Piper nosewheel steering linkage

I have heard differing accounts of whether the rudder pedals turn Piper
nosewheels when they are not on the ground. I know Cessnas have some sort
of cam arrangement which disengages the steering mechanism when weight is
taken off of the nosewheel, but there's nothing definitive about this my
Warrior POH one way or the other. Can anyone who has worked on the gear
settle this? I realize all Pipers might not be the same, I'm talking mainly
about the fixed gear singles. The issue came up when I suggested to someone
that a swerve on touchdown might have been due to not neutralizing the
rudder before the nosewheel touched down, because I had heard that there was
a fixed linkage.

Thanks,
Jeremy
