Right guys, I've got a slight knock on my nearside front suspension, and after to serious thought, I've decided to keep it for a few more years, since it's running great, and has done me proud in the last 10 years!

Anyways,I'm looking at changing the complete set of front arms, and looking at the complete kits on ebay. My car is on an X plate, 2000 115 PD with Engine code ATJ, does anyone know how I can check what size the balljoint part is on the lower arms?

I've had problems in the past sourcing the correct CV's for this car, so it's not ideal.
