Power steering troubleshooting

[GT6k]

So my power steering went intermittent for a couple of journeys (would work once warmed up) but has now gone completely. There's plenty of fluid in the reservoir and i have tried the bleeding procedure as per the manual. What next, how do I determine whether it is the dreaded key way or the dreaded rack ?

The coupling is rotating with the engine OK, the rack feels very stiff it just doesn't want to move. I have also checked out UKKids idea of kitty litter in the UJs and although there was some there it wasn't interfering. with the movement. I think i will get the steering shaft out first and check the UJs.

YAY - top UJ seized solid, that was easy.
Now where is that alternative parts list.

Unfortunately the late summer Harewood falls on my sons birthday and he will insist on parties etc rather than watching me scoot around the track. I have an entry in for Shelsley though, so crossed fingers for that.
