Having a problem with the Saff lately, the steering has a horrible vague spot either side of centre, seems to be OK when loaded up with a bit of lock on. If I'm driving in a straight line it seems to need a lot of correction constantly.

I've changed the TCA's (poly bushed all round) and found the ball joints knackered, so i'm thinking the track rod ends may be the same. Failing that I suspect the steering column joint, but that would make the steering the same all the time surely?

The rack was replaced a few years ago and hasn't done many miles since so I'm hoping that is still OK.

Any thoughts welcome.
