Help! Is Tracker front differential bushing replaceable??

[lackndt]

I had an output shaft seal leak on the passenger side of the front differential. The joint seemed quite sloppy. I took out the CV shaft out of the differential and saw some wear on the OD of the shaft where it rotates in the bushing in the differential housing. I wanted to replace the bushing but the dealer can't find it in the parts book. Can anyone help?

Thanks
