If you're still looking for clunks, also check anti-roll bar bushes (front and rear both seem to wear out), and tailshaft centre bearing is very common too. Lower rear bushing on the front control arms have worn out quickly for me, so double check even if you changed it not so long ago. They are heavy things so seem to work all the suspension bushings pretty hard in general.
Why? No one I’ve seen has ever done this when replacing it from all the UK forums. The splines are very specific and the wheel will be in the same identical position it was before you removed the component and replace it. If the wheel isn’t in the same position you need to reposition the shaft else your wheel won’t be pointing straight ahead.
