Quick answer

The tension bushing keeps the headtube and fork snug so the handlebars turn the wheel properly. If you notice wobble or loose steering, it’s time to replace it.

When to replace the tension bushing

Over time, the bushing can wear down from regular use, causing a loose feel in the headtube. You might also see the handlebars not turning smoothly or hear a clicking noise when steering.

The bushing is identical for the top and bottom of the headtube. If one side shows wear, it’s wise to replace both to maintain even tension and prolong the life of the headset.

Step-by-step replacement guide

  1. Remove the handlebar assembly: Loosen the quick-release clamp or bolts securing the handlebar stem. Slide the handlebar and fork out of the headtube. Keep the small parts together so you don’t lose them.
  2. Take out the old bushings: Using a small flathead screwdriver or your fingers, pry out the worn bushing from the top and bottom of the headtube. Note their orientation. Check both bushings even if only one looks worn; they often degrade at the same rate.
  3. Install the new bushings: Press the new bushing into the top opening, then the bottom. Make sure it sits flush and doesn’t bulge out. If the bushing resists, use a soft mallet or the back of a screwdriver handle to gently tap it in.
  4. Reassemble the fork and handlebar: Slide the fork back through the headtube, reattach the handlebar stem, and tighten the clamp or bolts to the manufacturer’s torque spec. Overtightening can bind the steering; tighten just enough to remove play while allowing free rotation.
  5. Test the steering: Turn the handlebars left and right to confirm smooth movement. Lift the front of the bike and check for any play in the headtube. If you still feel wobble, double-check that both bushings are fully seated.
