You gave me two new possibilities to investigate: out of balance
rotors, and bushings …

I should point out I cannot feel a pulse while braking, only the
shake, and that it seems to only occur while braking at highway speeds
(like when using exit ramps, freeway exchanges etc- not between stop
lights).

the truck only has about 55k on it (a 96) so the low milage only adds
to my confusion.

The shop I have been going to (a local Discount Tire) has lost my
business. They are always packed and always in a hurry (My tires were
filled well in excess of 40 PSI last time I left there)

I may just have a mechanic figure it out when I get the 60k service
done.

I paid for the "lifetime" balance and rotation, so I will go to
another location and see if they get it right. Balancing seems to help
somewhat, and then the shake gets progressively worse (I have done
this 2x since I got the truck in September of last year)

steering shake is much different then my brake pulsing. a rotor may be
square but out of balance. you can have it checked for both, off the vehicle
at a shop.

from some research, the good balancing people put a few small weights,
inside and out  as needed to get the best balance.

tires may need re-balancing after the tire goes thru tread wear, but i don’t
think so much that you would get steering shake.

my 96′ 4runner has minor steer shake, but i can only attribute this to the
large 265-70-16 tires and the wear on sterring bushings/components.

maybe you need some new polyurethane bushings throughout ???

all i can recommend to those worried about this when your auto is at the
shop, ask for them to use a torque wrench (or auto-torque socket) if they
must put on lug nuts.

lots of shops bear the ASE sign as a sign of competency. ASE should make it
so that lug nuts must be tightened to torque spec.

Also get a shaky steering wheel just driving, between 55-65 mph, but
it is not nearly as bad, but makes me suspect the tires are the
problem.

I have checked my alignment, rotors (on the front of course) and tire
pressure -the allignment is just barely out of spec (tracks reasonably
well), the rotors are fine, and the tire pressure is exactly as my
owners manual specifies for the tire size (26 psi front and 29 rear).

I have Toy alloy wheels and BFG AT/KO 10.5 x 30" tires … (is there
some special trick to balancing these that the guys at Discount do not
know?)

Any help with this would be greatly appreciated, I am really stumped.
