I have a K reg Orion 1.4 carburetor model at low speeds when turning left or right a very loud noking noise is sent through the wheel stations both cv joints have been checked and are ok. could it be a ball joint or a suspension bush

your advive would be appreciated

Your problem could well be a Ball Joint or suspension bush, but it's more likely to be the bottom steering Universal Joint, it fits at the bottom of the steering column and connects to the rack, it's quite common for them to become worn and either seize up causing very tight steering, or become loose and knock.

Find a good small garage and ask them to check it out for you, it shouldn't cost a lot, they'll probably also check the ball joints as well, it will be worth getting it checked as it sounds serious enough to fail an MOT, and could put your life in danger. Please don't take a chance get it checked as soon as you can.
