The knobs have a metal counterweight inside the top of the shift lever to give them better feel and, oddly enough, to prevent buzz. Well, to help damp movement under presumably normal conditions.

A few of mine have buzzed and I've been able to fix them. A glob of silicone RTV down inside, and squish the weight down into it... seems the simplest fix.

Let it dry for a few hours before snapping the number cap back in.

I had one with a buzzy number cap. I very neatly wrapped it in 2 turns of Teflon plumber's tape. I was actually barely able to see a thin white line all the way around and it looked kind of neat. This shut up the cap.

Sometimes the knobs get loose; there's no good fix, as it usually means the plastic inside of the knob is broken. If you like the leathery feel of an original knob, see your Volvo dealer for something close (And pricey, at about $22). The MTC knob sold by FCP and I'm sure, other suppliers, is smaller, harder, and sportier (I would say) than the original. It's also $9. Takes the original cap and pounds onto the lever the same as original.

I've got an MTC knob on my 90 745 and it feels great, very non-Volvo-ish actually, which for the shift lever might be a good thing. I put superglue on the lever before installing the knob too- if you've ever had one come off in your hand when going for 2nd gear, you'll want to do this too!

Enjoy it!
