great customer service
I called, they had the exact part. Steve talked me thru what I needed to do and all went just like it was supposed too.
I will definitely use these guys again. I went to a repair shop first for my problem, they weren't sure they could get the part... what a joke on they're part.

Right Part, Easy install
The original lower shaft snapped off during use. This new one was ordered, arrived quickly, and screwed into place in a few seconds. I reused the trimmer head and guard, which both bolted straight onto the new shaft with ease. Now it works great and we are back to WeedEater-ing the weeds! Thanks eReplacement Parts.

Unscrewed lower shaft.

Remove shaft.
Removed orange tab.
Installed new shaft.

Remove all of the parts from the old shaft, then unscrew the lower shaft from the upper shaft. Screw on the new lower shaft, then put all the parts on the new shaft assembly.

... Read morehaft 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.
