Greetings!

My sister told me that her front suspension fork is rocking from side to side and when I checked it out the fork has quite a bit of side to side movement where the stanchions enter lowers. Does anyone know what is the cause of this movement and how to fix it.

Thanks

    What forks are they?

    Sounds to me like cheap Suntours,that's one of the reasons I replaced with RS.

    They are just cheap forks. They are only £40 new. That’s cheaper than a decent set of rigid forks.
    I’d consider buying a good suitable second hand fork and swapping them over.

    There was a recall for a certain batch of the M3030 forks in the USA and Canada around 2015 for a defect where the front wheel came off and some reportedly 'minor injuries' caused.

    Another good reason to ditch them for something better.
