Ive just carried out the basic15hrservice on a pair of F32s, removing lower legs , cleaning etc as per Mojo instructions; All has gone fine until Ive tried to get the nut on the LEFT (air chamber ) leg torqued to 5.6nM—-it just will not tighten properly, the threaded end just spins in the outer housing. Right leg no problems, tightened just fine. What do I do to get the left leg properly tightened up??? many thanks for help on this !!

is there pressure in the air side? if not put some in. compress the forks a little and try again.

Yes about 70psi already

compress the forks a bit, awkward to do but gives the push rod something to bite against and stops it spinning.

Tried that too but still spins……
