OK...

sorta kinda the same thing.....

My guess is inner CV joint.  Throwout bearings sound sorta like a whoosh,
which subsides (often) fairly quickly.  When my inner cv went, it sort of
ticked under deceleration.  Steering side to side will put load on the CVs,
sorta like acceleration, as the outer wheel is starting to rotate faster
compared to the inner.  Make sense sorta?  That'd be my guess.  Could be
outer, too, I suppose, but in my experience, the outers will not click
while decelerating, but feel more like a warped rotor.  I'm sure an outer
can click, however - mine did not.  Anyhow, I'd look at the cv joints, take
them apart, look for grooves worn into the outer part of the inner joint,
see if it looks as if the balls have room to move back and forth, ahh, that
does not make sense.  With mine, I could temporarily "fix" the problem by
repacking them with grease - maybe grease all four, as they sit (if it is
questionable as to whether they are worn), drive it, see if it changes.
Best of luck!
