Monoprice uses really cheap non-standard parts, sorry yours broke. Mine did the same thing a couple weeks ago.
What you really should do is buy this metal extruder assembly for $7, as the 3D printed ones I tried just didn't work well, and I tried several.
You'll also need these new connectors, they're cheap and you can also replace the crappy one on the other end of the Bowden tube while you're at it.
After removing the grub screw on the old extruder gear, use some heat, like a heat gun or a hair dryer, to help you pull off the old extruder feeding gear. Trust me, it's worth it. This new one is million times better. No skipping, no jams, no underextrusion. I suffered with that problem for ever! It all came down to cheap parts.
You should re-callibrate your e-steps, as it's honestly super easy. I think 100 was the number I used. The default is 92, so if you don't want to it won't be that far off.
Edit: /u/Karzdan, this will 100% fix your issue. My print quality really improved, this small upgrade made a huge, huge difference for me. This new spring is much stronger, and the new teeth really grip the filament.
Honestly this is the route I'd go.
I printed my own extruder, and it worked great for a while, but I think I set the infill too low. Next thing I know, I was having underextrusion again due to low spring tension. I haven't found an arm/extruder on Thingiverse yet that has adjustable extrusion, so I picked up one that did.
This is the one I used. I'm pretty happy with it, because it was really easy to adjust. Almost too easy.
I bought this one when mine broke awhile back.
For the money I think I'd rather have the metal one.
I went all metal...

Make sure you get the correct handed version for your setup, right or left.
I’ve been considering the z-axis stabilizer upgrade. But I’m not really having the issues that warrant it. Maybe I’m not pushing it speed wise enough.
Is the mk8 upgrade you are doing like this one here?

I kinda like the idea of printing parts for it on itself. Or maybe for a second bigger printer at some point.
