A word of warning - it might not be anything to do with the suspension, and instead it may be grit getting into the bash plate.
I had my upper suspension arms replaced for £768, and it made no noticeable difference to the creaking/squeaking. I argued with the service centre, who insisted that the suspension arms were creaking, but it was "masking" another thing that was creaking caused by the steering column at low speeds. I couldn't really win this argument - I had no evidence that they were wrong, and at this point they had replaced parts and expended labour.
The next day I went to a different service centre, initially to get the "intermediate shaft" replaced (ironic given that I felt I'd been intermediately shafted the day before). When I got there, thankfully the technician asked why there was such a specific request. I explained my poor experience the day before, and he seemed quite keen to investigate to make sure that what was requested was needed. He instead removed the bash plate, found loads of grit, sanded down the mating surfaces, and only charged me £90.
