If you are just changing from a 36t to a 54t star ratchet no tools are needed.
All you need to do is pull off the End piece (its just a press fit), then pull off the cassette and freehub together.

 

sweet ty for the quick reply

 

you ought to have a cassette lockring tool and chain whip in your toolkit, though.

 

Always make sure to carry extra freehub grease in your backpack just in case you needs a little trail side freehub service.

 

I just outfitted our bikes with 350's. What happens if they get low on grease suddenly while riding?

 

Correct, if the cassette is still mounted to the freehub then the end cap is retained by the lock ring on the cassette. As said, just stick your hand behind the big ring on the cassette and lift, the whole assembly will come off. There are 2 star ratchets and 2 springs and a spacer that rides on the internal axle tube.

Re-assembly is the opposite of taking it apart. You will need to make sure to press the endcap back down fully and seat it.

 

Unless you hold your bike in a creek for an extended period of time, they won't suddenly go low.

You'll notice the ratcheting sound getting louder. I put a very small dab of mine twice a year. Buy the DT stuff. Less is more; too much will prevent the teeth from engaging properly. I've used chain lube to break down Park Polylube to the consistency of the DT Swiss grease, but prefer the DT product when I have it. One little tub will last the rest of your life.

 

That's what I thought. I have two of those little tubs and didn't want to have to put one in my pack for some odd reason and end up losing it.

 

My personal opinion about lubricating any freehub is not so much the brand of grease (which is re-branded), is to stick with a specific freehub grease or oil. Star ratchets are a little more sensitive to the thicker lubes. Thin is good. For my DT 350's, I use Dumonde Tech Freehub grease. A small amount does the trick. They're so easy to service, you can could do it every month if really necessary. Perhaps the easiest freehub to service.

 

Every wheelset I own is based off of a DT Swiss hub system. In the 5 years I have been riding I have only went thru my 5 bikes once a year in regards to the rear hubs. I pull them, clean them, use the DT Swiss grease and as said wipe a small dab on all of the contact spots and put it back together.

The only negative to old grease is the hubs get louder when free wheeling, otherwise they will be just fine.

 

coming from a hope pro 4 hub, i dont mind the loudness
