    Creaking and crackling from carbon rear triangle on 2010 yeti 575

    I think the title says it all. I can't find any cracks and I have pulled apart and lubricated the bottom bracket and checked everything I can but it seems like the creaking is induced during stress on the triangle during hard pedalling when the triangle is under stress from the drivetrain. My guess is the sound is generated where the carbon meets the aluminum but i could be wrong. How the heck do I rectify this issue? The constant racket has me at my wits end. Thankful for any help!
    Keep the rubber side down

    Maybe try removing the dropouts, cleaning them, applying blue loctite and torquing to spec? Check the yeti manual for specifics. Other possible culprits could be the seat/seatpost or the bolts on your crankset.

    From my experience, also check your:

    - chainring bolts
    - Rear cassette fastener
    - Rear derailleur mounting bolt
    - pedal bearings (old Crank Bros especially).

    I've experienced significant creaking from all of these places/components. I have a 2011 575.

    My bet is the dropouts- try that first.

    I am embarrassed to ask but how would I service the actual dropouts? Pull the aluminum from the carbon seat stay then put it back in? I looked at them and it is a press fit and not sure i would assemble or disassemble. Not sure the yeti manual covers that level of maintenance but could be wrong.

    Simply remove the rear hanger and clean it and the dropouts. Apply a light coat of grease on the hanger interface with the drop out and use some blue loctite on the screws.

    DO NOT pull any aluminum anything from any carbon anything... Lol.

    +1 on "DO NOT pull any aluminum anything from any carbon anything... Lol. "

    Since you have a 2010, I believe you only have a QR derailleur hanger. It is held on by two small fastners. Looks like OS STANDARD QR HANGER WITH FASTENERS - 575 - Parts.

    The newer 575s came with two dropouts - therefore another story.

    Be sure to check what I mentioned above.

    Had a similar issue on my ASR5C and checked all of the previously mentioned suggestions without any luck. It turned out to be the shock bushings that were worn out resulting in a significant play causing it to creek when pedalling.

    make sure to grease the main pivot bearings that sit against the seat tube

    I was having a similar problem with my 2010. Ended up being as easy as tightening up the rear QR. Wish I had figured it out before I bought a new bottom bracket and pedals (thinking that they were the issue).
