197 steering arm?

Hi,
Had a slight dealing with a curb the other day thanks to some oil..
Was turning at some crossroads and skidded into the curb. Turns out ive bent the steering arm up? Cant remember if thats what the garage said it was called.. Any ideas? Its driveable with no vibrations or shakes, just wearing the tyre down a lot quicker than normal! How much would this cost to get replaced approx if anyone has had any similar problems?

Cheers,

James
 
steering arms (steering track rod) are available as a seperate part - think they are approx £40 - an easy job if you have the right tools...
