Purchased the car in early sept 09, thought banging was just a trait of the SRI suspension setup.
How wrong can you be?????

Recently replaced rear discs and pads, rubbish handbrake was driving me nuts, whilst stripped down I noticed a splayed bush on top of hub(you guessed- rear control arm) b****r.

Thought to myself, why should I pay for replacing the arms(o/s a lot worse than n/s). Anyway, called dealer I purchased car from, after a lot of tooing and froing they agreed to replace both sides under warranty- RESULT

One very happy SRI owner

I will not name dealership but do wish to extend my gratitude to those who sorted it for me.
