    Use rear axle hub bearings for caster steering axle.
    I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

    Hi nonoise
    Do you have a bearing number?
    Thanks

    If you can replace them without nicking your fork and screwing up your caster swivel, you are a more-skilled person than I.

    The fork assembly was corroded in place. I had to beat it out with a hammer. I just replaced the entire fork assembly. I guess one of these days I'll try to get the bearings out of the old fork assembly. But I'm not optimistic. Interesting comment about the swivel. The original fork assembly lasted 4 years before acting up whereas the new one lasted only several months. I just spray PB blaster into the bearings and adjust the nut to restore the swivel. But I was really expecting more life than several months.

    The bearings can have a significant amount of corrosion without affecting caster swivel. What I was referring to is nicking the aluminum housing surrounding the bearing where it faces the dust cap. One small nick, and a smooth swivel may be impossible.

    Does a purpose built bearing puller make the job easier?

    Hi August

    I've replaced bearings on many a fork assembly but never on a Tilite! I'm curious as to what the alan key set screw on back side is all about? Also, any info/advice for this job much appreciated

    The allen screw is to keep the stem (red circle in the figure) attached to the caster tube. TiLite says not to adjust it. Don't know why. I never had a need to and have always left it alone.
