Have been experiencing a real bad shimmy in the front steering of our troopy, usually around 80-90kph. Its especially bad when towing and up hills, figured maybe coz less weight on front?

Have had the wheels balanced but no difference.

Today I decided to check the king pin bearings. So I disconnected both drag links and felt the smoothness of the movement in the hubs. They were very notchy.

After stripping the hub to investigate I found both the king pin bearings and the CV joints were very notchy.

I'm really hoping that if I fix this this will be the route of the shimmy in the steering. Any ideas?

Also I rebuilt the hubs about 40k ago with new bearings, seals and CV joints.
We shipped this car and travelled around the world. On the road we had an issue with the spindle needle bearing, it disintegrated and sent metal through the hub. We had it apart on the side of the road many times trying to sort the issue I'm guessing this has caused the premature failure of the CV and King pin bearings. Particularly because cleaning out the hub and relubricating everything properly was a challenge whilst on the road. We were in the middle of the Pamir mountain range in Tajikistan when it happened!
