Dana 44 rear disk upgrade...HELP?

[Maine Jeepah]

OK I have all these parts sitting here, and it looks like it will work, just looking for input form people tht have done 44 disk upgrades.

88 GW 44 REAR
85 Chebby rotors.
calipers for the chebby, and weld on GM brake brackets.

I'm looking at all the stuff, and I need to mount the rotors on the inside of the end of the axle end flange, with longer studs obviously.

I'll have to take off the bearing retainer plate, and then mount the rotor.

once i have it all back together with bearings pressed on, I'll be able to install it, and line everything up for the weld on brackets.

Besides what I've stated, anyone have any advice...am I missing something?(beside not having an ebrake)

Anyone know of rotors that could be mounted on the OUTSIDE of the axle "flange" like the drums were?
That would save me a lot of work.
I can always go look for rotors at the parts store that might work.

The chebby ones dont have space to clear the flange.


EDIT: Also the chebby rotors have lug studs that are larger then the ones in the waggy axle flange,
Only way I think I can make THAT part work is to fin studs that will fit the chevy rotors, and press into the holes on the waggy axle...looks liek they will need to be machined out for larger studs.
The stock chevy ones (the pressed in part) is too long if I put it all together and machine the waggy axles...it would interfere with wheel mounting.
Is this a waste of time?
Thanks for any input.

SSB sells a kit... also there is a guy on EBay that sells a kit for less. Some members here have experience with his kit installed on their rigs... do a search, or they might chime in on your posting. Good luck. smile.gif

I know about the kits...I guess the only real thing keep ing me form doing this right now is the lug stud difference.

If I macined the axle flange I'm afraid I'd remove too much material.

I am not sure that machining the inside of the rotors to fit the axle form the outside would work...
Just wondering if anyoen had done their own set up...wish I worked at an auto parts store...I probably could find rotors that would fit...might need my six lug bolt pattern macined into them but that would be easy I suppose.

Thanks.

The guy on e-bay.....e-mail him....he said he can get kits with all the right lug patterns :D

In case anyone else is interested.

I found 99 Yukon 4wd front disk rotors will fit my 88 waggy rear axle.
I have 1/2 ton chevy calipers that appear ike they will work with these, and I just need to get some weld on brackets from the stock car boys and set it all up.

Only issue is that the waggy studs ae smaller then the holes in the Yukon Rotors....I will need to make sure the rotor is set properly...maybe get some spacers made to even it all out.

hate to be the bearer of bad news,but the factory front caliper bracket will not center the caliper over the rotor correctly. ive been there allready smile.gif put the bracket in front of the flange and you will have to clearace a pad to use in the rear,behind the rotor. if you cut it and weld it onto the tube behind the flange,youll hvae to clearance a pad to use in the rear.

i used 91 chebbie k1500 rotors,wich slide over the hub just like a FWD car rotor on the chebbie IFS. they look like they were made for this reason. they slide on and off the flange so you dont have to screw with a bunch of machine work to use a stck front rotor on the rear of the shaft and cut the acess hole for the retaining nuts,etc. use the "heavy duty" chassis rotors,as they are same thickness and diameter as the front. the "standard chassis" will e smaller and skinnier. i got mine at the 'Zone for 24.99 apiece.

after trying to use a front bracket,i ended up making one out of some very thick plate steel i got from the local recycle yard.i welded it directly to the housing about 1/2 inch behind the flange. once you get the bracket made,position it so that it puts the rotor in the middle of the rotor. id made a cardboard template and talked the guy at the yard into cutting out the rough shape with his plasma cutter,so all i really had to do was smooth it out and play with it till it fit the way i wanted,and drill/tap the holes,wich in my ccase turned out to be 7/16,20(fine thread) but ive seen different thread caliper bolts.

the hardest part in all honesty was drilling the hole in EXACTLY the right spots,cause if theyre alittle off,the caliper wont slide correctly.take your rtime in drilling/tappig your holes.

further questions? smile.gif

Actually I will be using weld on type brackets that race car builders use.
They are about 6 bucks a piece, and come radiused for 3" tubes, or blank, or clamp on.

Looking at the GM calpier I have wth the yukon rotor on there, it appears as though it shoudl work...just a matter of lining up the bracket and welding it.

We'll see...I can always make a custom one if need be or adapt the race car ones.

Thanks.

Try A&A Manufacturing (http://www.aa-mfg.com/) for cheap brackets.

Here is a good article for a Land Cruiser Rear Disc Swap (http://www.birfield.com/~morgan/tech/rdb/)

Are you guys talking 5 or 6 lug rear??

I know the k1500 is 6 lug not sure about the Dodge rotor?
