I've had this rear hub for a few years now and it's developed a problem where I'm guessing it's getting some friction built up in it because when I'm going fast and coasting the chain will start to load up above the chainstay and start to sag while the length of chain along the bottom will tighten up and stretch the rear derailleur out.

It obviously gets worse when I'm coasting and then backpedal. Also the smaller the cog, the more the problem shows up. It almost never happens in the largest cogs even if I'm going kinda fast.

The Stealth hub uses some sort of clutch packs I believe...I actually have no clue how it really works, but it's instant engagement and worked really nice before so I'd like to figure out what's wrong and how to fix it...plus it was really expensive.

Thanks.

you can take it apart , but you have to be really careful not to get any degreaser in the bearings or any kind of lint or dirt. i have had to do that to both of my stealth hubs after they were about a year old. just use a lint free rag and put some light lube on the rag. pull the freehub body off and wipe off any dirt or excess grease that is on the needle bearings. make sure that the rubber seals are clean and lube them with a light lubricant , but not a teflon based lube(it can damage the rubber over time). put it back together and it should feel noticably smoother and turn easier. there is always a little bit of drag on these hubs, but it should be better after a little cleaning.
I love my stealth hubs, if you know anybody that is looking to get rid of one , i would be interested.
