Diagram for removing of steering column for 1988 gmc 2500 pickup 3/4 ton

Check harness connections and fuses. Make sure fuse box connections and grounds are secure

You are better off taking it out from the inside of the steering column after removing the steering wheel. When the cylinder is rotated it moves a shaft that travels down the inside of the steering column that activates the ignition. There are on wires attached to the cylinder that will give you ignition. If you must drill it out you will need at least a 1/2 ins to 3/4 ins drill and that will butcher it.

Hi Darren,here's a link on your steering column removal,join the A.Z.site,become a member,it's free then you can use there repair guides,I use them alot,need more help,let me know.

a lot of comments with no answer to the question. you need the steering wheel puller tool. take off the nut holding down the wheel and use the "Teering wheel puller" (peice of metal with 3 bolts) 2 bolts mount to the steering wheel to pull, and one bolt pushes on the rod that the nut was screwed on. that bolt pushes and the other 2 pull the steering wheel off.

he ignition switch is mounted on top of the steering column about halfway between your feet and your knees when sitting in the vehicle. You will need to remove the panel beneath the steering column, and lower the column to gain access. Two components share the same mounting screw more or less. The bright light switch which has three wires will need to be removed first, then the ignition switch with many wires of bigger size.

Place the multifunction lever in the center or the OFF position.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component.
