Had the recall work done on my 400 at.. have some concerns.....

ecm replacement seems to have waken up this machine in a serious way!

my concern though is with the tie rod ends that were replaced. I picked my machine up before work last night and was able too take a good look while at work. I swear there is small hairline cracks in these tie rod ends. they seem too run on top of them, are about a 1/4" in length. I can definitely feel what I am seeing when I run a fingernail over them. Is this a breakaway feature or should I be really really concerned at what I am seeing... going on vacation next monday and I want too take my machine.. Should I bring it back or is what I am seeing normal?
