You can check the disc thickness with a mike of dial caliper and if this is the case it will be easily measured---new discs are the only fix
I'll have to see if I can borrow a dial caliper, not something in my tool box... I was thinking about replacing the stock discs with something larger, maybe the Wildwood set-up, This might be a good excuse to do it sooner rather than later...

Any-thoughts on whether there could be a problem in the steering column or rack/pinion?
