Hi Steve,
I purchased the whole hub, I had it fitted by my mechanic guy, it took about an hour, he also took a look at the ball joints and the wishbones, there is a knock coming from the front some where but we cant find it.
The car has an MOT on Thursday, let's see if it goes through, it should as I have it MOTd 3 times a year and it has passed all of them with no advisories (what a car!)
You are right in saying it's was one if the first 430's in the country, it's a great car and runs on LPG as well as petrol.
Thanks..
