wheel alignment
« on: December 14, 2017 - 09:15:33 pm »
for what its worth, I have some uneven tire wear up front,
and am adjusting toe-in/out in the garage. Have taped a cheapy
laser pointer to a rod, then taped the rod to the sides of the front
tires. The laser pointer then makes a mark on the garage wall, and you
can adjust toe and watch the laser point change.

Nice tip!! :thumbsup: :thumbsup:

ya, came in handy, as I was originally turning the linkage the wrong way.
Gotta have the steering wheel locked, then jack the front tire
so it is just touching the ground, so it will turn easily, but not rotate.

Bad mistake jacking the front up as the toe in generally increases, the vehicle must have the vehicle weight on the wheels, I even give the front a bounce to make sure the front has settled. Is the steering box in its central position, after many years of mechanic's playing with our cars things like that can be out which then causes the driver to sub-consciously turn the steering wheel slightly when driving straight, the camber of the road needs to be taken into consideration.
If the tires are wearing it can also be the Camber out, have you checked the ball joints, bushes etc.

No, haven't checked all of that stuff. Probably due for an alignment shop appointment. But even with the front jacked up, I then moved the toe outward about degree or two, which I'm hoping will take care of the wear I was seeing on the outside inch of the left front tire. The right tire looks fine. I had replaced the tie rods and some ball joints last year.

When vehicle is jacked up the toe-in increases, don't ask me how much as it depends on the vehicle.
If you are considering having a proper front end alignment and based on only one side wearing according to your post this is what needs to happen.

I still do not get notifications from this forum so have to check through many posts if an answer is required.   :villagers:
