I had my Vanagon up on blocks,once.Real concrete blocks. The blocks
crushed,and the Van came crashing down  on the brake drum. The drum hit
concrete.An imovable object. Well, the weakest link was damaged. The
Vanagon. I had a pulsating in my brake pedal. Could it have been a bent
brake drum? A bent wheel bearing? A bent hub?A bent stub axel? Could have
been all the avove.I didnt want to replace each, trial and error. Each
could have been at fault.What I did was to go to a junkyard and get a low
mileage hub and brake assembely.Had a stub axel in it. A backing
plate,bearing,housing,ext.I replaced them, all in one fell swoop.The
pulsating went away.To this  day, I do not know what component was
damaged.Perhaps each was a bit bent. I had no noise as you tell.You say a
tire blew out? Are your lug nuts tight?
