Front strut assemblies replacement

What is your question?

2005 XC90 T6- I bought replacement struts (bargain pricing) and they tanked quickly and have "clicking" when turning again. I see options online for $100-$600 but wondering if someone can offer direction on what is the best option for a 14 year old car with 110K miles that my teenager will drive into the ground?..or if I should just change the caps on the existing cheapo ones? thanks
