R34 Windscreen wiper movement

[DatsunBanana]

Just wondering if this is normal ... if I lift the lower part of the drivers side wiper arm it rises by a good inch as seen in the pictures attached. It feels like it's against spring pressure somewhere under the scuttle panel where the motor is. I think it must be right to allow for the wiper angle to change as it comes up the windscreen but thought I'd ask in case it's the reason for my squeaky wipers.

Thanks.

It maybe be normal if there is a hinge lower than the photo shows but normally there isn’t. The arm is splined onto the tapered shaft and if the nut is loose it allows it to pivot as shown in your photos. If the nut is loose it’s only a matter of time before the spline strips. 

 

Tl:dr. Pop the bonnet and make sure it’s tilting at a hinge and not at the motor. It looks wrong and I think you’ll have to pry up the cap hiding the nut and tighten it.
