Question aimed at the professionals really but any ideas welcomed please - I am tidying a 2004 Mini Cooper up to sell. Took it for it's mot yesterday and it passed with an advisory for the nearside track rod end having slight wear. As I'm selling it I bought the part intending to replace it which hopefully will satisfy any prospective buyer. Come to change it and the tracking adjusting nut that locks the outer arm to the inner is locked solid - have left it overnight with penetrating oil on - but no luck this morning. Because of the close proximity of stuff it is not possible to apply heat which was my next move and also considered removing the inner tie rod arm from the steering rack and removing the whole assembly but access to the inner nut is very limited.
So any suggestions would be appreciated - other than leave it as it is and give the buyer the part
