Hello my friends, today we'll have a video you have been waiting for a long time I'll show you how to measure and how to adjust the toe angle of your car The toe angle is the angle between the front wheels In a car, the front wheels are usually not parallel In many cases the wheels point inward in driving direction, this would be a toe-in or the wheels point outward in driving direction, this would be a toe-out In classic times you used mechanical toe gauges to measure the small difference (1 or 2 mm) in distance between the front and rear end of the wheels In our day even the DIY enthusiast can do this with an optical laser tool The price of such tools is meanwhile affordable for DIY use I use the so-called Trackace-Tool, thus some parts of the tutorial are specific for this tool The car must stand on a plane level ground and the wheels must stand in forward direction Go to the right front wheel and hold the wheel gauge to the wheel rim Place the laser unit at this distance to the wheel Half a centimeter doesn't matter Place the wheel gauge now on the left wheel It must touch precisely the wheel rim, select a place with no damages The wheel gauge must be horizontal, adjust this with the feet Before I switch on the laser a safety note Never look at the laser light directly, stand always aside the beam And take care that the mirror doesn't reflect the beam in your eyes Switch on and you'll see the spot Follow the spot and adjust the laser to the center of the mirror You'll see the spot on the ground I turn the laser up and you see the spot moving on the ground I miss the mirror on the right side I must turn the laser unit horizontally You see I approach the lower frame of the mirror, a little bit more and we are on the mirror For safety purpose I bend the mirror that it reflects the beam to the ground That's already the reflected beam I'm tilting the mirror slowly to bring the spot back on the other side Up to here is the reflected beam This is the incoming beam, and this is the reflected beam Thus, I must turn the laser unit a little The reflected beam must hit the scale After some search the beam is on the scale Adjust it precisely to the zero position by turning it slightly This is the trick of this device which works with one mirror only The left wheel is now absolutely parallel to the scale I'll move the mirror now from the left wheel to right wheel If the right wheel has another angle, the reflected beam hits another place on the scale I take the wheel gauge from the left to the right wheel, don't touch the laser unit Place it to the wheel and search the laser beam And we find a toe-out angle Here is the scale, 1° would be here The spot is on the 50' line, thus the toe-out is 50' I have the needed values from the workshop manual here The toe-out should be 15' +10' or -15' The 50' are out of the interval, thus we have to adjust the toe angle On most cars you adjust the toe angle with the tie rods On this Gold Mk 1 only the right tie rod is adjustable Here the tie rod end is connected to the tie rod When I screw out or in the tie rod here, the toe angle changes The tie rod is connected behind the hub If I want to reduce the toe-out, I have to make the tie rod longer Thus, I must screw out the tie rod out of the tie rod end Thus, I have to slacken the counter nut, I apply some rust remover For counting the rotations I make such a tape flag on the rod For the most German car you'll need 22 mm tools for the tie rod Best to use such a crow foot and an open-end wrench Slacken it with brute force The counter nut is loose, I can turn the tie rod at this hexagon This would be a quarter of a turn, as you see at the flag The resilience results from the boots, this will vanish later This is half a turn, maybe this is already enough I fasten it only a little for the measurement Let's measure again And we find a toe-out of 35' Meaning, that practically half of the way is done, it has been 50', now we are at 35' and 15' we would like to have Thus, another half turn and we are done And bull's eye, an argument for the high precision of the method We have exactly the wanted 15' for the toe-out angle Finally, we must fasten the counter nut I found 2 different values for the torque In one book I found 40 Nm in the other 50 Nm Thus, I'll apply something between 40 and 50 Nm And we have 40 plus something, the nut is tight I remove my flag and the job is done Today I have shown that such an easy tool allows a relative precise measure of the toe angle There is no need to bring the car to a shop Bye, bye, see you in the next video
