The wood hole, or a threaded insert (steel)?
The wood hole issue; carefully clean it out well with an undersized drill bit, to remove all cracked, chipped or irregular crud, not "overdrilling" it to get to all new wood, but just to pull out all loose stuff, you want ridges and grooves left in the hole...... clean it out with an airhose, then mix and insert some wood epoxy filler. Let cure, then redrill like new. You can tape off the stock before hand to keep any epoxy from touching anything else and causing other problems.
