Not necessary if you just want to change the stalk. Grab it and pull straight out toward the outside mirror. Even if you have cruise, you can still remove the stalk and cruise wire by unhooking the wire under the column and pulling the stalk out. Don't pull the wire out but a few inches. Cut your old wire off the stalk, Tie your new wire on to the old one, and use the old wire to pull the new wire down the column. Then just push the new stalk in. At least that's how it's supposed to work.

Unless of course 88's are different from 84s.
From Oliver Sholtz:
"The prime suspect if your cruise control is non-operative is the cruise control stalk. The switches in the head module go into the one wire that runs down the steering column. You don't need a special tool to check it. Just disconnect the connector at the steering column and plug in a known good switch. This one can be from almost any GM car from the eighties, I use a switch from a Fiero with the wiper-washer portion broken. Plug it into the harness and go for a test drive. If the cruise works now, you need a new stalk. Since the connector is already disconnected, tie some cable to it and yank the stalk straight out of the steering column. Pull it all the way out and use the cable you tied to the connector to feed the new stalk's wire through the column. The new stalk easily snaps into place. Hook it up and you're all set. The original part is discontinued, but GM makes a replacement stalk that works just fine. The part number is 2511 1290."
