how much to replace drive shaft with new type

Hi Guys. Im looking at replacing the rear drive shaft with new type next year. I suffer the famous THUD that occurs on stop start(its very mild, happens every 3rd stop, is worse in hot weather or a long run)

I have tried greasing with the penrite moly type recommended by you guys and has improved a bit. I will try a little more to see if it helps. After reading the massive thread on this I understand there is a new type of shaft with a better design that people have installed. Any ideas on cost would be appreciated.

Thanks Rob
