This tool is not used to do an alignment. This tool is used to set camber back to the same place it was after you remove or replace a strut. Some struts are adjustable and have an oblong hole in them. This is used to make a camber adjustment by moving the strut in or out slightly and tightening the bolts back up. Camber is how much the top of the tire tilts in or out and is measured in degrees. When camber is changed it also changes toe. Toe is how much the tires point in or out as viewed from above. If toe is out just a little bit it can wear the inside or outside edge of your tires relatively quickly. I use this tool when I replace struts. If you don't, it is a pain in the ass to adjust camber with the tire on and the alignment machine installed on the rim. The two large strut alignment bolts are next to impossible to reach and adjust to the proper position because the tire is in the way.

For best results use these directions:
.
1. With the vehicle safely supported remove the wheel.
2. Slightly snug at least two lug nuts on the brake rotor so it does not tilt.
(You may have to buy 2 if they have a chrome cap on them preventing them from being tightened down on the rotor.)
3. Install the tool on a flat portion of the brake rotor and level the small level first.
4. Turn the knob on the bottom to zero the large level.
5. Remove the tool in a way not to touch the tilting level or adjustment screw.
Put it in a safe place where it won't get knocked out of alignment.
6. Mark a wheel stud and the brake rotor in a way you can install in them "both" in the same position.
Remember the position of the marked wheel stud (ex. the 12o'clock position)
7. Perform steering or suspension work.
8. Rotate the hub so the wheel stud is in the same position as when the tool was leveled.
9. Install the brake rotor over the "marked" wheel hub in the same exact position it came off
This assumes the hub and brake rotor are the 2 piece kind (like most), not the 1 piece design
10. Install the tool in the "same" location and snug at least two lug nuts so the brake rotor doesn't tilt.
11. Move the tool in a way to level the small level (Do not touch the adjustment screw)
12. Move the strut in or out and tighten the adjustment bolts when the large level bubble is at zero again.
13. Recheck after tightening adjustment bolts that it is still at exactly zero.
14. Remove the tool and install the wheel.
15. Tighten the lug nuts to manufactures specified torque.
16. Make sure all parts removed were properly reinstalled.
17. Pump up the brake pedal if you had to compress the brake caliper piston to remove it.

This tool is better than the "Tool Aid" brand one I previously had. It has a second level (side to side) which allows you to place it back on more accurately. This also has an adjustment screw rather than physically having to move the body to level it. I used epoxy to hold my magnet in. Save the cardboard box with Styrofoam it comes in to protect it.
