Presumably you mean remove & replace the starter...rebuilding it, a bench job, is a bit complex and best left to a full shop of specialists. Actually a good novice type job. Fairly accessable...not normally too frozen in or such. Not much damage you can do either. A couple of bolts...a couple of wires...jiggle it out...reverse procedure on install. Best to disconnect battery...as when the wires touch you'll get sparks...no real chance of injury...but can make you jump. ....and while not needing many or any particularly special tools...you would need a good basic set of sockets, wrenches, extensions...that type of thing.
