Trailer Arms

I went to Sears today and got an alignment.  The tech was saying to also replace the trailer arms that way you can get a true straight wheel. 

Any thoughts? I couldn't find anything on trailer arms when I looked that up on Google (searched Trailer Arms).

you could also try "trailing arms" but its sounds like a bunch of bs to me.

THe only reason you'd have to replace those was if you did some serioud damage to the underside of your car. Trailing arms are pretty strong, so if you managed to dmg those than you probably would have damaged a lot more.

yeah, that's what i thought.  and they aren't even broken is what that guy said.

also, i believe he wanted to readjust the camber but its not adjustable.
