tire wear, one wheel only?

After we bought (privately) our ('99) Cavalier, we found that it had
been "totalled" earlier in its life.  Alas.  Mostly, this hasn't been
a problem.  However, the LF tire has excessive tread wear on the
inside corner - to the point of needing replacement after ~15K miles.
All other tires are wearing normally.

Since the RF tire is wearing normally, I'm thinking that this isn't a
toe problem.  I did a _rough_ check on camber (using a square and a
scale), and got about 0 deg on both front wheels.  The spec is 0 +/- 1
degree, which I think I would catch.

There is some lash in the steering linkage, about 5 deg at the
steering wheel.

I'd appreciate any thoughts on what might be happening.

TIA,
George

Tie rodeend, check on a rack see where the looseness is.

Should a tie-rod be loose enough that I can easily rotate it by hond over the balls? Several of my cars even w/ advanced
miles - their tie rods are relatively 'tight' to rotate or spin a little by hand. On the other hand I have one car that
I can grab either connecting rod and spin it back and forth relatively easily. Would that indicate the tie rod ends are
worn and should all be replaced (inner/outer)?

thanks,

Have you checked the "toe" on that wheel?

It's almost gotta be a camber or toe-in.  If those check, have a good shop
check for a "star" in the "frame".  This is where diagonal from lf-to-rr
cross rf-to-lr--distances MUST be equal.  HTH, s

Right. A good 4 wheel alignment might reveal this kind of problem as
well.

I've seen a number of vehicles going down the road like a crab (sort of
sideways). Even if the front is aligned by itself, if the rear isn't
square with the front, it requires a continuous steering input to keep
the vehicle from going in a circle.

   I've seen the same thing--1st I noticed was Chrys. products in the
70's--Darts, Valiants, etc.
   Also, even when they get the rear square with the front, if one wheel is
pushed back an inch +/-, like from the car's previous "total" the OP
mentioned, it still presents problems.  Have a good day!  s

Can incorrect toe affect just one wheel?  My picture is that the front
wheels would have to be pointed symetrically in order to drive
straight.  So, if (say) the left was toed out, you'd have to steer
right to compensate, causing both left and right to track slightly
toe-out, and they'd both show similar wear.

   George, IIRC, yes.  Car will have have a leading wheel and a following
wheel.  Just imagine, the steering wheel, on conventional older cars,
connected to the Pitman arm, on the left(leading) wheel, and linkage
connected the right wheel via a stationary idler arm--kind of a passive,
follow-the-leader affair.  HTH, s

Exactly, toe is a combination of both front wheels it cannot affect one,
only camber can as far as tire wear.

   GE, I'm sorry that I did not remember correctly above--listen to Shep's
reply about toe causing BOTH to wear.  He's right.  If toe is out, you drive
such that the 'amount out' is shared equally between the 2 tires, such that
both would wear.  My bad!  s
