Here is the short version....
Start by removing the cover that is under the column....held on by two screws (yellow arrows)
Then removed the larger bracket that is now exposed...held on by 4 bolts (green arrow)
With that part removed, you should be able to see a metal strap that curves under the actual column, holding it up. That strap is held in by two bolts. Loosen the left one and remove the right one. This will allow the column to hang in place for a moment without falling while you take care of the under-hood portion.
Now, go under the hood and remove the intermediate shaft (not required in all cases) It is the shaft that I have indicated. It is secured by a clamp-type fastener at the top and two bolts at the gearbox.
You must COMPLETELY REMOVE the bolt in the upper fastener before it will come off.
And depending on how rusty it is, you might have to use a hammer and some lube to get the upper portion off the splined steering column shaft.
NOTE- SINCE THIS PART IS SPLINED, MARK IT WITH SOMETHING SO YOU CAN LINE IT UP CORRECTLY WHEN RE-INSTALLING!!!!!
Next, you will notice that the intermediate shaft is made up of two parts....one goes inside the other. They have a pair of pins that hold them together. You simply drill those pins out slightly larger than their actual size, then spray some lube in any opening you can find, and push them together....making the unit shorter.
NOTE - THIS MAY REQUIRE A HAMMER AND A VICE AND A BUDDY AND A CAN OF PATIENCE!
Now, get back under the hood and loosen the clamp that holds the column to the firewall bracket. Notice, it is the clamp that surrounds the column and secures it to the firewall bracket. Do not remove the bolts that secure the bracket to the firewall.
Now you are ready to start moving the column.
Remember the bracket that you loosened and left hanging by one bolt earlier??
Lift up on the column and rotate that bracket out from under the column...allowing the column to drop out of the dash cavity.
Or, simply finish removing the remaining bolt and remove the bracket completely.
You should see some sort of slot in the column and a tit under the dash that went into the slot....(look closely...it is there...)
Anyway, you need a new slot for the tit to line up with once you relocate the column.
So, slide the column towards the dash the amount you want, and mark the new tit location. Then using your favorite power tool, make a new slot. (I used a Dremel with a fiber cut-off wheel)
(Arrow indicates original slot. New slot is cut closer to the steering wheel)
Once you have that done, start bolting everything back in place and enjoy your new belly-room!!!
Hope that helps.
