Subject:
Noise When Turning Steering Wheel
ATTENTION:
Service Manager/Service Technician
Models Affected:
All 4, 6 and 8 cylinder vehicles with air bag (M562) option.
Concern:
Scraping or squeaking noise from steering wheel or switch assembly.
General Information:
If noise is heard from the steering column area, it may be caused by a combination switch assembly that is not adjusted properly or by a machining burr on the base of the splined shaft of the steering column.
Repair Information:
Step 1: Note radio security code and station presets, then disconnect the battery.
NOTE:
To avoid setting an air bag fault for ignition pill # 1, DO NOT turn the ignition key to the "on" position while the steering wheel air bag is removed.
Step 2:
Make sure steering wheel is centered and wheels are straight ahead.
Step 3:
Remove air bag from steering wheel and remove steering wheel and contact unit.
Step 4:
Inspect the base of the spline for any burrs and remove any burrs with a key file or suitable tool. (A burr in this area may cause the turn signal cancelling ring to bind slightly inside the contact reel.) Figures 1A, 1B and 1C show the area where burrs are possible.
Step 5:
Measure the distance from the top of the steering shaft to the base of the switch housing. The dimension should be as shown in Figures 2A, 2B or 2C. If the dimension is not within specification, loosen the switch assembly, adjust to specification and retighten.
Step 6:
Inspect the horn ring on the contact unit for grease or damage and clean with acetone or suitable cleaner.
Step 7:
Inspect the horn ring wiper contact on the steering wheel for damage or any trace of lubricant. If the wiper contact has had lubricant on it or is damaged, it must be replaced. (Due to the composition of the wiper contact it is not possible to clean it) No lubrication should be used on the contact unit or horn wiper contact.
Step 8:
Reinstall contact unit and steering wheel. Be sure to install in the same position as prior to disassembly. Reinstall air bag using new bolts and torque to 1O N-m.
Step 9:
Reconnect battery, recode radio and perform a system adaption, if applicable.
