Mechanics Question?

I'm also uncomfortable doing this although I have done it in the past.
If you give a tech your part to install, and something related to that part or the part itself fails, the shop loses liability.

I bought all new suspension with the intention of doing it myself, then decided I didn't have the the time, space or the tools to do this right so I brought it to a shop. They installed everything and the alignment was a bit off so they fixed that right away and I was home free.
100 miles later and the car was pulling again. Brought it back to the shop and they couldn't align it and told me the control arms were worn out so I parked it having exhausted that years budget already. I didn't buy cheap parts so I know the shop screwed up, but what could I do except start arguing which would probably not get me anywhere.
Next year, I moved and brought it to a new shop. They told me a couple bolts weren't tightened to spec and I was all fixed up for the cost of an alignment. Lesson learned.
