Separate lower shaft from upper shaft.
Remove string head from lower shaft and install on new lower shaft.
Install new upper shaft into body of trimmer, note notch on upper assembly and slot in trimmer housing as the alignment point.
Install new lower shaft assembly along with drive cable into upper shaft assembly, aligning the upper and lower shaft assembly with the notch on each piece. You may need to slightly turn the stringer head left or right so that the square end of the drive cable seats into the couple inside the drive end of the trimmer assembly (at the business end of the engine). Once seated correctly, you should feel resistance from the compression of the engine as you try turning the trimmer string head, and you will be able to tighten the two halves of the coupler sleeve. Do not try forcing the two shaft halves together. Try again to seat the drive cable simply by rocking the stringer head back and forth until you feel the square end of cable seat into the coupler on the end of the engine inside the trimmer housing.
Tighten the torx screws on the trimmer housing and tighten the coupler that holds the upper and lower shaft assembly together.
Install the handle from your old upper shaft assembly onto the new upper shaft assembly, just above the coupler at your preferred location, most comfortable to your reach and grip during operation of the unit.
For safety, and to test without starting, disconnect the spark plug wire, pull the start rope, and observe stringer head. If the stringer head turns without issue, cable should be seated properly, and the unit is ready for use.
Head of weedeater would freewheel. Occasionally, the machine would screeching halt.
