If you're experiencing play (unwanted movement) in your headset, or a rough grinding when you turn the bars, it's likely that it's time to service your headset or replace the headset bearings.
Most modern bikes use two sealed bearings positioned at the top and bottom of the head tube. We've put together this simple video guide to show you how to service the headset on such a bike. Different bikes come with different headsets, so a selection of common types are displayed below. Written instructions for this task are also outlined.
Some of the advice that follows should be seen as a temporary measure, useful in order to stretch out the life of your headset until you can find time to get it replaced. If the following steps don’t get results, or you’re still concerned about safety after the adjustments, then get the job done professionally by your local bike shop.

Tools required
- Headset wrenches (32 or 36mm)
- 4, 5 and 6mm Allen keys
- Resin hammer or block of wood and hammer
- Grease and citrus degreaser
- Torque wrench
- Thin threadless headset washers (www.hopegb.com)
- 5/32 or 1/8in loose ball bearings or headset cartridge bearings
How to diagnose and adjust a threaded headset
Bounce the front wheel off the ground a few times: a rattling sound indicates the headset is loose. If the bars lock in the middle and point straight then it’s either too tight or the bearings are heavily worn. Holding the front wheel or frame between your legs, with the bars as leverage, carefully place a 32mm headset wrench over the locknut and turn anticlockwise.
