I seem to recall someone sent in their D7000 for service (maybe on that perception) and the main mode dial came back with a slightly stiffer detent.
The D7100 adds a central, press/unlock button. It's easy to use, though I didn't feel the D7000 had a real issue (I did, though, get into the habit of glancing at the mode dial if I had to yank the camera out of my bag). Only then did I notice the chance that the mode dial might have been inadvertently shifted.

Perhaps this post is the one you were referring to.
He used heat shrink tube.
Edited to add:
OOOPS! Miss read this to mean mode dial, not command and sub-command dial. But now that I think about it, I don't recall anyone mentioning a DYI fix other than sending it of for service for those dials.

You can't put heat shrink tubing on the front or rear command dials, at least not without disassembling the camera. These are the ones on the right as you're holding the camera in front of you, below the shutter release and immediately behind it on the back of the body. Also sometimes referred to as the main and sub command dials.
Theoretically I suppose you could put some heat shrink tubing on the mode dial, the one above the release mode dial, and if you're lucky it'll engage the little white nib thing enough to tighten up the dial without binding it, but it sounds like a #### shoot, and I don't actually think that's the dial you're having problems with.
Actually the reason I'm posting this is because there seems to be some confusion about what these various knobs and dials are called.
