Strange how these little noises drive you nuts! It was all done by feel with zero visibility, I didn’t remove the dash. I could just about get my arm up inside and simulate the rattle by wiggling the end of the rack. So a combination of pushing and stressing the outer tube and a little tight fitting plastic sleeve over the portion of protruding rack. A better plan may have been to attempt to strip and grease it. However these noise are so often transient and all is quiet at the moment.
