Before I bought my 85 4-Runner in about 1996 and after I had excessive
tire wear on the outside of my tires (Goodyear Wrangler AS P235/75R15)
and about 2 years later I bought a new set of the same tires and
decided to pay a local Michellin tire dealer $30+tx to computer align
the front alignment (I don't think he even aligned them,I think he
ripped me off,what's new?) but after 40 000 KM I noticed that the new
tires have excessive wear on the outside and I usually have them
rotated every 5000 KM.
I don't want to take them again to a tire shop for alignment as I have
spent lots of money of my truck as most mechanics are crooks so I
would like to know if there is a manual way to align the front tie
rod.I have the Factory service manual for my 85 4-Runner.
Thanks in advance.

I used to see this on my '87 4Runner, it was due to low tire pressure. It
was also evident on the inside edge, but much less so.

My guess is too much toe-in.

Tape measure is all you need, mark both tires at the 3 o'clock position,
measure tire-tire, record separation. Roll foward 1/2 revolution until mark is
at 9 o'clock, measure
tire-tire (same point). Set toe in to 1/16" - 1/8" (that is you want the front
separation just a little less than the rear separation.
