A squeak is usually dry metal — a little silicone lubricant fixes it. A caster that catches or drags usually has hair wound around the axle — clearing it fixes that. A wheel that is flat-spotted or cracked needs replacing.
First, find which caster it is. Tip the chair onto its side and spin each wheel by hand, then turn each caster on its stem. The one that squeaks, sticks or wobbles is usually obvious. Most casters pull straight out of the base with a firm tug, which makes the rest easier.
If it squeaks. The noise comes from the axle the wheel turns on, or from the swivel where the caster turns in its housing. A small amount of silicone spray on both, with the wheel spun to spread it, usually silences it. Silicone is preferable to oil, which collects dust and fibers and makes the next problem worse.
If it catches or drags. Hair, carpet fiber and thread wind tightly around the axle inside the wheel. Pick them out with tweezers or a small flathead screwdriver, or cut them with a craft knife along the axle line, and spin the wheel until it turns freely. This is the most common reason a chair suddenly rolls badly.
If neither works, replace. A wheel that has gone flat on one side, cracked, or hardened so it skids on a hard floor will not recover with cleaning. Casters are sold in sets of five, from about $8 in the chair casters hub, so it is usually worth changing all five at once; measure the stem first — replacing worn office chair casters explains how.
Check the base while you are there. A caster that wobbles in its socket rather than in its wheel points to a worn or cracked base socket, not the caster. A loose stem that will not stay seated in a new caster is the sign; the base is then the part to replace.
