[T3] Fan Belt of Not? (squeal)

[J. Jonik]

Looking around in and around right rear wheel, a maybe source of the squeals, it turned out that the hub nut was Finger Loose....but held in place with a good cotter pin. In fact, the hub plate (that the nut hold in) was out, maybe a thread width and a half.
   That hub plate is duly tapped back into place, hub nut is tightened (using a very dull chisel) to bang it into good cotter pin hole alignment, and there's no squeals after two test spins around the block.
  Is it possible THAT was cause of squeals?    Or, maybe too early to tell?

T-III,
 Std. FI '71----? I thought that a strange squeal coming from rear of 
car was the fan belt, so I changed it.??? There's still a squeal.?? Belt
 tightness is correct.? 

? It sounds like two turkeys serenading 
each other...not too screechy, but loud. ? And it stays at same pitch no
 matter what car speed. ? ?? BUT...a friend in the passenger seat the 
other day thought the squeal was more like from the right rear wheel 
area.? ?? If so, how can the squeal not change pitch depending on speed 
and wheel rotation?
Squeal never happens at idle, even if revved.

? What in rear wheel or suspension area or something could squeal like that?

One
 more thing.?? Apparently the dowel, or dowels that hold bearings in 
their crankcase positions have, over time, widened their holes in the 
case so that I now have a little too much in and out play in the fan 
pulley.? Will have to put in my one remaining spare engine one fine 
day.?? Could that extra play in the fan account for belt squeals?...or 
other squeals? ? ? ? (It accounts for the rattlesnake noise that also 
comes and goes...but....)

Could the slight excess end-play cause the crankshaft oil seal to squeal?
