Service and Maintenance
.
Squeak Noise from Rear of Vehicle
(Lubrication of Rear Leaf Springs). During
normal driving operation, certain vehicles
may exhibit a squeaking noise that may
be traced to the rear leaf springs. While
this noise is an operating characteristic of
the leaf springs, the frequency and
severity of this noise will be affected by
the roads that the vehicle is driven on.
This condition may be caused due to
debris getting between the leaf springs or
the lubricant being washed off when a
high pressure water hose is used to clean
the vehicle. To prevent squeak noise from
the rear leaf springs, lubricate (ACDelco
lubricant - 52114822) the rear leaf springs
during normal vehicle maintenance. See
your dealer.
