This is a New OEM Rear Axle Kit on the wheel bearing side.  These will fit both sides.  These are one of the hardest parts to get out when they get seized into the wheel bearing hub, and usually become damaged beyond repair.   There are are 3 different axles to choose from,  1: LSD ABS   2: LSD Non ABS   3: Non LSD ABS.    This comes as an assembled unit, that will fit into your existing Diff Side Cup.   This does not include the diff side boot, or clamps.  This also does not include the castle nut.

What we have found to be the best way to get these out, is to thread the nut to the outside of the threads, heat/cool/repeat, then smack it with the biggest hammer you can find.  If this does not work, you will probably need a new hub, bearing, and axle cup.  This cup is the smallest way to get a new cv cup.   The Diff side cup is what makes a complete axle so expensive, so if you can save that, you can get back on the road, and save a few hundred $$.
