I have taken my steering column out to check it all over as it was playing up the other day it all seems ok but might change it or possibly replace the tube it all sits in as I currently have one that the PO has fabricated plus I could do with a new indicator stalk ring with housing as some bolt holes in mine are stripped also the ring that goes on the steering wheel ;-)up
Got to check my steering box too again seems ok but not sure if leaking oil ???
