Brought my self the new seals ( was feeling pretty confident at this point having decided too do them both! ).
Have spent the whole day under the car which has turned out to be a nightmare of a job. have got to the point now where i have put in the new seal after stuggling for about an hour to locate it ( the propper tools would of helped though my huge socket eventually managed too do the job. The ony trouble now that ive got is refitting the flange and getting the circlip back on. Due to the huge spring behind the flange its going to be a buggar. Im some how going to have too make myself a tool to push the flange in whilst i refit the circlip.

ill keep u all posted on my progress
