    Cracked Swingarm/Chainstay on a Trek Scratch



    Crack on chainstay.







    Decided to replace all the bearing on my rear suspension.



    Bearing part numbers:

    Front EVO link: TPT6901VRS
    Rear EVO link: JNK6900VRS
    Front chainstay: JNK6903VRS/10
    Rear chainstay: JNK6903VRS




    Called my LBS and I had a replacement chainstay in about 1 week. It was covered by warranty. Note: The new chainstay comes with new bearings installed.

    Trek's warranty: https://www.trekbikes.com/us/en/supp...ited_warranty/



    Used a vise as a makeshift bearing press. The spacer in the rear is a cut end of a handlebar. It worked well as a backing so the bearing could be pressed out.



    A hammer, socket, and extention can be used to install/remove bearings that cannot fit in a vise well.

    Ok it has to be asked (maybe because I've got the same frame!), how did it happen?
