Some 2005-06 5.7-liter Jeep Grand Cherokees and 2006 3.0-liter Jeep Commanders built prior to Oct. 29, 2005, may produce a whining sound from the power steering system on first startup in the morning. According to Chrysler, the noise is most apparent when temperatures are below freezing, increases in intensity the colder the temperature gets and usually dissipates fairly quickly as the engine warms. Insufficient fluid flow through the power steering system is the most likely cause of the whining sound. Installing a new-design power steering reservoir, Part No. 52124317AA, should eliminate the noise immediately. Be aware that the new reservoir looks identical to the old one on the outside, but has internal design changes that promote better fluid flow through the system in colder temperatures.
