I have an old GT i-drive 3.0 from like 2001, it has a Judy Rockshox fork on the front. I imagine its never been serviced (I bought it used) and it's starting to sound like a symphony of rusty trampoline springs. It's so noisy you could hear me coming from a mile away (riding on single-track mountain trails).
Any ideas what might cause a front suspension to make such racket? Is there anything I can do to make it stop? Like is this a DYI project or is it time to visit the mechanic?
