Why is it doing this? Time for a lube job? It does it when I compress the rear suspension (sit on the bike).

Many times it comes from the top shock bearing. Try cleaning/lubing that first.

You will also find the the small knuckle that bolts onto the swingarm at the bottom.
These are the first bearings to go dry especialy if you clean with a high pressure cleaner.
Strip your swingarm and regrease it is a worthwhile exercise and should be done every six months to a year. :)

Is that hard to do? I've had the bike since about.. June, and ride it almost strictly in the desert (very fine sand).
