Well there ya go! I didn't think of that. Just remove the retaining ring and tap the new one over the old, then replace the retaining clip. Thanks Kevin, I'll check it out. Thing is, this chatter noise maybe coming from inside the old upper bearing and I've had a gut full of it in my ear, so I'll definitely remove it if that's the case.
Yeah I know what you mean "It's a pretty big job" in removing the shaft. The whole fan plenum assembly, uni joints, lower bearing, steering wheel and binnacle etc etc - about 6 hours there and back (for me).
The tie rods are good but I will do the rack. Thanks for the tip.
