    Today, noticed a squeaking noise in the rear end. It sounds like rubber moving around, but I have no idea. It happens while moving slowly in reverse, and when accelerating at higher speeds. There is no vibration or anything else..... Just a god awful sound coming from the back.

    Someone mentioned a CV arm to me - Just wondered what you guys thought!

    This Bulletin is being revised to add the 2012 model year. Please discard Corporate Bulletin Number 06-03-09-004C (Section 03 – Suspension)
    .

    Condition:
    Some customers may comment about a Squeak Noise coming from the Rear of the Vehicle. During normal 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 leaf springs, the frequency and severity of this noise will be affected by the roads that the vehicle is driven on.


    Cause:

    This condition may be due to debris getting between the leaf springs.


    Correction:

    To correct this condition, lubricate the rear leaf springs using the following procedure.

    Important:
    It has been found that the application of grease to the rear leaf springs does a better job of preventing the noise from reoccurring than replacement of the spring.



    1. Raise the vehicle on a frame lift-type hoist.

    2. Inspect the springs for damage. If none is found, proceed to the next step.

    3. Pressure wash the rear leaf springs to remove as much dirt and grit as possible.

    4. Dry the springs with compressed air.

    5. Apply a liberal amount of grease, P/N♦12345996 (in Canada, use P/N♦10953501), both underneath and on top of the front and rear tip inserts for the #2 and #3 leaves. A screwdriver can be used to gently pry up the tip insert; however, a rag around the screwdriver must be used to prevent damage to the spring. Use a flat-bladed tool, such as a gasket scraper to properly distribute the grease.

    6. Lower the vehicle to the ground and test drive to verify the repair.

    *****Please inform the customer that this will offer relief, but is not a lifetime repair. Periodic cleanings and grease re-application may be necessary throughout the life of the vehicle.
