    Hey guys! New here, so I'll start out by telling you I have a 2010 Silverado, 5.3 4x4. Reg cab....... My baby.

    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!

    If its the rear it isn't a CV arm.... There aren't any... It may be a brushing that has dry rotted or became misaligned. If I were you I would look over all the rear suspension brushings. and poke at them seeing how soft they are and make make sure they are not cracking or crumbling.

    I knew the CV arm thing sounded off....

    I don't think it's a suspension thing though.... It sounds like a rotating thing, and linked to how fast I'm going, and if accelerating or not.

    If it helps - I JUST had an oil change done. It's just funny I have it in the shop, and it comes out with this new problem. The truck is only 2.5 years old!

    Would it be a U-joint???

    It may be a U-joint. May be a bearing or seal. The only way to tell will still be feeling around the rear end of that truck. Check everything for extra play, dry rot, cracking, improper lubrication and just plain looking out of place.

    Check the u-joints and the fluid level in the rearend. It could be the rear brakes or the parking brake shoes inside the rear disc/drum.

    I got under there - I reefed on the driveshaft both in and out of N - the U-joints are good and solid. Greased all the fittings I could find, and all the bushings and shackles are fine. It has to be something inside the wheel I guess.

    Bugging the hell out of me. I just had it into the shop for an oil change, fluids and inspection. That was Thursday.

    [MENTION=59606]geo1[/MENTION] he should still check the parking brake. Even if he doesn't use it it may cause a problem. Also its a smart idea to use your parking brake it removes strain from the tranny and makes sure that if your vehicle is improperly towed or attempted to be stolen from you the transmission wont be ruined if they try to drag it from the front.

    .

    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.

    Good call @99'HEARTBEAT ! My 02 silverado had a squeak in the rear when hitting bumps. I noticed it after traveling down a dirt road. I pressure washed the leaf springs and sprayed the crap out of them with lubricant. The squeak went away for a while, whenever it would return I just resprayed them.
