[T3] Alignment

[Keith Park]

Yea, check the front.  Its not that hard to bend a lower torsion arm up
front.

It took a little less than 40k miles for the tire to wear out on the inner
edge. What I don’t know is exactly when it started wearing. 

I got the tires rotated (front to back/back to front) and a 4 wheel
alignment on July 1st of this year. Then we went on a cross-country drive of
more than 7k miles. I never noticed the tire wearing like that when it was
in the front, but it may have started then (unbeknownst to me as I didn’t
even notice the tire was worn out until I had it off for unrelated reasons)
and then finished wearing in the back. Alternatively, it might not have
started to wear badly until it was rotated to the back. I’ll have to inspect
my new tires this weekend and see if I notice any unusual wear.
