Anthony here di WyoTech and we're going to be showing you how to do a three-dimensional automotive alignment today on your car four-wheel drive alright alright so be a demonstrating alignment on a Dodge Dakota today may be using our awesome hunter alignment machine it does tow caster camber with three dimensional view and we can also check our thrust angles so we'll show you how to do that today first step is to get the vehicle safely on the lift make sure that all the turn plates are put in all this slots in get the tires basically centered on the racks we had to push the truck a little further forward because it's too long so to do that next step will be to grab your trim things that he's grabbing right there which are computer sensors that feed to the hunter machine and we're going to set them up on the tires what you do is you get the bottom tabs in first right underneath the rim so if you can see that get those in first then pop the top ones in and this little screw mechanism puts it on there give it a good tug to make sure it stays on the tire and then your last step is to take this pin right here and lock it on lock it on the rim so that if this very expensive piece of machinery falls off it'll get caught by the hook so what this does is it sends a signal from the tire shoots it all the way up to that little computer sensor up there which feeds it to the hunter machine and it reads us our values for the alignment um once we've got all those on we're going to check them all make sure they're all in safe make sure all the hooks are on check your tire pressure the tire pressure needs to be about 35 psi for each tire and they all need to be around the same and you need to check your trim height here to check for sagging suspension parts otherwise your alignment will come out faulty so once we do all that and you have all that good to go then we can actually start our alignment procedure to check for our tow camber caster and thrust angle right now we're just leveling the truck what we do is we put all these turn plates down here and what these are doing is this is levelling the rack out so that the truck is sitting level so it doesn't roll back and forth so we so we have it off the ground right now just to check all the tire pressures so they can be a you know chest height and now we'll drop it down slowly and put them down on the centering pins and now they're down alright so we just completed the rolling compensation test basically I don't need to figure out how you you really car back and forth as computer tells you to and it gives you little arrows that you Center it on once it says it's centered you chock the wheels then you install a brake pedal depressor and you align the steering wheel using these kits right that would be the brake pedal depressing right there just goes up against your seat pushes the brake pedal and then we're also gonna want to line the steering wheel to alright so now we're just gonna turn the wheel back and forth so that it centers itself so then we can start the alignment procedure is turning the wheel gets it on the green no more right there okay good there right now since else go the other way keep going keep going keep going a little more again okay explain out night chief all good so now I straightens the steering wheel out and then we walk it it's not the steering wheel thing you then mount up against the seat keeps the steering wheel stationary well with you all of our measurements grass these are the measurements we're getting from our machine gun I throw single and we've got our caster camber in tow so we're well I can show you caster for one caster will be the forward and back movement here of the suspension like the strut assembly um your camber actually show you yeah yeah Marisa will be the movement this way that way of your tire when it's sitting flush and then your toe would be where the tire sits well as stationary so your tires could be bowed to the left or bowed to the right so thrust angle looks okay it's still in the green so we're gonna go up here to the front since we're not gonna touch anything in the back even though the back is what you work on first and as you can see our toes out alright so we got here is caster that we're changing it was about four degrees out before two remarks was in the red all we're doing is moving these little elliptical circles right here we have them on the front and back of the a arms and they just change just to show you how that turns and how that actually measures and the hole is not centered so when it when you're turning this pulls this in pulls actual a arm in and out exchanges your camber and caster which one again every time it turns that you're changing the measurement we're talking tenths of it every year seems it the wrong aggression so we turn it back the other way and it should Center is emitting once we edit centered all right so now we have the camera the caster just it in the green on the left side we will torque our bolts back down so they're tight so they don't back out use torque wrench don't use your judgment so for this side it's the same thing just gonna loosen up both of these a little out of round your circular things that basically change the camber and caster angles to the a arm so back them out a little bit so that we can adjust them and once we get them in the green we tighten them back up with a torque wrench with the vehicle torque specifications all right so our measurement for tow we're gonna do is we take this tire rod end right here just in that locknut back it out a tiny bit you don't wanna loosen it too much and then you'll put a wrench right here as well so you have two points you have one right here on this thing slotted for wrench and then you'll loosen up that locking nut and we're gonna do is you're gonna back this in in or out depending on which way your toes out if it's negative or positive and then once you get it in the green you'll tighten up that lock nut while holding that tie rod Black Card stationary and that hopefully it stays in spec sometimes it'll fill out a couple degrees so you just kind of play around with it sometimes don't have to go you know five degrees negative or positive when you're tightening it up and then it'll zero out once you tighten it because of that like initial movement of the talkin so that's how you do toe on most cars for the front it's gonna be the same on four sides toes definitely the last thing to do and also when you're doing alignment always do the rear end first because that directly affects your front end alright so after you've got your caster camber toe and your thumb angles on the grain make sure to do a print out and also make sure that you had a print out done before you actually worked on the car to show how it was beforehand and show how it was after after you do all that stuff you want to make sure to put all your tools away double check all your torque specifications make sure that you bolted everything back up make sure you printed the sheet out to show a customer show yourself that you actually did the alignment then you're going to want to take the car and get it safely off the lift make sure to remove the brake depressor make sure to take off the steering wheel locking thing make sure to raise the put the turn plate pins back in before you take the vehicle off the hoist lower the hoist all the way down slowly and pull the vehicle off and then take it for a test drive and make sure that it's actually tracking straight and not doing anything funny and then you're all done that's your alignment see you next time
