Sir, I would not unbolt the lengthy steering column from its box. Why? Now you be into disassembly of the steering worm gear and its innards, which is subject to the loss of lots of bearing balls and quite complicated. If it works fine, leave it alone. Why do I know? Previous owner on mine took it apart to trailer it and I ended up using another one from a doner vehicle. My opinion. Thanks Karl. V/R, Nick Cavallaro, Bel Air, MD
