Your welcome, glad you found the video helpful!
I used fishing line going front to back equal distance from center of wheel tided to jack stands. I measured from rim to line with caliper and figured amount of toe in by figuring difference between center to center of the tire to rim to rim. Your toe-in measurement will be proportionally smaller by the center tire mesurement is to the rim. Make sure your rims are straight by lifting the tire and spin the tire using something like a rod attached to a jack stand. Now simply subtract the front meaurement from the back. Three other things. Level ground, steering wheel tied straight ahead and I used two plactic place mats from the dollar store to allow the the front wheels to move. Wiggle the wheels after each adjustment to make sure of proper measurment. If you have independent rear suspension do the same for rear. Tools, fishing line, tape measure, four dollar store place mats, claiper or fine scale measuring ruler, calculator or smart phone. If your front and rear wheels are different width set your string equal distance from the center line of the car. The distance between the line has to be the same front and rear and equal from center of the wheels front and rear. Idea is to get to parallel lines to the center of the vehicle. Most cases toe is all you need or can set on most cars.
You should have measured the distance between the two tape measures and make sure that it was the same on both sides so it would be square. Because if a 1/16 of an inch makes a difference, then your tapes having different gaps would definitely affect your outcome

Not a bad. Ensuring both measuring tapes are accurate to each other is a smart move.
Thank you. I have been using a straight edge to make marks on the driveway but I like your way better, I will try it next time. Wish Harbor Freight made a cheap setup. Would be nice to gauge off the rim instead because the tires aren't always perfect and the raised letters get in the way.
For those who are interested to 4 wheel for I.F.S. front end use a string at centerline of front and rear wheels to check. With string tight around both tires you can see if they are out if one side of your front tires are not touching the string

Another problem is that tires are far from perfect. I have tried this and found that as the tire is rotated, the dimension changes because of variations in the sidewall rubber. To be accurate it must be done from the wheels, as a shop would do it. Yet another problem is that as you extend outward where you measure, at the tire tread, the toe dimension will be far different from what it would be measuring from the wheel.
Only just started to watch and straight away my thought is it Needs to be off the wheel not the tyre wall. Wheel is fixed solid point tyres can flex/bulge

The wheel would be best. But in a pinch if you just need a quick and dirty alignment, the tire does work. Not the best. but it works.
Here’s my comment….while I like the idea overall, some considerations….first of all tires and wheels almost always have runout….so my preference would be to determine where the runout is….using a dial indicator….or something as simple as spinning the wheel and marking the high spot (wobble) on both tires and clock your placement of the cross bar in the middle of runout (splitting the difference on both sides.) Also on your jeep, and my Honda crv (had a wreck and bent front end parts, which I fixed…hence my need for a cheap alignment), you could also of utilized the slot in your wheels, and used one of your bungee or ratchet straps, through that slot in the wheel just to grab your slotted angle at the mid point and held it that way. Also, toe adjustments are usually given in degrees of angle, and 1 degree of angle, is 1” at 57.3 (or 57 1/4” works too) inches from the pivot point of your wheel, so if your car calls for 1/8” toed in, (2) 6ft pieces of rigid angle held on like your slotted angle, you could measure out front @ 24” and out at 57.25” and get a pretty precise toe adjustment. Not sure your really short angle is all that precise, since if you extrapolated your measurements out even 57” out front, your adjustment would be within spec. Also I would go drive your Jeep, and pull it in, again and set up your toe alignment setup again and see if it was truly repeatable, meaning did your adjustments still match what you set on the video….I’m thinking since if there is any tire/wheel runout, it might be off perhaps a decent amount, but again I like the easy idea for attaching the bar to the wheel, and that it measure toe with the suspension loaded. Nice video.

Furthermore, once you determined where your runout is, and your best place to put your bar, you could make up 4 blocks (or dowels), all accurate to one another (3d printed, aluminum or even hardwood), to place on the surface of the wheel and get off of the tire entirely, which would increase your accuracy perhaps by a lot…..fyi, food for thought!
I would make sure to put even tire pressure in both tires to make this method more accurate .. but I would try this method in the future 👍🏾

You can't adjust toe per side on a solid axle. Solid axle vehicles operate on Total toe. If this was IFS I'd completely agree with you. Though I do admit, that this method (using the tire as a reference) is not the most accurate. It would be better to bolt/strap the straight edge to the hub directly.

Incorrect. You can’t independently set toe for a solid axle vehicle. They are tied together. Toe for a solid axle vehicle is measured in total toe. I agree with you for IFS
The only problem I see with this method is it doesn't include individual wheel alignment from side to side using the rear tires as a reference. So yes the tires will have a good toe adjustment between the front tires but may not be in alignment with all four tires.

On a solid axle, not sides adjust together. Your seeing me adjust over all toe. One side can not be adjusted separately from the other.
Any measuring device would have to reference off the rim. Alignment machines take into account wheel runout and track . The only thing you can set is toe with any of these hacks. Where you have your straight edge would be highly inaccurate.

Not true. Measuring camber is also very easy using a digital level or angle finder, or even with a level, a ruler, and a basic understanding of simple trigonometry. Caster can also be calculated doing a wheel sweep and using a digital level/angle finder. Just takes a little more math. You do realize that alignments predate digital alignment machines, right? ;)

The wheels can not adjust independently on a solid axle. They are adjusted together. The measurement here is overall for both wheels.
If you have a taller car, it is easier and more correct to measure by marking the inside of the tires at hub height, measure with a tapmeter, roll forward, measure again and adjust. If it is a lower car, measure the outside, angle off towards the floor, roll forward half a turn, measure again. kzread.info/dash/bejne/lJh-y7F8qrzKl9o.html

This is very wrong. If you rely on the tire to make the alignment it may be inaccurate. There might be some sort of deviation in the tire surface at the point where you set the straight edge. Also if you rely on the rim that also might be wrong because there may be rim deflection. Best to attach an extension from the hub bolts past the tire surface and then use the straight edge method. Depending on the number of bolts bolts on the hub remove two and insert properly threaded longer bolts, or bolt extensions add a locking nut to prevent unintended loosening. Then you can attach the straightedge making sure the length of extension are exactly the same. This measurement is important because any variance is multiplied at where you want to measure toe adjustments.

You do not. On a solid axle vehicle the axles are either centered or they are not. You center the axles based on their location to the chassis instead of each other. A simple front end alignment that most shops preform address toe and maybe pinion angle. Those two adjustments have no relation to the rear axle. Most shops do not preform a 4 wheel alignment unless you specifically ask for it. Even than, solid axles have such few adjustments on them it’s not really needed. The rear can only have its pinion angle adjusted and be centered under the vehicle. The front is normally toe, pinion angle, and centered under the vehicle. Ifs is of course a totally animal.

We are not aligning a front wheel drive car here though. The only syncing, as you put it, that needs to be done is ensuring the solid axles on the front and rear are centered under the vehicle. This is commonly done by measuring to the frame and not to each other. But again, this goes outside the realm of a normal front end alignment. A 4-wheel alignment is only needed, if something changes. I.E. something is broke or changed out on the rear axle. Even at that point, for something like a Jeep, it's hard to justify a 4-wheel alignment. Solid axles just do not have that many adjustments on them. Pretty easy stuff compared to modern IFS.

Toe can be adjusted at home with numerous techniques, it’s not rocket science, caster more than either toe or camber is a little trickier, but again it’s math. Do alignment racks work easier for repeatable results on nearly every make of cars and trucks….sure, but again he’s adjusting toe, on a solid axle Jeep, his own Jeep, good god man, you sound like an idiot! People adjusting their own toe adjustment don’t need 30-50k on an alignment rack. They also don’t need to spend $100 for an alignment for simply adjusting their toe! I was a mechanic for better part of 20 years, got my start at Goodyear, by the time I left, I had done 100s of alignments, again the alignment rack is for quick repeatable results on most makes and models, for profit. The earliest alignment equipment used on cars, was primitive by todays standards, but used by a knowledgeable person, they could do work on par with todays techs. Do yourself a favor, and put yourself on a timeout, cause your the one spouting nonsense!
"Quick, easy" and wrong. Without a reference to the rear wheels, that are square on the vehicle, you have no idea if one or both front wheels are toed in properly. One front wheel could be perfectly straight and the other front wheel has all the toe in and you'd still show the toe in dimension that you want. You didn't address whether or not the steering wheel was straight either.

@@EmbarkWithMark The axle type has nothing to do with it. Like I said, without a reference to something that is known to be straight and square, the rear wheels, you have no way of knowing which way the front wheels are pointed. One front wheel could be perfectly straight and the other wheel toes in 1/4" and that would be wrong but it would still measure to be correct. The exact way a so called alignment shop left mine. On any solid axle a tie rod goes from one steering knuckle to the other. One end has a tie rod end that is threaded and adjustable. You need to remove the castle nut, remove the tie rod end from the steering knuckle and make the adjustment there using a straight line from the rear. It must be reinstalled to make the measurement. Repeat as necessary. I used a DeWalt 3 plane laser and used the magnetic mount to hold it to the rear axle hub and squared the laser to the rear wheel. It then provided a straight line to the front where I could measure from the laser line to the front and rear of each front wheel to make the adjustment. You can put a plastic bag under each front tire to make it slippery so the wheels can move easily without moving the entire vehicle as it is adjusted.

So, a 4 wheel alignment is always best, and I am not going to argue that using your method does not work to do a complete alignment. However, the adjustment you explained on the tie rode it self does not make sense to me. Since its a solid bar straight across from one tire to the other, any adjustment lengthens or shortens the entire bar. Even if you where to screw one tie rode all the in and leave the other all the way out both your tires will adjust at the the same rate since the length of the entire tie rod is being changed. Here is some info to better explain this garage alignment: www.quadratec.com/c/reference/jeep-tj-driveway-alignment Is this method a complete 4 wheel alignment? No it isn't. However, this is an alignment that can be done in any garage very easily. Mostly because the rest of your alignment should not be changing, if it is then there are other issues. The plastic bag idea is a smart one. You can also use jack stands under the axle it self. I know someone who uses two pieces of HDPE sandwiched together for each tire. He jacks the jeep up, places two of HDPE on top each other, then lowers the tire on to them. Very slick surface.

On a Dana 44 axle like this Jeep has tire wear likely would come from Caster or camber. On a Dana 44 camber and caster is set when the axle is built by Dana. Changing caster would require the knuckles on the end of the axle to be cut off and re-welded. Small camber changes can be done with offset cams between the steering knuckle and the upper and lower ball joint, but in many most cases to much work for little gain. This guys method of setting toe is just fine, racers have been doing it this way forever.....
