Thanks! I've seen this before. I guess I didn't read it clearly enough before. Cuz I called around some places and they said Grand Cherokee will not fit Dana 44's. Well, according to this guy he took Grand Cherokee Dana 35 assemblies. But, he doesn't say what all the parts I will need. I guess I could always go try to find a Grand Cherokee and try to match things up. I don't know. This sucks when I'm not really mechanical at all.

Nice! I could always ask chase from ECGS. I bet he'll know. Thanks for the heads up.

not sure, check autozone or some sort online for brake pad/rotor/calip. part numbers to see if they are the same?

From Stu's write up:
" I needed the rear disc brake assembly from a '95 to '98 Grand Cherokee's Dana 35 axle"

I grabbed mine from a 95 (not installed yet).

Nice score! what all did you grab?? I need brake lines, ebrake cables, calipers, caliper brackets, discs, backing plates and anything else I missed. Is all that bolt on do you know or what modifications are needed??

got some new toys today. This will definitely make my job easier cleaning up this axle. I didn't buy this just for the axle though. Also picked up an impact wrench. I got a air powered sander and a 21 gallon air compressor..pretty sweet!!
I forgot the best part..I got this from Harbor Freight on sale for 129.99. I also searched the internet for their 20% off coupon...20% off!

Alright, a few things. I don't believe that is a 2004 axle from an Unlimited and even if it's not, it's not a big deal. The clues that point me to that conclusion are the fact that it doesn't already have rear discs and the bearing cap isn't slotted for the Rubi locker air line.

I realize someone could have swapped on the brake drum backing plates, but you also have axles that have the appropriate 4 bolt retainers for drum brakes. That means they either tossed in some shafts and backing plates from another 44, or it's not from an Unlimited.

I don't believe that they made any rear 44's after 03 without the slotted bearing cap.

That said, no the brakes from a 96 ZJ will not directly swap. However, if you read Stu's write-up from when we did his, you will discover that they can easily be adapted to work.

What I haven't seen anyone tell you yet is you will need to pull the bearings, seals, and shaft collars from the axles you have in order to use the 4 bolt retainers for disc brakes. That means you really should replace all the bearings and seals while you are at it. Those are a Set 10 and make sure you get the 3 pieces. Some places sell the Sets without the shaft collars.

Brakes that will swap or can be made to swap are as follows-

All ZJ's
Libertys
All TJ's and regardless of the body code, Rubi's and Unlimiteds are still TJ's.

8.8 rear discs will NOT work unless you want to have a lot of machine work done and weld up the holes in the backing plate.

To swap the discs on you will need the following parts-

Disc brake 4 bolt retainers
Shaft collars if you decide not to change out the bearings and seals.
Bearings and seals Set 10
Short flex hoses
Parking brake cables for disc
Flex hose tabs for the ends to bolt or weld to the housing
Cut and flaring tools to shorten and adapt your brakes lines to the flex hoses
New longer bolts for the backing plates with Grade C top lock nuts. Drum brake bolts are too short.
Backing plates with dust shields
Calipers with new crush washers and banjo bolts
Brake pads
Rotors

You can re-use your brake line that attaches to the axle via the vent bolt.

That should about do it.

He also said there are chromoly shafts in there. If I have questions later ill be sure to ask ya! I'm out runnin around posting from my blackberry. Again, thanks a lot!

I also have a question. I noticed something that happened today. Can anyone tell me if this is going to be an issue. I noticed a couple holes that appeared after going of this area with the wire brush. It must have ripped off a chunk and left a little hole. Is this a problem?? It is also on another area in the same the area. So I have 2 holes. Should I plug it up with some JB weld or not worry about it and let the numerous paint, primer and clear coats cover it up??
