Hey everyone. This is my first post so please bear with me.

I ride a 10 yr old Bontrager Racelite hardtail with Judy XC fork (also 10yrs). Fork is stock. Never had any issues with it until last winter when I went up to Colorado for a few months, and the fork compressed and stayed like that. No rebound or compression, nada, just stuck at the bottom. Adjusters (+/-) stuck as well. Thought maybe it was from the altitude and cold.

Can someone explain how to service and set it up correctly (oil type, air pressure, parts available/interchangeable, etc). I think the crown had to be swapped from the original Judy to a Bontrager(black) one to fit the stem. A guy at a shop today told me its a 1" threaded (I think) and that parts are long gone, and that I should try adding some air.

Any advice greatly appreciated.

The Judy forks used MCU elastomer material as springs, and it sounds like they've turned to goo. You'll need to remove the top caps to inspect them.

Replacements are not available anymore from Rock Shox, but you might be able to locate some replacement steel coil springs or Eko sport air cartridges, but the cost may exceed what the fork is worth.

Here's the service manual for that generation of Judy:
