Hello and welcome to just answer Jeep. If you have a good set of tools, (ratchet wrench, extensions, sockets, etc.) then you could probably do this. The main thing is to disconnect the negative battery cable before doing the work, and you will need to get the Jeep up onto some sturdy jack stands or ramps. It basically involves removing the large cable from the starter, the small wire from the starter, and the bolts that hold the starter to the bell housing. Here is the procedure for doing this, and I hope this information is helpful. Let me know if you need more assistance with this,

Chris.
