I have an '01 XJ, stock suspension/tires, etc. It needed new hubs, so I bought the Moog brand P/N-513159. I also bought new dust shields, hub bolts, and axle nut. I cleaned everything up really good. Installed all the parts carefully and had no issues with the parts going together (did not have to fight anything). Hub bolts were torqued to 75ft./lbs. as per the service manual. Installed the new axle nut with washer and torqued to 175ft./lbs. as per the service manual. Even with everything seated flat and firmly against the hub mounting bracket, the axle nut will not go on far enough to clear the cotter pin hole in each of the axles. Has anyone ever noticed this before with other replacement hubs? It seems like the nut has to go on about an eighth of an inch further. I also noticed that as I was tightening the axle nut, it was pulling each of the axles out of the axle tubes (again, an eighth of an inch). So it appears that the depth dimension of the Moog hub was slightly larger than the depth of the stock hub, and was seating against the mount bracket sooner. Im not too concerned about the inner axle-to-differential tooth engagement, as the total engagement is about 1 3/4" and giving up an eighth inch is minor, especially with a stock/street driven rig. I know I can also just look for a thinner washer to put under the axle nut to take back some spacing. Just wondering what your thoughts and/or experiences were with this? Thanks
