TROUBLESHOOTING COMMON SOURCES OF NOISE
Table
1.
NOISE SOURCE
HOW TO CORRECT IT
WHEEL QUICK RELEASE
Remove the quick release wheel; inspect the skewer, lever, and frame for damage. Tighten the
quick release, very tight.
REAR DERAILLEUR HANGER
Remove the hanger. Clean and inspect the hanger and the dropout. Apply a light film of bike
grease between the hanger and dropout. Apply Loctite
242
(blue) to the hanger bolt threads and
tighten to
5
N•m (
44
In•Lbs). Be sure to check alignment of derailleur following remounting. Be
sure to readjust wheel quick release so it is very tight.

LEFTY CLAMP BOLTS
Apply Loctite 242 (blue) to the bolt threads and tighten clamp bolts to:
Aluminum Lefty -
7
N•m (
60
In•Lbs), Carbon Lefty -
9
N•m (
80
In•Lbs)
CASSETTE LOCKRING
Follow manufacturer’s recommendation for service.
SHOCK MOUNT HARDWARE
Remove the mounting hardware and rear shock. Clean and inspect the shock bolts, shock bushings,
and frame and swingarm mounting points. The shock bolts should be straight. The shock bushing
should be in good condition and frame and swingarm mounting points should be smooth, without
signs of deep scratches,heavy wear, or other damage. A light film of grease can be used where the
eyelet reducers (bushings) rest against the frame. Don’t grease the bolt shafts; it can attract dirt
and cause premature wear. Reinstall shock with the head of the long bolts on the non-drive side.
Apply Loctite
242
(blue) to the shorter bolt threads and tighten to
5
N•m (
44
In•Lbs).

Obtain replacement shock bushings from the shock manufacturer.
SWINGARM PIVOT ASSEMBLY
Remove the pivot axle nut, pivot axle, and bearing spacers. Clean and inspect the parts and
frame pivot. Check for signs of excessive wear or damage. Check the frame pivot axle hole. Wipe
clean the swingarm pivot bearings with a shop towel. The bearing should appear to be in good
condition, seated firmly in the swingarm without signs of corrosion or mechnical damage. Rotate
the inner bearing race with your finger. Rotation should be quite and smooth. The bearings should
not feel gritty or rough.

BB AND CRANK SYSTEM
Follow the manufacturer’s recommendation for service.
A POTENTIAL SOURCE OF NOISE
If addressing ordinary maintenance issues and the specific troubleshooting information listed in Table 1. does not eliminate noise, , a
rare condition in the swingarm may be present.
The condition is caused by a small non-structural plate located inside the swingarm between the main pivot and seat stays. When
the plate moves under a load, it rubs against the pocket in which it rests. This creates a “creak or click” sound. Only swingarms with
codes in Table 2. can have this condition. The condition is rare even in a swingarm with the code. The test to confirm the condition is
explained on page 2. For questions about the test, please contact Cannondale Tech Support.
