Squeak or chirp noise in 2wd gone in 4wd. Under further investigation by engineering
Some customers may comment on a squeak or chirp noise in 2wd that goes away in 4wd. Some people may
also describe it as a metallic jingle, ringing, click or tick. Condition is easiest to duplicate in
warmer ambient temperatures, after approximately 30 miles of driving and is barely audible.
Technician may notice that the noise seems to be from the front left axle seal area. This
information only applies to the SU4 axle in pick up applications AND all utilities.
This condition does not affect durability and or operation of the vehicle but may be annoying to
some customers. Test drive the vehicle and confirm the noise is in fact as described above and
inform the customer that as soon as a repair is validated this document will be updated
communicating that repair to the dealer.
Warranty Information
For vehicles repaired under the Powertrain coverage, use the following labor operation. Reference
the Applicable Warranties section of Investigate Vehicle History (IVH) for coverage information.
