1782 steering noise
 

my 1782 has a noise sounds like fluid starving only on LH turns fluid is full with proper cub fluid any ideas

I had a 1864 that was doing something similar. Very loud. I changed the fluid and filter and it go a lot quieter.

As suggested change the fluid and filter. At minimum change the filter.
See what it sounds like.
Are the spindles free and lubed good? What I'm getting at is see if it is actually having to work harder to turn one direction?
