Have you been lubricating those joints regularly?

In which manual does it state that these joints should be lubricated?

It does say in the pic he posted that anti-seize may be used for installation of those joints.  I was just asking the question.

It is required for the standard ball joints, as per the Rotax Installation manual (78-00-00, Para 1.1):

"The 4 ball joints must be used to avoid damage due to vibration.  All ball joints have to be greased regularly with heat resistant lubricant (e.g. LOCTITE ANTISEIZE) to avoid gripping and seizing of the joints. Be aware that locked up stresses cause cracks."

I too was just asking the question. Your question sent me to the manuals, but I could not find anything that indicates that these joints should be lubricated, except for assembly, if necessary. If lubrication is necessary, I would like to know.

MML 5-20-00, pg 3 also says, under "Recommended Inspections", to carry out inspection: Of the exhaust unit (where necessary, replaced application of LOCTITE Anti-Seize).  In that case, it doesn't get too specific about exactly where.
