So following Broxhead I had to find out what happened to the 4WD. The main culprit is likely to be the CV joint so I stripped down the hub.
And here is an "exploded" CV
Compared to a whole one.
I was also not happy with the brakes. Here are the front pads...
One is very rusty and one has a strange wear pattern.
The disk is not much better.
Any ideas where to look???
