    Rear End Creaking Sound

    Gentlemen,

    Creaking sound starts at 5-7 mph, 2-4 creaks on take off in D and R.
    It's getting louder and more frequent at a higher speed 20-25 mph.
    Sounds like wood creaking on an old boat or wooden floor.
    It does NOT sound dull as in front end clunking metal.
    it creaks as an after math of placing stress/load on rear end (D and/or R)

    Diagnostics:
    A local mechanic claims the 19mm wheel lugs sinking too deep causing it to creak on take off.
    Replaced all 20 Lugs with 22mm on stock 20' wheels; he was wrong!
    The sound still coming out of both sides, a bit louder on passenger side.
    After reading a post on this forum, I've asked him to retorque axle nuts, both were solid.

    Anyone had a similar experience with creaking sounds?

    Thanks

    No but make sure the sub frame isn’t cracked. A fairly common problem on the early years.

    Thanks Tdola

    Got me rethinking my previous post (front/rear suspension)
    I thought upgrading sway bars to fix fishtailing.


    Thanks again.

    Went back to mechanic,
    1. On visual inspection no signs of subframe cracks, no worn out bushings.
    2. He thinks dust/sand/harsh climate/heat, a common dryness problem,
    3. He recommends washing undercarriage with DEISEL !

    Make sense ?

    Bumping the thread, hoping one expert comes up with a suggestion.

    Update:
    1. Washed under carriage with soup and water,
    No signs of subframe cracks.

    1. Replaced rear shocks and 2 upper mounts (Mopar)
    2. Sprayed white grease at most if not all bushings.
    3. Retorqued the Axle nuts.

    I am running out of ideas as the creaking sound persists,
    it creaks the second it rolls (in D&R) still between 5-7 mph.

    Thanks

    This may not be super helpful, but since you are able to get it on a lift. Does it make the noise when you rotate the wheels while on the lift? It sounds driveline related since you said low speeds. The suspension does not care as much what speed you are going. If it was suspension related you would be able to hear it at faster speeds. I would check the driveshaft couplers and center support for the driveshaft. Bearings under stress can creak, also there is a lot of rubber in relation to the driveshaft that can wear out.

    Thank you for your kindness J2hlabs
    I will let them check for noise while on the lift,
    as well as driveshaft couplers and center support.

    Note:
    Your ruling out suspension does make sense.
    Because after washing under body, noise disappeared when driven while still wet.
    then Soaking suspension/bushings with white grease today did NOT eliminate the noise!

    Thanks again

    Creaking like that description makes me think of driveshaft area, center support or either end couplers... Definitely give em a check.

    also check the u-joints, never heard of those failing on chargers, but I have on the Mercedes platform in general and with your environment who knows.

    I do appreciate your input, I'll check the entire drivetrain.

    Thanks again!
