Steering Shake.

[Clunk]

Pull a shim from the king pin sides either top or bottom, one each side and re tighten. See if that fixes the issue..
If it does then bearings need doing but just remeber where the shims go for when you re install..

You could also try tightening the steering box.
On the top you'll see a nut and thread. Crack the nut and tighten the thread a little then re tighten the nut.
Don't wind in to much or it will bind up

When taking shims out, aren't you supposed to remove from top and bottom?
