26mm?? something like that...
remove the driveline while the fluid is draining.
two choices, go in from the hub side...
or go in from the felt wiper side.
either one requires pulling C clip.
on the hub side, remove the locking hub assembly.
remove the wheel bearing nuts (two with mallable lock washer between them).
Remove Caliper (loosen brake line) and hang off spring or somewhere.
Pull rotor assembly, bearing should fall out, catch it.
remove seal, backing plate and spindle, note where gaskets are (two paper, have replacements ready)
Pull birf
Do other side
now remove third member, use rubber mallet to break free. Have new gasket ready.
On reassembly, seal your paper gaskets to one side only. this way, when you take it apart on the trail, your gaskets stay put.
Suggest you inspect/repack steering arm bearings. Literally remove the steering knuckle from axle end and clean it up. Also, new felt wiper and what not on inside.
You're there, you might as well tag it all.
have lots of disposable shop towels ready, parts cleaner and a long afternoon.
take care...
