Involved Region or Country North America
Condition Some customers may comment of a squeak, creak, itch, or rubber type noise heard from the IP dash or center console area. The noise may be duplicated by the following:

  • Driving over bumps (noise may go away if coasting or if transmission is shifted into “N”)
  • During acceleration
  • Brake torqueing in drive (noise may not occur when brake torqueing in reverse)
Cause This noise could be caused by the engine harness rubbing on the floor pan above the transmission (item numbers 4 and 5), as shown below. The photos below were taken from under the vehicle looking up along the driver’s side of the transmission bell housing.

Callout 1 – Bank 1 Sensor 1 O2 sensor

Callout 2 – Bank 1 Catalytic Converter

Callout 3 – Front Driveshaft (on 4WD vehicles)

Callout 4 – Engine Harness rubbing on floor pan

Callout 5 – Engine Harness pushed aside to show the contact on the floor pan

Correction:

Reposition and secure the engine harness down beside the fuel/evap lines so it no longer contacts the floor pan, as shown below. The rear transmission crossmember may need to be removed so that the transmission can be slightly lowered to gain access to the area. To allow enough slack in the engine harness to reposition it down beside the fuel/evap lines, it needs to be moved/repositioned forward in the clips at the rear of the harness above the rear of the transmission/transfer case. First, release the rear harness clips and move/reposition the harness forward in the clips, then lock the clips closed. This will create enough slack in the harness to reposition and secure the harness down beside the fuel/evap lines, as shown below.

secure the harness down beside the fuel/evap lines
