Shock is a Fox DPS off of a Tallboy V4.
I want to perform an air can service and these guys are in the way. They spin smoothly so I don’t want to ruin them. I tried some gentle tapping and they don’t budge. Any advice, maybe that doesn’t require me purchasing some $150 Fox special tool?
Thanks!

How well assorted is your parts bin?
Basically you want something that can drive the pin out and something that supports the inner bearing race.
A long screw with a fitting nut and washers that passes through the pin, a tube that goes over the screw but fits through the bearings and another tube that fits just over the smaller tube. With those parts you can build yourself a pin remover and a tool to press it back in
IMO a press usually helps with this, I would suggest to ask if a nearby shop has anything available. The risk of damaging the bearing casing might not be worth the effort IMO. Someone who did it himself might be able to prove me wrong 😀
It’s been a long time since I did an air can service, and I’ve got everything(I think) to do one this winter. I don’t remember having to press out any bearings.
Why are these in the way?
[This guy does awesome how-to’s btw](https://www.youtube.com/@zoubtube) if you need any tips along the way.
eta: [I see](https://youtu.be/vCC5SZ-u-Gc?si=xBmAHEepU1ZfUWK8&t=47). My mounting hardware is on the air can side, not the damper side. It’s a Scott Spark with the upside down shock.
Don’t these just remove with a DU bushing tool? That’s a $30 tool that pays for itself by not ruining your bearings.
I made a rough puller by finding two large (3/4″??) washers that just fit over the narrow part of those cups. I notched them so they could just barely fit in at the narrowest spot. I put three skinny bolts in one, and matching divots in the other. You lengthen the three bolts by twisting the nuts, and the system presses on the the other washer. Fiddly AF but it’s worked a few times.
Inner axle just falls out after the bearing holders are gone.
There’s probably a better way.
