Seat Belt Sticky--Easy To Replace?

[Emperor Penguin]

The title speaks for itself.  After about twenty-three years my driver's seat belt does not retract well.  Is the repair easy enough I can do it myself, or complicated that I should take it to a shop and have them do it?  I have a 1995 LS 400.

Maybe you can ry cleaning them. This is a common issue as these cars age. Mines are weak as well.
