Hi. I am trying to install a new hub assembly in my 2000XJ. I have bought two different hub assemblies from two different auto part stores. Both hubs have been about 1/4" out when I try to put my caliper back onto my rotor. I have read a few posts about differnt hub assemblies but how do I find the one for my vehicle. (My stealership wants over $400 for an OEM one.) The auto parts store only list the one hub assembly for a 1992-2001. If I ordered a hub for a 2000WJ would this work? Does anybody know part numbers?
