A little searching shows that the 2007+ Jeep wrangler and Dodge nitro used the same rear brake assemblies as the Liberty. That = lots of donors out there! The only trouble is that it a set of matching studs for the backing plates might be necessary as the adapter is about 3/8" thick.u2slow said:Update...
Confirmed the plug'n'play of Liberty discs on my spare 9.25" diff. Just like the cherokee link I posted above.
It would be good to have slightly longer housing flange studs, and maybe a thin shim to go on the axle before the disc for spacing (perhaps the center cut out of an old brake drum)
