No, you would have to alter the bolt pattern on either the D44's flange or the brackets/backing plates of the disc setup you plan to use as well as placing a .023" (1/4" is close enough) spcacer between the bearing retainer plate and seal/bearing to compensate for the thicker disc brake bracket/backing plate.Does anyone know if the rear disc brakes from a Grand Cherokee (WJ, ZJ, etc..) Dana 44 is a direct bolt in, or even if it requires some modification, upgrade for a factory (1987) XJ Dana 44? I searched but couldn't find any info. Thanks.
i have the crown vic brakes and i just flipped one side so both calipers are in the rear, easy enough. crown vics also have slightly bigger calipers than exploders i believe.

Yeah but, that puts one e-brake cable on the bottom and the other on the top.i have the crown vic brakes and i just flipped one side so both calipers are in the rear, easy enough. crown vics also have slightly bigger calipers than exploders i believe.
The Grand Cherokee D44 (D44A) uses an aluminum center section and C-clip axles so, it's an entirely different animal.Really? Even though both axles are Dana 44's? Why would the Grand Cherokee dana 44 and the xj dana 44 have 2 different bolt patterns? I can understand the spacer and the axle/wheel lug pattern (5 on 5"verses 5 on 4.5"). And do either the dana 35 or 8.1/4 have a similar flange bolt pattern to the Dana 44?

It's no hassle at all in fact, you couldn't ask for an easier modification.....you just unscrew the end cap on your XJ's valve, replace the internals (and end cap) with the GC's stuff and you're done!.....no cutting or flaring of brake lines........As far as the proportioning valve is concerned, I'm not doing all that hassle of mixing parts, I'm just going to install an adjustable valve and be done with it. I have ABS right now and I have to do the '96 and up booster upgrade and associated brake line mods anyway so I'll install the adj valve while I'm at it..........

This is the best bang for the buck, especially if you you get the calipars without the ebrake mech.
Really, Oatmeal is correct.
The axle may be the same axle (D35 is a D35, but the XJ44 is not the same as the Grand's D44a), but they are from different vehicles. The flange bolt patterns are different, no rear disk brakes from a Grand Cherokee axle bolt onto an XJ axle without modification.
Also think of this, the XJ44 production ended about 4 years before the Grand Cherokee even came into existence, and more until the D44a came out. If they changed the center section design and material, all the internals, etc, why would it make sense to retain the same bolt flange with an axle that was discontinued?
