Squeak Sound When Turning Steering Wheel

A squeak sound may be heard from the steering system when making turns in either direction on some 2017-2022 Bolt EV and 2022 Bolt EUV models. The sound may be caused by contact between the steering gear pinion shaft and the plastic top cap housing on the steering gear. (Fig. 15)

To confirm the contact as the source of the squeak sound, disconnect the intermediate shaft, remove the intermediate shaft inner boot and observe the contact. (Fig. 16) If contact between the pinion shaft and plastic top cap housing is verified, lubricate the area of contact with GM Super Lube. Be sure to apply the lubricant to the inner area of the plastic top cap.

If there is not any contact observed between the pinion shaft and the plastic top cap, follow the diagnostics in the appropriate Service Information.

Refer to Bulletin #21-NA-213 for additional information and part numbers.
