Adjusting the T&T Telescoping Feature
If you rotate your telescope locking lever all the way clockwise and your column does not lock securely in position, it is possible that the lever just requires adjustment. The hollow upper steering shaft is locked and prevented from telescoping by a wedge and a rod that is inside the shaft. The rod is pushed down by a special "star" screw. The "star" screw is attached to the locking lever that is just under the horn button.
For this locking lever service procedure, it will be helpful if you rotate the steering wheel and set it so that it is in the straight ahead, down-the-road position. Also disconnect your battery.
Carefully pry the horn cap assembly from the steering wheel using a small, thin bladed screwdriver. If you merely yank on the horn cap it can be damaged. The cap assembly consists of three pieces that are all staked together. At this time, you might want to check that the three stakes are secure. You may even want to add some JB Weld to the stakes for insurance.
Unfasten the three screws that hold the upper horn contact in place and remove it along with the loose shims that are right under it.
With the horn cap removed, you will see that the telescope lever is attached to the special “star” screw with two small phillips head screws. Remove the two screws. The locking lever will be loose but trapped under the “star” screw.
You can now remove the “star” screw and check to insure that the lock rod is in place. You may need a small magnet to pull it out of the upper steering shaft. You will not be able to remove the lock wedge at this time. Reinstall the rod and the “star” screw and using a large phillips head screwdriver, rotate the “star” screw clockwise until it is tight. This should cause the telescoping feature to lock in place. Position the locking lever under the “star” screw such that the thumb tab is approximately at the 11 o’clock position. Attach the locking lever to the “star” screw with the two small screws. (The telescope lever has numerous tapped holes in it, allowing it to be attached in multiple positions.)
Try applying and releasing the telescope feature several times using the locking lever. It should telescope freely with the thumb tab on the lever at the 11 o’clock position. It should be locked securely in place when you rotate the tab to the 1 o’clock position. If it is operating correctly, replace the shims and fasten the upper horn contact in place with three screws. Note that the upper horn contact has a leg that extends down from it. The contact must be oriented so that the leg sits on the horn contact sticking through the steering wheel hub. Snap the horn cap assembly into place. Reconnect the battery.
