I agree with steved0x.
if you have noise at lower speeds and bumps problem is mostly no8 in the rear.
I removed the front ones first. Openend the top side – pretty dry, no grease in. Put in around 15 ml gramm grease in each side with a syringe. Turned the joint 90 degrees. Assembled them and put them back in.
(Btw. it's important to use the right torque specs if you put them back in. And i saw a video of a guy from UK who troqued the bolt and not the screw. So sometimes the DIY is causing the problems.
Make shure you have the right tools before you start.)
Put the car back on the road. Better but still noises. And from that moment i could identify that the noise was coming from the back.
So when i did my axle boots i also did an overhaul of the rear ones. In my opinion they get toasted by the engine heat. There was more grease inside, but the grease was old and hard. And the rubber was also harder. Same procedure as with the front ones.
Noise over cobblestone at lower speeds is gone.
It's a shame that modern joints can no longer be regreased easily.
