Couple of weeks ago I had to repair my trusted XCs driveshaft bearings.
Things went well until a few days ago, when a metallic "clickety- clack" became audible at its rear CVT area. Not that dominant but constantely during idle and decellerating.
Well, CVT opened, listened, it came from inside or behind the clutch.
- clutch out and disassambled
- first suspects, clutch spring coils, were in place and good order
- roller bearing, small ball bearing and oilseals renewed
- completed and noise still there
- everything apart again
- SHORT STORY:
- this three guide pinions which make the drive face move on its boss, were AXIAL worn out for about 1/2 mm, so they moved sideways and caused this clicking sound/noise (pls see last pic for detail).
A new drive face assy was ordered, which set me back for a €95,- which is not that much but...
Smooth running at all rpms as it should be.
So, if you face a sound / noise like this from your rear CVT/CLUTCH, it might be drive face related.
I think this would have lasted another 10 or 20 K klms but better to have it mended.
