Fitting the new Tie Rod
6. If you did use heat leave the stem and thread to cool down for a few minutes then use some grease spread into the NEW ball joint and thread it on till you think it's about the same distance as before, then check the correct measurement with the piece of solder from before. If it is slightly out turn it in or out till the measurement is correct (pic 7)

7. Now put the new ball joint into the steering arm and tighten the tie rod locking nut, ensure only the nut turns and not the thread so best to keep the molegrips attached at this time or the alignment can be put well out (pic 8)

8. Now tighten the ball joint nut, a light tap with a hammer will help stop the ball joint thread turn as it's being tightened. (pic 9).

9. Replace the wheel and drive to your local tyre centre to get the wheels properly aligned (don't think for one sec no matter how good your judgement was that you can skip this step).
Job done.
