Info from Turner
How long / how old is your bike it may need new bushes if you have never greased them!

Grease the pivots once every 10 hours of wet riding or
less frequently in dry weather. The pivots have extremely
tight tolerances and the rubber o-ring seals do a good job
at keeping debris out. When you do get ready to grease,
make sure to clean the zerk out well with a toothbrush or
nappy rag before greasing so you don’t push any dirt from
the mouth of the zerk into the pivot. Use Manitou Prep-M
or a similarly thin viscosity grease (Turner recommends
Prep-M). The pivots are manufactured with extremely tight
tolerances and grease that is thick and viscous may not be
uniformly distributed through the pivot.
Because the chain stay bridge is in the way, to lube the
main bb pivot you will either need a long needle or you
will need to remove the top shock mount and let the rear
triangle sag out of the way
