I had these same sort of symptoms on my 85 300D.
I had just replaced the engine, and soon after I started to feel more than
hear, something rough in the steering wheel and fuel peddle.
this was over the course of 3000 miles.
at first I thought, what`s wrong with the new eng? as time went on felt like gear noise, or roughness. the towards the end like snow tire type noise, but now loud.
changed the L/F tire, no change. finally pulled the hub and the inner bearing cage was starting to deform. replaced the bearings and races and
smooth as butter now. both hubs never felt hot.
