Fitting steering arm and track rod end

if your fitting the arm the track rod screws on to then yes its not a diy/at home job!!!

there are no spanner flats on the ball joint end of the arm - theres actually a special tool to remove the arm....
 
Do you know what its called? Unscrewing from the rod end looks easy enough. Ive found the ball joint bit, that has a little blue plastic ring on one end which spins round.
