Went to change my power steering lines and after popping out the seals a cap with what looks to be a spring inside fell out. I didn't get to see which one it fell from also which way it goes. Is this piece replaceable if it was damaged. Thanks

 

what vehicle? and maybe a picture?

 

It's a 2002 trailblazer ls it's right behind the power steering lines inside the rack and pinion ports. I couldn't upload a picture but it's right behind the seals there's only one, i just don't know which one it goes in or which way
