The 'track rod ends' ordered from Jeepchryslerparts midday Friday arrived the next day (saturday), that's phenomenal delivery performance and well worth praising. Anyway fitted them fairly easily, and put it in for a retest this afternoon. Lo and behold I now have a 12 month MoT on her, so she lives for another year .
4 tyres are going on Saturday, and then a re-tracking, and that should be good enough for another 12 mts/10,000 miles.
For those old/interested enough to remember Faulty Towers, I have similar relationship with my GV to what Basil had with his 1100 whereby it's been threatened and clearly knows that if it seriously misbehaves, it'll be send to the big scrapyard in the sky .
