3/11/09 - Busted!!
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???
