Are Dura Ace 7850 CL 24 Hubs Serviceable?

Ive had my Dura Ace 7850 CL 24 for about a year now, when I first bought them the free-wheeling was quiet, but now the free-wheeling is getting louder & louder, their making more ticking noise.
Not sure if there is anything wrong with them..... Are the hubs serviceable?

The hubs are very serviceable- normal cup and cone- but it sounds like the freewheel not the hub.

Noise will increase as the stock of grease in the freewheel body breaks down. If you aren't getting any slipping, and there is no roughness in the hub itself (spin the wheel with the axle held between your fingers) there is little point in taking it apart as the freewheel bodies aren't normally serviceable anyway-

You can't service Shimano free hubs - just run some oil in if getting noisy. If they start screaming then probably time to think about replacement. DA free hubs are pretty durable

As Monty points out, it's the freehub and not the hub... run some thin oil and the noise will disappear
