hi, i have a escort mk6 1997 1.6 16v zetec.

right ill get to the point, my rear passenger side wheel has 1.5mm toe out, this happened when i went into a pot hole, and basically i have had a supertracker tracking test done on it and found that it must be the stub axle.
SO... how hard is this to change? can somebody please give me a walkthrough? im really lost with this one and its really annoying driving down a road with having to hold the steering wheel in the turning left position. please help.

thankyou!
