TRD Strut Blown after 2 months. What's next?

[Ecefour]

A few months ago, my '07 Yaris started making a clunking noise on the passenger side front. I was at 140k miles with the OEM struts, so I decided to swap them for the TRD units. I bought the TRD struts from the Toyota dealership two months ago. I also bought nearly every part of the strut assembly (springs, bearings, strut mounts, etc). I installed them on the 19th of November and immediately started hearing a similar-sounding clunking as before. Like a complete fool, I spent hundreds of dollars throwing every possible part at this thing. New axle, lower control arm, outer tie rod, and sway bar end links. I also checked the torque on many suspension bolts, and i confirmed motor mounts weren't an issue. Everything (except for the axle) was purchased from the dealership. Still, the damn thing continued to make the noise. Finally, I decided to ask the mechanic to inspect my car. Today he called and said that the passenger side strut is blown. This is incredibly frustrating to hear. Either my mechanic is off base (I did recently undercoat my Yaris so he could be confusing the fluid film for the strut fluid). Or the strut is truly blown, and I spent copious amounts of money at the dealership and still got burned. Toyota doesn't sell the TRD struts individually, as far as I can see, so at a loss at this point. Can I get a refund from Toyota? Did I potentially screw up the installation? I'm starting college again in two weeks, and I'm almost completely broke at this point...

I still need to retrieve my car from the mechanic this afternoon. I'll ask him to confirm that it was strut fluid he saw, and not the fluid film. But really, I don't know what else can me making the noise at this point.
