With the chain tension adjusted, you now have to align the axle. CSC recommends measuring the distance from the swingarm bolt to each side of the axle bolt (

If you don't have a metric ruler in millimeters or a yardstick to 1/16 inch, you can also use the axle alignment marks on the swingarm as described below. This is less exact but close enough.
The axle goes through a small bar on the left and right swingarm. On the swingarm below it, you can see a set of alignment marks. By comparing the position on the left and the right side, you can make sure the axle is straight across.
- On the right side of the bike, tighten the outside locknut until the alignment is the same as the left side.
- Re-check your chain tension. Readjust the left side if necessary and then readjust the right side to match.
- When the chain tension is adjusted and both sides match, tighten the inside locknut.
- Make sure all locknuts are tight and then re-check the chain tension and alignment marks. They should all match. If not, loosen and readjust.
- Lastly, tighten the axle nut and bolt on both sides.
