Re: Help, Vibration at 55 mph...
I had this on my TJ, where balancing did not help. I rotated the tires,
front to back, and it went away. That might be a cheap short-term answer.
Also on the Sienna the wifey bent a rim just a bit that caused a shudder
over 65, put it on the back until I got a new rim and that mitigated the
effect greatly.

Re: Help, Vibration at 55 mph...
Do you have a narrow cupping pattern on the inside margin/surface of
your front tires???
If yes, Pull the bolts that attach the trac bar and inspect for
deformation of the attachment bolts and the frame portion of the
system. . The Right side uses a bolt whose threads will 'gall' into
the frame attachment (Original vehicles came with a totally threaded
bolt ... instead of a proper shoulder bolt/). The Left side attaches
to a secondary frame mount and the attachment can 'egg' (deform). With
both sides of the attachments deformed the play slop can 'add up'.
Do this test: key in ignition to unlock steering column, engine off,
rotate the steering wheel back and forth while looking at a far distant
object over the hood. If the far distance object is moving when you
oscilate the steering wheel ..... probably excessive slop in the trac
bar (or its attachments) - the relative soft tires will add a bit of
side to side play when you oscilate. If you perceive more than just
tire movement when you oscilate the steering wheel, have an assistant
oscilate the steering wheel while you crawl under the vehicle and
check/feel every connection of the trac bar .... *and its frame
attachments*.
Been there..... drove me nuts until I found the problem *on the frame
attachments* - galling of the bolt/frame and egg shaped hole on the
subframe attachment. Acted JUST LIKE DEATH WOBBLE!!!!!!!
Hope this helps.
