I show how to tear down, clean, lubricate and rebuild Suntour XCT (SF8-XCT-V2) forks/shocks. Periodic maintenance will help prolong the life of the fork and maintain performance. Basic service to keep your suspension working and from becoming stiff or frozen. This bike is a Raleigh Mojave 4.0. The XCT fork models have varied over the years. I believe this fork is a SF8-XCT-V2 from 2008.

* Use grease made for forks. I use Slickoleum which is also sold under the name Slick Honey. You can also use SRAM Butter or Judy Butter. If the fork uses oil, use the proper fork oil. Use of a grease/oil not made specifically for forks can damage the plastic/polyurethane parts, or otherwise leave the fork not working properly.

I've been watching RJ's videos for a while now and, although I appreciate the information he provides (he's awesome), I always look forward to see what beverages he has on the background :)

@adventure_hannah3841 2 years ago

Thanks so much! This is what's on my bike. The fork still works great, but I'm wanting to fix it up since it's 10 years old and has never been serviced.
