Toyota Camry vvti 2.4 - Steering rack and power steering pump - gregray

I own a camry, 2002 model, and there is a clunking noise when setting off either pointing left or right. There is some play in the steering rack, and I would like to find out if this item should be replaced with the pump as well. I have been informed that the steering rack and the pump should be both changed together as a matter of course. It hasn't shown up during MOT's but I think it is better to have either a replacement steering rack or have it rebuilt.

Thank you for your thoughts.
