Not regularly as such but it's not a fit and forget item no matter what Gripper says. Even so, the tighter you set it up to start with the quicker it will wear. With the track setup I've currently got I'm looking for about 15k miles which it'll take me 3 years. By that time the gearbox wil probably go so I'd have to drop the box anyway lol. But it also depends how you drive it. If you are doing lots of cruising mileage I would expect it to last far more than that!
