Special Note 2 Stock bearings are usually LM603049/LM603012 for the ring gear side and LM501349/LM501314 for the opposite side. Some use LM501349/LM501314 for both sides. The Auburn limited-slip differential will fit in either application. We supply 2 sets of LM102949/ LM102911. Axles that have the LM603049/LM603012 bearing will still use that bearing, but the opposite side will require the LM102949/LM102911 that is included with the differential.
