Hi, not done track rod ends myself - but I get the impression that you push the ball joint out of the steering knuckle and then count how many turns to undo the track rod arm, put the new one back on the same number of turns then take it to get its tracking done. Does that sound about right? As for shockers, JodT5 has put together a maintenance page which has a link on this: Glad to hear the CV change went well. Cheers, Pete
