, x2... if you've just killed an axle shafts, its not about to be retained by 2x 10mm bolts.
    - the Ford 8.8 is NOT wider then a stock XJ rear axle, unless you pull one from a fullsize truck (F-series) if it comes from an Explorer its a little over 1" narrower, which can be made up with a spacer... or left the way it is and you won't notice it unless you sit back and look for it... but your turning radius may tighten a slight amount (wider front = tighter turns)
    - don't buy an 8.8 because its stronger then a D44, you can argue one over the other till your blue in the face, shafts are near same strength, bottom line both are good, for me the 8.8 can be found anywhere... XJ D44 not so much.
    - dumping money into a D35 still leaves you with a D35... a D35, the worst of all worlds. $1000+ just to get near D44/8.8 strength, no discs, weak axle, etc etc.

    the swap cost can be as little or as much as you like;
    - get axle from junker, cut off old brackets, buy or make new ones (leaf mounts are simple right), measure, burn in, mount, heat centersetion/tubes and weld together, then find u-joint flange, install, go. = cost of axle + $100 maybe
    - get axle from junker, remove old brackets, buy a kit (TMR distributes up here) burn it in, grab a locker (lunchbox or carrier replacement) find the flange (or replace with a yoke), buy a dif cover (TMR again) make a truss and tie it into the dif cover, and go. Can also install a Super 8.8 kit for no c-clips, little wider stance (+5/8" either side) and alloy shafts. = cost of axle + $600 or more depending on locker choice + $600 super 8.8 kit

    or look for one going on sale every now and then...
    insert something witty here

    Go to car-part.com ... Look up 1999 ford explorer. rear axle assembly. pick 8 cyl. 3.55 gear ration which i believe is close enough to your ration (if you do have 3.54). I could be wrong though. And if I am I hope someone can correct me on that. Search all of ontario and you will find a few for sale. I have an 8.8 in my TJ and now I'll be putting one into my YJ. I just did the search and there are some for 200 to 300 bucks.
    90 YJ - Stock for now.
    01 TJ - 4.0L 5 spd. Ford 8.8. 4" lift. 33" procomp AT's.

    I got a flange yoke from M.O.R.E offroad. I cant find it on their site right now but here is a link to another site. Here is a link http://www.knowwhere2jeep.com/catalo...ducts_id=11344
    Basically this is what you want to look for . "Dana Spicer Ford 8.8 Flange Yoke 1310 U-Joint" You could probably find one closer by. Its good to call around.

    Walk into a NAPA with the spicer 2-2-1379 part number. I did and I got for $22 bucks out the door!. There are actually 2 different part numbers for that part. It was previously a 2-2-935 or something like that. If you google the 2-2-1379 you can read all about it.
