).
Condition
Some customers may comment on a squawk, creak or itch type noise coming from the front suspension of the vehicle that may be more noticeable in
cold temperatures. This noise will most likely be heard during small to medium suspension travel. The noise may occur with the vehicle traveling straight
and/or during turns.
Cause
The cause of this condition at cold weather conditions may be due to the inside diameter of the front strut jounce bumper rubbing against the piston rod
of the strut, creating a slip-stick condition.
Correction
1. Identify the noise at the upper strut mount area. The concern may be on both sides of the vehicle.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
Important
Take care not to damage the dust boot or mount cup during removal.
3. Pull the dust boot/jounce bumper assembly out of the strut mount jounce cup (1).
4. Slide the dust tube/jounce bumper assembly down to expose the top portion of the piston rod (1). A long screwdriver or pry bar may be required to
pop the dust boot/jounce bumper assembly from the mount cup.
5. Apply grease, GM P/N 12345579 (in Canada, 10953481), around the circumference of the piston rod ONLY in the exposed area (to top 25 mm (1
in) of the piston rod, measured from bottom of mount cup).
6. Raise the dust tube/jounce bumper assembly up to the mount cup.
7. Rotate the dust tube/jounce bumper assembly on the piston rod to ensure grease is distributed around the rod.
8. Re-seat the dust tube/jounce bumper assembly into the mount cup.
Note
After installing the dust tube/jounce bumper, the vehicle should be driven over a road surface that will input sufficient jounce travel into the
suspension, which will aid the dust tube/jounce bumper assembly into the mount cup (speed bump, driveway entrance, or other bump).
