Yes, you are correct, you take the measurment on the back side of the
tires, and then compare it to the measurement on the front side. The
pictures only show the tool in the front position. Sorry if I
created confusion. I was just trying to show the construction of the
tool and its placement.
Let me run through the procedure.
First tie, or block, the steering into an absolute straight ahead
position. It is important that the steering not move. (I used a
bunge cord from one handle bar, stretched behind the seat, then
attached to the other handle bar.)
Put a piece of tape on each tire and mark a + on it. Placement isn't
too crititcal, just try to get it in the center.
Place the tool behind the tires, and align the + on each wheel with
the pointer on each side. (I mounted the upright arms to the bottom
bar using a slotted angle bracket and wing nuts, so I could just
loosen it and slide it into alignment with the + then tighten the
Then move the tool to the front side, rotate the two + marks on the
tires to the front side and compare the readings.
It should be zero to very slightly toed in.
If adjustment is required, loosen the lock nuts on tie rod, on one
side only, and make a small adjustment. (one nut will be a right
hand thread, the other will be a left hand thread) A very small
adjustment will result in a fairly large change in toe. Once adjusted
lock down the lock nuts and recheck.
You should be able to do this multiple times and get the exact same
I hope this is now clear. Sorry if I confused everyone.
