Even with a solid rear axle like yours has, there is a possibility of a toe
or even a camber concern.
A fairly easy and very accurate way to measure rear toe - make a chalk mark
about mid tread face towards the front of the car. Measure that as closely
as possible with a tape measure. Back up so that the tires make one half
revolution (the chalk marks now face towards the rear) and measure again.
The difference between the two measurements should be zero or very, very
close - 1/16th or even 1/8th of an inch difference is no big deal but we
should always be mindful of any uneven tire wear patterns originating on the
Rear camber, to have any meaningful measurement, should be done on an

before to discover if there are any pre-existing conditions that I need to
consider.... and after to be sure everything is right and that the steering
wheel is centered.
The rear wheel measurements *should* be correct as long as the tech hasn't
fudged his machine set-up. Since you have rear numbers on your print out, we
know that the tech has selected a "four wheel, centerline" alignment. When
he attaches the alignment heads to the wheels he would have to perform a
compensation for run out - not a big deal, but the solid rear axle can add
some "fiddley fartin'" to perform the task - especially if it is a limited
For the wheel balance issue... there is always the chance that a weight has
been knocked loose or off..... this would be a problem with whoever
installed the weights. If the weights are securely attached, the tech would
have to be real "special" to knock them off during the alignment process.
FWIW, I do come across vehicles that have either the wrong style weight
used, stick on weights applied to a dirty surface (I like to add a strip of
duct tape if the weights are out of sight - just for peace of mind) or even
"old stock" stick on weights (the adhesive has a nasty habit of drying out
For toe being the biggest cause of premature or abnormal tire wear....
almost 40 years of experience tells me that this is an incontrovertable
