For a belt noise condition, the first check should involve a belt-to-pulley alignment check. Verify that the power steering pump pulley is pressed onto the pump shaft in the proper position. While the pulley should be flush with the end of the pump shaft, it can be repositioned on the shaft to achieve the proper belt alignment.
Vehicles produced after June 2004 have the revised AC/power steering pump mounting bracket. The rear power steering mounting bracket on all vehicles prior to and after the mentioned production date may require a modification. This modification involves drilling larger holes into the rear mounting bracket to ensure proper alignment when installing the mounting bolts. GM TSB 05-06-01-018 illustrates the proper procedure and necessary mounting bracket part number, where applicable. Chrysler acknowledges that a belt chirping or squeaking condition may be present on the 2004–2005 Pacifica with the 3.5L engine, due to misaligned pulleys.
