Changed the oil in the Carc (engine and gearbox too) several weeks ago. Now getting a leak of fluids onto the rear wheel. No indication of oil migration down the carc, so gear box et al eliminated. Also the rear end feels a bit squirrely under acceleration. I originally put that down to oil on the wheel but it does it in the straights as well.
I let the carc oil out and it was not fresh looking at all, rather it was a dull grey colour.
Taking the rear wheel off indicated a slight dampness/ leak from the seal, me thinks it would come out more quickly under load as both recent test rides of a kilometer out and back was enough to  make the rim and tyre quite wet.
The 1100 has 45,000 kms on it. I have had her for 2 years and put on 20,000kms. Oils have been changed every 5-6,000 kms (bit anal I know). This recent episode has come on very quickly.
I assume once the bearing goes it deteriorates quickly? I cannot feel any play however when I try to rock the rear wheel

Question; Is this a home job or one requiring special tools and expertise.
(note: I try to do most of my own maintenance but lack experience and confidence it matters such as this.)

Cheers.

Thanks for posting ghezzi. Looking at the work skills needed I think I need an appointment with Pete.

Only problem there though is that I'm away until the 19th of December! BUT!!! If you want to go up to Bungendore to drop the misbehaving one off I can arrange for a 'Loaner' to be available for you to use until I get back to fix it. It won't be the correct colour but it'll work!

side bar Mr Roper.... if CARC oil is found to have escaped forward into the shaft tube...

does that suggest that the gasket ring #3 (above) has failed, or that the boot #1 (below) has failed?? (or both  Sad )
