Grant Part #61036 - Revolution - Manual (Page 3)

2. Remove the horn switch assembly by loosening the 4 T-30 Torx screws (numbers 1 and 4) holding
the contact plates to the steering wheel and remove this entire mechanism (2) from the wheel. Note
orientation (wires at the top of the switch mechanism) so you do not reinstall upside down. See
Illustration 4 above.
3. Disconnect the wheel switch wiring harness at the column connector. Do not pull excessively on
the connector or clockspring mechanism and do not turn the clockspring now or at any time
during the remainder of the installation.
4. Remove the steering wheel retainer nut and mark the shaft and wheel for alignment.
5. Remove the steering wheel by using the GM J1859-A puller with the
J-36541-A adapter and J42578 puller legs. Or an equivalent 2 jaw
bearing type puller (see illustration).
6. Remove the rear plastic shroud by removing the 2 T-20 Torx screws in the back of the wheel.
7. Loosen the wiring harness from around the hub of the wheel to get enough slack to remove the
switches. Push each switch out of the wheel slightly by inserting a narrow flat blade or Phillips
screwdriver into the rear hole in each spoke and push the switch out the front of the wheel. Push
slowly and evenly and do not stab at the switch or you may damage it. When the switch is clear of
the wheel disconnect the wiring harness from it and remove the switch.
8. Remove the switch wiring harness from the original wheel by pulling the switch connectors back
through the hole in each spoke and removing the plastic clip from the wheel center.
PREPARING NEW WHEEL FOR INSTALLATION
1. Reinstall the switch wiring harness from step 8 above in the same orientation as it came out.
2. Reinstall the plastic shroud with the screws previously removed in step 5 above.
4. Push the leads from the wiring harness up through the hole in each spoke so the plug end that goes
onto each switch is protruding out of the switch hole in the front of the wheel.
5. Connect the wiring to each switch and push the switch back into the new wheel in the same location
as the old wheel. Take up the slack in the wiring by pulling it back through the access hole while
pushing the switches in.
INSTALLING NEW STEERING WHEEL
1. Position the new wheel onto the shaft orienting it to the mark made earlier. (Reference wheel
removal step number 4 above).
2. Install the steering wheel retainer nut and torque to 40 N-m (29 lb ft).
3. Reinstall the horn plunger into the plastic tube by pushing down until the stop and rotating 90° to the
right to lock it into position.
4. Reinstall the horn switch assembly by positioning onto wheel and tightening the 4 Torx screws
securely (make sure wires are at the “top” of the switch mechanism).
5. Position the airbag module near the wheel and connect the electrical connectors to the module.
6. Connect the connector-position assurance (CPA) clips into the electrical connectors. Seat and lock
the connections.
